I wrote a little python app which will stop and create broadcast via the Youtube API at defined times.
It works all fine but the token created at the first start or when a token does not exists when the app is started gets expired after a few days.
A refresh token is included but after a few days it fails to refresh the token.
I would like to only have to login once and just allow a refresh of the token.
Here is my login function
SCOPES = [";]
...
...
def _authenticate(self, create_new_token: bool = False):
try:
credentials = None
dirname = os.path.dirname(__file__)
token_filename = os.path.join(dirname, self.TOKEN_FILE)
if os.path.exists(token_filename): # do we have a token file already?
credentials = Credentials.from_authorized_user_file(
token_filename, self.SCOPES
)
if create_new_token:
credentials = None # will force to have to login again and create a new token file
if (
not credentials or not credentials.valid
): # do we have no token or is the token no longer valid?
if (
credentials and credentials.expired and credentials.refresh_token
): # is the token expired?
try:
self.logger.debug("Token expired. Attempting to refresh...")
credentials.refresh(Request())
self.logger.debug("Token successfully refreshed.")
except Exception as e:
self.logger.error(f"Error renewing token: {e}")
raise e
else:
try:
dirname = os.path.dirname(__file__)
filename = os.path.join(
dirname,
self.config[self.CONF_YOUTUBE_SETTINGS][
self.CONF_CREDENTIALS_FILE
],
)
flow = InstalledAppFlow.from_client_secrets_file(
filename,
self.SCOPES,
)
credentials = flow.run_local_server(
port=0, access_type="offline", prompt="consent"
)
except Exception as e:
self.logger.error(
f"Failed to login, maybe the credentials file does not exist? `{filename}` Error was: {e}"
)
raise e
try:
with open(token_filename, "w") as token:
token.write(credentials.to_json())
self.logger.info(
f"Token was successfully written to token file `{token_filename}`"
)
except Exception as e:
self.logger.error(
f"Failed to login, maybe the credentials file does not exist? `{token_filename}` Error was: {e}"
)
raise e
self.youtube = build("youtube", "v3", credentials=credentials)
return self.youtube
except Exception as e:
self.logger.error(f"Failed to authenticate: {str(e)}")
return None
Here are some logs of my python script:
