我想用JQuery Mobile和PhoneGap構建移動應用程序。這個應用程序將打到我正在與ASP.NET MVC 3工作的後端。現在，我只是想獲得一個基本的GET/POST工作。我創建了以下測試頁面。通過JQuery Mobile/PhoneGap和ASP.NET MVC跨域服務調用3

當我在Visual Studio中運行此頁面時，我將AJAX url調用更改爲相對調用。他們完美地工作。但是，因爲我的目標是從PhoneGap內部運行此應用程序，所以我知道該頁面實際上將作爲本地文件運行（http://jquerymobile.com/demos/1.1.0/docs/pages/phonegap.html）。因此，我使用了上面的代碼，並在本地機器上創建了test.html。
當我嘗試運行這段代碼時，Twitter測試就起作用了。奇怪的是，所有這三項操作都在Internet Explorer中運行。但是，當我使用Chrome或FireFox時，測試到我的服務器不起作用。在Chrome中，我注意到控制檯中的以下內容：
XMLHttpRequest cannot load https://www.mydomain.com/myService/testGet?q=1. Origin null is not allowed by Access-Control-Allow-Origin.
XMLHttpRequest cannot load https://www.mydomain.com/myService/testPost. Origin null is not allowed by Access-Control-Allow-Origin.
我回顧了這個：Ways to circumvent the same-origin policy。但是，他們似乎都沒有工作。我覺得有一些服務器端配置我錯過了。目前，我的TestGet和TestPost操作如下所示：
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult TestGet(string q)
{
Response.AppendHeader("Access-Control-Allow-Origin", "*");
return Json(new { original = q, response=DateTime.UtcNow.Millisecond }, JsonRequestBehavior.AllowGet);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult TestPost(string data)
{
Response.AppendHeader("Access-Control-Allow-Origin", "*");
return Json(new { status=1, response = DateTime.UtcNow.Millisecond }, JsonRequestBehavior.AllowGet);
}
我覺得我很接近完成這項工作。我錯過了什麼？ Anyhelp真誠地感謝。
在post方法中不需要'JsonRequestBehavior.AllowGet' – Rafay
