Question

我已经在Google和这些论坛上闲逛了一段时间，但似乎找不到解决方法...

我成功地创建了一个可以在Heroku上运行的socket.io应用程序（是的！），并且一切正常，我认为我不需要将源代码发布到实际的应用程序上，因为它可以完美地在多个应用程序上运行计算机等...，它只是通过使用node.js制作socket.io应用程序的标准方式进行设置，并且效果很好...

问题：我正尝试使用python在客户端本地连接到此应用。

为此，我尝试使用简单的socketIO_client库，但是仅基于他们的文档，我就遇到了麻烦，因此在这些论坛上，我找到了以下代码并将其放在自己的程序包中：

...    partial_ratio
...    78
...    83
...    100
...    100
...    100

然后在我的主要python文件中使用它：

import logging
import socketIO_client
from socketIO_client.transports import get_response
from socketIO_client.parsers import get_byte, _read_packet_text, parse_packet_text

from requests.exceptions import ConnectionError
def _new_read_packet_length(content, content_index):
    packet_length_string = ''
    while get_byte(content, content_index) != ord(':'):
        byte = get_byte(content, content_index)
        packet_length_string += chr(byte)
        content_index += 1
    content_index += 1
    try:
        return content_index, int(packet_length_string)
    except Exception as ok:
        print ok

def new_decode_engineIO_content(content):
    content_index = 0
    content_length = len(content)
    while content_index < content_length:
        try:
            content_index, packet_length = _new_read_packet_length(
                content, content_index)
        except IndexError:
            break
        content_index, packet_text = _read_packet_text(
            content, content_index, packet_length)
        engineIO_packet_type, engineIO_packet_data = parse_packet_text(
            packet_text)
        yield engineIO_packet_type, engineIO_packet_data

def new_recv_packet(self):
    params = dict(self._params)
    params['t'] = self._get_timestamp()
    response = get_response(
        self.http_session.get,
        self._http_url,
        params=params,
        **self._kw_get)
    for engineIO_packet in new_decode_engineIO_content(response.content):
        engineIO_packet_type, engineIO_packet_data = engineIO_packet
        yield engineIO_packet_type, engineIO_packet_data
def CobSocket(url, port):
    return socketIO_client.SocketIO(url, port)

setattr(socketIO_client.transports.XHR_PollingTransport, 'recv_packet', new_recv_packet)
logging.basicConfig(level=logging.DEBUG)

因此您可以看到我正在将heroku应用程序URL插入套接字连接（如果我根本不使用heroku就使用localhost，则顺便说一句，上面的脚本实际上可以正常工作，它确实可以很好地连接到node.js套接字服务器，问题仅在于它已上传到Heroku）。

在终端上运行时，我从在终端上运行import cobsockit try: socket = cobsockit.CobSocket("insta-menorah.herokuapp.com/", 39203) socket.emit('welcome', "a new connection is here") socket.wait(seconds=1) except cobsockit.ConnectionError: print "something didn't work out too well"获得的端口号。我还听说，如果要从外部访问它，则需要使用端口80，但是当我这样做时，在终端中出现以下错误：

heroku run printenv -a insta-menorah

所以，我什至没有收到任何错误消息，但是当我运行脚本时，它似乎永远死了，什么也没做，这就是我运行的内容，并且卡住了一段时间：

Starting new HTTP connection (1): insta-menorah.herokuapp.com:80
DEBUG:urllib3.connectionpool:http://insta-menorah.herokuapp.com:80 "GET //socket.io/?EIO=3&transport=polling&t=1543480624168-0 HTTP/1.1" 200 None

  File "/Users/admin/Documents/menorah/cobsockit.py", line 25, in new_decode_engineIO_content
    content, content_index)
TypeError: 'NoneType' object is not iterable

然后大约10到15分钟后，它显示如下：

python socketpython.py
DEBUG:urllib3.connectionpool:Starting new HTTP connection (1): insta-menorah.herokuapp.com:39203

，然后重新开始连接。...

SO：我怎么能简单地使用Python连接到Heroku node.js应用！！

Python socketIO_client连接到Heroku应用程序（在localhost中可以正常工作）
