WebService應用一例，帶有安全驗證

一、建立WEB項目，添加WEB服務WebService1.asmx，代碼以下：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Web.Services;
 6 
 7 namespace WebService
 8 {
 9     /// <summary>
10     /// WebService1 的摘要說明
11     /// </summary>
12     [WebService(Namespace = "http://tempuri.org/")]
13     [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
14     [System.ComponentModel.ToolboxItem(false)]
15     // 若要容許使用 ASP.NET AJAX 從腳本中調用此 Web 服務，請取消對下行的註釋。
16     // [System.Web.Script.Services.ScriptService]    
17     public class WebService1 : System.Web.Services.WebService
18     {
19 
20         //聲明Soap頭實例
21         public MySoapHeader myHeader = new MySoapHeader();
22 
23         [System.Web.Services.Protocols.SoapHeader("myHeader")]
24         [WebMethod]
25         public string HelloWorld()
26         {
27             if (isAuthorized)
28             {
29                 return "Hello World";
30             }
31             else
32             {
33                 return "You do not have power to do this operation!";
34             }
35         }
36 
37         [System.Web.Services.Protocols.SoapHeader("myHeader")]
38         [WebMethod]        
39         public string InputYouName(string name)
40         {            
41             if (isAuthorized)
42             {
43                 return "Hello " + name;
44             }
45             else
46             {
47                 return "You do not have power to do this operation!";
48             }
49         }
50 
51         /// <summary>
52         /// 判斷用戶是否得到使用受權
53         /// </summary>
54         public bool isAuthorized
55         {
56             get
57             {
58                 if (myHeader.UserName.Equals("pwd") & myHeader.PassWord.Equals("pwd"))
59                 {
60                      return true;
61                 }
62                 else
63                 {
64                     return false;
65                 }
66             }
67         }
68     }
69 }

二、加入安全驗證，在這個web項目中添加一個類文件MySoapHeader.cs，具體代碼以下：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Web;
 4 
 5 namespace WebService
 6 {
 7     public class MySoapHeader : System.Web.Services.Protocols.SoapHeader
 8     {
 9         private string userName = string.Empty;
10         private string passWord = string.Empty;
11 
12         /// <summary>
13         /// 構造函數
14         /// </summary>
15         public MySoapHeader() { } /// <summary>
16         /// 構造函數
17         /// </summary>
18         /// <param name="userName">用戶名</param>
19         /// <param name="passWord">密碼</param>
20         public MySoapHeader(string userName, string passWord)
21         {
22             this.userName = userName;
23             this.passWord = passWord;
24         }
25 
26         /// <summary>
27         /// 獲取或設置用戶用戶名
28         /// </summary>
29         public string UserName
30         {
31             get { return userName; }
32             set { userName = value; }
34         }
35 
36         /// <summary>
37         /// 獲取或設置用戶密碼
38         /// </summary>
39         public string PassWord
40         {
41             get { return passWord; }
42             set { passWord = value; }
43         }
44     }
45 }

三、客戶端調用，新建一個項目，建立一個控制檯程序，調用示例的詳細代碼以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WebServiceControlClient
{
    class Program
    {
        static void Main(string[] args)
        {
            Service.WebService1SoapClient aa = new Service.WebService1SoapClient();
            Service.MySoapHeader Header = new Service.MySoapHeader();
            Header.PassWord = "pwd";
            Header.UserName = "pwd";
            Console.WriteLine(aa.HelloWorld(Header)+"\n"+aa.InputYouName(Header,"harry"));
            Console.Read();
        }
    }
}
