How to send a token with an AJAX request from jQuery

Question

I use express-jwt and create my token via jQuery and save it in my localStorage with:

$.ajax({   url: "http://localhost:8080/login",   type: 'POST',   data: formData,   error : function(err) {     console.log('Error!', err)   },   success: function(data) {     console.log('Success!')     localStorage.setItem('token', data.id_token);   } }); 

I have a protected route in my backend like:

app.get('/upload',jwt({secret: config.secret}), function(req, res) {   res.sendFile(path.join(__dirname + '/upload.html')); }); 

How can I send the token from localStorage with the request header?

Answer 1

You can set the headers in a $.ajax request:

$.ajax({   url: "http://localhost:8080/login",   type: 'GET',   // Fetch the stored token from localStorage and set in the header   headers: {"Authorization": localStorage.getItem('token')} });
