使用Python的服务器 - 客户端推送通知(Server-Client push notification with Python)

 我正在构建一个客户端应用程序，它连接到服务器并等待来自服务器的信号做某事（想想聊天应用程序）。 例如：用户1具有客户端1和2，用户2具有客户端3，服务器将消息发送到频道“用户1”，并且仅客户端1和2将具有该消息。 
 
 我知道Websocket和Long-polling，但找不到自托管且易于测试的服务器。 最初我想在潜水之前先做一个概念验证。 
 
 Nginx推送流似乎符合我的需要，我可以创建一个通道，并通知所有客户端连接到该通道，看起来足够好用，但我找不到任何Python客户端实现 
 
 AutoBahn和其他一些Python服务器似乎只创建一个频道和广播。 
 
 有人可以给我一个正确的方向。 

I'm building an client application, which connect to a server and wait for signal from server to do something (think about chat app). For example: user 1 has client 1 and 2, user 2 has client 3, the server would send the message to the channel "user 1" and only client 1 and 2 will have the message. 
 
I know about Websocket and Long-polling, but can't find a server which is self-hosted and easy to test. Initially I want to make a proof-of-concept first before dive in later.
 
Nginx push stream seems to fit my need, I can create a channel, and notify all client connect to that channel, seem good enough to use, but I can't find any Python client implement
 
AutoBahn and some other Python server seem only create one channel and broadcast.
 
Can someone give me a correct direction.
