asp.net2.0角色管理，详细步骤

step 1:

C# code

   
     

    
      
    
       
    
      <
    
      authentication mode
    
      =
    
      "
    
      forms
    
      "
    
      >
    
       
    
      <
    
      forms name
    
      =
    
      "
    
      .ASPXAUTH 
    
      "
    
       loginUrl
    
      =
    
      "
    
      /login.aspx
    
      "
    
       timeout
    
      =
    
      "
    
      30
    
      "
    
       path
    
      =
    
       
    
      "
    
      /
    
      "
    
      >
    
       
    
      </
    
      forms
    
      >
    
       
    
      </
    
      authentication
    
      >
    
       
   
     

step 2:
需要角色控制的目录下新建web.config,如以下配置

C# code

   
     

    
      
    
       
    
      <
    
      authorization
    
      >
    
       
    
      <
    
      allow users
    
      =
    
      "
    
      comma-separated list of users
    
      "
    
       roles
    
      =
    
      "
    
      comma-separated list of roles
    
      "
    
       verbs
    
      =
    
      "
    
      comma-separated list of verbs
    
      "
    
       
    
      />
    
       
    
      <
    
      deny users
    
      =
    
      "
    
      comma-separated list of users
    
      "
    
       roles
    
      =
    
      "
    
      comma-separated list of roles
    
      "
    
       verbs
    
      =
    
      "
    
      comma-separated list of verbs
    
      "
    
       
    
      />
    
       
    
      </
    
      authorization
    
      >
    
       
   
     

step 3:
登录代码，获得船票

C# code

   
     

    
      
    
      FormsAuthenticationTicket Ticket 
    
      =
    
       
    
      new
    
       FormsAuthenticationTicket (
    
      1
    
      ,user,DateTime.Now,
   
     

   
     

    
       
    
      DateTime.Now.AddMinutes(
    
      30
    
      ), 
    
      false
    
      ,userRoles,
    
      "
    
      /
    
      "
    
      ) ; 
    
      //
    
      建立身份验证票对象
    
       
    
       
    
      string
    
       HashTicket 
    
      =
    
       FormsAuthentication.Encrypt (Ticket) ; 
    
      //
    
      加密序列化验证票为字符串
    
       
    
       HttpCookie UserCookie 
    
      =
    
       
    
      new
    
       HttpCookie(FormsAuthentication.FormsCookieName, HashTicket) ; 
    
      //
    
      生成Cookie
    
       
    
       Context.Response.Cookies.Add (UserCookie) ; 
    
      //
    
      Cookie
    
       
    
       
   
     

step 4:（手工创建角色）
在global.asax 中

C# code

   
     

    
      
    
      protected
    
       
    
      void
    
       Application_AuthorizeRequest(
    
      object
    
       sender, System.EventArgs e) { HttpApplication App 
    
      =
    
       (HttpApplication) sender; HttpContext Ctx 
    
      =
    
       App.Context ; 
    
      //
    
      获取本次Http请求相关的HttpContext对象
    
       
    
       
    
      if
    
       (Ctx.Request.IsAuthenticated 
    
      ==
    
       
    
      true
    
      ) 
    
      //
    
      验证过的用户才进行role的处理
    
       
    
       { FormsIdentity Id 
    
      =
    
       (FormsIdentity)Ctx.User.Identity ; FormsAuthenticationTicket Ticket 
    
      =
    
       Id.Ticket ; 
    
      //
    
      取得身份验证票
    
       
    
       
    
      string
    
      [] Roles 
    
      =
    
       Ticket.UserData.Split (
    
      '
    
      ,
    
      '
    
      ) ; 
    
      //
    
      将身份验证票中的role数据转成字符串数组
    
       
    
       Ctx.User 
    
      =
    
       
    
      new
    
       GenericPrincipal (Id, Roles) ; 
    
      //
    
      将原有的Identity加上角色信息新建一个GenericPrincipal表示当前用户,这样当前用户就拥有了role信息
    
       
    
       } }
