    Hi.

     

    If you're using XMLHttpRequest, you could so something like this:

     

    var xhttp = new XMLHttpRequest();

xhttp.onreadystatechange = function()
{
    if (this.readyState == 4 && this.status == 200)
		console.log("request complete");
};

xhttp.setRequestHeader('Authorization', 'Bearer ' + localStorage.getItem("jwtoken"));
xhttp.open("GET", "filename", true);
xhttp.send();

      Hello Joao, you already help me (i changed to a new account but in the past already asked and you answered) anyway thanks!

       i am trying to use something like this :

       

      var reqCurrent = new XMLHttpRequest();
reqCurrent.open("GET", "URL", true);

reqCurrent.setRequestHeader('Authorization', 'Bearer ' + 'Token');
reqCurrent.addEventListener("load", currentLoader);
reqCurrent.send();

       

      but i getting "CORS Policy error" , this is from server configuration or my fault?

      Thanks a lot,

      Awesome! Really good to know!

       

      Have you tried something like this:

      xhttp.setRequestHeader("Access-Control-Allow-Origin", "*");

       

      If that doesn't work, then you probably have to configure the server.
