python - heroku 中 webhook telegrambot 和烧瓶的问题

问题描述

我想创建一个用于电报的机器人和一个 Web 应用程序，我可以从中编辑和存储所述机器人的命令。当我在 heroku 中部署时会出现问题，因为我无法同时运行机器人和 Web 应用程序。我认为我在使用 webhook 时遇到了问题。这是我的代码。

应用程序.py

import os
import sys

import telegram
from telegram.ext import Updater, updater
from telegram.ext.commandhandler import CommandHandler
from resources.commands import *
from flask import Flask, render_template, request

token = "Telegram bot token"
heroku_app_name = "Heroku app name"

bot = telegram.Bot(token= token)
app=Flask(__name__)

updater = Updater(bot.token, use_context= True)

@app.route('/home')
def home():
    return render_template('home.html')    

@app.route('/')
def webhook():
    updater.start_webhook(listen="0.0.0.0",
                    port=int(os.environ.get('PORT', 5000)),
                    url_path=token,
                    webhook_url="https://{}.herokuapp.com/{}".format(os.environ.get("HEROKU_APP_NAME"), token))
    return "!", 200

if __name__ == '__main__':
    webhook()
    app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))

dp = updater.dispatcher

dp.add_handler(CommandHandler("hello", hellothere))    

def hellothere(update, context):
    update.message.reply_text("Hello There!!")

解决方案

你不能在同一个端口上有 2 个进程（见错误），你不能在同一个 Heroku Dyno 上使用 2 个不同的端口。

您可以使用 Flask APP 作为 REST 前端，而不是 Telegram Webhook，您可以使用该polling方法（不需要绑定端口）
