Embed Google Docs PDF viewer in IFRAME
When I upload PDF to Google Docs (using Python's gdata library), I get link to the document:
>>> e.GetAlternateLink().href
Out[14]: 'http://docs.google.com/a/my.dom.ain/fileview id=<veery-long-doc-id>&hl=en'
Unfortunately using that link in IFRAME is not working for me because PDF viewer is redirecting to itself, breaking out of IFRAME.
Looking for the solution, I've found this: http://googlesystem.blogspot.com/2009/09/embeddable-google-document-viewer.html - which looks very nice, but I can't find a way to use it with document uploaded to Google Docs. Does somebody know how to do it/if it's at all possible?
Answer
Just for the record - I haven't found any way to force "internal" google google pdf viewer to not go out of the iframe. And as I mentioned in the question, I found this nice standalone viewer: http://googlesystem.blogspot.com/2009/09/embeddable-google-document-viewer.html, that can be used like this:
<iframe src="http://docs.google.com/gview?url=http://infolab.stanford.edu/pub/papers/google.pdf&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>
-- but in order to use it you have to publish your PDF to the outside world. This wouldn't be a bad solution, because published document has unique id that is probably harder to guess than a password to google docs account. Unfortunately, even with hottest Google Docs API version 3 API, there seems to be no way of publishing PDF programatically..
In the end, I went for a mix of: standalone PDF viewer from google and some other web service that allows to programatically upload and publish PDF. A bit half-baked solution, but it works well so far.
