Facebook Mall Collector: Product Data Capture Solution

This may be the most realistic Facebook harvesting cheat sheet you've ever seen!

Engaged in the Facebook mall data crawl know that the biggest headache is not how to write the code, but how to make the account live through three days. Those who teach you to use requests library to climb data tutorials, nine out of ten did not tell you the key points:IP address is more important than account password. Today, we're going to harp on some truths that no one else dares to tell, especially how to keep your capture account with ipipgo's proxy service.

Why is your collector always blocked?

Imagine you're at the mall taking pictures of people as you see them, who is the security guard going to stare at if not you?That's what Facebook's monitoring system is all about. They look at three main things:

1. The same IP access frequency (more than 50 times / hour will be blocked)
2. IP belongs to anomalies (the United States in the morning and Brazil in the afternoon)
3. request characteristics are identical (all requests come from the same server room)

Last month there was a wholesale clothing customer, using their own server to grab data, the results of the next day even the main account was blocked. Later changed to ipipgo's dynamic residential IP pool, continuous running for half a month are fine.

Choosing a proxy IP is like choosing running shoes

Comparison of common agent types on the market (focus on the third column):

Focusing on Dynamic Residential IPs, there is a wonderful use for this product from ipipgo:Automatic city switching per request. For example, if you set the US region, the first request will be Los Angeles IP, and the second will become Chicago, which perfectly simulates the real user behavior.

Hands-on configuration of the collector

In the case of Python, for example, there are three places to change in the key configuration:

import requests

 Get the proxy address from ipipgo (remember to replace it with your own API)
proxy = "http://用户名:密码@gateway.ipipgo.com:端口"

 Focus on setting the timeout parameter
response = requests.get(
    'https://www.facebook.com/marketplace',
    proxies={'http': proxy, 'https': proxy},
    timeout=(3, 7) 3 seconds to connect, 7 seconds to read
)

 Random sleep mimics manual operation
import random
time.sleep(random.uniform(1.2, 4.5))

Attention! Many people planted on the timeout settings, when the site loads slowly, the default timeout settings will lead to TCP connection anomalies, directly exposing the proxy characteristics.

Five Details of Anti-Blocking

1. Don't use the Chrome driver.: Selenium is easy to detect, switch to Requests + random request header
2. Control the speed of the click: page dwell time to have random fluctuations of 0.5-3 seconds
3. Stagger active hours: U.S. users don't go crazy swiping items at 3 a.m.
4. Mouse track simulation: Use PyMouse to do random movements, don't click in a straight line!
5. Regular Cache Cleaning: tracking data especially in LocalStorage

Frequently Asked Questions QA

Q: Why is it still blocked after using a proxy?
A: Check the size of the IP pool, it is recommended that more than 500+ dynamic IPs are rotated. ipipgo's business version supports 1500 cities to switch automatically!

Q: What if the data collected is incomplete?
A: Most likely it is triggering the load limit, try adding "sec-fetch-site: same-origin" in the request header.

Q: Do I need to work with the fingerprint browser?
A: Long-term operational needs, short-term collection with random User-Agent is sufficient. ipipgo provides device fingerprint obfuscation service.

Tell the truth.

I've seen too many people spend a lot of money to buy collection software, the results in the IP link to fall. Last week there was a customer, had to use a free proxy, the results of the account was lost. In fact, the professional things to professional tools, ipipgoDynamic IP + automatic retry mechanismIt's a great way to save more money than if you were to toss it yourself. New users receive a 3-day trial, enough to measure the effect.
