aiohttp 并发请求被挂起

并发数 10，偶数请求立即完成，奇数请求被挂起超过 120 秒，是使用方法不对吗？

import asyncio import aiohttp import time async def get(s, i): start = time.time() async with s.get('URL') as r: await r.read() print(i, ': {} s'.format(round(time.time() - start, 2))) async def test(): async with aiohttp.ClientSession() as s: await asyncio.gather(*[get(s, i) for i in range(10)]) if __name__ == "__main__": loop = asyncio.get_event_loop() loop.run_until_complete(test()) 

结果

0 : 0.38 s 8 : 0.4 s 2 : 0.57 s 6 : 0.6 s 4 : 0.6 s 1 : 129.49 s 9 : 129.5 s 3 : 129.52 s 7 : 129.57 s 5 : 129.63 s
