我正在与电报机器人合作。
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。
我的机器人运行正常，当我向机器人发送一些命令时，它会回复预期的方式。我无法理解的是来自“服务器”（谷歌云）的消息。
当我分析它时，我感觉到电报会不断向我的API发送请求，而不是我以前发送的每条消息，而是其中的一些消息。
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。没有人可以发送它，因为可以检查chat_id。
2）为什么有一些带有KeyError的回溯？ 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})
我也不明白，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telegram_notification()下的# proccessing中，我正在请求外部API
答案 0 :(得分：0)
我想我明白了。
问题如下。我已经与telegram_notification()中的外部API建立了连接，并且当我向机器人发送消息后导致请求外部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，但是Telegram继续尝试并发送请求，他们放弃了，在telegram_notification()中我没有得到任何回报。
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，我修复了来自机器人的数十个消息的外部API。
目前，我看到了预期的行为。
