Using Proxies With Python Selenium

Using Proxies With Python Selenium

Selenium is a powerful browser automation library that allows you to build bots and scrapers that can load and interact with web pages in the browser. As a result, Selenium is very popular amongst the Python web scraping community.

In this guide for The Python Selenium Web Scraping Playbook, we will look at how to integrate proxies into our Python Selenium based web scraper.

There are number of different types of proxies which you need to integrate differently with Selenium, so we will walk through how to integrate each type:

Using Proxies With Selenium​

The first and simplest type of proxy to integrate with Python Selenium are simple HTTP proxies (in the form of a IP address) that don't require authentication. For example:


"11.456.448.110:8080"

Depending on which type of browser you are using the integration method is slightly different.

Integrating Proxy With Selenium Chrome Browser​

To integrate this proxy IP into a Selenium scraper that uses a Chrome Browser we just need to set the --proxy-server arguement in our WebDriver options:


from selenium import webdriver

## Example Proxy
PROXY = "11.456.448.110:8080"

## Create WebDriver Options to Add Proxy
chrome_options = WebDriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server={PROXY}')
chrome = webdriver.Chrome(chrome_options=chrome_options)

## Make Request Using Proxy
chrome.get("https://httpbin.org/ip")

Now when we run the script we can see that Selenium is using the defined proxy IP:


{
    "origin": "11.456.448.110:8080"
}

Integrating Proxy With Selenium Firefox Browser​

To integrate this proxy IP into a Selenium scraper that uses a FireFox Browser we need to use the Proxy and ProxyType classes from the Selenium Webdriver library:


from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType
 
## Define Proxy
proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': "11.456.448.110:8080",
    'noProxy': ''
})

## Create Driver 
firefox_driver = webdriver.Firefox(proxy = proxy, executable_path=r"/root/geckodriver")
 
## Make Request Using Proxy
firefox_driver.get("https://httpbin.org/ip")

Now when we run the script we can see that Selenium is using the defined proxy IP:


{
    "origin": "11.456.448.110:8080"
}

HTTP Proxy Authentication

This method works fine when you don't need to add an authentication username and password to the proxy. We will look at how to use authenticated proxies in another section.

Using Authenticated Proxies With Selenium​

The above method doesn't work if you need to use proxies that require username and password authentication.

It is very common for commercial proxy providers to sell access to their proxy pools by giving you single proxy endpoint that you send your requests too and authenticate your account using a username and password.


"http://USERNAME:PASSWORD@proxy-server:8080"

There are a couple ways to solve this, but one of the easiest is to use the Selenium Wire extension which makes it very easy to use proxies with Selenium.

First, you need to install Selenium Wire using pip:


pip install selenium-wire

Then update your scraper to use the seleniumwire webdriver instead of the default selenium webdriver:


from seleniumwire import webdriver
from webdriver_manager.chrome import ChromeDriverManager

## Define Your Proxy Endpoints
proxy_options = {
    'proxy': {
        'http': 'http://USERNAME:PASSWORD@proxy-server:8080',
        'https': 'http://USERNAME:PASSWORD@proxy-server:8080',
        'no_proxy': 'localhost:127.0.0.1'
    }
}

## Set Up Selenium Chrome driver
driver = webdriver.Chrome(ChromeDriverManager().install(), 
                            seleniumwire_options=proxy_options)

## Send Request Using Proxy
driver.get('https://httpbin.org/ip')


Now when we run the script we can see that Selenium is using a proxy IP:


{
    "origin": "201.88.548.330:8080"
}

Integrating Proxy APIs​

Over the last few years there has been a huge surge in proxy providers that offer smart proxy solutions that handle all the proxy rotation, header selection, ban detection and retries on their end. These smart APIs typically provide their proxy services in a API endpoint format.

However, these proxy API endpoints don't integrate well with headless browsers when the website is using relative links as Selenium will try to attach the relative URL onto the proxy API endpoint not the websites root URL. Resulting, in some pages not loading correctly.

As a result, when integrating your Selenium scrapers it is recommended that you use their proxy port integration over the API endpoint integration when they provide them (not all do have a proxy port integration).

For example, in the case of the ScrapeOps Proxy Aggregator we offer a proxy port integration for situations like this.

The proxy port integration is a light front-end for the API and has all the same functionality and performance as sending requests to the API endpoint but allow you to integrate our proxy aggregator as you would with any normal proxy.

The following is an example of how to integrate the ScrapeOps Proxy Aggregator into your Selenium scraper using


from seleniumwire import webdriver
from webdriver_manager.chrome import ChromeDriverManager

SCRAPEOPS_API_KEY = 'APIKEY'

## Define ScrapeOps Proxy Port Endpoint
proxy_options = {
    'proxy': {
        'http': f'http://scrapeops:{SCRAPEOPS_API_KEY}@proxy.scrapeops.io:5353',
        'https': f'http://scrapeops:{SCRAPEOPS_API_KEY}@proxy.scrapeops.io:5353',
        'no_proxy': 'localhost:127.0.0.1'
    }
}

## Set Up Selenium Chrome driver
driver = webdriver.Chrome(ChromeDriverManager().install(), 
                            seleniumwire_options=proxy_options)

## Send Request Using ScrapeOps Proxy
driver.get('http://quotes.toscrape.com/')

tip

To use the ScrapeOps Proxy Aggregator, you first need an API key which you can get by signing up for a free account here which gives you 1,000 free API credits.
