asp.net - 尽管已设置，FormsAuthenticationTicket 的 UserData 属性仍为空

Question

由于某种原因，我的身份验证 cookie 的 UserData 属性为空。这是代码:

var authCookie = FormsAuthentication.GetAuthCookie(userName, rememberUser.Checked);
// Get the FormsAuthenticationTicket out of the encrypted cookie
var ticket = FormsAuthentication.Decrypt(authCookie.Value);
// Create a new FormsAuthenticationTicket that includes our custom User Data
var newTicket = new FormsAuthenticationTicket(ticket.Version, ticket.Name, ticket.IssueDate, ticket.Expiration, ticket.IsPersistent, "userData");
// Update the authCookie's Value to use the encrypted version of newTicket
authCookie.Value = FormsAuthentication.Encrypt(newTicket);
// Manually add the authCookie to the Cookies collection
Response.Cookies.Add(authCookie);
FormsAuthentication.RedirectFromLoginPage(userName, rememberUser.Checked);

这是我尝试访问它的方法:

if (HttpContext.Current.Request.IsAuthenticated )
{
    var authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
    if (authCookie != null)
    {
        var authTicket = FormsAuthentication.Decrypt(authCookie.Value);
        string data = authTicket.UserData;
        // data is empty !!!
    }
}

RedictFromLoginPage 覆盖您的 cookie。删除此行并手动重定向 (Response.Redirect)。
