Dealing with 401 Errors: Navigating Redirects using Vue.js and

Question

Dealing with 401 Errors: Navigating Redirects using Vue.js and

Currently, I am utilizing Vue.js along with axios in an attempt to create a generic API object as shown below:

import router from './router'
import auth from './auth'
const axios = require('axios')

export const API = axios.create({
  baseURL: `https://my-api.com/`,
  headers: {
    Authorization: auth.getToken()
  }
})

API.interceptors.response.use(null, function (error) {
  if (error.response.status === 401) {
    console.log('Failed to login')
    router.push('/Login')
  }
  return Promise.reject(error)
})

The goal is to automatically redirect users to the Login screen within my single-page application whenever a 401 error code is received. However, despite receiving the console.log message of Failed to login, there is no redirection taking place and no errors are detected in Chrome's Developer Tools.

If you need to handle errors in your axios post request, here's a simple example:

axios.post("api/endpoint", data)
  .catch(function(error) {
    if (error.response && error.response.status === 401) {
      window.location.href = "login";
    } else {
      // Handle the error in the way that fits your application
    }
  });

If you need to integrate an httpClient.js file into your project, you can utilize the following code snippet:

import axios from 'axios';
import {
  authHeader
}
from '../helper'

const baseUrl = 'http://localhost:8811/api/';//local-test
const Api_Path = `${baseUrl}/`;

const httpClient = axios.create({
  baseURL: Api_Path,
  headers: {
    //Authorization: 'Bearer {token}',
    //timeout: 1000, // indicates, 1000ms ie. 1 second
    "Content-Type": "application/json",

  }
})
const authInterceptor = (config) => {
  config.headers['Authorization'] = authHeader();
  return config;
}
const errorInterceptor = error => {


// check if it's a server error
  if (!error.response) {
    //notify.warn('Network/Server error');
    console.error('**Network/Server error');
    console.log(error.response);
    return Promise.reject(error);
  }

  // all the other error responses
  switch (error.response.status) {
    case 400:
      console.error(error.response.status, error.message);
      //notify.warn('Nothing to display', 'Data Not Found');
      break;

    case 401: // authentication error, logout the user
      //notify.warn('Please login again', 'Session Expired');
      console.error(error.response.status, error.message);
      localStorage.removeItem('token');
      localStorage.removeItem('user');
      //router.push('/auth');
      break;

default:
  console.error(error.response.status, error.message);
  //notify.error('Server Error');



 }
  return Promise.reject(error);
}
httpClient.interceptors.request.use(authInterceptor);
httpClient.interceptors.response.use(responseInterceptor, errorInterceptor);

export default httpClient;
