实现CustomRoleProvider并在MVC3 asp.net中使用该角色进行授权

我一直在学习如何从一些教程中实现CustomRoleProvider,并设法实现以下两种主要方法

    public override string[] GetRolesForUser(string userName)
    {
        string connectionString =
          ConfigurationManager.ConnectionStrings["myDb"].ConnectionString;
        DataContext context = new DataContext(connectionString);
        Table<UserObj> usersTable = context.GetTable<UserObj>();
        UserObj userObj = usersTable.SingleOrDefault(u => u.UserName == userName);
        string roleId = userObj.UserRoleID;

        if (roleId != null)
            return roleId.Select(c => c.ToString()).ToArray();
        else
            return new string[] { }; 

    }

    public override bool IsUserInRole(string userName, string roleName)
    {
        string connectionString =
         ConfigurationManager.ConnectionStrings["myDb"].ConnectionString;
        DataContext context = new DataContext(connectionString);
        Table<UserObj> usersTable = context.GetTable<UserObj>();
        UserObj userObj = usersTable.SingleOrDefault(u => u.UserName == userName);

        if (userObj != null)
        {
            string roleId = userObj.UserRoleID;
            if (roleId.Equals(roleName))
                return true;
        }
       return false;
    }

然后我在控制器的索引方法上添加了[Authorize(Roles =“admin”)],我只想让admin获得访问权限。当我尝试访问该页面时,它似乎执行了限制,例如,如果我输入了url:

       http://localhost:60353/module

..它将我重定向到

        http://localhost:60353/Account/LogOn?ReturnUrl=%2fmodule

但是,似乎没有检查这个角色。

我在这里做错了什么?

答案 0 :(得分:0)

我也面临同样的问题,但我可以调用CustomProvider方法:

  

IsUserInRoles()

显式,但它似乎是正确的,因为可访问性没有改变....它总是重定向到登录屏幕.......
