python - Proxy with urllib2

Question

I open urls with:

site = urllib2.urlopen('http://google.com')

And what I want to do is connect the same way with a proxy I got somewhere telling me:

site = urllib2.urlopen('http://google.com', proxies={'http':'127.0.0.1'})

but that didn't work either.

I know urllib2 has something like a proxy handler, but I can't recall that function.

Answer 1

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
