页面权限设计思路简析

1、用户对象设计

 1     public class User
 2     {
 3         public string UserName { get; set; }
 4         public string Password { get; set; }
 5         //权限管理
 6         public List<string> Permission { get; private set; }
 7         public bool CheckPermission(string code)
 8         {
 9             if (this.Permission != null && this.Permission.Contains(code))
10             {
11                 return true;
12             }
13             return false;
14         }
15         /// <summary>
16         /// 加入权限
17         /// </summary>
18         /// <param name="code"></param>
19         public void SetPermission(string code)
20         {
21             if (this.Permission == null)
22             {
23                 this.Permission = new List<string>();
24             }
25             this.Permission.Add(code);
26         }
27     }

2、扩展Html.Authorize（扩展方法）

    public static class AuthorizeExtensions
    {
        public static bool IsAuthorized(this HtmlHelper helper, string permissionCode)
        {
            return UserService.GetCurrentUser().CheckPermission(permissionCode);
        }

        public static string Authorize(this string html, string permissionCode)
        {
            if (UserService.GetCurrentUser().CheckPermission(permissionCode);)
            {
                return html;
            }
            else
            {
                return string.Empty;
            }
        }


        public static IHtmlString Authorize(this IHtmlString html, string permissionCode)
        {
            if (UserService.GetCurrentUser().CheckPermission(permissionCode);)
            {
                return html;
            }
            else
            {
                return MvcHtmlString.Empty;
            }
        }
    }

3、用例

1                             @if (Html.IsAuthorized(Utility.AuthConst.IcsonCodeAddVirtualQty))
2                             {
3                                    <a onclick="XX">
4                                         查看</a>
5                             }
