Selenium Crawler|Automated Browser Actions Solution

When Crawler Meets Anti-Crawler | Can't Escape IP Blocking Even Manually Operating Your Browser?

If you use Selenium to do data collection friends understand, obviously simulate the real operation of the browser, the result is still blocked by the website IP. last week there is an e-commerce price comparison of buddies, open 10 browser instances to catch the price data, less than two hours the IP will be pulled black. This thing is like a gopher - just change the new IP, and then have to change.

Here's a misconception to correct:Browser automation ≠ real person access. Web site wind control system will focus on these characteristics: a large number of requests in a short period of time, the same User-Agent high frequency, IP address fixed. Even if you use a random click interval, as long as the IP is not changed, it will still be exposed.

Proxy IP Tips for Your Browser

Take Python+Selenium as an example, the core of the two steps: to the browser instance hanging proxy + dynamic switching identity. We recommend using ipipgo's short-lived proxy, each time you start the browser to change the new IP, the test can carry the e-commerce platform for 8 hours to collect.

from selenium import webdriver

proxy = "123.123.123.123:8888" proxy address extracted by ipipgo
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server=http://{proxy}')

driver = webdriver.Chrome(options=chrome_options)
driver.get("https://目标网站.com") 

Watch out for the three pits:①Don't use free agents(slow and exposed)② HTTP/HTTPS protocols to be matched ③Remember to clean your browser fingerprintsThe first thing I'd like to do is to get a good deal on the HTTP proxy package. Recommended ipipgo socks5 proxy package, support for automatic protocol switching, measured than ordinary HTTP proxy survival time 3 times longer.

Anti-blocking Guide | This is the best way to set up the parameters.

Recommended for ipipgoDynamic Residential Agents, comes with an automatic IP rotation function. With their API, you can set the auto-replacement threshold in the code so that the program will automatically switch before triggering the wind control, which is much more hassle-free than managing it manually.

Frequently Asked Questions First Aid Kit

Q: Why is it still blocked even though it's obviously hooked up to a proxy?
A: Check if you missed the browser fingerprinting protection. Suggest adding these two sentences to the code:

chrome_options.add_argument("--disable-blink-features=AutomationControlled")
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])

Q: What should I do if the proxy IP connection times out?
A: Go with ipipgo'sHigh-speed server room linesIf you are doing cross-border collection, remember to choose the local ISP agent of the target country, for example, if you are catching American websites, you can use the IP segments of Comcast and AT&T.

Q: What if I need to process a CAPTCHA?
A: ipipgo'sLong-lasting static residential IPUsed in conjunction with a coding platform. The access behavior of such IPs is more like that of real users, and the probability of triggering a CAPTCHA can be reduced by about 60%.

Why do you recommend ipipgo?

Having tested 7 proxy providers, ipipgo wins solidly on three key metrics:
1. IP purity:: 95%+ IPs not tagged by mainstream sites
2. Connection Success Rate: API mode to 99.2%
3. quality-price ratio: 3 times more IP inventory for the same price

Especially theirIntelligent Routing TechnologyThe system can automatically allocate the optimal line. Last time to help customers deploy crawler system, with ipipgo after the data collection efficiency directly doubled, maintenance costs cut in half. Now their official website registration also send 10G flow package, enough to test the small project with.
