Get outgoing port number from urllib2

问题

I am using Python 2.6.x and urllib2 to do some web scraping, but I need really low-level socket information (really just the port number of the local socket) for each HTTP request. Does anyone know how to get that?

Thanks

EDIT:

Okay, I'm still trying to get this right, so I did what I thought should work but I'm not getting the output when I try and use the new stuff. What am I doing wrong here?

from urllib2 import *

class AbstractHTTPHandler(AbstractHTTPHandler):

    def do_open(self, http_class, req):
        """
          ...copy docstring...
        """
        print "woot!"
        ...copy code from urllib2.AbstractHTTPHandler.do_open...

回答1:

urllib2 can operate on different URL schemes, which may not even have a notion of socket. Instead, use http.client's undocumented sock property:

try:
    from http.client import HTTPConnection
except ImportError: # Python<3
    from httplib import HTTPConnection

h = HTTPConnection('example.net', 80)
h.request('GET', '/')
print('Local port: ' + str(h.sock.getsockname()[1]))
