Telegram 不断向服务器发送请求
Telegram constantly send requests to the server
我正在使用电报机器人。
我在 BotFather 中注册了我的机器人，在 Google Cloud 上建立了 "server"，设置了 webHook。
我的机器人工作正常，当我向我的机器人发送一些命令时，它以预期的方式回复。我无法理解的是来自 'server'（google 云）的消息。
当我分析它时，我有一种感觉，电报不断向我的 API 发送请求，而不是我以前发送的每条消息，但其中一些。

如您所见，有些消息发送无限次，有时请求只是丢弃，我得到一个 Traceback KeyError。
我不明白这种行为。
1) 为什么我会收到一些相同的消息？
我不会自己将它发送给我的机器人。没有其他人可以发送它，因为有 chat_id 的检查。
2) 为什么会出现一些Traceback with KeyError？
我认为，根据 API-telegram 文档，Webhook 只允许在某些用户发送消息时发送请求？这里就像 Telegram 不断向我的服务器发送请求..
@app.route('/telegram_notification', methods=['POST'])
def telegram_notification():
if request.method == "POST":
data = request.get_json()
print(data)
if data is None:
return jsonify({'success': True})

另外，我不明白，为什么当我删除 Webhook 然后重新设置它，然后重新启动我的 'server'，我立即收到来自我的 bot 的几十条消息..

在我的 telegram_notification() 部分下 # proccessing 我请求外部 APIs
我想我明白了。
问题如下。我在 telegram_notification() 中与外部 API 有联系，当我向我的机器人发送消息时，这导致请求外部 API，我期待响应，但外部 APIs 有时 returned 500 错误或 404 错误并且请求被丢弃。
我认为 Telegram 在经过合理次数的尝试后放弃并停止请求我的 Google 云服务器，但 Telegram 继续尝试和发送请求，他们放弃了，我在 return 中什么也没有在 telegram_notification()。
因此，我收到 KeyError，Telegram 不断向服务器发送请求，直到服务器正确响应。
现在我修复了外部 APIs 我从我的机器人那里收到了很多消息。
目前我看到了预期的行为。
