I use the Telethon == 1.4.3 in my code:
import telepot
import threading
from telethon import TelegramClient
from flask import Flask, request
from telepot.loop import OrderedWebhook
from telepot.delegate import (
per_chat_id, create_open, pave_event_space, include_callback_query_chat_id)
class Main_Class(telepot.helper.ChatHandler):
def __init__(self, *args, **kwargs):
super(Main_Class, self).__init__(*args, **kwargs)
def on_chat_message(self, msg):
content_type, chat_type, chat_id = telepot.glance(msg)
if content_type == 'text':
client = TelegramClient('session_name', api_id, api_hash)
client.connect()
client.send_message('me', 'Hello World from Telethon!')
app = Flask(__name__)
@app.route('/', methods=['GET', 'POST'])
def pass_update():
webhook.feed(request.data)
return 'OK'
TOKEN = my_token
bot = telepot.DelegatorBot(TOKEN, [
include_callback_query_chat_id(
pave_event_space())(
per_chat_id(types=['private']), create_open, Main_Class, timeout=100000),
])
webhook = OrderedWebhook(bot)
webhook.run_as_thread()
Since I also use the Flask, these two interfere with each other and I got the following error:
RuntimeError: There is no current event loop in thread 'Thread-1'
I imported asyncio and added the following lines to the code and the problem was solved
class Main_Class(telepot.helper.ChatHandler):
......
loop = asyncio.new_event_loop()
client = TelegramClient('session_name', api_id, api_hash,loop=loop)
loop.run_until_complete(goo(loop,client))
loop.close()
.....
async def goo(loop,client):
client.connect()
await client.send_message('me', 'Hello World from Telethon!')
The following error occurs despite the fact that I have already established a connection:
ConnectionError: Cannot send requests while disconnected
