[python] Proxies with Python 'Requests' module

Just a short, simple one about the excellent Requests module for Python.

I can't seem to find in the documentation what the variable 'proxies' should contain. When I send it a dict with a standard "IP:PORT" value it rejected it asking for 2 values. So, I guess (because this doesn't seem to be covered in the docs) that the first value is the ip and the second the port?

The docs mention this only:

proxies – (optional) Dictionary mapping protocol to the URL of the proxy.

So I tried this... what should I be doing?

proxy = { ip: port}

and should I convert these to some type before putting them in the dict?

r = requests.get(url,headers=headers,proxies=proxy)

You can refer to the proxy documentation here.

If you need to use a proxy, you can configure individual requests with the proxies argument to any request method:

import requests

proxies = {
  "http": "http://10.10.1.10:3128",
  "https": "https://10.10.1.10:1080",
}

requests.get("http://example.org", proxies=proxies)

To use HTTP Basic Auth with your proxy, use the http://user:[email protected]/ syntax:

proxies = {
    "http": "http://user:[email protected]:3128/"
}

If you'd like to persisist cookies and session data, you'd best do it like this:

import requests

proxies = {
    'http': 'http://user:[email protected]:3128',
    'https': 'https://user:[email protected]:3128',
}

# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies

# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')

I have found that urllib has some really good code to pick up the system's proxy settings and they happen to be in the correct form to use directly. You can use this like:

import urllib

...
r = requests.get('http://example.org', proxies=urllib.request.getproxies())

It works really well and urllib knows about getting Mac OS X and Windows settings as well.

The accepted answer was a good start for me, but I kept getting the following error:

AssertionError: Not supported proxy scheme None

Fix to this was to specify the http:// in the proxy url thus:

http_proxy  = "http://194.62.145.248:8080"
https_proxy  = "https://194.62.145.248:8080"
ftp_proxy   = "10.10.1.10:3128"

proxyDict = {
              "http"  : http_proxy,
              "https" : https_proxy,
              "ftp"   : ftp_proxy
            }

I'd be interested as to why the original works for some people but not me.

Edit: I see the main answer is now updated to reflect this :)

It’s a bit late but here is a wrapper class that simplifies scraping proxies and then making an http POST or GET:

ProxyRequests

8 years late. But I like:

import os
import requests

os.environ['HTTP_PROXY'] = os.environ['http_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['HTTPS_PROXY'] = os.environ['https_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['NO_PROXY'] = os.environ['no_proxy'] = '127.0.0.1,localhost,.local'

r = requests.get('https://example.com')  # , verify=False

i just made a proxy graber and also can connect with same grabed proxy without any input here is :

#Import Modules

from termcolor import colored
from selenium import webdriver
import requests
import os
import sys
import time

#Proxy Grab

options = webdriver.ChromeOptions()
options.add_argument('headless')
driver = webdriver.Chrome(chrome_options=options)
driver.get("https://www.sslproxies.org/")
tbody = driver.find_element_by_tag_name("tbody")
cell = tbody.find_elements_by_tag_name("tr")
for column in cell:

        column = column.text.split(" ")
        print(colored(column[0]+":"+column[1],'yellow'))
driver.quit()
print("")

os.system('clear')
os.system('cls')

#Proxy Connection

print(colored('Getting Proxies from graber...','green'))
time.sleep(2)
os.system('clear')
os.system('cls')
proxy = {"http": "http://"+ column[0]+":"+column[1]}
url = 'https://mobile.facebook.com/login'
r = requests.get(url,  proxies=proxy)
print("")
print(colored('Connecting using proxy' ,'green'))
print("")
sts = r.status_code

I share some code how to fetch proxies from the site "https://free-proxy-list.net" and store data to a file compatible with tools like "Elite Proxy Switcher"(format IP:PORT):

##PROXY_UPDATER - get free proxies from https://free-proxy-list.net/

from lxml.html import fromstring
import requests
from itertools import cycle
import traceback
import re

######################FIND PROXIES#########################################
def get_proxies():
    url = 'https://free-proxy-list.net/'
    response = requests.get(url)
    parser = fromstring(response.text)
    proxies = set()
    for i in parser.xpath('//tbody/tr')[:299]:   #299 proxies max
        proxy = ":".join([i.xpath('.//td[1]/text()') 
        [0],i.xpath('.//td[2]/text()')[0]])
        proxies.add(proxy)
    return proxies



######################write to file in format   IP:PORT######################
try:
    proxies = get_proxies()
    f=open('proxy_list.txt','w')
    for proxy in proxies:
        f.write(proxy+'\n')
    f.close()
    print ("DONE")
except:
    print ("MAJOR ERROR")

here is my basic class in python for the requests module with some proxy configs and stopwatch !

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 = {}
            for step in tsteps:
                stemps[step] = { 'start': 0, 'end': 0 }
            steps = tsteps
        makearr(['init','check'])
        def starttime(typ = ""):
            for 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
