C# .NET MVC 5:在请求之间丢失cookie

我已经实现了自定义身份验证，但在成功登录后无法检索身份验证cookie

设置cookie：

HttpContext.Current.User = user;
Thread.CurrentPrincipal = user;
string userData = JsonConvert.SerializeObject(user);
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1, user.Handle, DateTime.Now, DateTime.Now.AddMinutes(15), false, userData);
string encTicket = FormsAuthentication.Encrypt(authTicket);
HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
HttpContext.Current.Response.Cookies.Add(faCookie);

HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
    FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
    user = JsonConvert.DeserializeObject<User>(authTicket.UserData);
}

正在检索cookie：

HttpContext.Current.User = user;
Thread.CurrentPrincipal = user;
string userData = JsonConvert.SerializeObject(user);
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1, user.Handle, DateTime.Now, DateTime.Now.AddMinutes(15), false, userData);
string encTicket = FormsAuthentication.Encrypt(authTicket);
HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
HttpContext.Current.Response.Cookies.Add(faCookie);

HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
    FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
    user = JsonConvert.DeserializeObject<User>(authTicket.UserData);
}

HttpCookie authCookie=HttpContext.Current.Request.Cookies[FormsAuthentication.formscookeName]；
if（authCookie！=null）
{
FormsAuthenticationTicket authTicket=FormsAuthentication.Decrypt（authCookie.Value）；
user=JsonConvert.DeserializeObject（authTicket.UserData）；
}

问题是

HttpContext.Current.Request.Cookies

不包含

FormsAuthentication.FormsCookieName

键，并且

authTicket

始终为空。

可能您的cookie立即过期。请使用editthiscookie插件检查您的过期时间。您可以通过此函数使用set cookie

 public static bool SetCookie(string cookieName, object value, int expires)
    {
        try
        {
            HttpCookie cookie_clc = new HttpCookie(cookieName, value.ToString());
            cookie_clc.Expires = DateTime.Now.AddMinutes(expires);
            HttpContext.Current.Response.Cookies.Add(cookie_clc);
            return true;
        }
        catch (Exception)
        {
            return false;
        }

    }
