我使用 aiohttp
来请求网址 . 大部分时间它正常运行,但有时它会停止而不会引发任何异常 .
正如您在代码中看到的,我捕获了所有异常,但是当它停止时,不会打印异常日志 .
日志看起来像:
get_live_league_games: while True
try
yield from aiohttp.request
但' res = yield from r.json()
'不会打印,它会停止并且不会抛出任何异常 .
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)

这可能是由于互联网性质 - 连接可能会在断开连接错误引发之前的很长一段时间内发生 .
这就是为什么你通常需要超时的客户端http操作 .
我建议将
aiohttp.request()
召唤到asyncio.wait_for
.
