ajax跨域访问远程webservice、ashx的解决方法

1.HTML页面,主要是公文流转的webservice跨域，内外网邮箱的ashx跨域(用$.getJSON解决)

        //公文流转
        $(function(){
            $.ajax({
                type:"POST",
                url:"wsOADoc.asmx/GetDocCount",
                data:{"utName":"linshan"},
                success: function(strNum) {
                    var xmlMsg = strNum.getElementsByTagName("int");
                    var txt = xmlMsg[0].childNodes[0].nodeValue;
                    $("#strCount").html(txt);
                }
            });
        });
        
        //内网邮箱
        $(function(){
            var url = 'http://10.72.8.235/Mail.ashx';
            $.getJSON(url+'?callback=?',{userName:'linshan'},
                 function(result){
                    $("#InnerMail").html(result.UnReadMailCount);
                 }
            )
        })
        
         //外网邮箱
        $(function(){
            var url = 'http://10.72.8.235/wideMail.ashx';
            $.getJSON(url+'?callback=?',{userName:'linshan'},
                 function(result){
                    $("#wideMail").html(result.UnReadMailCount);
                 }
            )
        })

 

2.跨域webservice解决：在本地建立一个代理，用于转换

using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;


/// <summary>
/// wsOADoc 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class wsOADoc : System.Web.Services.WebService {

    public wsOADoc () {

        //如果使用设计的组件，请取消注释以下行 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string HelloWorld() {
        return "Hello World";
    }

    [WebMethod]
    public int GetDocCount(string utName)
    {
        DocuOA.TodayAffair ta = new DocuOA.TodayAffair();
        int strNum = Convert.ToInt32(ta.utGetTodayDocuOA3Count(utName));
        if (strNum >= 0)
        {
            return strNum;
        }
        else
        {
            return -1;
        }
    }
    
}
