WordPress Plugin: Contact Form To Any API

Introduction

In today's web development landscape, integrating forms with APIs (Application Programming Interfaces) is a common requirement. Whether you're building a contact form, a registration form, or any other type of form, the ability to send data to a server or a third-party service is crucial. In this blog post, we'll explore how to connect a form to any API, covering the fundamental concepts and providing practical examples.

Understanding APIs

An API is a set of rules and protocols that define how different software components should interact and communicate with each other. APIs act as intermediaries, allowing applications to access and exchange data with other systems or services over the internet or within a network.

APIs can be divided into two main categories:

1. Web APIs: These APIs are designed to be accessed over the internet using standard protocols like HTTP(S). They are commonly used for integrating web applications with external services, such as social media platforms, payment gateways, or cloud storage providers.

2. Internal APIs: These APIs are used within an organization or a specific application ecosystem. They facilitate communication between different components or modules of an application, enabling data sharing and functionality integration.

Connecting a Form to an API

To connect a form to an API, you'll need to handle the form submission event and send the form data to the API endpoint using an appropriate method (e.g., GET, POST, PUT, DELETE) defined by the API's documentation. Here are the general steps involved:

1. Setting up the Form

Create an HTML form with input fields for the data you want to send to the API. Ensure that each input field has a unique `name` attribute, as this will be used to identify the data when sending it to the API.

2. Handling Form Submission

Use JavaScript to listen for the form submission event. When the form is submitted, you'll need to prevent the default behavior (which would typically cause a page refresh) and capture the form data.

3. Preparing the Data

Depending on the API's requirements, you may need to format the form data in a specific way. Common formats include JSON (JavaScript Object Notation), URL-encoded data, or multipart/form-data.

4. Sending the Request

Use JavaScript's `fetch` function or a library like Axios or jQuery to send an HTTP request to the API endpoint with the formatted form data. The request method (GET, POST, PUT, DELETE) and any additional headers or parameters will depend on the API's specifications.

5. Handling the Response

Once the API responds, you'll need to handle the response data appropriately. This may involve displaying a success message, updating the user interface, or performing additional actions based on the API's response.

Handling Different API Requirements

Different APIs may have varying requirements for data formatting and authentication. Here are some common scenarios:

1. JSON Data

Some APIs expect data in JSON format. In this case, you'll need to convert the form data to a JSON object before sending the request.

2. API Key Authentication

Some APIs require an API key for authentication. In this case, you'll need to include the API key in the request headers.

3. OAuth Authentication

For APIs that use OAuth authentication, you'll typically need to follow a multi-step process involving user authorization and obtaining an access token. This process may involve redirecting the user to the API's authentication page and handling the callback URL.

Example: Connecting a Contact Form to an API

Let's consider an example of connecting a simple contact form to an API. You'll need to create an HTML form with input fields for name, email, and message. Then, use JavaScript to listen for the form submission event and prevent the default behavior.

Next, you'll need to capture the form data and prepare it according to the API's requirements. This may involve converting the data to JSON format or formatting it as URL-encoded data.

Once the data is prepared, you can use JavaScript's `fetch` function or a library like Axios or jQuery to send an HTTP request to the API endpoint. The request method (e.g., POST, PUT) and any additional headers or parameters will depend on the API's specifications.

After sending the request, you'll need to handle the API's response. If the response is successful, you can display a success message, reset the form, or perform any other necessary actions. If there's an error, you should handle it appropriately by displaying an error message, logging the error for debugging purposes, or attempting to retry the request.

Example: Connecting a Form to an Internal API

In some cases, you may need to connect a form to an internal API within your application ecosystem. The general approach is similar to connecting to a web API, but the specific implementation details, such as authentication methods and endpoint URLs, may differ based on your application's architecture and requirements.

For example, if you're building a single-page application (SPA) with a separate backend API, you can use JavaScript to send form data to your internal API endpoints. This might involve authenticating the request with JSON Web Tokens (JWT) or other authentication mechanisms specific to your application.

