Question

我已经阅读了很多关于jquery的内容，我有一个简单的web服务返回一个方法。现在我想在dotnetnuke中使用jquery调用该webservice但是我收到一个错误，说找不到文件（错误号404）。

这是我的代码：

WEBSERVICE

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;


/// <summary>
/// Summary description for TestPost
/// </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]
public class TestPost : System.Web.Services.WebService {


public TestPost () {


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


[WebMethod]
[System.Web.Script.Services.ScriptMethod()]
public Names[] GetNames()
{
    List<Names> list = new List<Names>();
    DataTable dt = DataStore.GetDataTable();
    foreach (DataRow row in dt.Rows)
    {
        Names _names = new Names();
        _names.FirstName = row["Name"].ToString();
        _names.Age = row["age"].ToString();
        list.Add(_names);
    }
    return list.ToArray();
}

}
public class DataStore
{
    public static DataTable GetDataTable()
{      
    DataTable dt = new DataTable("Names");
    DataColumn dc1 = new DataColumn("Name");
    DataColumn dc2 = new DataColumn("Age");
    dt.Columns.AddRange(new DataColumn[] { dc1, dc2 });
    DataRow dr1 = dt.NewRow();
    dr1[0] = "Ahmed";
    dr1[1] = "27";
    DataRow dr2 = dt.NewRow();
    dr2[0] = "Peter";
    dr2[1] = "30";
    DataRow dr3 = dt.NewRow();
    dr3[0] = "John";
    dr3[1] = "20";
    DataRow dr4 = dt.NewRow();
    dr4[0] = "Ali";
    dr4[1] = "30";
    dt.Rows.Add(dr1);
    dt.Rows.Add(dr2);
    dt.Rows.Add(dr3);
    dt.Rows.Add(dr4);
    return dt;
}
}


public class Names
{
private string _firstName;
private string _age;
public string FirstName
{
    get { return _firstName; }
    set { _firstName = value; }
}
public string Age
{
    get { return _age; }
    set { _age = value; }
}
}

}

请查看我的代码，看看我是否做错了。

在我看来，ASMX文件的路径不正确（因此404）。试试这个：

url: '<%=ResolveUrl("TestPost.asmx/GetNames")%>'

由于您是从DNN模块调用此函数，因此相对于当前模块控件的路径不太可能到达正确的位置;你需要相对于页面的路径，并且在编译时你不会知道。 ResolveUrl会为您提供一个可在当前页面上运行的网址，无论其位于何处。
