flask - 启动 Telegram 机器人的问题

Question

我正在尝试在 PythonAnywhere 上部署我的电报机器人。它在免费帐户上运行良好，但在付费帐户上存在一些问题。我在错误日志中收到“OpenSSL.SSL.Error: [('SSL routines', 'ssl3_get_record', 'decryption failed or bad record mac')]”消息(因此 bot 工作错误) .我该如何解决？
我正在使用 python3.7 + pyTelegramBotAPI + flask

错误重现的代码示例:

# coding=utf-8
import telebot
import flask
import time


token = 'bot_token'
bot = telebot.TeleBot(token, threaded=False)

WEBHOOK_HOST = '*userName*.pythonanywhere.com'
WEBHOOK_URL_BASE = "https://%s" % (WEBHOOK_HOST)
WEBHOOK_URL_PATH = "/%s/" % (token)

app = flask.Flask(__name__)

# Process webhook calls
@app.route(WEBHOOK_URL_PATH, methods=['POST'])
def webhook():
    if flask.request.headers.get('content-type') == 'application/json':
        json_string = flask.request.get_data().decode('utf-8')
        update = telebot.types.Update.de_json(json_string)
        bot.process_new_updates([update])
        return ''
    else:
        flask.abort(403)

@bot.message_handler(commands=['start', 'help'])
def handle_start_help(message):
        bot.send_message(message.chat.id, text="Hello, my friend")

bot.remove_webhook()
time.sleep(0.1)
bot.set_webhook(url=WEBHOOK_URL_BASE + WEBHOOK_URL_PATH)

从 pyTelegramBotAPI github 存储库上的一个问题来看，您正在使用的请求版本与您正在使用的 OpenSSL 版本之间似乎不兼容。尝试改用请求 2.10.0。
