Question

抱歉我的英文

我创建了一个包含一些aspx页面的网站，例如Default.aspx，以及一个名为DataService.asmx的Web服务。在Default.aspx页面中，我想使用jquery调用Web服务。问题是我无法使用jquery

调用Web服务

我在ubuntu服务器版本10.04上使用mono 2.4.4。

如何使用javascript和jquery来使用Web服务？

请帮助我，谢谢

使用萤火虫我看到了

Object reference not set to an instance of an object
Description: HTTP 500. Error processing request.
Stack Trace: System.NullReferenceException: Object reference not set to an instance of  an object at System.Web.Script.Services.WebServiceData.GetWebServiceData  (System.Web.HttpContext context, System.String virtualPath, Boolean failIfNoData, Boolean PageMethods) [0x00000 ] at System.Web.Script.Services.WebServiceData.GetWebServiceData (System.Web.HttpContext context, System.String virtualPath) [0x00000] at System.Web.Script.Services.RestHandler.CreateHandler (System.Web.HttpContext context) [ 0x00000] at System.Web.Script.Services.RestHandlerFactory.GetHandler (System.Web.HttpContext context, RequestType System.String, System.String url, pathTranslated System.String) [0x00000] at System.Web.Script.Services.ScriptHandlerFactory .

版本信息：运行时：单声道2.4.4 ASP.NET版本：2.0.50727.1433

网络服务代码（DataService.asmx）

[WebService (Namespace = "http://tempuri.org/")]
[WebServiceBinding (ConformsTo WsiProfiles.BasicProfile1_1 =)]
[ScriptService ()]
public class DataService: System.Web.Services.WebService
{
    [WebMethod]
    [ScriptMethod (ResponseFormat = ResponseFormat.Json, XmlSerializeString = false)]
    public string SayHello ()
    {
        return "Hello !!!";
    }

}

Javascript（Default.aspx）

$ (Document). Ready (function () {

        $.Ajax ({
            type: "POST",
            url: _webServiceAddress + method,
            Date: parameters,
            contentType: "application / json, charset = utf-8",
            dataType: "json",
            success: function (data) {alert (data);}
            error: function () {alert ("Error");}
        });

    });

这是JavaScript代码。另一个是错的，对不起

$(document).ready(function () { 
        $.ajax({ 
            type: "POST", 
            url: "DataService.asmx/SayHello", 
            data: "{}", 
            contentType: "application/json; charset=utf-8", 
            dataType: "json", 
            success: function () { alert("Ok"); }, 
            error: function () { alert("Error"); } 
        }); 
    });

您的javascript不正确：

$ (document). ready (function () {

    $.ajax ({
        type: "POST",
        url: _webServiceAddress + method,
        data: parameters,
        contentType: "application/json,charset=utf-8",
        dataType: "json",
        success: function (data) {alert (data);},
        error: function () {alert ("Error");}
    });

});

记下大写，数据不是日期，以及逗号分隔成功和错误。

目前我认为无法从ajax调用调用MyService.asmx / MyMethod。总是返回500。我几周都在寻求解决方案，现在我正在用基于ServiceStack.NET的服务取代.asmx。
