Asyncio + aiohttp Implementing an asynchronous request "problematic"

Import aiohttpimport asyncio@asyncio.coroutinedef fetch_async (URL):    print (URL)    response = yield from Aiohttp.request (' GET ', url)    # data = yield from Response.read ()    # Print (URL, data)    print (URL, response)    response.close () tasks = [Fetch_async (' http://www.cnblogs.com/'), Fetch_async (' http://www.chouti.com/')]event _loop = Asyncio.get_event_loop () results = Event_loop.run_until_complete (Asyncio.gather (*tasks)) Event_loop.close ()

Asyncio + requests complete IO async

Asyncio + requests Complete IO async
