# ValueError: too many file descriptoersin select()报错问题
# 一般是并发请求数太大导致的，通常通过减少并发数解决。
#
# 我遇到的情况：并发量设置的不高，运行一段时间后报该错误。通过搜索、调试，最后看aiohttp文档时发现是因为请求的https站点的服务器没有正确完成ssl连接，需要指定一个叫enable_cleanup_closed的参数为True：
#
# session = aiohttp.ClientSession(connector=aiohttp.TCPConnector(enable_cleanup_closed=True)
# 官方对enable_cleanup_closed参数的解释：
#
# Some ssl servers do not properly complete SSL shutdown process, in that case asyncio leaks SSL connections.
# If this parameter is set to True, aiohttp additionally aborts underlining transport after 2 seconds. It is off by default.
