multithreading - Python proxy checker, change to threaded version -

-

I have checked some dragon proxy.

And to accelerate the investigation, I decided the change version for multi-sequence,

and thread module is the first for me, I was tried several times the version < / P>

Thread and many information is to convert to look, but it is not so easy for newbie python programmers.

If someone can really appreciate me very much !!

Thanks in advance!

urlib2, socket socket.setdefaulttimeout (180) # proxyList proxyList = Read the list of Proxy IPs in open ('listproxy.txt') .read () Def is_bad_proxy (Pip): Try : Proxy_handler = urllib2.ProxyHandler: opener = urllib2.build_opener (proxy_handler) opener.addheaders = [('user-agent' ({'http' pip} ',' Mozilla / 5.0 ')] Urllib2.install_opener (openers) Req = urllib2.Request ('http://www.yahoo.com') # & lt; --- Check whether the proxy is alive except sock = urllib2.urlopen (req) urllib2.HTTPError, e: print 'error code:', except exception, expansion e.code return e.code: print "error:" , Expansion return 1 return for items in proxyList: if_bad_proxy (item): print "bad proxy", item other: print item, "working"

urllib2.install_opener () installs the function global opener, i.e. this thread is not secure I am its Do not call the opener.open () method instead of global urllib2.urlopen () function abuse. Also use the class from the queue queue module to hold the list of proxies to check. It's OK to use the rest of your code in threaded mode.

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
