How to Resolve Selenium Proxy Errors When Automating Web Actions Using Python?

Running Selenium Webdriver with a Proxy in Python: Troubleshooting Proxy Errors

Using Selenium Webdriver to automate web actions often requires the use of proxy servers. However, integrating a proxy into your Selenium script can present challenges.

One common issue is receiving an error message when the Selenium browser fails to access a specified URL or performs any action. Investigating the code may suggest an incorrect implementation of the proxy setup.

For instance, this code snippet demonstrates a basic Selenium Webdriver script that intends to navigate to Google Ireland and search for "selenium":

<code class="python">from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

myProxy = "http://149.215.113.110:70"

proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': myProxy,
    'ftpProxy': myProxy,
    'sslProxy': myProxy,
    'noProxy':''
})

driver = webdriver.Firefox(proxy=proxy)
driver.implicitly_wait(30)
driver.get("https://www.google.ie/#gs_rn=17&amp;gs_ri=psy-ab&amp;suggest=p&amp;cp=6&amp;gs_id=ix&amp;xhr=t&amp;q=selenium&amp;es_nrs=true&amp;pf=p&amp;output=search&amp;sclient=psy-ab&amp;oq=seleni&amp;gs_l=&amp;pbx=1&amp;bav=on.2,or.r_qf.&amp;bvm=bv.47883778,d.ZGU&amp;fp=7c0d9024de9ac6ab&amp;biw=592&amp;bih=665")</code>

However, executing this script may result in an error. To resolve this issue, a more concise and effective approach is recommended:

<code class="python">from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

prox = Proxy()
prox.proxy_type = ProxyType.MANUAL
prox.http_proxy = "ip_addr:port"
prox.socks_proxy = "ip_addr:port"
prox.ssl_proxy = "ip_addr:port"

capabilities = webdriver.DesiredCapabilities.CHROME
prox.add_to_capabilities(capabilities)

driver = webdriver.Chrome(desired_capabilities=capabilities)</code>

By utilizing this revised method, you should be able to successfully configure your Selenium Webdriver script with a proxy and perform the desired web automation tasks.
