I make web application with React, Express, MongoDB.

And, I want to pass jwt token with header.

But, I pass it, get 401 error (Unauthorized).

In login actions.js :

export function login(username, password) {
return function(dispatch) {
  .post(`${API_URL}/auth/login`, { username, password })
  .then(res => {
    dispatch(loginSuccess(, username));
    const token =;
    axios.defaults.headers.common["Authorization"] = token;
  .catch(err => {
    if (err.response.status === 401) {

And, In my post.js in server :

getToken = function(headers) {
  if (headers && headers.authorization) {
    var parted = headers.authorization.split(" ");
      if (parted.length === 2) {
       return parted[1];
      } else {
       return null;
    } else {
     return null;
// Save Post"/", passport.authenticate("jwt", { session: false }), 
  ) {
 var token = getToken(req.headers);
 if (token) {
   Post.create(req.body, function(err, post) {
     if (err) return next(err);
   } else {
    return res.status(403).send({ success: false, msg: "Unauthorized." });

How I do fix it? + Login is success

First of all when you login and send username and password to backend then in response you get token_id. now try to token store in session_storage and redirect to your desire page. now you take token_id in your desire page and store one variable as like..

let user = JSON.parse(sessionStorage.getItem('data'));
const token =;

now you have token and pass in the header and get data in response

const api = `your api here`
axios.get(api, { headers: {"Authorization" : `Bearer ${token}`} })
        .then(res => {
            items:,  /*set response data in items array*/
            isLoaded : true,
            redirectToReferrer: false

note : you should set blank items array in initial setState as like

            isLoaded: false,

How to send the authorization header using Axios, The easiest way for me was to use basic authentication. I was using Axios, so I set the Authorization header to the POST request in this way:. One of the relevant headers that the host can set in a preflight response is Access-Control-Allow-Headers. If any of the headers you want to send were not listed in either the spec's list of whitelisted headers or the server's preflight response, then the browser will refuse to send your request.

This is example for create axios instance with API Base URL and JWT_TOKEN globally and access it for different API calls

step 1 : create static instance for axios

static axiosInstance =  axios.create({
    baseURL: "BASE_API_URL",
    timeout: 5000,
    headers: {
      'Authorization': "JWT_TOKEN",
      'Content-Type': 'application/json'

this is the second setep access axiosInstance already create and use it with dynamic REST API calls

step 2 : access static instance and bind API_URL to base URL

export const x = (data) => dispatch => {'API_URL',
        .then(function (response) {

        .catch(function (error) {


API URL = BASE_API_URL + API_URL and single JWT_TOKEN for all and this very clean , clear and working.