Conclusion

Connecting forms to APIs is a common requirement in modern web development, enabling data exchange between applications and various services. By understanding APIs and following the steps outlined in this blog post, you can successfully integrate your forms with any API, whether it's a web API or an internal API.

Remember to consult the API's documentation for specific requirements, such as data formatting, authentication methods, and endpoint URLs. Additionally, ensure that you handle errors and provide appropriate feedback to users, enhancing the overall user experience of your application.

FAQs

Q: What is the difference between a web API and an internal API?

A: A web API is designed to be accessed over the internet using standard protocols like HTTP(S), allowing web applications to integrate with external services. An internal API, on the other hand, is used for communication between different components or modules within an organization or a specific application ecosystem.

Q: Can I use a library like Axios or jQuery instead of the `fetch` function?

A: Yes, you can use libraries like Axios or jQuery to send HTTP requests to APIs. These libraries often provide a more user-friendly API and additional features compared to the native `fetch` function.

Q: How do I handle authentication with APIs?

A: Authentication methods vary depending on the API. Common methods include API keys (included in request headers), OAuth (multi-step process involving user authorization and access tokens), and basic authentication (sending credentials with each request).

Q: What should I do if the API response is not successful?

A: If the API response is not successful (e.g., `response.ok` is false), you should handle the error appropriately. This may involve displaying an error message to the user, logging the error for debugging purposes, or attempting to retry the request.

Q: Can I use the same approach to connect a form to an internal API within my application?

A: Yes, the general approach of handling form submissions, preparing the data, and sending an HTTP request to the API endpoint remains the same, regardless of whether it's a web API or an internal API. However, the specific implementation details, such as authentication methods and endpoint URLs, may differ based on your application's architecture and requirements.

How to Send Form Data Using Axios Post Request in React

Many developers use React, a leading programming language for app development. Industry leaders prefer React for cross-platform application development. A proper understanding of React and the library is essential to work well for the project. If you want to handle react project properly, you can hire react developer and finish the task.

As a React developer, sending form data to a server in react with the Axios. Processing axios is an important javascript library. It is the best way to make HTTP requests from a browser or nodejs. Individuals must understand how to use the Axios to make a post request and send form data.

About Axios:

Axios acts as an HTTP client for JavaScript that works in browser and node.js. It is an easy-to-use and lightweight library that delivers the perfect interface for HTTP requests. Axios can build on top of XMLHttpRequest API and fetch API.

On the other hand, it supports promise API and intercepts responses. Axios is responsible for transforming requests, canceling requests, and response data. It is excellent for changing JSON data and provides client-side support to safeguard from the XSRF. It supports browsers like Safari, Mozilla Firefox, Google Chrome, Edge, and IE.

Form data:

Form data is the encoding type that transfers to the server for processing. Other encoding types can be utilized for non-file transfer like plain, text, application/x-www-form-urlencoded, and a lot more. React developer helps you in sending form data in react projects with Axios.

If form-data lets files to include in form data, plain or text propel data as plain text without encoding. It is applicable for debugging and not for production. Application/x-www-form-urlencoded instructs data as a query string. Encoding type can be included in HTML with enctype attribute.

Send form data in the Axios request:

Sending form data in the React app to the server is an important task among many developers. Axios is an important library for making HTTP requests quickly in React. You can understand the important process of sending form data in the react project using Axios.

While using Axios, developers easily make post requests and set the data they wish to send as a request body. If you carry out this process, you can utilize the Axios.post() method that acquires two arguments. It obtains arguments like server URL and data you need to send.

FormData object joins two fields with matching values. It makes HTTP requests to specific URLs with a FormData object. It uses them as a request body and sets the content-type header to multipart or form data.

Once the request is successful, the response can log into the console. If the request is abortive, the error response can log to the console. Using Axios in the project requires installing Axios first. You can install it with the proper command.

Launch react project:

Whether you have a project already, you don’t need to launch. If you don’t have any projects on your device, you can create them first.

You can open a terminal and run the required command.

npx create-react-app axios-form

Once project creation is over, you can go to the project directory.

