Не удается развернуть бот aiogram python в режиме webhook

#python #heroku #telegram #telegram-bot

#python #heroku #telegram #telegram-бот

Вопрос:

Я попробовал этот скрипт, который похож на официальный пример aiogram для развертывания webhook.

 import os
import logging

from aiogram import Bot, Dispatcher, types, executor

PROJECT_NAME = os.environ.get("PROJ")
TOKEN = os.environ.get("TOKEN")

WEBHOOK_HOST = f"https://{PROJECT_NAME}.herokuapp.com"
WEBHOOK_PATH = "/webhook/"   TOKEN
WEBHOOK_URL = f"{WEBHOOK_HOST}{WEBHOOK_PATH}"

WEBAPP_HOST = "localhost"
WEBAPP_PORT = 8443

bot = Bot(TOKEN)
dp = Dispatcher(bot)

logging.basicConfig(level=logging.INFO)


# Example handler
@dp.message_handler(commands="start")
async def start_handler(message: types.Message):
    await bot.send_message(message.chat.id, text="hi")


# Run after startup
async def on_startup():
    await bot.delete_webhook()
    await bot.set_webhook(WEBHOOK_URL)


# Run before shutdown
async def on_shutdown():
    logging.warning("Shutting down..")
    await bot.delete_webhook()
    await dp.storage.close()
    await dp.storage.wait_closed()
    logging.warning("Bot down")


if __name__ == "__main__":
    if "HEROKU" in list(os.environ.keys()):
        executor.start_webhook(
            dispatcher=dp,
            webhook_path=WEBHOOK_PATH,
            on_startup=on_startup,
            on_shutdown=on_shutdown,
            skip_updates=True,
            host=WEBAPP_HOST,
            port=WEBAPP_PORT,
        )
    else:
        executor.start_polling(dp)

Опрос работал нормально в течение нескольких секунд, а затем произошел сбой.

Я установил переменные среды следующим образом:

TOKEN ( токен от BotFather) , PROJ ( название проекта Heroku)

И ( без значения) HEROKU

После развертывания,

Я ищу пример развертывания aiogram в heroku с помощью webhook.

С некоторыми изменениями в приведенном выше коде это произошло

как это исправить? ( в heroku)

с некоторыми другими настройками

webhook настроен правильно, потому что telegram отправляет обновления. но они не обрабатываются. вот почему появляется другая ошибка.

Ответ №1:

Спасибо @evgfilim1 и @AsyncAwait, которые помогли мне в группе aiogram в telegram.

Важные моменты:

  1. При асинхронном определении on_startup(): и асинхронном определении on_shutdown(): нужен диспетчер: Диспетчер

Пример:

 from aiogram import Dispatcher

async def on_startup(dispatcher: Dispatcher) -> None:
  1. Используйте int(os.getenv("PORT")) вместо 8443
  2. Попробуйте привязку к 0.0.0.0 вместо localhost

Вот полный пример развертывания бота aiogram, который использует webhooks для получения обновлений для Heroku
