设置Expires的HttpCookie返回DateTime.MinValue [英] HttpCookie with Expires set returns DateTime.MinValue

问题描述

设置cookie时，我发现有些奇怪...

I'm seeing something of an oddity when setting a cookie...

操作：

string cookieName = "foo";
string cookieValue = "bar";

//Set a cookie in the response, along with the Expires.
this.ControllerContext.HttpContext.Response.Cookies.Add(
  new HttpCookie(cookieName, cookieValue)
  {
    Expires = DateTime.Now.AddHours(1)
  }
);

调试时，我可以看到这个新Cookie的到期时间为一个小时，并且但是，当我查看视图中的cookie时，到期时间就不存在了……

When debugging, I can see that this new cookie has an expiry of one hour in the future, and yet, when I look at the cookie in the view, the expiry isn't there...

视图：

<%= Request.Cookies.Get("foo").Value %>

返回 bar 。

<%= Request.Cookies.Get("foo").Expires %>

返回 01/01/0001 00:00:00

有什么想法吗？！

推荐答案

查看请求-其中不包含到期时间。服务器告诉客户端cookie何时到期。客户端也无需告诉服务器：）

You're looking at the request - which doesn't contain an expiry time. The server tells the client when the cookie should expire; there's no need for the client to tell the server as well :)
