pip3 install websockets
主要用到的API有：
websockets.connect()
websockets.send()
websockets.recv()

server.py，用于搭建webscocket服务器，在本地8888端口启动，接收到消息后会在原消息前加上I got your message:再返回去。

import asyncio
import websockets


async def echo(websocket, path):
    async for message in websocket:
        message = "I got your message: {}".format(message)
        await websocket.send(message)


asyncio.get_event_loop().run_until_complete(websockets.serve(echo, 'localhost', 8888))
asyncio.get_event_loop().run_forever()

#!/usr/bin/env python
import asyncio
import websockets

async def hello(uri):
    async with websockets.connect(uri) as websocket:
        await websocket.send("hello world")
        print("< HELLO WORLD")
        while True:
            recv_text = await websocket.recv()
            print("> {}".format(recv_text))
asyncio.get_event_loop().run_until_complete(hello('ws://localhost:8888'))

先执行server.py，然后执行client.py，client.py的输出结果如下：

< Hello world!

I got your message: Hello world!
