User.Identity.GetUserId() and RequestContext.Principal.Identity.GetUserId() returns NULL in WEB API controller. Used Token based Aunthentication

Question

I have used Tokens to secure my Web API website, and consumed this API from an AngularJS client application.

With this I am able to login with token based authentication. My issue is that I am not able to get the UserId in Web API controller.

Both User.Identity.GetUserId() and RequestContext.Principal.Identity.GetUserId() are returning null.

How to get the UserId in an ApiController?

User.Identity.GetUserId() should return the current logged in user's UserID. Are you trying with a logged in user (passing Bearer AuthToken) in the Authorization header while calling WebAPI? — Krishnandu Sarkar, Jul 11 '16 at 06:45

If you already have a bearer token, set the Authorization header in javascript.

var token = sessionStorage.getItem(tokenKey);
var headers = {};
if (token) {
    headers.Authorization = 'Bearer ' + token;
}

Then you should include headers in your ajax request:

 $.ajax({
        type: 'GET',
        url: 'api/values/1',
        headers: headers
    }).done(function (data) {
        self.result(data);
    }).fail(showError);

Finally in your controller you can get user id by:

var userId = RequestContext.Principal.Identity.GetUserId();
