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

谢谢

错误:

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.

最佳答案

你不明白什么？这个错误几乎不能更具描述性。这是一项安全功能，可防止 JSON hijacking ，你可以像这样禁用它..

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

但您应该了解 implications .
