调用WebService时加入身份验证，以拒绝未授权的访问
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
調(diào)用WebService時加入身份驗證，以拒絕未授權(quán)的訪問 分類： WebService 2010-08-19 16:22 548人閱讀 收藏 舉報 ????? 眾所周知，WebService是為企業(yè)需求提供的在線應(yīng)用服務(wù),其他公司或應(yīng)用軟件能夠通過Internet來訪問并使用這項在線服務(wù)。但在有些時候的某些應(yīng)用服務(wù)不希望被未授權(quán)訪問，那么此時我們可以一下幾種方法來實現(xiàn)身份驗證。
?
方法一：在WebService中引入SoapHeader
[c-sharp] view plain copy print ? #region?配置登錄標頭 ???? ?? ?? public ?class ?MySoapHeader?:?SoapHeader??{?? ????private ?string ?strUserName?=?string .Empty;?? ????private ?string ?strPassWord?=?string .Empty;?? ?? ????public ?MySoapHeader()?{?}?? ?? ????public ?MySoapHeader(string ?username,?string ?password)?? ????{?? ????????this .strUserName?=?username;?? ????????this .strPassWord?=?password;?? ????} ????#region?構(gòu)造?用戶名|密碼 ???????? ?????? ?????? ????public ?string ?UserName?? ????{?? ????????get ?{?return ?strUserName;?}?? ????????set ?{?strUserName?=?value;?}?? ????}?? ?????? ?????? ?????? ????public ?string ?PassWord?? ????{?? ????????get ?{?return ?strPassWord;?}?? ????????set ?{?strPassWord?=?value;?}?? ????} ????#endregion ????#region?檢測是否正確登錄 ???????? ?????? ?????? ?????? ????public ?bool ?CheckLogin()?? ????{?? ????????if ?(strUserName?==?"合法登錄名" ?&&?strPassWord?==?"合法登錄密碼" )?? ????????{?? ????????????return ?true ;?? ????????}?? ????????else ?? ????????{?? ????????????return ?false ;?? ????????}?? ????} ????#endregion ??} #endregion ??#region 配置登錄標頭 /// <summary> /// Code CreateBy BanLao /// </summary> public class MySoapHeader : SoapHeader { private string strUserName = string.Empty; private string strPassWord = string.Empty; public MySoapHeader() { } public MySoapHeader(string username, string password) { this.strUserName = username; this.strPassWord = password; } #region 構(gòu)造 用戶名|密碼 /// <summary> /// 用戶名 /// </summary> public string UserName { get { return strUserName; } set { strUserName = value; } } /// <summary> /// 密碼 /// </summary> public string PassWord { get { return strPassWord; } set { strPassWord = value; } } #endregion #region 檢測是否正確登錄 /// <summary> /// 檢測是否正確登錄 /// </summary> /// <returns></returns> public bool CheckLogin() { if (strUserName == "合法登錄名" && strPassWord == "合法登錄密碼") { return true; } else { return false; } } #endregion } #endregion
?

加入一個服務(wù)用于測試：
?
[c-sharp] view plain copy print ? #region?測試連接 ???[System.Web.Services.Protocols.SoapHeader("myHeader" )]?? ?[WebMethod(Description?=?"判斷用戶是否開通" ,?EnableSession?=?true )]?? ?public ?string ?_GetValue(string ?strInputValue)?? ?{?? ?????if ?(myHeader.CheckLogin())?? ?????{?? ?????????string ?strReturnValue?=?strInputValue?+?"@CopyRight?By?BanLao?2010" ;?? ?????????return ?strReturnValue;?? ?????}?? ?????else ?? ?????{?? ?????????return ?"無效的身份驗證，請重試！" ;?? ?????}?? ?} ?#endregion ?? #region 測試連接 [System.Web.Services.Protocols.SoapHeader("myHeader")] [WebMethod(Description = "判斷用戶是否開通", EnableSession = true)] public string _GetValue(string strInputValue) { if (myHeader.CheckLogin()) { string strReturnValue = strInputValue + "@CopyRight By BanLao 2010"; return strReturnValue; } else { return "無效的身份驗證，請重試！"; } } #endregion
?
?
