  • 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。
