Problem when call spring.net webservice from JQuery with POST method.

[adun]

I got a problem when call spring.net web service from JQuery with POST method.
Here is the WebService code:

namespace SprintWS.WS
{
    public interface  ITestWS
    {
        string GetMessage();
        string GetMessage2(string title, string content);
    }
    public class TestWS : ITestWS
    {
        private string message;
        public string Message
        {
            set { message = value; }
        }

        public string GetMessage()
        {
            return this.message;
        }
        public string GetMessage2( string title, string content)
        {
            return title + ":" +  content;
        }
    }
}

And it is configured to TestService.asmx

If I call it in this way, it works well:

    function TestWebService2()
    {
        //TestService.GetMessage2("t", "c");
        //alert("abc");
        $.ajax({
            //type: "POST",
            url: "TestService.asmx/GetMessage2?title=123&content=abc",
            //contentType: "application/json",
            //data: "{title:123,content:ccc}",
            //dataType: "xml",
            success: TestSuccess2,
            error: TestError
        });

    }
    function TestSuccess2(result)
    {
        alert(result.text);
    }
    function TestError2()
    {
    }

And this also works:

    function TestWebService()
    {
        //alert("abc");
        $.ajax({
            type: "POST",
            url: "TestService.asmx/GetMessage",
            //contentType: "application/json",
            data: "{}",
            //dataType: "xml",
            success: TestSuccess,
            error: TestError
        });

    }
    function TestSuccess(result)
    {
        alert(result.text);
    }
    function TestError( error)
    {
    }

But when I call method with parameters, like GetMessage2 with POST method. Like this:

        $.ajax({
            type: "POST",
            url: "TestService.asmx/GetMessage2?title=123&content=abc",
            //contentType: "application/json",
            data: {title:123,content:ccc},
            //dataType: "xml",
            success: TestSuccess2,
            error: TestError
        });

Problem occurs.
I got http response like this:

System.InvalidOperationException: Missing Parameter: title。
   在 System.Web.Services.Protocols.ValueCollectionParameterReader.Read(NameValueCollection collection)
   在 System.Web.Services.Protocols.HtmlFormParameterReader.Read(HttpRequest request)
   在 System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
   在 System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

Does any one knows how to solve this problem?
Thanks, adun.

I don't had this problem while calling Ajax enabled WCF service from JQuery.
