问题
Can we do anything to update the AMP CDN to purge specific pages or entire domain cached HTML?
回答1:
You can update the contents of the cache on a URL by URL basis using the update ping mechanism: https://developers.google.com/amp/cache/update-ping
This involves making a GET request to the AMP cache URL for your content.

I tied in the update-ping api call to our CMS when we publish or unpublish a story. So everytime we update or remove a page we call the update-ping API so we can update the page cache or remove the page cache depending on what the user has done. You cannot (as of now, could change in the future) cache or clear the entire cache of an entire domain. No wild cards allowed currently.
Hope this helps.
