做個CMS吧(二)-Forms登陸驗證

添加NuGet庫：System.Web.Security

一·配置web.config

創建Admin文件夾，并添加web.config文件在<system.web>節點內加入如下節點：

   1:  <authorization><!--禁止未通過的用戶訪問--> 

   2:      <deny user="?"></deny>

   3:  </authorization>

二·創建Login頁面

這個“玩意”的登陸頁面的文件名及目錄結構必須是這樣的“～/Account/Login.cshtml”;關鍵代碼如下：

   1:  <form  method="post">

   2:     帳號<input name="user" type="text" />

   3:     密碼<input name="pass" type="passWord" />

   4:     <input name="login" type="submit" value="登錄" class="button" />

   5:  </form>

邏輯代碼：

1: @{

   2:      var returnUrl = Request.QueryString["ReturnUrl"];

   3:      if(returnUrl.IsEmpty()){

   4:          returnUrl = "~/Admin/";

   5:      }

   6:      if(IsPost){

   7:          var username = Request.Form["user"];

   8:          var password = Request.Form["pass"];

   9:          var nickname = "";

  10:          var y = FormsAuthentication.HashPasswordForStoringInConfigFile(username+password,"md5");

  11:          var db = Database.Open("RazorCMS");

  12:          var sqlSel = "select TOP 1 username,password,nickname from SiteSet";

  13:          var user = db.QuerySingle(sqlSel);

  14:          var x = FormsAuthentication.HashPasswordForStoringInConfigFile(user["username"]+user["password"],"md5");

  15:          if(x==y){

  16:              nickname = user["nickname"];

  17:              FormsAuthentication.RedirectFromLoginPage(nickname,true);

  18:          }

  19:      }

  20:  }

請高手解答：為什么我請求Admin目錄不能定位到Default.cshtml

問題結局了。單詞打錯了。囧

三·創建Default.cshtml

證明趨勢登陸成功：

   1:  @{

   2:      var n = Context.User.Identity.Name;

   3:  }
