在 Google Compute Engine 上部署 Telegram 聊天机器人以及有关 webhook url 设置的问题

Question

我正在 Google Compute Engine 上部署我的 Telegram 聊天机器人，但遇到了 webhook url 的设置问题。

我有一个 config.ini 来存储相关信息，我试图用项目的 url 进行设置：

[TELEGRAM]
ACCESS_TOKEN = {token}
WEBHOOK_URL = https://api.telegram.org/bot{token}/setWebhook?url=https://{project-id}.appspot.com/hook

我在 GCP 中将防火墙设置为 5000。我复制并粘贴链接，它显示“{“ok”：true，“result”：true，“description”：“Webhook 已设置”}”。但是当我运行我的 main.py（聊天机器人脚本）时，聊天机器人不起作用。 WEBHOOK_URL 应该是什么？部署的步骤是什么 - 是否与我使用 ngrok 复制并粘贴链接以确认挂钩然后运行 ​​main.py 相同？

当我运行 main.py 时，它显示我在开发服务器中，并建议我应该使用生产 WSGI。必须这样做吗？这是日志：

sys:1: TelegramDeprecationWarning: Old Handler API is deprecated - see https://git.io/fxJuV for details
* Serving Flask app "main" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.

我不认为这是我的 main.py，但以防万一我把相关部分放在这里：

import configparser
import requests
import logging
import telegram
from flask import Flask, request
from telegram.ext import Dispatcher, MessageHandler, Filters, Updater, CommandHandler

# Load data from config.ini file
config = configparser.ConfigParser()
config.read('config.ini')

# Enable logging
logging.basicConfig(format = '%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                level = logging.INFO)
logger = logging.getLogger(__name__)

# Initial Flask app
app = Flask(__name__)

# Initial bot by Telegram access token
bot = telegram.Bot(token = (config['TELEGRAM']['ACCESS_TOKEN']))

@app.route('/hook', methods=['POST'])
def webhook_handler():
    """Set route /hook with POST method will trigger this method."""
    if request.method == "POST":
        update = telegram.Update.de_json(request.get_json(force = True), bot)

        # Update dispatcher process that handler to process this message
        dispatcher.process_update(update)
    return 'ok', 200

def whatever_chatbot_function():
    .
    .
    .

dispatcher = Dispatcher(bot, None)

dispatcher.add_handler(CommandHandler('start', start_handler))
    .
    .
    .
if __name__ == "__main__":
    # Running server
    app.run(debug=True)

非常感谢！

不妨试试这个：

def whatever_chatbot_function():
    updater = Updater(bot,use_context=True)
    dp = updater.dispatcher
    dp.add_handler(CommandHandler('start', start_handler))
