为WebService添加身份验证的两种方法

方法一：SoapHeader

辅助类：MySoapHeader

     //SoapHeader 添加引用
     using System.Web.Services.Protocols;

     #region 配置登录标头

     public class MySoapHeader:SoapHeader
     {
         private string _strUserName = string.Empty;
         private string _strPassWord = string.Empty;

         #region 构造方法
         public MySoapHeader() { }

         public MySoapHeader(string userName, string passWord)
         {
             _strUserName = userName;
             _strPassWord = passWord;
         }
         #endregion

         #region 构造用户名|密码
         /// <summary>
         /// 用户名
         /// </summary>
         public string UserName
         {
             get { return _strUserName; }
             set { _strUserName = value; }
         }
         /// <summary>
         /// 密码
         /// </summary>
         public string PassWord
         {
             get { return _strPassWord; }
             set { _strPassWord = value; }
         }
         #endregion

         #region 检测是否正常登录
         public bool CheckLogin()
         {
             if (_strUserName == "hkl" && _strPassWord == "")
             {
                 return true;
             }
             else return false;
         }
         #endregion

     }

     #endregion

WebService代码

         public MySoapHeader myHeader = new MySoapHeader();

         [System.Web.Services.Protocols.SoapHeader("myHeader")]
         [WebMethod(Description = "判断用户是否开通", EnableSession = true)]
         public string GetValue(string strInputValue)
         {
             if (myHeader.CheckLogin())
             {
                 string strReturnValue = strInputValue + "@身份验证已通过";
                 return strReturnValue;
             }
             else return "身份无效，请重试！";
         }

新建一个web网页并添加web引用，在pageload方法中添加如下代码

             localhost1.MySoapHeader myHeader = new localhost1.MySoapHeader();
             myHeader.UserName = "hkl";
             myHeader.PassWord = "";

             localhost1.Service1 myTest = new localhost1.Service1();
             myTest.MySoapHeaderValue = myHeader;
             Response.Write(myTest.GetValue("This's my test Application for SoapHeader."));

运行即可查看结果。

方法二：Session

　　WebService代码

         [WebMethod(Description = "检测是否通过验证", EnableSession = true)]
         public bool CheckLogin(string strUserName, string strPassWord)
         {
             if (strUserName.Equals("xxx") && strPassWord.Equals(""))
             {
                 Session["LoginState"] = true;
             }
             else Session["LoginState"] = false;

             return (bool)Session["LoginState"];
         }

         [WebMethod(Description = "测试连接", EnableSession = true)]
         public string GetValue(string strInputValue)
         {
             if (Session["LoginState"] == null || Session["LoginState"].Equals(false))
             {
                 return "无效身份，请重试！";
             }
             else
             {
                 string strReturnValue = strInputValue + "@身份验证已通过";
                 return strReturnValue;
             }
         }

新建一个web网页并添加web引用，在pageload方法中添加如下代码

             localhost2.Service2 myTest = new localhost2.Service2();
             myTest.CookieContainer = new System.Net.CookieContainer();
             if (myTest.CheckLogin("xxx", ""))
             {
                 Response.Write(myTest.GetValue("This is my test application for session."));
             }

运行即可查看结果。
