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。
