using System;

using System.Linq;
using System.Web;
using System.Web.Script.Services;
using System.Web.Services;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    [WebMethod]
    public static string GetAllItems(String itemID, String itemName)
    {
        return "Page Method";
    }
}

以上是我创建的代码。

我面临的问题是没有调用webmethod（GetAllItems），但是在ajax调用中，执行成功块并将错误返回为“Authentication failed”。

我也包括我的web.config
