FEATURE: Have ability to run pcloud on headless server/terminal

[ikwyl6]

Tried pcloud using oauth, which works fine, but then the API is looking for a firefox browser or similar on a desktop/GUI. The script should be able to run within console/terminal (headless server). See output below:

You can use username/password authentication (see https://github.com/tomgross/pycloud#usage-of-api) instead of OAuth 2.0 authentication.
OAuth 2.0 is designed to include a web page in its flow (see https://docs.pcloud.com/methods/oauth_2.0/authorize.html).

What you can try is to generate an access token somehow and pass it to PyCloud directly. As documented, the access token currently will not expire (see https://docs.pcloud.com/methods/oauth_2.0/)

>>> access_token = "..."
>>> pc = PyCloud("", access_token, oauth2=True)

Is there a way to get the browser redirect address and then the user can plug that into a webbrowser? Then take the token code and paste it back into the script on the command line and then it gets the access_token that way? That is how some of the other cloud-type scripts work to gain access via command line.

I've been looking at your code and would you entertain a PR that would give the user the ability to run this on a headless server, the script outputs the link to input into a browser (laptop) and then the access token that is returned from the request_uri can be pasted back into a users script of pycloud that authenicates them...? This is done this way in a few different scripts I've seen that interacts with box.com, dropbox, etc, but on a headless server and you do any webbrowsing interaction on another computer (laptop/desktop)...

Hi to use a headless-type server..I've created a script that includes a TokenHandler class in the same file as my script but when I pass my TokenHandler into PyCloud.oauth2_authorize like so:

class TokenHandler:
    redirect_url = "localhost"

    def __init__(self, client_id):
        self._id = client_id
        self.auth_url = f"https://my.pcloud.com/oauth2/authorize?response_type=code&redirect_uri={self.redirect_url}&client_id={self._id}"
        #print(self.auth_url)

    def get_access_token(self):
        print("Copy url into browser: {0}".format(self.auth_url))
        access_token = input("\nCopy/paste the 'code' portion of the link in address bar here: ")
        return access_token, "localhost"

th = TokenHandler(client_id)

pc = PyCloud.oauth2_authorize(client_id=client_id,
        client_secret=client_secret, tokenhandler=th)

I get a

File "/home/alarm/.local/lib/python3.10/site-packages/pcloud/api.py", line 114, in oauth2_authorize
code, hostname = tokenhandler(client_id).get_access_token()
TypeError: 'TokenHandler' object is not callable

I know this might be more of a python-type question, but I thought you may be able to help me out faster as I don't have the most experience with python and classes, etc.

[ikwyl6]

In order for the user to create their own TokenHandler class, I think you need to make the endpoint var available to pass into oauth2_authorize as a variable so the headless server can set endpoint.

[ikwyl6]

you can disregard the above two comments. I figured out after.
