The used file is placed in here (excluding authentication related files) Basically, I made it for my relatives to enjoy.

Thing you want to do

Send a message on discord
The bot searches for song files from google drive
If found, download and play with voice

Also, there are two personal requirements for music bots,

――You can request songs as you like other than yourself --I want to keep the bot running

I decided to use google drive and heroku to meet these requirements.

environment

macOS Mojave 10.14.6
Docker 19.03.5
discord.py 1.3.0
Google Drive API v3

Directory structure

Description of each file

--citron.py: bot body --commands.py: List of commands that the bot responds to --client_secrets.json, token.pickle: google drive authentication related --Procfile, runtime.txt, requirements.txt: Required for Heroku deployment

Test environment construction (Docker container)

docker pull python:3.7
docker images
#Container creation
docker run -d -it --name python --mount type=bind,source=path/to/mydir,target=/home/ python:3.7

#Enter the container
docker exec -it python bash

#The following operations in the container
python3 -m pip install -U discord.py
pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
apt update
apt -y upgrade
apt install ffmpeg

I installed what I needed as needed, and finally it became like this. I don't care though it may contain unnecessary things.

Where it gets stuck

After that, I wrote it steadily while looking at the official document, but since it was clogged with google drive authentication, I will post only the changes.

#Change before
creds = flow.run_local_server(port=0)

#After change
creds = flow.run_console()

I wondered if it was related to testing with Docker or something related to the network, but I could not solve it and it ended up being after the change. If anyone knows, please let me know.
