Selenium Fetch HTML: Page Source Extraction

Hands-on teaching you to use Selenium to catch web pages when hanging proxies

Brothers engaged in data capture understand that the use of Selenium automation browser operation, often encountered IP is limited to the bad things. This is the time to call out the proxy IP this magic tool, especially like theipipgoThis kind of service provider that specializes in high-quality proxies can help you pull your crawl efficiency right up to full capacity.

Why do I have to use a proxy?

For example, if you continuously use the same IP to brush a certain website, you will be blocked in a minute. It's like going to the cafeteria and always jumping the queue, the aunty will definitely remember you. Hanging a proxy is like changing different clothes every day to go to the queue, the administrators simply do not recognize.

A crash course in Selenium basics

Install the necessary things first:

pip install selenium
 Remember to install the driver for your browser, e.g. chromedriver.

The base crawl code looks like this:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://目标网站")
print(driver.page_source) This is the source of the page you are looking for
driver.quit()

Putting a Proxy Vest on Selenium

Here comes the point! TakeipipgoAs an example, there are two ways to hang a proxy:

Method 1: Code Direct Configuration

from selenium.webdriver import Proxy
from selenium.webdriver.chrome import options

proxy_ip = "123.123.123.123:8888" This is the proxy provided by ipipgo.
proxy_auth = "username:password" The key obtained from the ipipgo backend.

options = webdriver.ChromeOptions()
options.add_argument(f'--proxy-server=http://{proxy_auth}@{proxy_ip}')
driver = webdriver.Chrome(options=options)

Method 2: Plug-in proxies (suitable for those requiring authentication)

 First go to the ipipgo backend and download the authentication plugin
chrome_options.add_extension('/path/to/ipipgo_auth.crx')

Guide to avoiding the pit

A common minefield for newbies:

1. Wrong proxy format → http://用户名:密码@ip:port
2. Forgot to deal with SSL certificate → add --ignore-certificate-errors parameter
3. IP pool is not enough → ipipgo's packages have a minimum of 5000+ IP pools

QA First Aid Station

Q: What should I do if I can't connect to the agent all the time?
A: Check the proxy format first, then use the one provided by ipipgoOnline testing toolsTest for IP survivability

Q: What should I do if I encounter website human verification?
A: Switch to ipipgo'sResidential AgentsThe simulation simulates real user behavior, and has been tested to effectively reduce the validation frequency.

Q: How do I manage proxies with multiple browsers open at the same time?
A: Use ipipgo'sAPI Dynamic IP AcquisitionIn addition, each browser instance is assigned a different proxy

Why ipipgo?

Having empirically compared seven or eight proxy services on the market, ipipgo has three killer features:

1. Exclusive IP live technology, single IP up to 3 hours of stability
2. millisecond response speed, faster than peers 40%+. 7x24 hours customer service.
3. 7x24 hours customer service, the last midnight problem solved in 5 minutes!

Especially for those who do e-commerce price monitoring, use their homeDynamic Residential IPWith Selenium, ran for half a month without triggering anti-climbing, saving enough time to eat three hot pot.

Lastly, new users who sign up for ipipgo should remember to get the2G Free Traffic PackI'm not sure if I'm going to be able to do that, but I'm going to have to run a small project to test the waters. Encounter technical problems directly to their engineers, more reliable than online search tutorials.
