FormsAuthentication - 处理用户名的变化 [英] FormsAuthentication - handling a change of username

问题描述

我的ASP.NET MVC Web应用程序，管理员可以改变自己，或者其他用户的用户名。

用户可以通过调用记录在 FormsAuthentication.SetAuthCookie（用户名[字符串] createPersistentCookie [布尔]）。他们是通过调用注销 FormsAuthentication.SignOut（）。据我所知，在更新后的用户名我需要签署出来，并再次回。但我怎么检索的现有的 createPersistentCookie 的价值？例如我该怎么办保留其原有的记住我设置登录他们回来的时候？

解决方案

  VAR cookieName = FormsAuthentication.FormsCookieName;
VAR请求= HttpContext.Current.Request;
VAR饼干= request.Cookies.Get（cookieName）;
如果（饼干== NULL）
    返回;尝试
{
    VAR票= FormsAuthentication.Decrypt（cookie.Value）;    //这应该给你你想要的...
    布尔isPersistent = ticket.IsPersistent;
}
赶上（异常前）
{
    //记录
}
 

My ASP.NET MVC web application allows administrators to change their own, or other users' usernames.

Users are logged in by calling FormsAuthentication.SetAuthCookie(userName [string], createPersistentCookie [bool]). They are logged out by calling FormsAuthentication.SignOut(). I understand that after updating the username I'd need to sign them out and back in again. But how do I retrieve the existing value of createPersistentCookie? e.g. how do I retain their original 'remember me' setting when signing them back in?

解决方案

var cookieName = FormsAuthentication.FormsCookieName;
var request = HttpContext.Current.Request;
var cookie = request.Cookies.Get(cookieName);
if (cookie == null)
    return;

try
{
    var ticket = FormsAuthentication.Decrypt(cookie.Value);

    //This should give you what you want...
    bool isPersistent = ticket.IsPersistent;
}
catch (Exception ex)
{
    //Logging
}
