ASP.NET MVC 2 – 与jQuery的Ajax响应失败

我不明白这个错误，不要在“JsonResult Test（）”中产生错误，我正在做其他项目，如ASP.NET MVC

谢谢

错误：

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的

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

你不明白什么？ 这个错误很难描述。 这是一个防止JSON劫持的安全function，你可以像这样禁用它。

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

但你应该明白这个含义 。
