我正在尝试实现一个Web应用程序项目,我的网页可以使用AJAX检查服务器的身份验证票证到期日期/时间.

我正在使用带有slidingExpiration的表单身份验证.

我遇到的问题是我无法弄清楚如何检查值而不重置它.我创建了一个简单的页面 - CheckExpiration.aspx - 下面是代码背后的代码:

  private class AjaxResponse
  {
     public bool success;
     public string message;
     public string expirationDateTime;
     public string secondsRemaining;
     public string issueDate;
  }

  protected void Page_Load(object sender, EventArgs e)
  {
     AjaxResponse ar = new AjaxResponse();
     JavaScriptSerializer js = new JavaScriptSerializer();

     if (HttpContext.Current.User.Identity.IsAuthenticated)
     {
        FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
        string expiration = id.Ticket.Expiration.ToString();

        TimeSpan timeRemaining = id.Ticket.Expiration - DateTime.Now;

        ar.success = true;
        ar.expirationDateTime = expiration;
        ar.issueDate = id.Ticket.IssueDate.ToString();
        ar.secondsRemaining = timeRemaining.Minutes.ToString() + ":" + timeRemaining.Seconds.ToString();
     }
     else
     { …
