Diagnosing proxy issue with python -


so trying work python 2.7 various things require pulling data internet. have not been successful, , looking diagnose doing wrong.

firstly managed pip work by defining proxy so, pip install --proxy=http://username:password@someproxy.com:8080 numpy. hence python must capable of getting through it!

however when came writing .py script same have had no success. tried using following code urllib2 first:

import urllib2  uri = "http://www.python.org" http_proxy_server = "someproxyserver.com" http_proxy_port = "8080" http_proxy_realm = http_proxy_server http_proxy_user = "username" http_proxy_passwd = "password"  # next line = "http://username:password@someproxyserver.com:8080" http_proxy_full_auth_string = "http://%s:%s@%s:%s" % (http_proxy_user,                                                       http_proxy_passwd,                                                       http_proxy_server,                                                       http_proxy_port)  def open_url_no_proxy():     urllib2.urlopen(uri)      print "apparent success without proxy server!"      def open_url_installed_opener():     proxy_handler = urllib2.proxyhandler({"http": http_proxy_full_auth_string})      opener = urllib2.build_opener(proxy_handler)     urllib2.install_opener(opener)     urllib2.urlopen(uri)      print "apparent success through proxy server!"  if __name__ == "__main__":     open_url_no_proxy()     open_url_installed_opener() 

however error:

urlerror: <urlopen error [errno 10060] connection attempt failed because connected party did not respond after period of time, or established connection failed because connected host has failed respond> 

then tried urllib3 module used pip handle proxies:

from urllib3 import proxymanager, make_headers  # establish authentication settings default_headers = make_headers(basic_auth='username:password') http = proxymanager("https://www.proxy.com:8080/", headers=default_headers)  # can use `http` normal poolmanager r = http.request('get', 'https://www.python.org/')  # check data destination print(r.data) 

i got error:

raise maxretryerror(_pool, url, error or responseerror(cause)) maxretryerror: httpsconnectionpool(host='www.python.org', port=443): max retries exceeded url: / (caused proxyerror('cannot connect proxy.', error('tunnel connection failed: 407 proxy authorization required',))) 

i appreciate diagnosing issue.

the solution problem use requests module, see below thread: proxies python 'requests' module

mtt2p list code worked me.

import requests import time class basecheck():     def __init__(self, url):         self.http_proxy  = "http://user:pw@proxy:8080"         self.https_proxy = "http://user:pw@proxy:8080"         self.ftp_proxy   = "http://user:pw@proxy:8080"         self.proxydict = {                       "http"  : self.http_proxy,                       "https" : self.https_proxy,                       "ftp"   : self.ftp_proxy                     }         self.url = url         def makearr(tsteps):             global stemps             global steps             stemps = {}             step in tsteps:                 stemps[step] = { 'start': 0, 'end': 0 }             steps = tsteps         makearr(['init','check'])         def starttime(typ = ""):             stemp in stemps:                 if typ == "":                     stemps[stemp]['start'] = time.time()                 else:                     stemps[stemp][typ] = time.time()         starttime()     def __str__(self):         return str(self.url)     def getrequests(self):         g=requests.get(self.url,proxies=self.proxydict)         print g.status_code         print g.content         print self.url         stemps['init']['end'] = time.time()         #print stemps['init']['end'] - stemps['init']['start']         x= stemps['init']['end'] - stemps['init']['start']         print x   test=basecheck(url='http://google.com') test.getrequests()
