如何在.Net 2.0中创建支持Ajax的Web服务

How to create Ajax Enabled Webservice in .Net 2.0

function Likes_Count() {

            debugger;
       // alert(row);
       $.ajax({
           type: "POST",
           contentType: "application/json; charset=utf-8",
           url: "http://localhost:1157/WebSite2/likes/likesservice.asmx/LikesCount",
           //data: '{"Cat":' + cat + ',"title":' + title + '}',
           data: "{ 'Cat': '" + cat + "','title': '" + title + "'}",
           dataType: "json",
           success: function (data) {
               $("#likes_count").html(data.d);
           },
           error: function (result) {
               alert("Error");
           }
       });

   }

   window.onload = Likes_Count;

网络服务代码

webservice code

using System;
using System.Collections.Generic;

using System.Web;
using System.Web.Services;
using System.Web.Script.Services;

/// <summary>
/// Summary description for LikesService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
    [ScriptService]
public class LikesService : System.Web.Services.WebService {

    public LikesService () {

        //Uncomment the following line if using designed components
        //InitializeComponent();
    }

    [WebMethod]
    public string AddLikes(string cat, string title)
    {
        return cat;
       
    }

    [WebMethod]
    public string[] Likes_Count()
    {
        string[] arr4 = new string[1];
        arr4[0] = "Success";
        return arr4;
    }

    [WebMethod]
    public string LikesCount(string Cat, string title)
    {

        return "98948";
        
    }

}

< b。在.net 2.0中找不到System.Web.Script.Services 名称空间。但是在3.5和4.0中找到了

这个代码在3.5和4.0中运行良好



所以请告诉替代方法创建一个启用ajax的webservice .net 2.0

System.Web.Script.Services namespace is not found in .net 2.0. but found in 3.5 and 4.0
this code works well in 3.5 and 4.0

so please tell the alternate way to create ajax enabled webservice in .net 2.0

推荐答案

.ajax（{
type： POST，
contentType： application / json; charset = utf -8，
url： http：// localhost：1157 / WebSite2 / likes /likesservice.asmx/LikesCount，
// data：'{Cat： '+ cat +'，title：'+ title +'}'，
data： {'Cat'：' + cat + '，'title'：' + title + '}，
dataType： json ，
成功： function （data）{

.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://localhost:1157/WebSite2/likes/likesservice.asmx/LikesCount", //data: '{"Cat":' + cat + ',"title":' + title + '}', data: "{ 'Cat': '" + cat + "','title': '" + title + "'}", dataType: "json", success: function (data) {

（ ＃likes_count）。html（data.d）;
}，
错误： function （结果）{
alert（ 错误）;
}
}）;

}

window .onload = Likes_Count;

("#likes_count").html(data.d); }, error: function (result) { alert("Error"); } }); } window.onload = Likes_Count;
