Update  OP uses Python 3  So adding an example using httplib2  import httplib2  h   httplib2 Http   cache    h add credentials  name    password     Basic authentication  resp  content   h request  https   host path to resource    POST   body  foobar     The below works for python 2 6   I use pycurl a lot in production for a process which does upwards of 10 million requests per day   You ll need to import the following first   import pycurl import cStringIO import base64   Part of the basic authentication header consists of the username and password encoded as Base64    headers      Authorization     Basic  s    base64 b64encode  username password       In the HTTP header you will see this line Authorization  Basic dXNlcm5hbWU6cGFzc3dvcmQ   The encoded string changes depending on your username and password   We now need a place to write our HTTP response to and a curl connection handle   response   cStringIO StringIO   conn   pycurl Curl     We can set various curl options  For a complete list of options  see this  The linked documentation is for the libcurl API  but the options does not change for other language bindings   conn setopt pycurl VERBOSE  1  conn setopt pycurlHTTPHEADER     s   s    t for t in headers items      conn setopt pycurl URL   https   host path to resource   conn setopt pycurl POST  1    If you do not need to verify certificate  Warning  This is insecure  Similar to running curl -k or curl --insecure   conn setopt pycurl SSL VERIFYPEER  False  conn setopt pycurl SSL VERIFYHOST  False    Call cStringIO write for storing the HTTP response   conn setopt pycurl WRITEFUNCTION  response write    When you re making a POST request   post body    foobar  conn setopt pycurl POSTFIELDS  post body    Make the actual request now   conn perform     Do something based on the HTTP response code   http code   conn getinfo pycurl HTTP CODE  if http code is 200     print response getvalue

using only standard modules and no manual header encoding    which seems to be the intended and most portable way the concept of python urllib is to group the numerous attributes of the request into various managers directors contexts    which then process their parts  import urllib request  ssl    to avoid verifying ssl certificates httpsHa   urllib request HTTPSHandler context  ssl  create unverified context       setting up realm urls user-password auth    top level url may be sequence  also the complete url  realm None is default  top level url    https   ip port or domain    of the std managers  this can send user passwd in one go    not after HTTP req- gt 401 sequence password mgr   urllib request HTTPPasswordMgrWithPriorAuth   password mgr add password None  top level url   quot user quot    quot password quot   is authenticated True   handler   urllib request HTTPBasicAuthHandler password mgr    create OpenerDirector opener   urllib request build opener handler  httpsHa   url   top level url     some url some query     response   opener open url   print response read

In Python 3 the following will work   I am using the lower level http client from the standard library   Also check out section 2 of rfc2617 for details of basic authorization   This code won t check the certificate is valid  but will set up a https connection   See the http client docs on how to do that   from http client import HTTPSConnection from base64 import b64encode  This sets up the https connection c   HTTPSConnection  www google com    we need to base 64 encode it   and then decode it to acsii as python 3 stores it as a byte string userAndPass   b64encode b username password   decode  ascii   headers      Authorization     Basic  s     userAndPass    then connect c request  GET        headers headers   get the response back res   c getresponse     at this point you could check the status etc   this gets the page text data   res read

A correct way to do basic auth in Python3 urllib request with certificate validation follows   Note that certifi is not mandatory  You can use your OS bundle  likely  nix only  or distribute Mozilla s CA Bundle yourself  Or if the hosts you communicate with are just a few  concatenate CA file yourself from the hosts  CAs  which can reduce the risk of MitM attack caused by another corrupt CA      usr bin env python3   import urllib request import ssl  import certifi   context   ssl SSLContext ssl PROTOCOL TLSv1  context verify mode   ssl CERT REQUIRED context load verify locations certifi where    httpsHandler   urllib request HTTPSHandler context   context   manager   urllib request HTTPPasswordMgrWithDefaultRealm   manager add password None   https   domain com     username    password   authHandler   urllib request HTTPBasicAuthHandler manager   opener   urllib request build opener httpsHandler  authHandler     Used globally for all urllib request requests    If it doesn t fit your design  use opener directly  urllib request install opener opener   response   urllib request urlopen  https   domain com some path   print response read
