ExpressJS + Axios : can't send header authorization - express

Question

I don't understand why express js cannot read my header.
I use vuejs + axios for send data.
I use a module for intercept request ans response for send token.
In axios module :
axios.interceptors.request.use((req) => {
req.headers.authorization = `Bearer: ${MYTOKEN}`;
return req;
});
In my server, i use nodesJS + Express with middleware :
const router = express.Router();
router.use(function timeLog(req, res, next) {
console.log(req.headers.authorization); // undefined :(
})
So req.headers do not contains key 'authorization' and console.log(req.headers.authorization); return to me 'UNDEFINED'.
I've try to put req.header.BLABLABLA. I find it but not as key.
I really don't understand.
Exemple of return with authorization :
{ host: 'localhost:5000',
connection: 'keep-alive',
'access-control-request-method': 'POST',
origin: 'http://localhost:8080',
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36',
'access-control-request-headers': 'authorization,content-type',
accept: '*/*',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'fr-FR,fr;q=0.9,en;q=0.8,en-US;q=0.7,ru;q=0.6'
}

Answer 1

try this
axios.interceptors.request.use((req) => {
// req here, it's axios config, not express req'. req.headers.Authorization = Bearer: ${MYTOKEN}`;
return req;
});
Authorization => start with A Capital

You're using Axios in the wrong way.
You're trying to log headers of the Express Request, not headers of the Axios.
// server/index.js
router.use(function timeLog(req, res, next) {
console.log(req.headers.authorization); // of course this is will undefined
})
If you're doing like so, you'll get your authorization headers...
// server/index.js
import axios from 'axios'
axios.interceptors.request.use((req) => {
// `req` here, it's axios config, not express `req'.
req.headers.authorization = `Bearer: ${MYTOKEN}`;
return req;
});
router.use(function timeLog(req, res, next) {
console.log(axios.headers.authorization); // here we are
})