Install axios:

To use Axios for post requests in the React project, you must install it properly. You can use the following command to install the Axios.

npm install axios

After successfully installing the Axios, you can carry out sending the form data in a project with the Axios post request.

Create form component:

When it comes to the React project, you must make a new component for form. You can name it and save it with .js

// src/Form.js

import React, { useState } from ‘react’;

import axios from ‘axios’;

function Form() {

const [formData, setFormData] = useState({

name: ‘’,

email: ‘’,

});

const handleChange = (e) => {

const { name, value } = e.target;

setFormData({ …formData, [name]: value });

};

const handleSubmit = async (e) => {

e.preventDefault();

try {

const response = await axios.post(‘YOUR_API_ENDPOINT’, formData);

console.log(‘Form data submitted successfully:’, response.data);

} catch (error) {

console.error(‘Error submitting form data:’, error);

}

};

return (

<label>

Name:

<input

type=”text”

name=”name”

value={formData.name}

onChange={handleChange}

</label>

<br />

<label>

Email:

<input

type=” email”

name=” email”

value={formData.email}

onChange={handleChange}

</label>

<br />

<button type=”submit”>Submit</button>

</form>

);

}

export default Form;

In this component, you can label the form with two input fields. You can utilize the useState hook to deal with form data. Axios is ideal for making the post request when the form submits successfully.

Import and apply form component:

After creating the form component, you need to import and apply the form component to the project.

// src/App.js

import React from ‘react’;

import Form from ‘./Form’;

function App() {

return (

<h1>React Form with Axios POST Request</h1>

</div>

);

}

export default App;

Replace your_api_endpoint:

In the form component, you can replace your_api_endpoint with the actual endpoint. It is easy to send the form data in a project and complete them easily

Run React application:

After the above step is over, it is time to run the React application with the following command like

npm start

React application is running and allows you to access it in the browser. You can fill out the form and click the submit button. You must view the form data that is sent to a specified API endpoint in the browser console. You can try the necessary steps for the form data sending in the project utilizing the Axios post request.

Conclusion:

Overall, the above details are useful to understand the process of sending the form data in react with Axios. With the help of a hire react expert, you can get the proper guidance and support to handle this process.

Experts assist you in integrating the form component with the server-side endpoint and dealing with the data effectively in a project. Axios makes a form data sending process in the react app development project. So, you can work with the skilled and knowledgeable react expert and obtain an ideal solution for challenges.

Redux

Redux is commonly used with React, but can be used with other UI framework or library as Redux is a state management library for JavaScript applications.

While working with React project, we deal with issues handling data, and there comes as savior, Redux. It is the best library for managing the state of an application. The state of the application is represented as a single object called the “store”, which is responsible for holding the entire state of the application. The store is immutable, which means that it cannot be changed directly.

To change the values in store, actions are dispatched to the store, which describe the changes that need to be made. A reducer function then takes the current state and the dispatched action as arguments, and returns a new state object that incorporates the changes described in the action.

Overall, Redux is a powerful library for managing application state in a predictable and centralized way, and helps to maintain state conveniently.

Creating a Full-Stack Web Application with React JS and Python Flask

React Native is a popular framework for building cross-platform mobile apps using JavaScript and React. It allows developers to create high-quality, performant mobile apps that work on both iOS and Android platforms. Python Django is a powerful web framework that can be used to build RESTful APIs that can be used by mobile apps.

In this article, we will walk through the process of building a React Native mobile app that communicates with a Python Django API.

Step 1: Set up the Django API

The first step is to create the Django API that our mobile app will communicate with. To do this, we'll need to create a new Django project and add a new app to it.

First, install Django by running the following command:

pip install django

Next, create a new Django project by running the following command:

django-admin startproject my project

This will create a new Django project called myproject. Next, create a new app called api by running the following command:

bash

cd myproject

python manage.py startapp api

This will create a new app called api inside the myproject project.

