使用通配符更新Google AMP缓存中的多个AMP页面

Question

我知道有一种方法可以通过向AMP Cache URL发送GET请求来更新amp内容，但是我想知道是否有可能通过在缓存URL中使用通配符来清除多个页面的缓存，还是我们必须一次清除一个文档，如果要处理数百万个页面，则可能需要很长时间。

Answer 1

The documentation does not indicate such method. I'm sure you've read that in the Remove AMP Content .

Remove AMP content

Use the "update-ping" mechanism to permanently remove content from the Google AMP Cache after the content has been removed from its origin. For example, to purge content formerly served at https://cdn.ampproject.org/i/s/example.com/favicon.ico , send an update ping request to:

https://cdn.ampproject.org/update-ping/i/s/example.com/favicon.ico . Cached content that no longer exists will eventually get removed from the cache; it's just faster to use "update-ping".

Nowhere does it indicate that you can use wildcards.

Answer 2

It sounds like you just need to put a mechanism in place that will update the cache after a page is updated. Our 8 news sites are feed from a CMS. I added a hook into the publish functionality that calls the "update-ping" api after a story is published or republished to makes sure that the page is cached or that the pages cache is up to date.

When a story is unpublished we clear the AMP cache for that page. If we did this by hand it would be a nightmare. Try to tie it into the existing work flow your sites have for updating content. Much more maintainable that way.

Hope this helps!
