iphone - NSHTTPCookieStorage 和 Cookie 过期日期

Question

在我们的 iPhone 应用程序中，我们在服务器通信期间使用两个 cookie。一种是短 session cookie (JSESSION)，另一种是长 session cookie (REMEMBER ME)。如果服务器有响应，它会发送一个短 session cookie，我可以在 NSHTTPCookieStorage 中找到它。

我的问题是此存储如何处理 cookie 的到期日期？因此，如果 cookie 过期，它是否会自动删除该 cookie，如果我在过期后尝试通过其名称从存储中获取该 cookie，我会得到什么吗？还是我必须手动检查过期时间？

Answer 1

My question is how this storage handles the cookie's expiration date?

NSHTTPCookieStorage 将过期日期作为其属性之一存储 NSHTTPCookie 对象。

http://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookie_Class/Reference/Reference.html#//apple_ref/occ/cl/NSHTTPCookie

So if the cookie expires, does it delete that cookie automatically, and if I try to get this cookie by it's name from the storage after expiration, do I get anything? Or do I have to check the expiration manually?

您应该手动检查过期并自行删除 cookie

正如在 http://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookie_Class/Reference/Reference.html#//apple_ref/occ/cl/NSHTTPCookie 中提到的那样

The receiver’s expiration date, or nil if there is no specific expiration date such as in the case of “session-only” cookies. The expiration date is the date when the cookie should be deleted.
