Describe the bug
Trying to set this up the first time on a headless server, and there are no instructions on how to authorize the app if there is no browser available to open.

To Reproduce
Steps to reproduce the behavior:

  1. follow the setup instructions
  2. Run the tool with --url on a drive link
  3. get stack trace as the authorization token is missing and it cannot open a browser

Expected behavior
Handle the exception and ask to copy paste the link, then copy back the authorization token.

Screenshots

Error initializing Google Drive, please check OpenDirectoryDownloader.GoogleDrive.json and/or remove the 'token.json' directory. See readme on Github for more help.

As a workaround, you could try to use X11 so that the browser window is shown on your local machine :)

Hmm, the notification from GitHub was in the spam..

Well, what you can do it follow the steps on another computer, and copy the OpenDirectoryDownloader.GoogleDrive.json file to the server.

Yeah I had/have several ideas for workarounds, but mot applications that require this kind of auth tend to handle this gracefully in the cli. Usually present the URL to copy paste, then wait with a prompt for the token.

Currently there is no option like this, also not for regular desktop users.

Do you have an example of a console application with this technique for al Google services?

Don't have another app currently handy, but have used that workflow for sure before.

Basically instead of trying to open a browser, you can ask the user to copy paste the URL (exposed in the Exception) into a browser, and give a prompt to provide the challenge to be pasted back, then save it.

It looks like there is no way in the Google client to get this URL. We could indeed get it from the exception, which is not a good practice.

But if that would work, it want to redirect to an URL, and if you open the URL on another machine/IP, the localhost server will not be there and it fails.

Otherwise, if we could get some kind of token, I'm not sure if we can use that instead. I haven't found any solution with 30 minutes of Googling.
