react-native fetch and basic authentication

Question

I tried to use fetch with this syntax:

fetch(\"https://user:password@url\", {
   ...
}).then((response) => {
   ...
}).done();

The same url

Answer 1

I found that this format https://user:password@url works well in CURL and node but not with fetch.

I had to use base-64 npm module and pass through a Headers object.

// https://www.npmjs.com/package/base-64
const base64 = require('base-64');

...

var headers = new Headers();
headers.append("Authorization", "Basic " + base64.encode("user:password"));

fetch("https://url", {
    headers: headers
  })
  .then((response) => { ... })
  .done();
