用户数据表,每个用户有一个或者多个权限,用户表如下
userid,roleid,username等
权限枚举如下:
public class CustomEnum
{
[Flags]
/// <summary>
/// 用户角色枚举
/// </summary>
public enum UserRole
{
/// <summary>
/// 游客
/// </summary>
Visitor = 1,
/// <summary>
/// 学生
/// </summary>
Student = 2,
/// <summary>
/// 老师
/// </summary>
///
Teacher = 4,
/// <summary>
/// 家长
/// </summary>
Parents = 8,
/// <summary>
/// 加盟商
/// </summary>
Agents = 16
}
}
为以下对象权限对象赋值
/// <summary>
/// 用户角色
/// </summary>
public static CustomEnum.UserRole UserRole
{
get
{
if (!string.IsNullOrEmpty(SessionAction.ReadSession("xxb_WebUserRole")))
{
return (CustomEnum.UserRole)Enum.Parse(typeof(CustomEnum.UserRole), SessionAction.ReadSession("xxb_WebUserRole"));
}
else
{
return CustomEnum.UserRole.Visitor;
}
}
set
{
System.Web.HttpContext.Current.Session["xxb_WebUserRole"] = (CustomEnum.UserRole)Enum.Parse(typeof(CustomEnum.UserRole), value.ToString());
}
}
用以下语句判断是否属于某种权限,并进行某种操作
if (WebSession.UserRole == CustomEnum.UserRole.Visitor) //如果是普通游客
{
//跳转到登陆页面
filterContext.Result = new RedirectResult("/User/LogOn?ReturnUrl=" + filterContext.HttpContext.Request.Url);
}
else
{
//跳转到权限提醒页面
filterContext.Result = new RedirectResult("/Home/Role?ReturnUrl=" + filterContext.HttpContext.Request.Url);
}
