ASP.NET Session 不跨页面存储
首先，我创建了一个登录页面，将一个键值对添加到会话中，并验证该页面上的会话是否保存该对。 接下来，我尝试转到另一个页面，在会话中查找该对，但它不在那里。 我已将会话超时设置为 15000，这样就不会超时。 我目前使用静态类 HttpContext.Current.Session 来查看会话。 每个页面都会调用这个静态类来查看会话，但每次会话密钥计数 = 0 时，除非在登录页面上配对之后。
public static class UserAuthenticationManager
{
public static bool IsAuthenticated()
{
UserAuthenticationTicket ticket = ((UserAuthenticationTicket)HttpContext.Current.Session[DefinesPL.UserTicketSessionName]);
string redirectUrl = String.Format(DefinesPL.LoginPage);
if (ticket != null)
{
if (ticket.IsExpired())
{
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Redirect(redirectUrl, true);
}
}
else
{
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Redirect(redirectUrl, true);
}
return true;
}
First, I created a Login page that added a key value pair to the session and verified that on that page the session holds that pair.
Next, I attempt to go to another page that looks for that pair in the session and it is not there. I've put the timeout for the session to 15000 so it won't timeout.
I currently use a static class to look at the session, HttpContext.Current.Session.
Each Page calls this static class to look at the session but every time the session key count = 0 except after I the pair on the login page.
public static class UserAuthenticationManager
{
public static bool IsAuthenticated()
{
UserAuthenticationTicket ticket = ((UserAuthenticationTicket)HttpContext.Current.Session[DefinesPL.UserTicketSessionName]);
string redirectUrl = String.Format(DefinesPL.LoginPage);
if (ticket != null)
{
if (ticket.IsExpired())
{
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Redirect(redirectUrl, true);
}
}
else
{
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Redirect(redirectUrl, true);
}
return true;
}

可能还想确保您已将 Global.asax 添加到您的项目中。 我相信我以前遇到过这个问题，为每个 HTTP 请求创建一个新会话。
Might also want to make sure you have Global.asax added to your project. I believe i ran into this before, where a new session was created for every HTTP request.
最常见的原因是 cookie 被禁用。 您需要需要 Cookie，或切换到无 Cookie 会话模型，这有点难处理。
The most common cause is cookies being disabled. You'll need to require cookies, or switch to a cookieless session model, which is a little harder to work with.