Next, open the settings.py file in the myproject folder and add the api app to the INSTALLED_APPS list:

css

INSTALLED_APPS = [ ... 'api',]

Now, open the urls.py file in the myproject folder and add the following code:

php

from django.urls import include, path

urlpatterns = [

path('api/', include('api.urls')),

]

This code creates a new URL pattern that maps to the api app.

Now, create a new file called urls.py in the api folder and add the following code:

python

from django.urls import path

from . import views

urlpatterns = [

path('hello/', views.hello),

]

This code creates a new URL pattern that maps to a new view called hello.

Finally, create a new file called views.py in the api folder and add the following code:

python

from django.http import JsonResponse

def hello(request):

return JsonResponse({'message': 'Hello from Django!'})

This code creates a new view that returns a JSON response with the message "Hello from Django!".

Now, start the Django development server by running the following command:

python manage.py runserver

This will start the development server on http://localhost:8000. If you navigate to http://localhost:8000/api/hello/ in your web browser, you should see the message "Hello from Django!". If you're looking for training in react native, then you can check out our react native course in Bangalore.

Step 2: Set up the React Native app

The next step is to set up the React Native app that will communicate with the Django API. To do this, we'll need to create a new React Native app using the expo-cli command line tool.

First, install the expo-cli tool by running the following command:

npm install -g expo-cli

Next, create a new React Native app by running the following command:

csharp

expo init myapp

This will create a new React Native app called myapp. Choose the "blank" template when prompted.

Next, install the axios library, which we'll use to make API requests, by running the following command:

Copy code

npm install axios

Finally, open the App.js file in the myapp folder and replace the existing code with the following:

python

Copy code

import React, { useEffect, useState } from 'react';

import {

import { StyleSheet, Text, View } from 'react-native';

import axios from 'axios';

export default function App() {

const [message, setMessage] = useState('');

useEffect(() => {

axios.get('http://localhost:8000/api/hello/')

.then(response => {

setMessage(response.data.message);

})

.catch(error => {

console.log(error);

});

}, []);

return (

<Text>{message}</Text>

</View>

);

}

const styles = StyleSheet.create({

container: {

flex: 1,

backgroundColor: '#fff',

alignItems: 'center',

justifyContent: 'center',

});

vbnet

Copy code

This code imports the necessary libraries, sets up a state variable called `message`, and makes an API request to the Django server using the `axios` library. The `useEffect` hook is used to make the API request when the component is mounted, and the response is used to update the `message` state variable. Finally, the `message` variable is displayed in the app. If you're looking for training in python, then you can check out our Python course in Bangalore.

Now, start the Expo development server by running the following command:

expo start

vb net

Copy code

This will start the Expo development server on `http://localhost:19002`. You can then run the app on your mobile device using the Expo app or on an emulator using the options provided on the development server page.

Conclusion

In this article, we walked through the process of building a React Native mobile app that communicates with a Python Django API. We created a new Django project and app, set up a new view to return a JSON response, and used the `axios` library to make API requests from our React Native app. By following these steps, you can build powerful mobile apps that communicate with a Python backend using the Django web framework.

In conclusion, building a React Native mobile app that communicates with a Python Django API is a powerful way to create cross-platform mobile applications. React Native offers a simple and efficient way to build mobile applications that work across multiple platforms, while Python and Django provide a flexible and robust backend that can handle complex data processing and business logic. By combining these two technologies, developers can create high-performance mobile apps with a powerful backend API. If you're looking for training in react JS, then you can check out our React JS course in Bangalore.

In this article, we covered the basics of setting up a Python Django API, creating a view to return JSON data, and building a React Native mobile app that communicates with the API. By following these steps, developers can build powerful, cross-platform mobile apps that can handle complex data and business logic. With the power of Python and Django on the backend and React Native on the frontend, the possibilities for mobile app development are endless.

Furthermore, they must know everything about CSS technologies like LESS, SASS, SCSS, and other pre-processors. Also, they should know technologies like CSS-in-JS and CSS frameworks like MaterialUI and Bootstrap) for styling React components.

ReactJS Workflows

ReactJS developers can easily manage projects and prioritize state management for their app performance optimization.

