无法通过jQuery / AJAX使用我的Web服务

Question

我的Web服务看起来像这样：

JavaScriptSerializer js = new JavaScriptSerializer();
 [WebMethod]
  public void FormSubmit(agentInfo agentInfoObject)
        {
            string agentID = "";
            string agentName = "";
            try
            {
                if (agentInfoObject != null)
                {
                    agentID = agentInfoObject.agentID;
                    agentName = agentInfoObject.agentName;
                }
                else
                {
                    Console.Write("No Data");
                }
            }
            catch (Exception e)
            {
                Console.Write("Error :" + e.Message);
            }
            RequestBLObject.AgentID = agentInfoObject.agentID;
            RequestBLObject.AgentName = agentInfoObject.agentName;
            BehaviourBLObject.InsertDataBL(RequestBLObject);
        }

进一步将BLL和DAL传递到工作正常的数据库（我使用SoapUI对其进行了测试）。当我尝试将此Web服务链接到我的HTML页面时，我无法获得任何输出。我正在使用JS调用此Web服务，看起来像这样：

$.ajax({
               method: 'POST',
               url: 'http://arohar.com/Service.asmx/FormSubmit',
               data: "{info:" + JSON.stringify(info) + "}",
               contentType: 'application/json; charset=utf-8',
               processData: false,
               dataType: 'JSON',
               success: function() {
                   alert("in success");
               },
               error: function() {
                   alert('in error');
               }
           });

有人可以告诉我代码中哪里出了错吗？为什么我无法访问Web服务？

更新：我的AJAX响应如下所示：

`{"Message":"Invalid web service call, missing value for parameter: \u0027agentInfoObject\u0027.","StackTrace":"   at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}`
