此外，asyncio还可以创建一个tcp、udp的服务器模型，参见官网连接：https://docs.python.org/zh-cn/3.7/library/asyncio-stream.html
创建http协议的服务器模型的话，需要aiohttp模块，参见aiohttp官网：https://aiohttp.readthedocs.io/en/stable/
官网例子：
服务端：
from aiohttp import web
async def handle(request):
name = request.match_info.get('name', "Anonymous")
text = "Hello, " + name
return web.Response(text=text)
app = web.Application()
app.add_routes([web.get('/', handle),
web.get('/{name}', handle)])
web.run_app(app)
客户端：
import aiohttp
import asyncio
async def fetch(session, url):
async with session.get(url) as response:
return await response.text()
async def main():
async with aiohttp.ClientSession() as session:
html = await fetch(session, 'http://python.org')
print(html)
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