Moreover, they must know about popular libraries and structures of state management like Context API, React Native, Axios, React Router, Redux, MobX, etc. Their knowledge about new progress like React hooks can be an added benefit.

Sprint Planning

When hiring React developers, make sure that they are able to plan workflow and tasks to finish them on the said deadline. In other words, you must hire developers.

Workflows or tasks and finish them within the desired deadline. In short, you should hire React developers who are experts in sprint planning. They must be capable of dealing with task management tools to track and share the advancement of your project sprints.

Flexible Learning Curve

React features exceptional community support. It is one of the finest libraries for web development, which undergoes enormous changes and progresses every day. Therefore, the developers must be able to learn technology updates and changes when required.

Apart from these skills, you should consider interpersonal skills, such as acceptance of failure, efficient communication, teamwork, change management, creative thinking, and exposure to constructive feedback.

GSoC logs (June 5 –July 11)

July 5

DS Exam - 9:30AM.

Alternatives - If build not fixed by 8:30AM.

Reclone and commit all changes to new branch.

Get preview component done

Send the demo to mentors and then touch proto file.

Recloned. In the new clone, I made new changes. Everything works.

Turns out any write operation in the proto file is wrecking stuff. I navigated to the proto file in vscode and simply saved. This causes all the errors again.

Some import errors even though proto syntax are perfectly fine. Hmmm. protoc-gen-go: program not found or is not executable

I tried making the proto file executable with chmod +x. Still same issue. Hmmm.

That was stupid. Proto files aren’t supposed to be executable! -_- Where do I get these stupid ideas.

The error is actually referring to protoc-gen-go file. Saying that protoc-gen-go is not found or not executable. Not the proto file

I’m moving on to completing the preview component to send the demo before 7pm.

Preview component

Ipynb html. Axios get and render the htmlstring from response data in the iframe. Nop, v-html.

Serve html file from the http server for now.Wait, that's not possible.

Okay, maybe I should just use hello api for now. Since both request and response objects have string type properties.

This is embarrassing.

Okay, whatever.

Just fix this and look into it,

Okay, so I can’t represent an html string just like that as in python. With `` ..

Okay `` will do.

I’m starting to like golang. It looks ridiculous but also easy to understand? What’s going on?

July 6

Leads & Tries.

Try Samuel’s suggestion -

“Do you have protoc on your path?

sometimes VScode installs its own version of some tools on a custom $PATH - it could as well be that some extension is not properly initialized “

Interesting - I tried git diff on the proto file and this happens just by vscode saving it.

old mode 100644 new mode 100755

https://unix.stackexchange.com/a/450488

Changed back to 0644 and still the same issue in vscode.

Stupid girl, you just made the protofile executable yesterday and forgot to change it back. -_-

Read about makefile. Do as said. Annotations.proto forward slash path. ?? wtf?

Set gopath right! Permanently. !!! Okay, done. No need to set it everytime now. Hopefully.

Desperate attempts -

Edit proto file in atom. (Prepare to reclone ;_;)

Trying the same in vim ()

Text editor.

Okay, so nothing editor or ide specific.

Trying to change paths

Gopath was /home/anaswaratrajan/go .. changed it to /usr/local/go/bin

New error.

GO111MODULE=off go get -v github.com/golang/protobuf/protoc-gen-go github.com/golang/protobuf (download) package github.com/golang/protobuf/protoc-gen-go: mkdir /usr/local/go/bin/src: permission denied make: *** [Makefile:164: /usr/local/go/bin/bin/protoc-gen-go] Error 1

https://github.com/golang/go/issues/27187

sudo chown -R $USER: $HOME

Doesn’t feel right. But I just want this to get done. ;_;

The problem could be that I have multiple go distributions. After this is done, I need to clean this shit this weekend.

Okay, done chown. I own this shit!!! AAAa

Still permission denied! Shit. /usr/local/go not /usr/local/go/bin

Okay, changed it, but go env GOPATH echoing giving warning that GOROOT and GOPATH are same.

