我想為電報創建一個機器人和一個網路應用程式，我可以從中編輯和存盤所述機器人的命令。當我在 heroku 中部署時會出現問題，因為我無法同時運行機器人和 Web 應用程式。我想我在使用 webhook 時遇到了問題。這是我的代碼。
應用程式
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!!")

任何的想法？
uj5u.com熱心網友回復：
注釋掉 app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))
您將沒有 /home 處理程式，但 webhook 可能會監聽 Heroku 提供的埠
uj5u.com熱心網友回復：
同一個埠上不能有 2 個行程（參見錯誤），并且不能在同一個 Heroku Dyno 上使用 2 個不同的埠。
您可以使用 Flask APP 作為 REST 前端，而不是 Telegram Webhook，您可以使用該polling方法（不需要系結埠）
