Question

我已经在C＃中使用asp.net构建了一个web服务，并且正在运行 “http://ABC.com/WebSite1/Service.asmx”并且我正在尝试使用jquery ajax异步调用从另一个asp.net网站页面使用此服务。但服务网址没有被点击，我收到错误消息。

This is my webservice:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Xml;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Net.Mail;
using System.Web.Script.Services;

[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. 
[ScriptService]
public class Service : WebService
{
    public Service () {

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

    [WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public void GetUserDetails(string Email, string StreetAddress, string City, string     State, string ZipCode, string Phone) {
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ToString());
    con.Open();
    SqlCommand cmd = new SqlCommand("SELECT * FROM OrderTb WHERE Email = '" + Email + "' AND StreetAddress = '" + StreetAddress + "' AND City = '" + City + "' AND State = '" + State +"' AND ZipCode = '" + ZipCode +"' AND Phone = '"+ Phone + "'", con);
    cmd.ExecuteNonQuery();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    // Create an instance of DataSet.
    DataSet ds = new DataSet();
    da.Fill(ds);
    con.Close();
        }

}

这是我的aspx页面，包括javascript：

Answer 1

我认为您需要在web.config中添加以下内容（在您的网络服务中）

 <system.web>
  <webServices>
    <protocols>
      <add name="HttpGet"/>
      <add name="HttpPost"/>
    </protocols>
  </webServices>

您也可以提供错误，但这不是解决方案

修改

尝试在ajax调用中编写数据值，如下所示：

data: "{ Email: '" + email + "', StreetAddress: '" + street + "', City: '" + city + "', State: '" + state + "', ZipCode: '" + zipCode + "', Phone: '" + phone "'}"

使用ajax异步调用Web服务
