Python3.5中的异步HTTP请求写法

Python 3.5增加了对async def and await的支持,同样的异步代码看起来干净了很多,也更易读。

import aiohttp
import asyncio

async def get_status(url, id):
    r = await aiohttp.get(url)
    print(r.status, id)
    r.close()


tasks = []
for i in range(100):
    tasks.append(asyncio.ensure_future(get_status('https://api.github.com/events', id=i)))


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(asyncio.wait(tasks))
    loop.close()
