Problem capturing PDF page #19

Closed Kerenok closed 5 years ago

Kerenok commented 5 years ago

Scrapbook can successfully capture PDF pages (for example, https://www.isprs.org/proceedings/XXXVI/5-C53/papers/FPL010.pdf ). In this situation, maybe Scrapbee should just send the raw file to the backend without trying to execute any script on the page (function scriptsAllowed).

Hi, the problem is how we can know the content of a tab is PDF, and how to fetch the PDF, I need to find out if there's an avaliable way.

The reason that It's maybe a response for a POST-request with necessary parameters. or cookies needed, So I need to check/fetch the content currently loaded.

As I know we can not fetch anything about tab content with tab APIs, That's why content script is needed.

Maybe doing a HEAD-request would allow to access the Content-Type of the page and save it accordingly?

This should work, but not for all of the scenarios I think, because response does not always = content, this is true even for common HTML page, the content maybe chaged by js after HTML loaded.

Now I suggest to download the pdf manually, open it with firefox and capture it as a bookmark
