ASP.NET MVC4 Forms 登录验证

Web.config配置:

在<system.web>节下:

<authentication mode="Forms">
  forms loginUrl="~/Auth/Account/Login" timeout="2880" />
</authentication>

登录代码:

/// <summary>
/// 登录
</summary>
public static bool Login(string userName,string userPwd)
{
    MySqlHelper dbHelper = new MySqlHelper();
    sys_user userModel = dbHelper.FindBySql<sys_user>(string.Format("select * from Sys_User where UserName='{0}'",userName));
    if (userModel != null)
    {
        if (userModel.userPwd.ToUpper() == MD5Helper.Encrypt(userPwd))
        {
            FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(userName,1)">false,120);
            string encryptedTicket = FormsAuthentication.Encrypt(ticket);
            HttpCookie authCookie =  HttpCookie(FormsAuthentication.FormsCookieName,encryptedTicket);
            HttpContext.Current.Response.Cookies.Add(authCookie);
            return true;
        }
    }
    false;
}
View Code

退出登录代码:

 退出登录
void LoginOut()
{
    FormsAuthentication.SignOut();
}
View Code

判断用户是否登录:

 判断是否登录
bool IsLogin
{
    get
    {
        return HttpContext.Current.User.Identity.IsAuthenticated;
    }
}
View Code

获取登录用户:

 获取登录用户
static sys_user LoginUser
{
    if (HttpContext.Current.User.Identity.IsAuthenticated)
        {
            string cookieName = FormsAuthentication.FormsCookieName;
            HttpCookie authCookie = HttpContext.Current.Request.Cookies[cookieName];
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
            string userName = authTicket.Name;
            MySqlHelper dbHelper =  MySqlHelper();
            return dbHelper.FindBySql<sys_user>(select * from SYS_USER where UserName='{0}';
    }
}
View Code

Action跳过登录验证使用AllowAnonymous:

[AllowAnonymous]
public ActionResult Login()
{
     View();
}
View Code

需要登录验证的Controller使用Authorize,或者加在自己写的ControllerBase上:

[Authorize]
class ControllerBase : Controller
View Code
