Facebook Post Crawler: FB Content Crawling Techniques

Hands-on with Proxy IP to Catch Facebook Posts

Those who are engaged in data collection know that Facebook's protection mechanism is stricter than the neighborhood gate. Last week, a cross-border e-commerce old brother to find me trolling, just captured 200 posts on the account was blocked. Today, I will give you a trick to use proxy IP to crack this problem.

Don't be sloppy with your tools.

Let's start with the must-have guy stuff:

1. Python environment(version 3.8+ recommended)
2. Requests library(Required for sending requests)
3. Reliable proxy IP services(Here we recommend ipipgo's Dynamic Residential Proxy)

import requests
from random import choice

 Sample proxies pool provided by ipipgo
proxies_pool = [
    "103.88.46.22:8000",
    "45.159.93.77:8080",
    "198.199.123.1:3128"
]

def get_fb_post(post_id).
    proxy = {"http": f "http://{choice(proxies_pool)}"}
    try.
        response = requests.get(
            f "https://facebook.com/posts/{post_id}",
            proxies=proxy,
            timeout=10
        )
        return response.text
    except Exception as e.
        print("Crawl error:", e)

Proxy IP Configuration Three Key Points

Anti-Blocking Strategies to Remember

A real case in point: there's a team that does competitive product analysis with ipipgo'sAutomatic rotation of agentsThe function, collected for 3 days in a row without triggering the ban. The key operation is just two points:

1. Request header camouflage: Randomly generate User-Agent for each request
2. Request intervals: Setting a random delay of 3-8 seconds

Frequently Asked Questions QA

Q: Why is it still blocked after using a proxy?
A: Check three points: ① IP purity is enough ② request frequency is too high ③ there is no simulation of real human operation. Suggest trying ipipgoHigh Stash Agents, their home IP survival rate can go up to 95% or more.

Q: What should I do if the collection speed is too slow?
A: Try ipipgo'sExclusive agent pool, supports multi-threaded concurrent acquisition. Remember to set a reasonable timeout (8-15 seconds is recommended).

Q: How do I break the CAPTCHA when I encounter it?
A: This situation requires: ① immediately switch to a new IP ② clean up the browser fingerprints ③ reduce the collection frequency. ipipgo's proxy pool has a 5-second fast switching function, which can effectively bypass the CAPTCHA.

Here's a guide to avoiding the pitfalls

Last year, I helped a customer debugging collection script, found that he made a typical mistake - all requests go to the same export IP. later changed to ipipipgoIntelligent Routingfunction, automatically assign IPs in different geographic regions, and the collection success rate directly soars from 40% to 89%.

As a final reminder, selecting a proxy service provider depends on theIP Survival Timerespond in singingConnection Success RateThe following are some of the reasons why you should use a free proxy. Like ipipgo this kind of professional service provider, there will be a specialized technical team to maintain the quality of the IP pool, more stable than with a free proxy.
