E-commerce review capture tool: e-commerce review capture

Why do I have to use a proxy IP to crawl e-commerce reviews?

To put it bluntly, now the e-commerce platform is like a thief staring at the crawler. If you use your own broadband to climb, not ten minutes guaranteed to give you IP blocking. last week a mother and baby products customers, write their own crawler script just ran for two days, the entire company's network has been an e-commerce platform black, even normal visits are affected.

It's time to rely on proxy IPs toReplacement of visiting identities on a rotating basisThe first thing you need to do is to go to the supermarket and research the price of goods. For example, if you want to go to the supermarket to research the price of goods, you can't wear the same clothes every day, right? Proxy IP is the key props of this dress-up game, making the platform feel that each visit is a different "customer" browsing the goods.

Hands-on with ipipgo to build a crawler shield

First of all, let's talk about a real case: an apparel e-commerce business ipipgo's residential agent, successfully crawled 200,000+ comment data on a daily basis. Their technical director said: "Since the use of dynamic IP pools, the collection success rate from 37% soared to 92%."

import requests
from itertools import cycle

 API provided by ipipgo to extract links (example)
proxy_api = "https://api.ipipgo.com/getproxy?type=resident&count=50"

 Get the pool of proxy IPs
proxy_list = requests.get(proxy_api).json()['data']
proxy_pool = cycle(proxy_list)

for page in range(1, 100): current_proxy = next(proxy_pool)
    current_proxy = next(proxy_pool)
    current_proxy = next(proxy_pool)
        response = requests.get(
            f "https://某电商.com/product/12345/comments?page={page}",
            proxies={"http": f "http://{current_proxy}"}, timeout=8, timeout=8, current_proxy = next(proxy_pool)
            timeout=8
        )
         Data parsing is handled here...
    except Exception as e.
        print(f "Failed with {current_proxy}, automatically switching to the next one.")

Here's the kicker: remember to setTimeout not to exceed 8 secondsThe response speed of ipipgo is generally within 1.2 seconds, and it is recommended that IPs exceeding 3 seconds be discarded directly.

Top 3 Tips for Avoiding the Acquisition Minefield

Don't think you can do whatever you want with a proxy IP, these details are still blocked if you don't pay attention to them:

Special note: remember to bring it with you when you climb the reviewReasonable Referer and User-AgentDon't use those outdated browser logos. ipipgo's Smart Routing feature automatically matches information about devices commonly used by local users, and this has been measured to reduce the probability of 30% interception.

Real-world QA: you've definitely encountered these problems

Q: Why do I still get blocked even if I use a proxy IP?
A: Ninety percent of the cases are using a low quality proxy. Many free agents in the market have been marked by the platform, and it is recommended to use ipipgo's high stash of residential agents, whose IP pool is updated daily at a rate of about 40%.

Q: How many IPs are needed to be sufficient?
A：According to our actual test, if you climb the domestic mainstream e-commerce, you need about 120 IP rotations per 500 requests/hour. ipipgo's package just has a specification of 150 IP/hour, and we suggest you to start from this level.

Q: What should I do if I encounter a CAPTCHA?
A: Don't just do it! When you find a CAPTCHA, suspend the task immediately and reduce the collection frequency after switching IPs. ipipgo's enterprise version comes with a CAPTCHA warning function, which can automatically adjust the strategy before triggering the CAPTCHA!

Why do you recommend ipipgo?

This is not a king's ransom. Last year during double 11, a customer doing price monitoring tested 5 service providers at the same time, and the result was ipipgo'sRequest success rate 89%It is 23 percentage points higher than the others on average. The key is that their home IP are real users real network environment, unlike some service providers to take the server room IP to fill the number.

I recently discovered a hidden feature: when using their API to get a proxy, add the&isp=multiparameters, you can mix the IPs of the three major carriers so that it looks more like natural traffic. Since using this trick, a certain customer has not been restricted for 3 months of continuous collection.

Lastly, a cold knowledge: many platforms will detect the IP survival time. ipipgo's residential proxy default 15 minutes to automatically replace the length of time will not be too short to waste resources, but also effectively avoid being marked, is the industry's golden balance point.
