我正在使用电报机器人。
我在BotFather中注册了我的机器人，并在Google Cloud上建立了“服务器”，并设置了webHook。
我的机器人正常工作，当我向机器人发送一些命令时，它会以预期的方式答复。我无法理解的是来自“服务器”（Google云）的消息。
当我分析它时，我感觉到电报不断向我的API发送请求，而不是我以前发送的每条消息，而是其中的一些。
这是日志：

如您所见，有些消息发送无数次，有时请求只是丢弃，而我收到了Traceback KeyError。
我不了解这种行为。
1）为什么我收到一些相同的消息？我自己没有将其发送给我的机器人。由于可以检查chat_id，因此没有其他人可以发送。
2）为什么有一些KeyError的Traceback？根据API电报文档，我认为Webhook仅在某些用户发送消息时才允许发送请求？这就像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})
# structure of data
# {'update_id': <int>,
# 'message':
# {'message_id': 138,
# 'from':
# {'id': <int>,
# 'is_bot': False,
# 'first_name': '<str>',
# 'language_code': 'ru'},
# 'chat':
# {'id': <int>,
# 'first_name': '<str>',
# 'type': 'private'},
# 'date': 1556302822,
# 'text': 'hi'}
# }
# print(data)
chat_id = data['message']['chat']['id']
text = data['message']['text']
if chat_id == <int>:
# processing
return jsonify({'success': True})
另外，我不明白，为什么当我删除Webhook然后再次设置它，然后重新启动“服务器”时，我立即收到了来自我的机器人的许多消息。
编辑一个
在我telegram_notification()的部分中，# proccessing我请求外部API
我想我明白了。
问题如下。我与中的外部API关联telegram_notification()，当我向机器人发送消息，然后导致请求外部API时，我期望得到响应，但是外部API有时返回500错误或404错误，并且请求被丢弃。
我以为Telegram经过合理的尝试次数后就放弃了，并停止了请求我的Google Cloud Server，但Telegram继续尝试并发送请求，但这些请求都掉了，我一无所获telegram_notification()。因此，我得到了KeyError和Telegram不断向服务器发送请求，直到服务器正确响应为止。
现在，我修复了外部API，我从机器人那里收到了数十条消息。
目前，我看到了预期的行为。
