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()
