BUG记录 aiohttp.connector.TCPConnector object at 0x000000B83C58D860

• 关于aiohttp异步中出现如下错误

Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x000000B83C58D080>
Unclosed connector
connections: ['[(<aiohttp.client_proto.ResponseHandler object at 0x000000B83C55DB40>, 36265.703)]']
connector: <aiohttp.connector.TCPConnector object at 0x000000B83C58D860>

• 关键位置代码如下

async def main():
    global session
    session = aiohttp.ClientSession()
    task = [asyncio.ensure_future(get_index(_)) for _ in range(1, 1 + 1)]
    results = await asyncio.gather(*task)

• 问题原因

  • 没有关闭session或者没有加await

• 解决办法(代码改为如下)

async def main():
    global session
    session = aiohttp.ClientSession()
    task = [asyncio.ensure_future(get_index(_)) for _ in range(1, 1 + 1)]
    results = await asyncio.gather(*task)
    await session.close()
