使用requests的时候，总是会输入多余INFO日志

[2014-11-17 20:04:38,664](DEBUG)root : 开始下载URL：http://www.baidu.com/

[2014-11-17 20:04:38,753](INFO)requests.packages.urllib3.connectionpool : Starting new HTTP connection (1): www.baidu.com

[2014-11-17 20:04:38,858](DEBUG)requests.packages.urllib3.connectionpool : "GET / HTTP/1.1" 200 16779

怎么关闭呢？

import logging 

logging.getLogger("requests").setLevel(logging.WARNING)

怎么打开详尽日志呢？

import requests 

import logging 

import httplib 

httplib.HTTPConnection.debuglevel = 1 

logging.basicConfig() 

logging.getLogger().setLevel(logging.DEBUG) 

requests_log = logging.getLogger("requests.packages.urllib3") 

requests_log.setLevel(logging.DEBUG) 

requests_log.propagate = True 

 requests.get('http://httpbin.org/headers')