So from what I’ve read, gopath is the workspace, and goroot is the place where go is installed. Our makefile is trying to install and use the modules in GOPATH. Ie go dir in home. Okay, so my GOPATH was right before.

Final tries

* Follow the error trails. * Find out what exactly is happening when I save this file. 1. Okay, incase they don’t work out. Try to send the html string instead of “Hello ” string without changing proto file. 2. Since all ipynb files can have same css, try and send only the html elements. And do the css separately in frontend. 3. Stop Ctrl+Saving for no reason! Great, now I have to reclone ;_; and start over. 4. Okay, I was able to send a sample html string with the response. Without changin the proto file. 5. Here’s what I’m gonna do. 6. Send sample html string from hello service and render in the preview component. Pass the json string as name. Hahaha. Please, explain why you had to do the same. 7. I did exactly as above. I feel like an imposter now. Screw it. 8. Alright, I have my bigbang hyungs to support me. 9. I’m gonna embed python scripts by tonight. Update: that was overoptimistic. 10. So I have the nbconvert python script to generate basic html strings. 11. I should also remove those comments in the html. 12. So we’re using the less performance option since we don’t need much memory in the first place. Using python c api.

July 7

Learned one or 2 things about embedding python. https://github.com/ardanlabs/python-go/tree/master/py-in-mem

So I need python3.7. Bc go-python3 only supports python3.7. But there’s a workaround given. So I should try that

Tries

Go-python3 , python 3.8, workaround go get github.com/christian-korneck/go-python3 But a bunch of errors occurred.

Python 3.7 install

C-like usage from golang - low level stuff

https://blog.filippo.io/building-python-modules-with-go-1-5/ goodread. But that’s not what I need.

Let’s look at Ardan’s lab way.

https://www.ardanlabs.com/blog/2020/09/using-python-memory.html

This is a bit more challenging but more understandable.

This is the way.

I should start with this right after fixing the make issue.

Back to build fixing

Do as samuel suggested. - no luck.

What I know so far. The issue is rooted with golang or protobuf or sth related. Since the issue is there for all the text editors including vim.

I found sth weird -Which go => /usr/local/go/bin/goWhen it gives /usr/local/bin/go to this dude https://stackoverflow.com/a/67419012/13580063

Okay, not so weird.

The interview went okay. They use photogenometry to generate those 3d maps out of their drone imagery. Their products sound interesting. They need frontend engineers to work on their platform. The interface currently looks almost like google maps. But 3d. Cool. I actually used the phrase.. “..I’m still in my 20s.. Don’t wanna die.. So can’t move to Bengalore anytime soon”

Not photogenometry. Photogrammetry. Also used by some old mars rovers. Wait, no it was sth else. I remember Shreyansh mentioning it. I wonder what all they’re planning for the dragonfly.

Focus. It’s been some days with this issue, you should get help.

Asked around a bunch of people on discord. No luck.

July 8

Let’s dig in.

Tries

1. Reinstall golang#2. https://stackoverflow.com/a/67419012/13580063 ? Nop.#3. See protoc installation details. Read more about protoc, protobugs

https://developers.google.com/protocol-buffers/docs/reference/go-generated#4. Read more about golang ecosystem - 30m and see if **which go **path is weird. 3. Also found this https://github.com/owncloud/ocis-hello/issues/62 Nop. 4. Let’s go with the error trails. 5. Wait, did I just graduate today. Oh no. Just like that. 6. Okay, grind.

Make generate is giving this.

GO111MODULE=off go get -v github.com/golang/protobuf/protoc-gen-go GO111MODULE=on go get -v github.com/micro/protoc-gen-micro/v2 GO111MODULE=off go get -v github.com/webhippie/protoc-gen-microweb GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2 protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --go_out=pkg/proto/v0 hello.proto protoc-gen-go: program not found or is not executable Please specify a program using absolute path or make sure the program is available in your PATH system variable --go_out: protoc-gen-go: Plugin failed with status code 1. make: *** [Makefile:176: pkg/proto/v0/hello.pb.go] Error 1

