大猩猩会话-如何根据请求自动更新Cookie过期？

问题描述

我知道许多其他语言和网络框架会在每次通过后端访问会话（或类似操作）时自动将cookie的过期时间更新为会话超时。我不相信Gorilla会提供此实用程序。

更新cookie过期的最佳做法是什么，尤其是与大猩猩/围棋有关的最佳做法？

解决方案

如果设置cookie的Max-Age参数，则无需设置Expiry，除非需要支持旧的浏览器

仅使用Max-Age意味着您不需要在每个请求上都进行更新。

设置规范：

I know many other languages and web frameworks will automatically update a cookie's expiration time to the session timeout every time a session is accessed via the backend (or some action like that). I don't believe Gorilla provides this utility.

I am consider just writing some request middleware that, if it detects a valid session, will extend the cookie lifetime but I am wondering if there is a better method of doing this.

What are the best practices for updating cookie expiration, especially as they pertain to Gorilla/Go?

解决方案

If you set the Max-Age parameter of the cookie, you don't need to set Expiry as well, unless you need to support old browsers that don't understand Max-Age.

Using only Max-Age means you don't need to update it on every request.

Set the spec: http://tools.ietf.org/html/rfc6265#section-4.1.2
