Telegram Bot API Client

A telegram bot API client is written in python 3.5+ and currently compatible with Telegram Bot API 5.3 and later. The reason for writing this bot utility is that I wish to run multi telegram bots which could have same or different business logic (route policy) in one process. I reckon it is lightweight, fast, full implement and only urllib3 dependent.

Quick to go

This is a simple echo bot.

from telegrambotclient import bot_client
from telegrambotclient.base import MessageField, ParseMode

# define a default router named "default"
router = bot_client.router()

# decorate a handler callback on incoming message updates that have a text field
@router.message_handler(MessageField.TEXT)
def on_text_message(bot, message):
    # receive and reply
    sent_message = bot.send_message(
	        chat_id=message.chat.id,
	        text="I receive: <strong>{0}</strong>".format(message.text),
	        parse_mode=ParseMode.HTML,
	    )
    # pin the sent message
    bot.pin_chat_message(chat_id=message.chat.id, message_id=sent_message.message_id)
    return bot.stop_call

# define a callback for incoming updates
async def on_update(bot, update):
    await router.dispatch(bot, update)

# define a bot
bot = bot_client.create_bot(token=<BOT_TOKEN>)
# delete webhook if did or not
bot.delete_webhook(drop_pending_updates=True)
# run polling to fetch updates in every 10s
bot.run_polling(on_update, timeout=10)

Call telegram bot APIs

telegrambotclient has same parameter signatures with the official Telegram Bot APIs. Please see official Telegram Bot API document when calling telegram bot APIs.

Quick to reply

For send_message api, it provides a shortcut.

sent_message = bot.reply_message(
        message,
        text="I receive: <strong>{0}</strong>".format(message.text),
        parse_mode=ParseMode.HTML,
    )

Serving on webhook

In my case, I use fastapi and uvicron to provide a HTTP interface to receive updates from the official Telegram Bot Server. For development and testing, ngrok give a HTTPs URL on my localhost server with a real-time HTTP traffic tunnel.

# run in terminal and get a https tunnel on port 8000 in Austrlia
ngrok http 8000 --region=au

source code:

from fastapi import FastAPI, Request, status
from telegrambotclient import bot_client
from telegrambotclient.base import MessageField, ParseMode
	# from ngrok's https url, replace it with yours
WEBHOOK_URL = "https://5f9d0f13b9fb.au.ngrok.io/bot/{0}"

bot_token = "<BOT_TOKEN>"
	# define a router
router = bot_client.router()
@router.message_handler(MessageField.TEXT)
def on_text_message(bot, message):
    bot.reply_message(message, text="I receive: <strong>{0}</strong> from bot1".format(message.text), parse_mode=ParseMode.HTML)
    return bot.stop_call

app = FastAPI()

# waiting for incoming updates and dispatch them
@app.post("/bot/{bot_token}", status_code=status.HTTP_200_OK)
async def process_telegram_update(bot_token: str, request: Request):
    bot = bot_client.bots.get(bot_token, None)
    if bot:
	await router.dispatch(bot, TelegramObject(**await request.json()))
    return "OK"

bot = bot_client.create_bot(token=bot_token)
bot.setup_webhook(WEBHOOK_URL.format(bot_token))

Serving with multi bots and routers on webhook

from fastapi import FastAPI, Request, status
from telegrambotclient import bot_client
from telegrambotclient.base import Message, MessageField, ParseMode
# from ngrok's https url, replace it with yours
WEBHOOK_URL = "https://5f9d0f13b9fb.au.ngrok.io/bot/{0}"

bot_token_1 = "<BOT_TOKEN_1>"
bot_token_2 = "<BOT_TOKEN_2>"

	# define 2 default routers
router1 = bot_client.router(bot_token_1)
router2 = bot_client.router(bot_token_2)

# bind a handler on router1
@router1.message_handler(MessageField.TEXT)
def on_router1_message(bot, message):
    bot.reply_message(
        message,
        text="I receive: <strong>{0}</strong> from router1".format(message.text),
        parse_mode=ParseMode.HTML,
    )

# bind a handler on router2
@router2.message_handler(MessageField.TEXT)
def on_router2_message(bot, message):
    bot.reply_message(
        message,
        text="I receive: <strong>{0}</strong> from router2".format(message.text),
        parse_mode=ParseMode.HTML,
    )

app = FastAPI()

# waiting for incoming updates and dispatch them
@app.post("/bot/{bot_token}", status_code=status.HTTP_200_OK)
async def serve_update(bot_token: str, request: Request):
    bot = bot_client.bots.get(bot_token, None)
    if bot:
	router = bot_client.routers.get(bot_token, None)
	if router:
  	    await router.dispatch(bot, TelegramObject(**await request.json()))
    return "OK"

bot1 = bot_client.create_bot(token=bot_token_1)
bot1.setup_webhook(WEBHOOK_URL.format(bot_token_1))

bot2 = bot_client.create_bot(token=bot_token_2)
bot2.setup_webhook(WEBHOOK_URL.format(bot_token_2))

Register handlers

decorator

@router.message_handler(MessageField.TEXT)
def on_message(bot, message):
	pass

function

a good way to register one callback on multi routers

def on_message(bot, message):
    pass

router1.register_message_handler(on_message, MessageField.TEXT)
router2.register_message_handler(on_message, MessageField.TEXT)

serve for multi message fields

# callback for a animation message that includes 'animation' AND 'document' fields
@router.message_handler(MessageField.ANIMATION, MessageField.DOCUMENT)
def on_animation(bot, message: Message):
    pass
