Viber Bot 无法启动

Question

我通过服务器上的gunicorn 和flask 运行我的Viber 机器人。但是当我提出curl 请求时，我得到了错误

* 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_"}

当我打开我的网站的网址时

Method Not Allowed

The method is not allowed for the requested URL.

    # this library supplies a simple way to receive a request object
    viber_request = viber.parse_request(request.get_data())

    if isinstance(viber_request, ViberMessageRequest):
        message = TextMessage(text="test", keyboard=keyboard_menu)
        # lets echo back
        viber.send_messages(viber_request.sender.id, [
            message
        ])

    elif isinstance(viber_request, ViberSubscribedRequest):

            TextMessage(text="thanks for subscribing!")
        ])
    elif isinstance(viber_request, ViberFailedRequest):
        logger.warn("client failed receiving message. failure: {0}".format(viber_request))

    return Response(status=200)

卷曲

curl -# -i -g -H "X-Viber-Auth-Token:token" -d @viber.json -X POST https://chatapi.viber.com/pa/set_webhook -v

viber.json

{
  "url": "https://my.site.com"
}

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。这样你就能看到错误了。

或更新根记录器以查看 500 错误的原因。建议像documentation 一样配置它（更多细节请参见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__)

最后的想法：

当我打开我的网站的网址时，我有

Method Not Allowed

The method is not allowed for the requested URL.

那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 POST http 方法。
