title: How to set authorization headers with nodejs and express
body: <p>I am setting up a site with nodejs, express, mongoose and swig template following this tutorial :
  <a href="https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens" rel="nofollow">Authenticate a Node.js API with JSON Web Tokens</a></p>
  
  <p>In this tutorial the author uses Postman to set the token in the header.
  I have googled for days to find out how I can set the jwt token in the header of my site, but it is not working for me.</p>
