I want to write a simple basic authentication with fetch, but I keep getting a 401 error. It would be awesome if someone tells me what's wrong with the code:
let base64 = require('base-64');
let url = 'http://eu.httpbin.org/basic-auth/user/passwd';
let username = 'user';
let password = 'passwd';
let headers = new Headers();
//headers.append('Content-Type', 'text/json');
headers.append('Authorization', 'Basic' + base64.encode(username + ":" + password));
fetch(url, {method:'GET',
headers: headers,
//credentials: 'user:passwd'
})
.then(response => response.json())
.then(json => console.log(json));
//.done();
You are missing a space between Basic and the encoded username and password.
headers.set('Authorization', 'Basic ' + base64.encode(username + ":" + password));
A solution without dependencies.
Node
headers.set('Authorization', 'Basic ' + Buffer.from(username + ":" + password).toString('base64'));
Browser
headers.set('Authorization', 'Basic ' + btoa(username + ":" + password));
In pure JavaScript you can also use btoa instead of base64.encode():
headers.set('Authorization', 'Basic ' + btoa(username + ":" + password));
Note that this will only work with ASCII characters.
If you have to handle different encodings, see the linked btoa documentation.
