WebService应用一例，带有安全验证

1、创建WEB项目，添加WEB服务WebService1.asmx，代码如下：

 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 的摘要说明

11     /// </summary>

12     [WebService(Namespace = "http://tempuri.org/")]

13     [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

14     [System.ComponentModel.ToolboxItem(false)]

15     // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。

16     // [System.Web.Script.Services.ScriptService]    

17     public class WebService1 : System.Web.Services.WebService

18     {

19 

20         //声明Soap头实例

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         /// 判断用户是否获得使用授权

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 }

2、加入安全验证，在这个web项目中添加一个类文件MySoapHeader.cs，具体代码如下：

 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         /// 构造函数

14         /// </summary>

15         public MySoapHeader() { } /// <summary>

16         /// 构造函数

17         /// </summary>

18         /// <param name="userName">用户名</param>

19         /// <param name="passWord">密码</param>

20         public MySoapHeader(string userName, string passWord)

21         {

22             this.userName = userName;

23             this.passWord = passWord;

24         }

25 

26         /// <summary>

27         /// 获取或设置用户用户名

28         /// </summary>

29         public string UserName

30         {

31             get { return userName; }

32             set { userName = value; }

34         }

35 

36         /// <summary>

37         /// 获取或设置用户密码

38         /// </summary>

39         public string PassWord

40         {

41             get { return passWord; }

42             set { passWord = value; }

43         }

44     }

45 }

3、客户端调用，新建一个项目，创建一个控制台程序，调用示例的详细代码如下：

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();

        }

    }

}
