How to set HTTP header for $http.GET request in angularjs?

The AngularJs code sample as given below

//This is the global

var baseURL = "http://localhost:8080/";

var emailId = window.utility.user.EmailID

var userID = window.utility.user.UserID;

var userLocationID = window.utility.user.UserLocationID;

var authInfo = {

    Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==',

    UserID: userID,

    UserLocationID: userLocationID

};

//END

var app = angular.module('authApp', []);

//This is the angular services

app.service("myAuthServices", function ($http) {

    this.getUsers = function (url) {

        return $http({

            method: 'GET',

            url: baseURL + url,

            headers: authInfo

        });

    };

});

//This is the angular controller.

app.controller('baseController', function ($scope, myAuthServices) {

    //This is default values.

    $scope.users = null;

    var apiURL = "api/Users_API/GetUsers/";

    //Call get user services.

    myAuthServices.getUsers(apiURL).then(function (resp) {

        if (resp !== undefined && resp !== null) {

            if (resp.data !== undefined && resp.data !== null) {

                $scope.users = resp.data;

            }

        }

            UserID = Convert.ToInt32(Request.Headers.GetValues("UserID").First());

        if (Request.Headers.Contains("UserLocationID"))

            UserLocationID = Convert.ToInt32(Request.Headers.GetValues("UserLocationID").First());

        var result = _repoUser.GetCompUsers(EmailID, UserID, UserLocationID);

        return Json(result);

    }
