的FormsAuthenticationTicket的财产的UserData是，尽管被设置为空 [英] UserData property of FormsAuthenticationTicket is empty despite being set

问题描述

由于某些原因，我在我的身份验证cookie的财产的UserData是空的。这里是code：

  VAR authCookie = FormsAuthentication.GetAuthCookie（用户名，rememberUser.Checked）;
//获取的FormsAuthenticationTicket了加密的cookie
VAR票= FormsAuthentication.Decrypt（authCookie.Value）;
//创建一个新的FormsAuthenticationTicket，包括我们的自定义用户数据
VAR newTicket =新的FormsAuthenticationTicket（ticket.Version，ticket.Name，ticket.IssueDate，ticket.Expiration，ticket.IsPersistent，用户数据）;
//更新authCookie的价值使用newTicket的加密版本
authCookie.Value = FormsAuthentication.Encrypt（newTicket）;
//手动authCookie添加到Cookies集合
Response.Cookies.Add（authCookie）;
FormsAuthentication.RedirectFromLoginPage（用户名，rememberUser.Checked）;
 

下面是我尝试访问它：

 如果（HttpContext.Current.Request.IsAuthenticated）
{
    VAR authCookie = HttpContext.Current.Request.Cookies [FormsAuthentication.FormsCookieName]
    如果（authCookie！= NULL）
    {
        VAR authTicket = FormsAuthentication.Decrypt（authCookie.Value）;
        字符串数据= authTicket.UserData;
        //数据是空的！
    }
}
 

解决方案

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

For some reason, I the UserData property of my authentication cookie is empty. Here is the code:

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);

Here is how I try to access it:

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 !!!
    }
}

解决方案

RedictFromLoginPage overwrites your cookie. Remove this line and redirect manually (Response.Redirect).
