python访问的时候，将debug信息打印出来

import urllib2
httpHandler = urllib2.HTTPHandler(debuglevel=1)
httpsHandler = urllib2.HTTPSHandler(debuglevel=1)
opener = urllib2.build_opener(httpHandler, httpsHandler)
urllib2.install_opener(opener)
response = urllib2.urlopen('http://www.baidu.com')
print 'a'
print response.read()

免得抓包 在打印台都打印出来 请求，相应信息打印出来

send: 'GET / HTTP/1.1\r\nAccept-Encoding: identity\r\nHost: www.baidu.com\r\nConnection: close\r\nUser-Agent: Python-urllib/2.7\r\n\r\n'

reply: 'HTTP/1.1 200 OK\r\n'