至此我們想要的需要通過身份驗證的服務(wù)配置好了，下面讓我們進行一些測試，新建一個webForm在Page_Load中：
??
[c-sharp] view plain copy print ? WebLogon.MySoapHeader?myHeader?=?new ?WebLogon.MySoapHeader();?? myHeader.UserName?=?"約定的合法用戶" ;?? myHeader.PassWord?=?"約定的合法密碼" ;?? ?? WebLogon.Service?This_Service?=?new ?WebLogon.Service();?? This_Service.MySoapHeaderValue?=?myHeader;?? Response.Write(This_Service._GetValue("This?is?BanLao's?Test?Application?For?SoapHeader.?" ));?? WebLogon.MySoapHeader myHeader = new WebLogon.MySoapHeader(); myHeader.UserName = "約定的合法用戶"; myHeader.PassWord = "約定的合法密碼"; WebLogon.Service This_Service = new WebLogon.Service(); This_Service.MySoapHeaderValue = myHeader; Response.Write(This_Service._GetValue("This is BanLao's Test Application For SoapHeader. "));
?
?
當運行這個WebForm時，如果用戶名和密碼是正確的我們將看到:
?
This is BanLao's Test Application For SoapHeader.?@CopyRight By BanLao 2010
?
否則
?
無效的身份驗證，請重試！
?
?
方法二：Web Service以Session方式驗證
?
[c-sharp] view plain copy print ? [WebMethod(Description?=?"檢測是否正確登錄" ,?EnableSession?=?true )]?? public ?bool ?CheckLogin(string ?strUserName,?string ?strPassword)??{?? ????if ?(strUserName.Equals("admin" )?&&?strPassword.Equals("123456" ))?? ????{?? ????????Session["LoginState" ]?=?true ;?? ????}?? ????else ?? ????{?? ????????Session["LoginState" ]?=?false ;?? ????}?? ????return ?(bool )Session["LoginState" ];?? } #region?測試連接 ??[WebMethod(Description?=?"測試連接" ,?EnableSession?=?true )]?? public ?string ?_GetValue(string ?strInputValue)??{?? ????if ?(Session["LoginState" ]?==?null ?||?Session["LoginState" ].Equals(false ))?? ????{?? ????????return ?"無效的身份驗證，請重試！" ;?? ????}?? ????else ?? ????{?? ????????string ?strReturnValue?=?strInputValue?+?"@CopyRight?By?BanLao?2010" ;?? ????????return ?strReturnValue;?? ????}?? } #endregion ?? [WebMethod(Description = "檢測是否正確登錄", EnableSession = true)] public bool CheckLogin(string strUserName, string strPassword) { if (strUserName.Equals("admin") && strPassword.Equals("123456")) { Session["LoginState"] = true; } else { Session["LoginState"] = false; } return (bool)Session["LoginState"]; } #region 測試連接 [WebMethod(Description = "測試連接", EnableSession = true)] public string _GetValue(string strInputValue) { if (Session["LoginState"] == null || Session["LoginState"].Equals(false)) { return "無效的身份驗證，請重試！"; } else { string strReturnValue = strInputValue + "@CopyRight By BanLao 2010"; return strReturnValue; } } #endregion
?
?
調(diào)用該服務(wù)，
?
[c-sharp] view plain copy print ? WebLogon.Service?This_Service?=?new ?WebLogon.Service();?? This_Service.CookieContainer?=?new ?System.Net.CookieContainer();?? if ?(This_Service.CheckLogin("admin" ,?"123456" ))??{?? ????Response.Write(This_Service._GetValue("This?is?BanLao's?Test?Application?For?Session.?" ));?? }?? WebLogon.Service This_Service = new WebLogon.Service(); This_Service.CookieContainer = new System.Net.CookieContainer(); if (This_Service.CheckLogin("admin", "123456")) { Response.Write(This_Service._GetValue("This is BanLao's Test Application For Session. ")); }
?
?
當運行這個WebForm時，如果用戶名和密碼是正確的我們將看到:
?
This is BanLao's Test Application For Session.?@CopyRight By BanLao 2010
?
否則
?
無效的身份驗證，請重試！
?
?
注：如果需要多個合法用戶，可以在WebService中聲明判斷即可~
