python - 无法在 webhook 模式下部署 aiogram python bot

问题描述

我已经尝试过这个脚本，它类似于用于 webhook 部署的aiogram 官方示例。

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)

轮询工作了几秒钟，然后崩溃了。

我已将环境变量设置如下：

TOKEN（来自 BotFather 的令牌），PROJ（Heroku 项目的名称）

AND HEROKU（无价值）

部署后，

我正在寻找使用 webhook 将 aiogram 部署到 heroku 的示例。

通过对上面的代码进行一些调整，这就是

2020-11-26T09:32:27.283413+00:00 app[web.1]: WARNING:aiogram:Updates were skipped successfully.
2020-11-26T09:32:27.283425+00:00 app[web.1]: WARNING:root:Starting webhook

如何解决这个问题？（在heroku中）

与其他一些调整

由于电报正在发送更新，因此 webhook 设置正确。但他们没有被处理。这就是为什么另一个错误来了。

2020-11-26T09:52:48.395734+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=POST path="/webhook/secret_key..." host=radiant-caverns-48683.herokuapp.com

解决方案

感谢@evgfilim1和@AsyncAwait在 aiogram 的电报组上帮助我。

要点：

  1. 在 async def on_startup(): 和 async def on_shutdown(): 需要 dispatcher: Dispatcher

例子：

from aiogram import Dispatcher

async def on_startup(dispatcher: Dispatcher) -> None:

  1. 使用int(os.getenv("PORT"))代替8443

  2. 尝试绑定到0.0.0.0而不是localhost
