FormsAuthentication - 处理用户名的更改

Question

我的ASP.NET MVC Web应用程序允许管理员更改自己或其他用户的用户名.

用户通过呼叫登录FormsAuthentication.SetAuthCookie(userName [string], createPersistentCookie [bool]).他们通过电话登出FormsAuthentication.SignOut().我知道在更新用户名后我需要将其签名并重新登录.但是我如何检索现有的价值createPersistentCookie呢？例如,如何在重新签名时保留原来的"记住我"设置？

Answer 1

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
}