Then I try echo $GOPATH and It’s empty. go env GOPATH is right

So I set the GOPATH

export GOROOT=/usr/local/go export GOPATH=$HOME/go export GOBIN=$GOPATH/bin export PATH=$PATH:$GOROOT:$GOPATH:$GOBIN

Now, I get this

GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2 protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --go_out=pkg/proto/v0 hello.proto protoc-gen-go: invalid Go import path "proto" for "hello.proto" The import path must contain at least one forward slash ('/') character. See https://developers.google.com/protocol-buffers/docs/reference/go-generated#package for more information. --go_out: protoc-gen-go: Plugin failed with status code 1. make: *** [Makefile:176: pkg/proto/v0/hello.pb.go] Error 1

Did this https://github.com/techschool/pcbook-go/issues/3#issuecomment-821860413 and the one below and started getting this```

GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2 protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --go_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --micro_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --microweb_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --swagger_out=logtostderr=true:pkg/proto/v0 hello.proto protoc-gen-swagger: program not found or is not executable Please specify a program using absolute path or make sure the program is available in your PATH system variable --swagger_out: protoc-gen-swagger: Plugin failed with status code 1. make: *** [Makefile:194: pkg/proto/v0/hello.swagger.json] Error 1

July 9

Now trying to read this from the error https://developers.google.com/protocol-buffers/docs/reference/go-generated#package

option go_package = "github.com/anaswaratrajan/ocis-jupyter/pkg/proto/v0;proto";

Tried this, new issue

GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2 protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --go_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --micro_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --microweb_out=pkg/proto/v0 hello.proto protoc \ -I=third_party/ \ -I=pkg/proto/v0/ \ --swagger_out=logtostderr=true:pkg/proto/v0 hello.proto protoc-gen-swagger: program not found or is not executable Please specify a program using absolute path or make sure the program is available in your PATH system variable --swagger_out: protoc-gen-swagger: Plugin failed with status code 1. make: *** [Makefile:194: pkg/proto/v0/hello.swagger.json] Error 1

Okay, so proto-gen-swagger is not in gopath as expected. So this isn’t working.

$(GOPATH)/bin/protoc-gen-swagger: GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2

Instead of protoc-gen-swagger, there’s protoc-gen-openapiv2. So I replace protoc-gen-swagger from last line in the makefile to the executable in the path.https://grpc-ecosystem.github.io/grpc-gateway/docs/development/grpc-gateway_v2_migration_guide/

Turns out they rename protoc-gen-swagger to protoc-gen-openapiv2

Oooo.. I just found out, option go_package = "github.com/anaswaratrajan/ocis-jupyter/pkg/proto/v0;proto";

This just made things weird. New directory github.com/anaswa... inside proto/v0/

So go_package path is messed up.

Just replacing swagger binary names in makefile lets you generate the proto files at github.com/anas… dir

Let’s try fixing the go_package path and then try to generate the annotations.proto and the openapiv2 files (the grpc gateway files)

Wait, you don't generate them.

option go_package = "./;proto";

This is the right way.

So yea, I’m able to generate the go-code now. But make is still failing and I should sleep now.

July 11

Ownclouders already tried to work on it. But for some reason, they didn’t make the changes. Why?

Look into this. Why they didn’t continue doing this.

https://github.com/owncloud/ocis-hello/issues/91

So what exactly is micro-web service? This protoc-gen-microweb is a protoc generator for micro web services. And it's generating this hello.pb.web.go

What just happened? New error/ Make generate gives

`GO111MODULE=off go get -v github.com/grpc-ecosystem/grpc-gateway/protoc-gen-openapiv2 go generate github.com/anaswaratrajan/ocis-jupyter/pkg/assets panic: No files found goroutine 1 [running]: main.main() /home/anaswaratrajan/go/pkg/mod/github.com/!unno!ted/fileb0x[@v1](https://tmblr.co/mkYynE1Axr-EFCSIQIAtheA).1.4/main.go:101 +0x2765 exit status 2 pkg/assets/assets.go:12: running "go": exit status 1 make: *** [Makefile:83: generate] Error 1
