Viber Bot 不启动

Question

我运行我的 Viber 机器人通过 gunicorn 和 flask 在服务器上。但是当我做 curl 请求时我得到错误

* 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 url 我的网站时，我有

Method Not Allowed

The method is not allowed for the requested URL.

app.py

from flask import Flask, request, Response

from viberbot import Api
from viberbot.api.bot_configuration import BotConfiguration
from viberbot.api.messages import KeyboardMessage
from viberbot.api.messages.text_message import TextMessage

from viberbot.api.viber_requests import ViberFailedRequest
from viberbot.api.viber_requests import ViberMessageRequest
from viberbot.api.viber_requests import ViberSubscribedRequest

from keyboard import keyboard_menu

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler()
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)

app = Flask(__name__)
viber = Api(BotConfiguration(
    name='name',
    avatar='https://upload.wikimedia.org/wikipedia/commons/9/9a/Gull_portrait_ca_usa.jpg',
    auth_token='token'
))

@app.route('/', methods=['POST'])
def incoming():
    logger.debug("received request. post data: {0}".format(request.get_data()))
    # every viber message is signed, you can verify the signature using this method
    if not viber.verify_signature(request.get_data(), request.headers.get('X-Viber-Content-Signature')):
        return Response(status=403)

    # 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):
        viber.send_messages(viber_request.get_user.id, [
            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)

wsgi.py

from app import app

if __name__ == "__main__":
    app.run()

curl

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？

Answer 1

尝试向该端点发送 POST 请求，就像 Viber 服务器那样，但使用 cURL。所以您将能够看到错误。

或更新根记录器以查看 500 错误的原因。建议像 documentation (see here 中那样配置以获取更多详细信息):

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__)

最后认为：

when I open url my site I have

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 url 时，它会发送 GET 请求，但端点仅接受 POST http 方法。
