python-3.x - Python 3.6.4 可以在本地连接到 Slack(通过 slackclient)，但在 Azure 中则不能

Question

使用 slackclient 的 Python 3.6.4(32 位 x86)在本地连接到 RTM API，并且能够监听 slack channel 的变化。在 Azure(64 位 AMD)中运行的相同代码不起作用。

我已确保 Azure python 安装尽可能靠近我的本地计算机。存在一些软件包差异(见下文)，但这不应该是问题，因为这些软件包没有被使用:

Azure 与本地计算机
* numpy 1.15.3 与 numpy 1.16.0
* pyodbc 4.0.24 与 pyodbc 4.0.25
* pytz 2018.7 与 pytz 2018.9
* setuptools 38.5.2 与 setuptools 28.8.0

我查看了以下链接，但不确定它们是否有帮助。在 Azure 中设置代理的一些说明不再有效(通过几个步骤)。最近，当我更改了下面的(完全不相关的 Python)设置时，Azure 停止了为我的 Web 应用程序(C#/ASP)提供服务。

Application settings->General settings->Python version (from Off to 3.4)

找回它真的很痛苦。我认为我需要一个代理，尽管我认为 Azure 应该为此提供更好的说明。我在某种程度上是一个 Azure 新手，尽管还不够新，无法随心所欲地改变事物!

make Python 3.x Slack (slackclient) use a corporate proxy

Custom Slack Bot cannot connect

https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/application-proxy-configure-connectors-with-proxy-servers

https://learn.microsoft.com/en-us/azure/azure-functions/functions-proxies

import time, logging, os
from slackclient import SlackClient
from datetime import datetime

def main():
    #proxies = dict(https="proxy.azure.com:443", http="proxy.azure.com:443")
    sc = SlackClient(BOT_TOKEN)
    CHANNEL_ID = "some channel id"
    logger.debug("Listening to channel '{0}' with id '{1}' for the following actions: ".format(CHANNEL_NAME, CHANNEL_ID))

    if sc.rtm_connect():
        logger.debug("Connected to Slack!")

        while True:
            # Read latest messages
            # If activity is in CHANNEL_ID do something

    else:
        logger.debug("Couldn't connect to slack")

在我的本地计算机上，我得到以下内容(我删除了一些代码):

DEBUG - Listening to channel 'news' with id 'CFDQ3BXYZ' for the following actions:
DEBUG - message_replied
DEBUG - message_deleted
DEBUG - message_changed
DEBUG - Connected to Slack!

但是，在 Azure 中，我得到以下信息:

DEBUG - Listening to channel 'news' with id 'CFDQ3BXYZ' for the following actions:
DEBUG - message_replied
DEBUG - message_deleted
DEBUG - message_changed
DEBUG - Couldn't connect to Slack!

Azure错误消息如下:

任何帮助将不胜感激!

看来 WebJobs 仅限于端口 80。因此，至少目前无法在 Azure WebJobs 上打开端口等(请参阅下面的文章/帖子)。因此，虚拟机或其他一些路由似乎是继续的方法。

Can I open ports on Azure Websites?
