Sending the bearer token with axios - reactjs

Question

In my react app i am using axios to perform the REST api requests.
But it's unable to send the Authorization header with the request.
Here is my code:
tokenPayload() {
let config = {
headers: {
'Authorization': 'Bearer ' + validToken()
}
}
Axios.post(
'http://localhost:8000/api/v1/get_token_payloads',
config
)
.then( ( response ) => {
console.log( response )
} )
.catch()
}
Here the validToken() method would simply return the token from browser storage.
All requests are having a 500 error response saying that
The token could not be parsed from the request
from the back-end.
How to send the authorization header with each requests? Would you recommend any other module with react?

Answer 1

const config = {
headers: { Authorization: `Bearer ${token}` }
};
const bodyParameters = {
key: "value"
};
Axios.post(
'http://localhost:8000/api/v1/get_token_payloads',
bodyParameters,
config
).then(console.log).catch(console.log);
The first parameter is the URL.
The second is the JSON body that will be sent along your request.
The third parameter are the headers (among other things). Which is JSON as well.

Answer 2

Here is a unique way of setting Authorization token in axios. Setting configuration to every axios call is not a good idea and you can change the default Authorization token by:
import axios from 'axios';
axios.defaults.baseURL = 'http://localhost:1010/'
axios.defaults.headers.common = {'Authorization': `bearer ${token}`}
export default axios;
Some API require bearer to be written as Bearer, so you can do:
axios.defaults.headers.common = {'Authorization': `Bearer ${token}`}
Now you don't need to set configuration to every API call. Now Authorization token is set to every axios call.

Answer 3

You can create config once and use it everywhere.
const instance = axios.create({
baseURL: 'https://example.com/api/',
timeout: 1000,
headers: {'Authorization': 'Bearer '+token}
});
instance.get('/path')
.then(response => {
return response.data;
})

Answer 4

The second parameter of axios.post is data (not config). config is the third parameter. Please see this for details: https://github.com/mzabriskie/axios#axiosposturl-data-config

Answer 5

By using Axios interceptor:
const service = axios.create({
timeout: 20000 // request timeout
});
// request interceptor
service.interceptors.request.use(
config => {
// Do something before request is sent
config.headers["Authorization"] = "bearer " + getToken();
return config;
},
error => {
Promise.reject(error);
}
);

Answer 6

If you want to some data after passing token in header so that try this code
const api = 'your api';
const token = JSON.parse(sessionStorage.getItem('data'));
const token = user.data.id; /*take only token and save in token variable*/
axios.get(api , { headers: {"Authorization" : `Bearer ${token}`} })
.then(res => {
console.log(res.data);
.catch((error) => {
console.log(error)
});

Answer 7

Just in case someone faced the same issue.
The issue here is when passing the header without data, the header's configuration will be in the payload data, So I needed to pass null instead of data then set the header's configuration.
const config = {
headers: {
"Content-type": "application/json",
"Authorization": `Bearer ${Cookies.get("jwt")}`,
},
};
axios.get(`${BASE_URL}`, null, config)

Answer 8

This works and I need to set the token only once in my app.js:
axios.defaults.headers.common = {
'Authorization': 'Bearer ' + token
};
Then I can make requests in my components without setting the header again.
"axios": "^0.19.0",

Answer 9

I use a separate file to init axios instance and at the same time, I add intercepters to it. Then in each call, the intercepter will add the token to the request header for me.
import axios from 'axios';
import { getToken } from '../hooks/useToken';
const axiosInstance = axios.create({
baseURL: process.env.REACT_APP_BASE_URL,
});
axiosInstance.interceptors.request.use(
(config) => {
const token = getToken();
const auth = token ? `Bearer ${token}` : '';
config.headers.common['Authorization'] = auth;
return config;
},
(error) => Promise.reject(error),
);
export default axiosInstance;
Here is how I use it in the service file.
import { CancelToken } from 'axios';
import { ToolResponse } from '../types/Tool';
import axiosInstance from './axios';
export const getTools = (cancelToken: CancelToken): Promise<ToolResponse> => {
return axiosInstance.get('tool', { cancelToken });
};

// usetoken is hook i mad it
export const useToken = () => {
return JSON.parse(localStorage.getItem('user')).token || ''
}
const token = useToken();
const axiosIntance = axios.create({
baseURL: api,
headers: {
'Authorization':`Bearer ${token}`
}
});
axiosIntance.interceptors.request.use((req) => {
if(token){
req.headers.Authorization = `Bearer ${token}`;
}
return req;
})

Answer 11

If you are sending a post request with empty data remember to always set the second parameter to either empty object or empty string just as in the example below. e.g: axios.post('your-end-point-url-here', '', config)
if you don't set it axios will assume that whatever you are passing as the second parameter is a formData
const config = {
headers: { Authorization: `Bearer ${storage.getToken()}` }
};
axios
.post('http://localhost:8000/api/v1/get_token_payloads', {}, config)
.then(({ data: isData }) => {
console.log(isData);
})
.catch(error => {
console.log(error);
});

Answer 12

You must mention the 2nd parameter body for the post request even if it is empty, try this :
tokenPayload() {
let config = {
headers: {
'Authorization': 'Bearer ' + validToken()
}
}
Axios.post(
'http://localhost:8000/api/v1/get_token_payloads',
// empty body
{},
config
)
.then( (response) => {
console.log(response)
} )
.catch()
}

Answer 13

You can try configuring the header like this:
const headers = {"Content-Type": "text/plain", "x-access-token": token}

Answer 14

You can use interceptors in axios:
axios.interceptors.request.use(function (config) {
// Do something before request is sent
return config;
}, function (error) {
// Do something with request error
return Promise.reject(error);
});
More on that you can find here: https://axios-http.com/docs/interceptors

Answer 15

there are a lot of good solution but I use this
let token=localStorage.getItem("token");
var myAxios=axios.create({
baseURL: 'https://localhost:5001',
timeout: 700,
headers: {'Authorization': `bearer ${token}`}
});
export default myAxios;
then i import myaxios to my file and
myAxios.get("sth")

Answer 16

axios by itself comes with two useful "methods" the interceptors that are none but middlewares between the request and the response. so if on each request you want to send the token. Use the interceptor.request.
I made apackage that helps you out:
$ npm i axios-es6-class
Now you can use axios as class
export class UserApi extends Api {
constructor (config) {
super(config);
// this middleware is been called right before the http request is made.
this.interceptors.request.use(param => {
return {
...param,
defaults: {
headers: {
...param.headers,
"Authorization": `Bearer ${this.getToken()}`
},
}
}
});
this.login = this.login.bind(this);
this.getSome = this.getSome.bind(this);
}
login (credentials) {
return this.post("/end-point", {...credentials})
.then(response => this.setToken(response.data))
.catch(this.error);
}
getSome () {
return this.get("/end-point")
.then(this.success)
.catch(this.error);
}
}
I mean the implementation of the middleware depends on you, or if you prefer to create your own axios-es6-class
