Viber机器人无法启动

Question

我通过服务器上的gunicorn和flask运行Viber bot。但是当我做curl请求时，我得到了一个错误

* Curl_http_done: called premature == 0
* Connection #0 to host chatapi.viber.com left intact
{"status":1,"status_message":"Result[HttpRequest[POST / HTTP/1.1]@3f742f36 > HttpResponse[HTTP/1.1 500 INTERNAL SERVER ERROR]@16f0ed02] null","chat_hostname":"SN-CHAT-01_"}

当我打开我的网址我有

}

我做错了什么

尝试向该端点发送POST请求，就像Viber服务器那样，但使用cURL。这样您就可以看到错误

或更新根记录器以查看错误原因。建议像documentation中那样配置它（有关更多详细信息，请参见here）：

from logging.config import dictConfig

dictConfig({
    'version': 1,
    'formatters': {'default': {
        'format': '[%(asctime)s] %(levelname)s in %(module)s: %(message)s',
    }},
    'handlers': {'wsgi': {
        'class': 'logging.StreamHandler',
        'stream': 'ext://flask.logging.wsgi_errors_stream',
        'formatter': 'default'
    }},
    'root': {
        'level': 'INFO',
        'handlers': ['wsgi']
    }
})

app = Flask(__name__)

最后，我想：

when I open url my site I have

Method Not Allowed

The method is not allowed for the requested URL.

这是因为当您在浏览器中打开该url时，它会发送GET请求，但端点只接受POSThttp方法
