django - 在 django 的 asynchttpconsumer 中发送 http 请求？

问题描述

我的 django 项目中有一个 asynchttpconsumer 类，它从外部服务器接收 webhook。在 webhook 请求期间，我想向授权服务器发送 http 请求，获取响应，并使用它来完成 webhook 请求的处理。我遵循了本教程，但扩展了我拥有的代码。https://channels.readthedocs.io/en/latest/topics/consumers.html#asynchttpconsumer

class frontEndConsumer(AsyncHttpConsumer):
    async def http_request(self, request):
        header = self.scope
        print(header)
        # connect to auth server
        conn = http.client.HTTPConnection("https://******.auth0.com", 80)
        headers = { 'authorization': "Bearer *******************" }
        print("request get connection")
        conn.request("GET", "/userinfo", headers=headers)

        res = conn.getresponse()
        data = res.read()
        # do some processing
        print(data.decode("utf-8"))  
        # do other stuff

        await self.http_reply(data)
        return

由于我使用的是身份验证服务 (auth0)，因此我使用他们的示例从这里获取信息：https ://auth0.com/docs/quickstart/backend/python/02-using 但我不断收到 errno -2 “conn.request”行：

Exception inside application: [Errno -2] Name or service not known
  File "/home/jeremy/.local/lib/python3.6/site-packages/channels/consumer.py", line 59, in __call__
    [receive, self.channel_receive], self.dispatch

    await dispatch(result)
  File "/home/jeremy/.local/lib/python3.6/site-packages/channels/consumer.py", line 73, in dispatch
    await handler(message)
  File "/home/jeremy/Documents/APbackend/myapp/webhook.py", line 59, in http_request
    conn.request("GET", "/userinfo", headers=headers)
  File "/usr/lib/python3.6/http/client.py", line 1264, in request
    self._send_request(method, url, body, headers, encode_chunked)
  File "/usr/lib/python3.6/http/client.py", line 1310, in _send_request
    self.endheaders(body, encode_chunked=encode_chunked)
  File "/usr/lib/python3.6/http/client.py", line 1259, in endheaders
    self._send_output(message_body, encode_chunked=encode_chunked)
  File "/usr/lib/python3.6/http/client.py", line 1038, in _send_output
    self.send(msg)
  File "/usr/lib/python3.6/http/client.py", line 976, in send
    self.connect()
  File "/usr/lib/python3.6/http/client.py", line 948, in connect
    (self.host,self.port), self.timeout, self.source_address)
  File "/usr/lib/python3.6/socket.py", line 704, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "/usr/lib/python3.6/socket.py", line 745, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
  [Errno -2] Name or service not known

我找不到对此错误的任何引用，或者这甚至是我正在尝试做的正确方法！

解决方案

弄清楚发生了什么：

我的网址应该没有 https://

在此之后我收到 301 错误

这是由 HTTPConnection 引起的，auth0 不支持 http，只支持 https。所以它需要更改为 HTTPSConnection 并将端口更改为 443。

之后能够让它工作。
