What's the best way to specify a proxy with username and password for an http connection in python?

Use this:
import requests
proxies = {"http":"http://username:password@proxy_ip:proxy_port"}
r = requests.get("http://www.example.com/", proxies=proxies)
print(r.content)
I think it's much simpler than using urllib
. I don't understand why people love using urllib
so much.

Here is the method use urllib
import urllib.request
# set up authentication info
authinfo = urllib.request.HTTPBasicAuthHandler()
proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"})
# build a new opener that adds authentication and caching FTP handlers
opener = urllib.request.build_opener(proxy_support, authinfo,
urllib.request.CacheFTPHandler)
# install it
urllib.request.install_opener(opener)
f = urllib.request.urlopen('http://www.python.org/')

Or if you want to install it, so that it is always used with urllib2.urlopen (so you don't need to keep a reference to the opener around):
import urllib2
url = 'www.proxyurl.com'
username = 'user'
password = 'pass'
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
# None, with the "WithDefaultRealm" password manager means
# that the user/pass will be used for any realm (where
# there isn't a more specific match).
password_mgr.add_password(None, url, username, password)
auth_handler = urllib2.HTTPBasicAuthHandler(password_mgr)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)
print urllib2.urlopen("http://www.example.com/folder/page.html").read()

This works for me:
import urllib2
proxy = urllib2.ProxyHandler({'http': 'http://
username:password@proxyurl:proxyport'})
auth = urllib2.HTTPBasicAuthHandler()
opener = urllib2.build_opener(proxy, auth, urllib2.HTTPHandler)
urllib2.install_opener(opener)
conn = urllib2.urlopen('http://python.org')
return_str = conn.read()

Setting an environment var named http_proxy like this: http://username:password@proxy_url:port

The best way of going through a proxy that requires authentication is using urllib2 to build a custom url opener, then using that to make all the requests you want to go through the proxy. Note in particular, you probably don't want to embed the proxy password in the url or the python source code (unless it's just a quick hack).
import urllib2
def get_proxy_opener(proxyurl, proxyuser, proxypass, proxyscheme="http"):
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_mgr.add_password(None, proxyurl, proxyuser, proxypass)
proxy_handler = urllib2.ProxyHandler({proxyscheme: proxyurl})
proxy_auth_handler = urllib2.ProxyBasicAuthHandler(password_mgr)
return urllib2.build_opener(proxy_handler, proxy_auth_handler)
if __name__ == "__main__":
import sys
if len(sys.argv) > 4:
url_opener = get_proxy_opener(*sys.argv[1:4])
for url in sys.argv[4:]:
print url_opener.open(url).headers
else:
print "Usage:", sys.argv[0], "proxy user pass fetchurls..."
In a more complex program, you can seperate these components out as appropriate (for instance, only using one password manager for the lifetime of the application). The python documentation has more examples on how to do complex things with urllib2 that you might also find useful.
