用SOAP处理WEBSERVICE的安全性

最近在项目中遇到WEBSERVICE的安全性问题,本来,按以前的经验(WIINFORM中),可以在服务器端建一个用户表,进行身份验证,但后来发现,这存在安全性问题,所以查找后发现可以利用定义SOAP头进行用户信息绑定进行身份验证,下面就是相关代码,验证通过.

这里是SOAP头定义:
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

public class MyHeader :  System.Web.Services.Protocols.soapHeader
     {
         private string _UserID=string.Empty;
         private string _PassWord=string.Empty;
         /// <summary>
         /// 构造函数
         /// </summary>
         public MyHeader()
         {
         }
         /// <summary>
         /// 构造函数
         /// </summary>
         /// <param name="nUserID">用户ID</param>
         /// <param name="nPassWord">加密后的密码</param>
         public MyHeader(string nUserID,string nPassWord)
         {
              Initial(nUserID,nPassWord);
         }
        
         #region 属性
         /// <summary>
         /// 用户名
         /// </summary>
         public string UserID
         {
              get{return _UserID;}
              set{_UserID=value;}
         }
         /// <summary>
         /// 加密后的密码
         /// </summary>
         public string PassWord
         {
              get{return _PassWord;}
              set{_PassWord=value;}
         }
       #endregion
         #region 方法
       /// <summary>
         /// 初始化
         /// </summary>
         /// <param name="nUserID">用户ID</param>
         /// <param name="nPassWord">加密后的密码</param>
         public void Initial(string nUserID,string nPassWord)
         {
              UserID=nUserID;
              PassWord=nPassWord;
         }
         /// <summary>
         /// 用户名密码是否正确
         /// </summary>
         /// <param name="nUserID">用户ID</param>
         /// <param name="nPassWord">加密后的密码</param>
         /// <param name="nMsg">返回的错误信息</param>
         /// <returns>用户名密码是否正确</returns>
         public bool IsValid(string nUserID,string nPassWord,out string nMsg)
         {
              nMsg="";
              try
              {
                   //判断用户名密码是否正确
                   if(nUserID == "admin" && nPassWord == "admin"){
                       return true;
                   }
                   else
                   {
                       nMsg="对不起，你无权调用此Web服务，可能有如下原因：/n 1.您的帐号被管理员禁用。/n 2.您的帐号密码不正确";
                       return false;
                   }
              }
              catch
              {
                   nMsg="对不起，你无权调用此Web服务，可能有如下原因：/n 1.您的帐号被管理员禁用。/n 2.您的帐号密码不正确";
                   return false;
              }
         }
         /// <summary>
         /// 用户名密码是否正确
         /// </summary>
         /// <returns>用户名密码是否正确</returns>
         public bool IsValid(out string nMsg)
         {
              return IsValid(_UserID,_PassWord,out nMsg);
         }
         #endregion
}

服务器部分:
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

 

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class myService : System.Web.Services.WebService
{
    /// <summary>
    /// Soap头实例
    /// </summary>
    public MyHeader myHeader = new MyHeader();
      
    public myService()
    {

    }
    // WEB 服务示例
    // HelloWorld() 示例服务返回字符串 Hello World
    // 若要生成，请取消注释下列行，然后保存并生成项目
    // 若要测试此 Web 服务，请按 F5 键
    [WebMethod]
    public string HelloWorld()
    {
        return "Hello World";
    }
    [SoapHeader("myHeader",Direction = SoapHeaderDirection.InOut)]
    [WebMethod(Description = "ddddddd",EnableSession = true)]
    public string HelloWorld2(string contents)
    {
        string msg = "";
        //验证是否有权访问
        if (!myHeader.IsValid(out  msg))
            return msg;
        return "Hello World:" + contents;
    }

   
}

其实原理就是定义一个SOAP头后,在客户端调用该头并注入身份信息,这样在网络上即使给截获了.也取不到身份信息.

小东西做完以后就想到了发布,感觉用VS2005的CLICKONCE方便好用,这里就不说了...随便查查就N多
