Ajax 不调用 Web 服务

Question

我正在尝试从 ajax 调用 Web 服务并获取字符串数组作为回报，但无论我做什么，我在控制台日志中都出现 404 错误。

这是我的客户端代码：

 $.ajax({
        url: "http://localhost:55397/WebService1.asmx/GetList",
        cache: false, type: "POST", contentType: "application/json; charset=utf-8",

        dataType: 'json',
        success: function (data) {
            tags = data.d;
        },
        error: function () { alert("AutoComplete Server not found");}
    });

这是我的网络服务代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using ExpressDeal.Models;
using ExpressDeal.Controllers;
using System.Web.Script.Services;


namespace ExpressDeal
{
    /// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

    public class WebService1 : System.Web.Services.WebService
    {
        private BaseLogic bl = new BaseLogic();

        [WebMethod]
        [ System.Web.Script.Services.ScriptMethodAttribute()]
        //[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Xml)]
        public string [] GetList()
        {
            return bl.Context.Items.Select(i=>i.Name).ToArray();
        }
    }
}

谁能告诉我它有什么问题以及如何使它工作？

尝试将您的方法设置为静态：

        [WebMethod]
        [ System.Web.Script.Services.ScriptMethodAttribute()]
        //[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Xml)]
        public static string [] GetList()
        {
            return bl.Context.Items.Select(i=>i.Name).ToArray();
        }
