我遇到了一個CORS問題,當我使用Internet Explorer時完全正常工作,但無法與Google Chrome一起使用。MVC CORS適用於IE瀏覽器,但不適用於Chrome瀏覽器
我在Visual Studio 2013中有兩個獨立的項目:PROJECT 1在端口1044上,它只是一個空的項目,包含一個HTML頁面,其中包含一個Button,它使用AngularJS撥打ACTION GetCustomer
,位於PROJECT 2內的端口1042然後ACTION將JSON數據返回到PROJECT 1.
在IE中單擊按鈕並將數據返回到HTML文本框並顯示「ShivDataFromServer」時,跨域調用正常工作。但在Chrome中也不會發生這種情況。
PROJECT 1上端口1044:

<input type="button" id="btn1" value="Get data from Server" ng-click="GetData()" />
</div>
</div>
</body>
</html>
CustomerViewModel.js:
function MyController($scope, $http) {
$scope.Customer = { "Name": "ShivHardCodedData", "Amount": "1000" };
$scope.CustomerView = { "Color": "" };
//BELOW IS TRANSFORMATION LOGIC! Depending on Amount it will be GREEN or RED meaning "danger".
$scope.$watch("Customer.Amount", function() {
if ($scope.Customer.Amount < 1000) {
$scope.CustomerView.Color = "Green";
} else {
$scope.CustomerView.Color = "Red";
}
}
);
$scope.GetData = function() {
//BELOW WORKS!!
$http({ method: "GET", url: "http://localhost:1042/Customer/GetCustomer" })
.success(function (data, status, headers, config) { $scope.Customer = data; })
.error(function (data, status, headers, config) { });
} //END OF "GetData() function"
}
PROJECT 2這是一個MVC項目在端口1042:個
CustomerController.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using P10JsonJQuery_httpService.Models;
namespace P10JsonJQuery_httpService.Controllers
{
public class CustomerController : Controller
{
[ImAllowingCors]
public ActionResult GetCustomer()
{
Customer objCustomer=new Customer();
objCustomer.Name = "ShivDataFromServer";
objCustomer.Amount = 1000;
return Json(objCustomer, JsonRequestBehavior.AllowGet);
}
}
//CORS (Cross Origin Resource Sharing). I've made up name "ImAllowingCors" but ending "Attribute" is C# KEYWORD
public class ImAllowingCorsAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
//This means ALLOW any calls from a Cross-domain (i.e. allow calls from different server)
filterContext.RequestContext.HttpContext.Response.AddHeader("Access-Control-Allow-Origin", "*");
base.OnActionExecuting(filterContext);
}
}
}
不知道爲什麼它仍然沒有擊中我的行動,即使經過上述更改。 – maf
