Access to XMLHttpRequest has been blocked by CORS policy

Question

Hi,

 

I have created Web Api and trying to access it from MVC application,

 

Now Web Api is having below method

 

[HttpGet]

[Route("api/UserMasterApi/GetUser")]

[EnableCors("*", "*", "*")]

public HttpResponseMessage GetUser(string userName, string userPassword)

{

HttpResponseMessage responseMsg = new HttpResponseMessage();

var user = new UserMastersDBRepository().GetUser(

new UsersMasterBusinessModel()

{

UserName = userName,

UserPassword = userPassword

}

);

if (user == null)

{

return

responseMsg =

Request.CreateResponse(HttpStatusCode.OK,

new

{

Status = "Fail",

Message = "Get Api",

Body = new { Username = "" }

});

}

else

{

return

responseMsg =

Request.CreateResponse(HttpStatusCode.OK,

new

{

Status = "SUCESS",

Message = "Get Api",

Body = new { Username = user }

});

}

}

 

Now when I am trying to access this using ajax call

 

$.ajax({

//url: 'http://localhost:64995/api/UserMasterApi/',

url: 'http://localhost:64995/api/UserMasterApi/GetUser/',

contentType: 'application/json',

// dataType: 'json',

accepts: "application/json; charset=utf-8",

type: 'POST',

data: JSON.stringify({ userName: userName, userPassword: password }),

success: function (data) {

debugger

if (data.Success) {

window.location.href = loc + "/Home";

}

});

 

And in WebApiConfig

 

public static void Register(HttpConfiguration config)

{

config.EnableCors();

// Web API configuration and services

// Web API routes

config.MapHttpAttributeRoutes();

config.Routes.MapHttpRoute(

name: "DefaultApi",

routeTemplate: "api/{controller}/{id}",

defaults: new { id = RouteParameter.Optional }

);

}

 

Getting error for CORS.

Please help.
