Data Crawling Browser: Automation Tool with Proxy IP Integration

When Crawlers Meet CAPTCHA, Try This Life-Saving Trick

Engage in data collection of friends understand that the most afraid of the target site suddenly turn the other cheek. The hard-written crawler script, running on the run to receive 403 Forbidden, or jump out of the CAPTCHA chain set. If there is no preparation at this time, the progress of the project will have to be jammed.

Last year, a friend doing e-commerce planted in this, their team to catch the price of competitors to do market analysis. The first two days run quite smooth, the third day suddenly paralyzed the whole line, the IP directly be pulled black. Later used a dirt method, manually change the IP to continue to catch, the results of low efficiency, not to mention the staff overtime costs are over budget.

This Tool Will Make You Lose 80% Less Hair

There is now a kind on the marketDedicated browser for data collectionIn addition, the proxy IP function is directly integrated into the automation process. It's like putting a face-changing mask on the crawler, automatically switching identities every time you visit, and the site can't tell if it's a real person or a machine.

 Python example: automation script using ipipgo proxy
from selenium import webdriver

proxy = "http://user:pass@gateway.ipipgo.com:9020"
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server={proxy}')

driver = webdriver.Chrome(options=chrome_options)
driver.get("https://target-site.com")
 The follow-up is exactly the same as for a normal crawler...

focus onProxy IP quality, here it is recommended to use ipipgo's exclusive IP pool. They have a cold but useful feature in their house - theBusiness Scenario Customization, for example, IP segments specialized for e-commerce platforms have a much higher success rate than generic proxies.

Anti-Blocking Setup in Three Steps

1. Create a project in the ipipgo backend and selectDedicated channel for data acquisition
2. Set up IP switching rules (it is recommended to change 1 time for every 50 pages captured)
3. Binding API keys for automation tools

There's a point that's easy to miss.request header masquerading asThe UA library in the backend of ipipgo can be called directly, so don't be silly and collect it yourself.

A QA session that even a white person can understand

Q: Will using a proxy slow down the collection speed?
A: It depends on the quality of the agent's line. Like ipipgo's BGP hybrid line, the measured delay can be controlled within 200ms, which is more than 10 times faster than some free agents.

Q: What should I do if I encounter a CAPTCHA?
A: It is recommended that a two-pronged approach: ① set the frequency of visits does not exceed 3 times / sec ② with the coding platform (here note that do not use the same service provider, easy to expose the characteristics)

Q: How can I tell if a proxy is in effect?
A: There is a real-time monitoring dashboard in the backend of ipipgo, you can see the usage status of each IP. There is a tricky way, first visit httpbin.org/ip to see if the returned IP is correct.

I've stepped in these potholes for you.

- Don't buy a shared IP for cheap, the probability of being blocked is extremely high!
- Higher success rate of collection from 2-5am (website risk control strategies will be relaxed)
- Don't fight the slider validation, it's often easier to retry with a different IP.
- Important items recommended for purchaseCity-level IP librariesI think it's better to use something like ipipgo that can pinpoint counties.

Finally, a real case: after a used car platform used this method, the data collection efficiency was increased from 30,000 to 500,000 items per day, and it ran continuously for three months without being blocked. The key point is that they used ipipgo'sHybrid model of residential agent + server room agent, modeling the request characteristics almost identically to real users.
