Asp.Net的mvc不得注销 [英] Asp.Net Mvc Can Not Log Out

问题描述

下面是我的code登录

Here is My Code To Log In

 var expire = DateTime.Now.AddDays(7);
        // Create a new ticket used for authentication
        var ticket = new FormsAuthenticationTicket(
        1, // Ticket version
        username, // Username to be associated with this ticket
        DateTime.Now, // Date/time issued
        expire, // Date/time to expire
        true, // "true" for a persistent user cookie (could be a checkbox on form)
        roles, // User-data (the roles from this user record in our database)
        FormsAuthentication.FormsCookiePath); // Path cookie is valid for

        // Hash the cookie for transport over the wire
        var hash = FormsAuthentication.Encrypt(ticket);
        var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash) { Expires = expire };

        // Add the cookie to the list for outbound response
        Response.Cookies.Add(cookie);

这是我的code要检查的作用。这是一个自定义模块IHTTP

Here Is My Code To Check The Roles. It is a custom IHTTP Module

 if (HttpContext.Current.User == null) return;
        if (!HttpContext.Current.User.Identity.IsAuthenticated) return;
        if (!(HttpContext.Current.User.Identity is FormsIdentity)) return;

        // Get Forms Identity From Current User
        var id = (FormsIdentity)HttpContext.Current.User.Identity;
        // Get Forms Ticket From Identity object
        var ticket = id.Ticket;
        // Retrieve stored user-data (our roles from db)
        var userData = ticket.UserData;
        var roles = userData.Split(',');
        // Create a new Generic Principal Instance and assign to Current User
        Thread.CurrentPrincipal = HttpContext.Current.User = new GenericPrincipal(id, roles);

下面是我的code注销

Here is my Code To Log Out

FormsAuthentication.SignOut();
        Response.Cookies.Remove(FormsAuthentication.FormsCookieName);
        Session.Clear(); 
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
        Response.Cache.SetNoStore();
        Response.AppendHeader("Pragma", "no-cache");
        return View("SignIn");

这是疯了。我有两个秃斑了。

This is crazy. I have two bald spots now.

推荐答案

1）不宜您的来电Response.Cookies.Remove（FormsAuthentication.FormsCookieName）;是Response.Cookies.Remove（无论-的用户名不变化）;

1) shouldn't your call to Response.Cookies.Remove(FormsAuthentication.FormsCookieName); be Response.Cookies.Remove(whatever-the-user-name-is);?

2）尝试发送一个过期的cookie回浏览器。

2) try sending an expired cookie back to the browser.

FormsAuthentication.SignOut();

// replace with username if this is the wrong cookie name
Response.Cookies.Remove(FormsAuthentication.FormsCookieName);
Session.Clear(); 
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");

// send an expired cookie back to the browser
var ticketExpiration    = DateTime.Now.AddDays(-7);
var ticket              = new FormsAuthenticationTicket(
    1, 
    // replace with username if this is the wrong cookie name
    FormsAuthentication.FormsCookieName, 
    DateTime.Now, 
    ticketExpiration, 
    false, 
    String.Empty);
var cookie              = new System.Web.HttpCookie("user")
{
    Expires             = ticketExpiration,
    Value               = FormsAuthentication.Encrypt(ticket),
    HttpOnly            = true
};

Response.Cookies.Add(cookie);

return View("SignIn");
