Telegram Bot API with Tornado

Telegram Bot API with Tornado.

High Level API Example

BotAgent is a high level undead, you can demand it to send requests:

from tornado import gen, ioloop
from wcpan.telegram import api, types


async def main():
    API_TOKEN = 'your_token'
    lich = api.BotAgent(API_TOKEN)
    talk_to = 42

    # getMe
    user = await lich.get_me()
    print(user)

    # getUpdates
    updates = await lich.get_updates()
    print(updates)

    # sendMessage
    message = await lich.send_message(talk_to, 'hello')
    print(message)

    # sendPhoto
    photo = types.InputFile('path_to_your_phoho.png')
    message = await lich.send_photo(talk_to, photo)
    print(message)

    # sendAudio
    audio = types.InputFile('path_to_your_audio.ogg')
    message = await lich.send_audio(talk_to, audio)
    print(message)

    # sendVideo
    video = types.InputFile('path_to_your_video.mp4')
    message = await lich.send_video(talk_to, video)
    print(message)

    # sendDocument
    document = types.InputFile('path_to_your_file.zip')
    message = await lich.send_document(talk_to, document)
    print(message)


main_loop = ioloop.IOLoop.instance()
main_loop.run_sync(main)

And let it handles updates:

from tornado import gen, ioloop
from wcpan.telegram import api


class KelThuzad(api.BotAgent):

    def __init__(self, api_token):
        super(KelThuzad, self).__init__(api_token)

    async def on_text(self, message):
        id_ = message.message_id
        chat = message.chat
        text = message.text
        # echo same text
        await self.send_message(chat.id_, text, reply_to_message_id=id_)

    async def on_video(self, message):
        chat = message.chat
        video = message.video
        # echo video without upload again
        await self.send_video(chat.id_, video.file_id, reply_to_message_id=id_)


async def forever():
    API_TOKEN = 'your_token'
    lich = api.KelThuzad(API_TOKEN)
    await lich.poll()


main_loop = ioloop.IOLoop.instance()
main_loop.run_sync(forever)

Or handles updates by webhook:

from tornado import gen, ioloop, web
from wcpan.telegram import api


class HookHandler(api.BotHookHandler):

    async def on_text(self, message):
        lich = self.application.settings['lich']
        id_ = message.message_id
        chat = message.chat
        text = message.text
        # echo same text
        await lich.send_message(chat.id_, text, reply_to_message_id=id_)


async def create_lich():
    API_TOKEN = 'your_token'
    lich = api.BotAgent(API_TOKEN)
    await lich.listen('https://your.host/hook')
    return lich


main_loop = ioloop.IOLoop.instance()

lich = main_loop.run_sync(create_lich)
application = web.Application([
    (r"/hook", HookHandler),
], lich=lich)
# please configure your own SSL proxy
application.listen(8000)

main_loop.start()

Low Level API Example

BotClient is also there, which provides simple and direct API mapping:

from tornado import gen, ioloop
from wcpan.telegram import api, types


async def main():
    API_TOKEN = 'your_token'
    ghoul = api.BotClient(API_TOKEN)
    talk_to = 42

    # getMe
    user = await ghoul.get_me()
    print(user)

    # getUpdates
    offset = 0
    updates = []
    while True:
        us = await ghoul.get_updates(offset)
        updates.extend(us)
        if not us:
            break
        offset = us[-1].update_id + 1
    print(updates)

    # sendMessage
    message = await ghoul.send_message(talk_to, 'hello')
    print(message)

    # sendDocument
    document = types.InputFile('path_to_your_file.zip')
    message = await lich.send_document(talk_to, document)
    print(message)


main_loop = ioloop.IOLoop.instance()
main_loop.run_sync(main)
