.NET中Web Service实现身份验证策略

下面代码实现Web Service实现身份验证策略，可以看下，挺简单
服务端：
1using System;
2using System.Web;
3using System.Web.Services;
4using System.Web.Services.Protocols;
5
6[WebService(Namespace = "http://livebaby.cn")]
7[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
8public class Service : System.Web.Services.WebService
9{
10    public SecurityHeader currentUser;
11    public Service()
12    {
13
14        //如果使用设计的组件，请取消注释以下行
15        //InitializeComponent();
16     }
17     [WebMethod, SoapHeader("currentUser")]
18    public string GetResult(string queryString)
19    {
20        if(ValidateUser(currentUser.UserName,currentUser.UserPass))
21        {
22            return "你发送的字符串是:"+queryString;
23         }
24        else
25            return "对不起:" + currentUser.UserName+",您不是合法的用户!";
26     }
27    //检验SOAP　HEADER
28    private bool ValidateUser(string user, string pass)
29    {
30        if (user.Equals("user") && pass.Equals("user"))
31            return true;
32        else
33            return false;
34     }
35}
36//自定义Soap Header　Class
37public class SecurityHeader : System.Web.Services.Protocols.SoapHeader
38{
39    public string UserName;
40    public string UserPass;
41}

客户端：

1using System;
2using System.Collections.Generic;
3using System.ComponentModel;
4using System.Data;
5using System.Drawing;
6using System.Text;
7using System.Windows.Forms;
8
9namespace SoapHeader
10{
11    public partial class Form1 : Form
12    {
13        public Form1()
14        {
15             InitializeComponent();
16         }
17
18        private void button_Invoke_Click(object sender, EventArgs e)
19        {
20             SoapHeader.localhost.SecurityHeader header = new SoapHeader.localhost.SecurityHeader();
21             header.UserName = textBox_User.Text;
22             header.UserPass = textBox_Pass.Text;
23             SoapHeader.localhost.Service service = new SoapHeader.localhost.Service();
24             service.SecurityHeaderValue = header;
25            this.textBox_Output.Text+=service.GetResult(this.textBox_Input.Text)+Environment.NewLine;
26         }
27     }
28}
