利用SoapHeader验证web service调用的合法性(dwonmoon)

本文主要通过示例介绍利用SoapHeader验证web service调用的合法性,
一建立Web service项目,新建一个APIService.asmx
其后台代码如下 

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Web.Services.Protocols;

namespace Downmoon.API
{
/// <summary>
/// GlobalSetting的摘要说明
/// </summary>
public class APIService:System.Web.Services.WebService
{
public APIService()
{
// SHeader=newSecuritySoapHeader();
}
public class SecuritySoapHeader:SoapHeader
{
#region Bak
private string _userName = string .Empty;
private string _pwd = string .Empty;
/**/
/// <summary>
/// 用户名
/// </summary>
public string InvokeUserName
{
get
{
return _userName;}
set
{_userName
= value;}
}
/**/
/// <summary>
/// 密码
/// </summary>
public string InvokeUserPwd
{
get
{
return _pwd;}
set
{_pwd
= value;}
}
#endregion
}
#region Members
public SecuritySoapHeaderSHeader = new SecuritySoapHeader();
private string _userName = string .Empty;
private string _pwd = string .Empty;
public string InvokeUserName
{
get
{
return _userName;}
set
{_userName
= value;}
}
public string InvokeUserPwd
{
get
{
return _pwd;}
set
{_pwd
= value;}
}
public static string SecurityUserID
{
get
{
try
{
return System.Configuration.ConfigurationManager.AppSettings[ " SecurityUserID " ].ToString().Trim();
}
catch
{
return " 欢迎与邀月交流,net技术与软件架构 " ;
}
}
}
public static string SecurityUserPWD
{
get
{
try
{
return System.Configuration.ConfigurationManager.AppSettings[ " SecurityUserPWD " ].ToString().Trim();
}
catch
{
return " S2H3I4l5p6q7 " ;
}
}
}

#endregion
#region Methods
#region CheckHeader
public bool IsLegalInvoked()
{
return IsLegalInvoked( this .SHeader);
}
public virtual bool IsLegalInvoked(SecuritySoapHeaderheader)
{
bool bl = false ;
if (header == null )
{
// return"您没有设置SoapHeader,不能正常访问此服务!";
return bl;
}
else if (header.InvokeUserName == null || header.InvokeUserName.Trim().Length == 0 || header.InvokeUserPwd == null || header.InvokeUserPwd.Trim().Length == 0 )
{
return bl;}
if (header.InvokeUserName.Trim() != SecurityUserID || header.InvokeUserPwd.Trim() != SecurityUserPWD)
{
// return"您提供的身份验证信息有误,不能正常访问此服务!";
return bl;
}
bl
= true ;
return bl;
}
#endregion

#region ERRORHandle
private clsBasePagebp;
public void ErrorHandle( string strMessage)
{
if (bp == null )
{
bp
= new clsBasePage();

}
else
{
bp.ErrorStop(strMessage);
return ;
}
}

#endregion

#endregion

}
}




二、添加一个PassPort.asmx,继承APIWebService,主要是为了重用SoapHeader,
调用方法如下(红色代码部分):

using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.ComponentModel;
namespace Downmoon.API
{
/// <summary>
/// PassPort的摘要说明DownmoonLastModified
/// </summary>
[WebService(Namespace = " 欢迎与邀月交流,net技术与软件架构.API " )]
[WebServiceBinding(ConformsTo
= WsiProfiles.BasicProfile1_1)]
public class PassPort:APIService
{
public PassPort()
{
}

#region Members
#endregion
#region Methods

#region测试安全信息
[WebMethod(Description="TestSafeInvoke",EnableSession=true,CacheDuration=30),SoapHeader("SHeader")]
publicstringHelloWorld()
{
if(IsLegalInvoked())
{
return"Suceed!";
}
else{
return"IllegalInvoke!";
}
}
#endregion

#endregion
}
}


三、建立Vs2005测试项目,并添加一个测试类(vs2005会自动生成,呵呵)
修改后代码如下:

// 以下代码由MicrosoftVisualStudio2005生成。
// 测试所有者应该检查每个测试的有效性。
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using System.Text;
using System.Collections.Generic;
namespace TestAPI2005
{
/// <summary>
/// 这是Downmoon.API.PassPort的测试类,旨在
/// 包含所有Downmoon.API.PassPort单元测试
/// </summary>
[TestClass()]
public class PassPortTest
{

private TestContexttestContextInstance;

/// <summary>
/// 获取或设置测试上下文,上下文提供
/// 有关当前测试运行及其功能的信息。
/// </summary>
public TestContextTestContext
{
get
{
return testContextInstance;
}
set
{
testContextInstance
= value;
}
}

#region 附加测试属性
// 编写测试时,可使用以下附加属性:
#region InitTest
public static string invokeusername;
public static string invokeuserpwd;
public static string username;
public static string userIP;
public static string ConnKey;
public static string ConnValue;
public static int rowCount;
public static DateTimeldNow;
#endregion
[ClassInitialize()]
public static void MyClassInitialize(TestContexttestContext)
{
invokeusername
= " 欢迎与邀月交流,net技术与软件架构 " ;
invokeuserpwd
= " S2H3I4l5p6q7 " ;
username
= " 欢迎与邀月交流,net技术与软件架构 " ;
userIP
= " 10.103.33.6 " ;
ConnKey
= "" ;
ConnValue
= "" ;
rowCount
= 0 ;
ldNow
= DateTime.Now;
}
[ClassCleanup()]
public static void MyClassCleanup()
{
invokeusername
= null ;
invokeuserpwd
= null ;
}
// 使用TestInitialize在运行每个测试前先运行代码
// [TestInitialize()]
// publicvoidMyTestInitialize()
// {
// }
// 使用TestCleanup在运行完每个测试后运行代码
// [TestCleanup()]
// publicvoidMyTestCleanup()
// {
// }
#endregion

#region HelloWorld()的测试
/// <summary>
/// HelloWorld()的测试
/// </summary>
[TestMethod]
public void HelloWorldTest()
{
try
{
TestAPI.PassPort.PassPorttarget
= new TestAPI.PassPort.PassPort();
target.SecuritySoapHeaderValue
= new TestAPI.PassPort.SecuritySoapHeader();
target.SecuritySoapHeaderValue.InvokeUserName
= invokeusername;
target.SecuritySoapHeaderValue.InvokeUserPwd
= invokeuserpwd;
string str = target.HelloWorld();
Console.WriteLine(str);
// Console.WriteLine("Result:"+str);
Assert.AreEqual(str, " Suceed! " , false );
}
catch (Exceptionex)
{
Assert.Fail(
" 单元测试生成错误: " + ex.Message);
/// /Console.WriteLine(ex.Message);
}
}
#endregion
}
}


四、在测试管理器中勾选该测试类

右键“运行选中的测试”,即可看到运行结果:通过!
标准输出 Suceed!
此时如果在浏览器中直接调用该服务,将会出现 “Illegal Invoke!”

OK! 结束

以上代码适用于.net 2.0及Vsts 2005。应该也可以适用于vs2003。
