How to set authorization header on $http request in angularjs with MVC5?

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;

            }

        }

    });

});

MVC5 part code sample as given below

[RoutePrefix("api/Users_API")]

public class Users_APIController : ApiController

{

    UsersRepository _repoUser = new UsersRepository();

    [Route("GetUsers")]

    public IHttpActionResult GetUsers()

    {

        long UserID = 0, UserLocationID = 0; string EmailID = null;

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

            EmailID = Request.Headers.GetValues("Authorization").First();

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

            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);

    }

}

inheritance in JavaScript

How to achieve inheritance in JavaScript?

In the JavaScript, we can implement the inheritance using the some alternative ways and we cannot define a class keyword but we create a constructor function and using new keyword achieve it.  

The some alternative ways as given  below.

1. Pseudo classical inheritance
2. Prototype inheritance

Pseudo classical inheritance is the most popular way. In this way, create a constructor function using the new operator and add the members function with the help for constructor function prototype.

The prototype based programming is a technique of object oriented programming. In this mechanism we can reuse the exiting objects as prototypes. The prototype inheritance also know as prototypal, 

classless or instance based inheritances.

The Inheritance example for prototype based as given below

  // Create a helper function.

    if (typeof Object.create !== 'function') {

        Object.create = function (obj) {

            function fun() { };

            fun.prototype = obj;

            return new fun();

        };

    }

    //This is a parent class.

    var parent = {

        sayHi: function () {

            alert('Hi, I am parent!');

        },

        sayHiToWalk: function () {

            alert('Hi, I am parent! and going to walk!');

        }

    };

    //This is child class and the parent class is inherited in the child class.

    var child = Object.create(parent);

    child.sayHi = function () {

        alert('Hi, I am a child!');

    };

<button type="submit" onclick="child.sayHi()"> click to oops</button>

The output is : Hi, I am a child!
