我正在尝试使用ASP.NET 3.5中的Web服务从数据库填充列表
与C#和jquery移动。

当我运行站点时,它运行良好,但是当我将其发布到服务器时,它不会填充列表,并且ajax错误函数会捕获错误。
这是我的代码。

我的网络服务:

public class product
{
    //[product] ,[img1] ,[descr]
    public string name;
    public string img1;
    public string descr;

}

[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 CarService : System.Web.Services.WebService {


[WebMethod]
    public List<product> GetAllProducts()
    {
        List<product> productt = new List<product> {};

        string query = "SELECT [product] ,[img1] ,[descr] FROM [ELQ].[dbo].[products]";
        SqlCommand cmd = new SqlCommand(query);
        DataSet ds = GetData(cmd);
        DataTable dt = ds.Tables[0];

        // Process each employee record in table...
        //foreach (DataRow dr in dt.Rows)
        foreach(DataRow item in ds.Tables[0].Rows)
        {
            //productt.Add((DataRow) row);
            product pro = new product();
            pro.name = item["product"].ToString();
            pro.img1 = item["img1"].ToString();
            pro.descr = item["descr"].ToString();
            productt.Add(pro);
        }

        return productt;
    }
    public static string GetShipDetails()
    {

        string query = "SELECT [product] ,[img1] ,[descr] FROM [ELQ].[dbo].[products]";
        SqlCommand cmd = new SqlCommand(query);
        return GetData(cmd).GetXml();
    }
    private static DataSet GetData(SqlCommand cmd)
    {
        string connString = "Data Source=GHOST-PC\\STC;Initial Catalog=ELQ;Integrated Security=True";
        using (SqlConnection con = new SqlConnection(connString))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                using (DataSet ds = new DataSet())
                {
                    sda.Fill(ds);
                    return ds;
                }
            }
        }
    }


}

它看起来像json响应错误并生成错误,但是当我从笔记本电脑执行代码时,它工作正常。
我不知道我想念的是什么,请帮助我。

错误:

最佳答案

我修复了错误,实际上这不是错误,我在数据库中登录并遇到身份验证问题,所以我决定将代码发布给像我这样的初学者,所以这是我的代码

首先,我建立了一个服务来处理我的数据库,然后我使用了一种简单的方法

这是我的CarService类别

using System;
using System.Collections.Generic;
//using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data.SqlClient;
//using System.Web.Script.Serialization;
using System.Web.Script.Services;
using System.IO;
//using Newtonsoft.Json;
using System.Data;
using System.Text;



/// <summary>
/// Summary description for CarService

[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 CarService : System.Web.Services.WebService {

    public class product
    {
        public string name;
        public string img1;
        public string descr;

    }

    static List<product> productt = new List<product> { };

    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    [WebMethod]
    public List<product> GetAllProducts()
    {

        string query = "SELECT  [product] ,[img1] ,[descr] FROM [ELQ].[dbo].[products]";
        SqlCommand cmd = new SqlCommand(query);
        DataSet ds = GetData(cmd);
        DataTable dt = ds.Tables[0];
        foreach(DataRow item in ds.Tables[0].Rows)
        {
            product pro = new product();
            pro.name = item["product"].ToString();
            pro.img1 = item["img1"].ToString();
            pro.descr = item["descr"].ToString();
            productt.Add(pro);
        }

        return productt;
    }

    private static DataSet GetData(SqlCommand cmd)
    {
        string connString = "Data Source=GHOST-PC\\STC;Initial Catalog=ELQ;Persist Security Info=True;User ID=sa;Password=seif@ghost";
        string str = "Data Source=GHOST-PC\\STC;Initial Catalog=ELQ;Persist Security Info=True;User ID=sa;Password=seif@ghost";
        using (SqlConnection con = new SqlConnection(str))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                using (DataSet ds = new DataSet())
                {
                    sda.Fill(ds);
                    return ds;
                }
            }
        }
    }


}


然后这是我的包
