The web service is defined as the following:
-------------------------------------------------------------------------------------------
using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Script.Services;
/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/";)]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class WebService : System.Web.Services.WebService
{
public WebService()
{
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string HelloWorld(string haha)
{
string temp = "[{'key':'1', 'value':';lakjshf 787agf8 ..1671
111'},{'key':'2', 'value':'[lakjshf 787agf8 ..1671 111'},{'key':'3',
'value':'[lakjshf 787agf8 ..1671 333'}]";
return temp;
}
}
---------------------------------------------------------------------------------------------

once passing some parameters in, the following error shows:
------------------------------------------------------------------------------------------------------------------------
System.InvalidOperationException: Request format is invalid:
application/json; charset=utf-8.
System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
