DebugLog

　　可以用來查看收發包的情況，比較有意思，現特意記錄下來：

Sample:

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')

運行結果：

send: 'GET http://www.baidu.com 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 \r\n' header: Content-Length: 111470 header: Bdqid: 0xac52fd1000001301 header: X-Powered-By: HPHP header: Set-Cookie: BAIDUID=C79A798AE88AE217892800990B29F9AF:FG=1; expires=Thu, 31-Dec-37 23:55:55 GMT; max-age=2147483647; path=/; domain=.baidu.com header: Set-Cookie: BIDUPSID=C79A798AE88AE217892800990B29F9AF; expires=Thu, 31-Dec-37 23:55:55 GMT; max-age=2147483647; path=/; domain=.baidu.com header: Set-Cookie: PSTM=1506586983; expires=Thu, 31-Dec-37 23:55:55 GMT; max-age=2147483647; path=/; domain=.baidu.com header: Set-Cookie: BDSVRTM=0; path=/ header: Set-Cookie: BD_HOME=0; path=/ header: Set-Cookie: H_PS_PSSID=1442_21084_17001_22072; path=/; domain=.baidu.com header: Expires: Thu, 28 Sep 2017 08:22:20 GMT header: Bduserid: 0 header: Server: BWS/1.1 header: Cxy_All: baidu+93815e78c13d58fab2103ab02b94c0d4 header: Date: Thu, 28 Sep 2017 08:23:03 GMT header: P3P: CP=" OTI DSP COR IVA OUR IND COM " header: Content-Type: text/html; charset=utf-8 header: Bdpagetype: 1 header: X-Ua-Compatible: IE=Edge,chrome=1
