ASP.NET MVC 2 - jquery ajax 響應失敗

我不明白這個錯誤，不要在“JsonResult Test（）”中產生錯誤，我正在做其他項目作為ASP.NET MVC

謝謝

錯誤：

System.InvalidOperationException: This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.

C＃

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace Tesis.Controllers
{
   public class AnalysisSourceDataController : Controller
   {
       //
       // GET: /AnalysisSourceData/

       public ActionResult Index()
       {
           return View();
       }

       public JsonResult Test()
       {
           return Json(new { mymsg = "my msg" });
       }
   }
}

javascript

<script type="text/javascript">
   $(function() {
       $.getJSON("/AnalysisSourceData/Test", function(data) {
           alert(data.mymsg);
       });
   });
</script>

你不明白什麼？這個錯誤幾乎不能更具描述性。這是防止JSON 劫持的安全功能，您可以像這樣禁用它..

return Json(new { mymsg = "my msg" }, JsonRequestBehavior.AllowGet);

但你應該明白其中的含義。
