Python aiohttp请求已停止,但未引发异常

我使用 aiohttp 以请求url。大多数时候,它正常运行,但有时会停止运行,而不会引发任何异常。

正如您在代码中看到的,我捕获所有异常,但当它停止时,不会打印异常日志。

日志如下所示:

get_live_league_games: while True
try
yield from aiohttp.request

但是 res = yield from r.json() '不打印,它停止并且不抛出任何异常。

while True:
    print('get_live_league_games: while True')
    start = time.clock()
    try:
        print('try')
        r = yield from aiohttp.request('GET',url)
        print('yield from aiohttp.request')
        res = yield from r.json()
        print('res = yield from r.json()')
    except aiohttp.errors.DisconnectedError as e:
        logging.warning('get_live_league_games:',e)
        yield from asyncio.sleep(10)
        continue
    except aiohttp.errors.ClientError as e:
        logging.warning('get_live_league_games:',e)
        yield from asyncio.sleep(10)
        continue
    except aiohttp.errors.HttpProcessingError as e:
         logging.warning('get_live_league_games:',e)
         yield from asyncio.sleep(10)
         continue
    except Exception as e:
         logging.warning('get_live_league_games,Exception:',e)
         yield from asyncio.sleep(10)
         continue
    print('request internet time : ', time.clock()-start)
    yield from asyncio.sleep(10)
