Using urllib2 with SOCKS proxy
Solution 1:
Try with pycurl:
import pycurl
c1 = pycurl.Curl()
c1.setopt(pycurl.URL, 'http://www.google.com')
c1.setopt(pycurl.PROXY, 'localhost')
c1.setopt(pycurl.PROXYPORT, 8080)
c1.setopt(pycurl.PROXYTYPE, pycurl.PROXYTYPE_SOCKS5)
c2 = pycurl.Curl()
c2.setopt(pycurl.URL, 'http://www.yahoo.com')
c2.setopt(pycurl.PROXY, 'localhost')
c2.setopt(pycurl.PROXYPORT, 8081)
c2.setopt(pycurl.PROXYTYPE, pycurl.PROXYTYPE_SOCKS5)
c1.perform()
c2.perform()
Solution 2:
Yes, you can. I repeat my answer on How can I use a SOCKS 4/5 proxy with urllib2? You need to create an opener for every proxy like you do with an http proxy. The code for adding this feature to SocksiPy is available in GitHub https://gist.github.com/869791 and is as simple as:
opener = urllib2.build_opener(SocksiPyHandler(socks.PROXY_TYPE_SOCKS4, 'localhost', 9999))
print opener.open('http://www.whatismyip.com/automation/n09230945.asp').read()
For more information I've written an example running multiple Tor instances to behave like a rotating proxy: Distributed Scraping With Multiple Tor Circuits
