我正在尝试将 Viber 机器人中的消息发送给订阅的用户。我可以获取订阅的用户ID,但是在发送消息时出现500错误。
from flask import Flask, request, Response
from viberbot import Api
from viberbot.api.bot_configuration import BotConfiguration
from viberbot.api.messages.text_message import TextMessage
app = Flask(__name__)
viber = Api(BotConfiguration(
name='PythonSampleBot',
avatar='http://www.clker.com/cliparts/3/m/v/Y/E/V/small-red-apple-hi.png',
auth_token='xxx-xxx-xxx'
))
@app.route('/', methods=['POST'])
def incoming():
user_id = viber.get_account_info()['members'][0]['id']
print(user_id)
viber.send_messages(user_id, [
TextMessage(text="thanks for subscribing!!!!!")
])
return Response(status=200)
if __name__ == "__main__":
context = ('E:\\Docs\\learn_py\\viberbot\\cert.pem',
'E:\\Docs\\learn_py\\viberbot\\key.pem')
app.run(host='0.0.0.0', port=4443, debug=True, ssl_context=context)
请求消息发送代码:
import json
import requests
webhook_url = 'https://xxx.xxx.xxx.xxx:4443'
requests.post(
webhook_url, data=json.dumps({"text": "Hello World"}),
headers={'Content-Type': 'application/json'},
verify='E:\\Docs\\learn_py\\viberbot\\cert.pem'
)
错误消息:

更新:如 mingaleg 所建议,我已将viber.set_webhook('https://xxx.xxx.xxx.xxx:yyyy')
添加到incoming()
函数中,现在又遇到另一个错误:
Exception: failed with status: 1, message: Result[HttpRequest[POST / HTTP/1.1]@2c67393 > HttpResponse[null 0 null]@72391ae] javax.net.ssl.SSLHandshakeException: General SSLEngine problem
证书是根据this answer中的建议生成的:
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365
答案 0 :(得分:2)
您不应该使用自签名证书。
我可以推荐Let's Encrypt服务,这是一种便捷,免费的方式来为您的域获取SSL证书。
答案 1 :(得分:1)
由于您收到一条webhookNotSet
错误消息,因此应将您的漫游器配置为拥有一个:
...
viber = Api(BotConfiguration(
name='PythonSampleBot',
avatar='http://www.clker.com/cliparts/3/m/v/Y/E/V/small-red-apple-hi.png',
auth_token='xxx-xxx-xxx'
))
viber.set_webhook(webhook_url)
...
webhook_url
应该是烧瓶服务器可以访问的服务器。
