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 = new SecuritySoapHeader();
}
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 SecuritySoapHeader SHeader = 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(SecuritySoapHeader header)
{
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 clsBasePage bp;
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 Downmoon Last Modified
/// </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 = "Test Safe Invoke", EnableSession = true, CacheDuration = 30),SoapHeader("SHeader")]
public string HelloWorld()
{
if(IsLegalInvoked())
{
return "Suceed!";
}
else{
return "Illegal Invoke!";
}
}
#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 Microsoft Visual Studio 2005 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 TestContext testContextInstance;

/// <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 TestContext TestContext
{
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 DateTime ldNow;
#endregion
[ClassInitialize()]
public static void MyClassInitialize(TestContext testContext)
{
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()]
//public void MyTestInitialize()
//{
//}
//使用 TestCleanup 在运行完每个测试后运行代码
//[TestCleanup()]
//public void MyTestCleanup()
//{
//}
#endregion

#region HelloWorld () 的测试
/// <summary>
///HelloWorld () 的测试
///</summary>
[TestMethod]
public void HelloWorldTest()
{
try
{
TestAPI.PassPort.PassPort target = 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 (Exception ex)
{
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。
