在Heroku上运行Telethon

Question

I'm trying to make an application which would run permanently (ie send me information every minute to my Telethon account), and figured out the best way to do so would be through hosting it on heroku. I'm also using Flask - and am a beginner in all three tools. This is what I have:

from twx.botapi import TelegramBot, ReplyKeyboardMarkup
from telethon import TelegramClient
from telethon.tl.types.input_peer_chat import InputPeerChat
import time
from flask import Flask, render_template, request, redirect

app = Flask(__name__)
chat_id = 40398****
api_id = '10****'
api_hash = 'bae9b**********************'

client = TelegramClient('ID_1', api_id=api_id, api_hash=api_hash)
client.connect()
chat = InputPeerChat(chat_id)

@app.route('/')
def starting_page():
    global client

    if not client.is_user_authorized():
        client.send_code_request('+1234567890') # this is a phone number

    return render_template('index.html', author=author)
.
.
.
#if __name__ == '__main__': # this seems to run automatically on heroku so I commented it out
#    app.run()

The thing is that this code creates two errors and I don't understand why. 1. telethon.errors.rpc_errors_303.PhoneMigrateError: (PhoneMigrateError(...), 'The phone number a user is tryin use for authorization is associated with DC 4.') 2. telethon.errors.rpc_errors_420.FloodWaitError: (FloodWaitError(...), 'A wait of 68533 seconds is required')

I have no idea how to resolve both of these, especially since the script works when run independently, and through a local server. The problem is when trying to bring in heroku.

Thanks!

Answer 1

I thought this way of running it on Heroku was a bit messy. Instead I've created an AlchemySession so that Telethon stores its data into the Heroku Postgres database.

You can either retrieve the Heroku DATABASE_URL or paste it together yourself and pass that into the AlchemySessionContainer . There was a bug that prevented this from working but that has just been fixed.
