第一次看到這個previous discussion

，如果你使用asp.net MVC，那就試試這個方法在下文

[HttpGet] 
     public JsonResult GetValues() 
     { 
     string responseData; 
     HttpWebResponse response = request.GetResponse() as HttpWebResponse; 
     if (response.StatusCode == HttpStatusCode.OK) 
     { 
     System.IO.StreamReader responseReader = new System.IO.StreamReader(request.GetResponse().GetResponseStream()); 
     responseData = responseReader.ReadToEnd(); 
     }     
     return Json(new { data = responseData}, JsonRequestBehavior.AllowGet); 
     }
