data-horde / gdrivac Goto Github PK

Saving accessed URLs is a good way to reduce duplicates on one hand, but on the other it increases the memory burden significantly. What to do?

After running this program on my list of links only a very small amount (only 3 google docs files) were added to the recent tab on google drive. I experimented a bit with gdrive and to add a file to the recent tab I had to send a http put request to
https://clients6.google.com/drive/v2internal/files/{FILE_ID}?fields=id%2Ckind,lastViewedByMeDate&modifiedDateBehavior=NO_CHANGE&supportsTeamDrives=true&enforceSingleParent=true&key={SOME_KEY}
with the additional SAPISID and APISID cookies, and the Authorization and Origin headers. This method seems to work with files, I haven't tested it on folders.

To "simulate" a log-in to a Google account, it's possible to use 3 session keys:

• SID
• SSID
• HSID

The following is my current understanding of the format the values for these come in:

• SID: 70 alphanumeric upper and lower case characters, with dashes in between followed by a final . That's 71 characters in total.
• SSID: 17 alphabetic upper and lower case characters
• HSID: 17 alphanumeric upper and lower case characters, with underscores.

If these are correct, I will update the interactive instructions to describe the shape of the values for these cookies, and later also add in a session-cookie shape checker, to make sure cookies are valid.

Until then, the DoAError exception can be used to validate cookies. A DoAError (Denial of Access Error) is raised when invalid cookie values are used to access a private file.

I have a MacBook Pro with macOS Catalina (10.15.7) and one module for the script wasn't in the requirements:

• colorama
  After I installed, the help command worked.
  Could you please add it to the requirements file ?

PS: On macOS python and python3 are two separated commands and not using python3 would bring other errors, so it would be better if you write this as an observation in the readme.

Session cookies appear sufficient to access files, my testing on private files has revealed.

What is confusing, however, is that files accessed by gdrivac are not added into "Recent" or "Shared with me" on Google Drive. Would sleeping resolve this? Further investigation is needed.

The current isAccessed and askingForAccount conditions are very easy to dupe, perhaps also passing the URL and checking if the domain is drive.google.com might be a good idea.

docs.google.com etc. would need warnings, since they are not at risk of link rot and also because they would break any "drive.google.com" checking pattern.

Elaboration needed on the lines:

• TODO: EXPLAIN HOW TO CHECK COOKIES
• TODO: EXPLAIN HOW TO EXPORT COOKIES

If you have worked with session cookies before, this tutorial might serve as a nice reference https://github.com/Data-Horde/ytcc-archive/wiki/Setup-Tutorial
