Sending the bearer token with axios

Sending the Bearer Token with Axios: A Complete Guide 🚀

Are you having trouble sending the Authorization header with your requests using Axios in your React app? You've come to the right place! In this guide, we'll address the common issue of the Authorization header not being sent and provide you with easy solutions. Let's dive in! 💪

The Problem: Unable to Send the Authorization Header 🚫

You're using Axios, a popular library for making HTTP requests in JavaScript, but you're facing an issue where the Authorization header is not being sent along with your requests. This can be frustrating, especially if you're working on an app that requires authentication.

Here's an example of the code you're using:

tokenPayload() {
  let config = {
    headers: {
      'Authorization': 'Bearer ' + validToken()
    }
  }
  Axios.post( 
      'http://localhost:8000/api/v1/get_token_payloads',
      config
    )
    .then( ( response ) => {
      console.log( response )
    } )
    .catch()
}

You're setting the Authorization header by concatenating the token obtained from your browser storage using the validToken() method. However, the requests are consistently resulting in a 500 error response, with the message "The token could not be parsed from the request" from the backend.

The Solution: Axios Interceptors and Token Parsing ✅

To solve this issue, we need to modify our code and make use of Axios interceptors. Interceptors allow us to inspect and modify HTTP requests and responses. In this case, we'll use an interceptor to ensure that the Authorization header is included with every request sent using Axios.

Here's an updated version of the code that includes the required interceptor:

import axios from 'axios';

// Create an instance of Axios
const api = axios.create({
  baseURL: 'http://localhost:8000/api/v1',
});

// Add an interceptor to include the Authorization header
api.interceptors.request.use((config) => {
  const token = validToken(); // Obtain the token from browser storage using the validToken() method
  config.headers.Authorization = `Bearer ${token}`;
  return config;
});

// Perform the request using the modified Axios instance
api.post('/get_token_payloads')
  .then((response) => {
    console.log(response);
  })
  .catch((error) => {
    console.error(error);
  });

In this updated code, we create an instance of Axios called api and add an interceptor to it using api.interceptors.request.use(). Inside the interceptor function, we obtain the token using the validToken() method, and then set the Authorization header with the necessary Bearer prefix.

Now, when you make a request using the api instance, the Authorization header will automatically be included, ensuring that the token is sent with each request.

A Note on Other Modules with React 📚

While Axios is a popular choice for making HTTP requests in React, there are other modules available that you might consider for your project. Some popular alternatives include fetch and superagent. Each module has its pros and cons, so it's a good idea to explore their documentation and decide which one best fits your needs.
