无法在app.yaml中为python应用程序设置缓存过期 [英] unable to set cache expiration on in app.yaml for a python app

问题描述

在我的GAE应用程序中，我提供的静态内容如下（这些是我的app.yaml文件中的条目）：

In my GAE app I am serving static content as follows (those are my entries in my app.yaml file):

handlers:
- url: /css
  static_dir: static/css
  expiration: "10m"

- url: /js
  static_dir: static/js
  expiration: "10m"

请点击此处： https://developers.google.com/appengine/docs/ python / config / appconfig＃expiration 内容永远不会缓存在浏览器中，无论我使用的是开发服务器还是上传我的应用程序。

Despite the information available here: https://developers.google.com/appengine/docs/python/config/appconfig#expiration the content is never cached in the browser regardless whether I use the dev server or upload my app.

我使用的是Chrome，请求标题是：
$ b

I am using Chrome and the request header is:

cache-control:max-age=0

和响应标题是：
$ b

and the response headers are:

cache-control:no-cache, must-revalidate
pragma:no-cache
server:Google Frontend
status:304 Not Modified

我能够找到的答案，我测试了这两个与登录和进入我的谷歌管理员帐户，并没有改变。

As per some answers I was able to find, I tested this both with being logged in and out into my google admin account and nothing changes.

任何帮助，将不胜感激。非常感谢！

Any help on this would be greatly appreciated. Many thanks!

退出我的管理员帐户时收到的响应标题：

Response headers I get when logged out of my admin account:

date:Fri, 25 Apr 2014 09:54:44 GMT
etag:"lhoIow"
server:Google Frontend
status:304 Not Modified
version:HTTP/1.1

推荐答案

使用 10m 值正常工作。
很可能是因为您使用您的Google管理员帐户登录的。
GAE会为这些帐户返回 no-cache 。
尝试在隐身模式下打开相同页面会返回适当的缓存过期时间。

GAE should work fine with 10m value. Most probably that was because you were signed in with your google admin account. GAE returns no-cache for such accounts. Trying opening the same page in an incognito returns proper cache expiry times.

默认情况下GAE会将缓存设置为10分钟，因此即使您没有设置任何到期 - 您应该看到10分钟而不是无缓存。

By default GAE sets cache to 10 minutes, so even if you didn't set any expiry - you should see 10 minutes instead of no-cache.
