问题
It looks like recently there has been a slight change on embedding a published google docs presentation.
The url for the iframe embed changed from:
https://docs.google.com/present/embed?id=[doc_id]
To:
https://docs.google.com/presentation/embed?id=[doc_id]
Looks like some old documents still require the old embed url, and the new documents require the new url. So given a doc_id is there a way (using the API) to get the embed url you should be using?
update:
After poking around, it looks like from the revision, the old doc has link tag with rel=http://schemas.google.com/docs/2007#publish, which contains https://docs.google.com/present/embed?id=[doc_id], but on the new doc that value is https://docs.google.com/feeds?xoauth_requestor_id=[user_email].
So the question is can I assume that if the link with rel=http://schemas.google.com/docs/2007#publish contains https://docs.google.com/feeds?xoauth_requestor_id=[user_email] then I need to use this url https://docs.google.com/presentation/embed?id=[doc_id]?
Or is it just that the API didn't include the correct value in the revision? (because I think this just happened quite recently).
回答1:
The embed link has rel="http://schemas.google.com/docs/2007#embed" and URLs might look like https://docs.google.com/presentation/d/PRESENTATION_ID/preview. However, you shouldn't manually build those URLs but instead use the value of the link with rel="http://schemas.google.com/docs/2007#embed".
The xoauth_requestor_id parameter won't be included in the embed link as that is only required when using 2-legged OAuth and impersonating a different user. If that is the authorization mechanism of your choice, you have to add those parameters yourself when adding the auth token.
