python requests – Web crawling

To extract all YouTube links from a Facebook group and put them into a list, you can use a combination of web scraping and regular expressions (regex) in Python. Here’s a step-by-step guide on how to do this using the requests library for making HTTP requests and the re module for regex operations:

Install python & Bibliotheken:

apt install python3
python3 -V
# pip > Downloadtool
apt install pip
# Python requests Bibliothek > web-zugriffe
apt install python3-requests
# Python venv > Virtuell Enviroment für Python
apt install python3-venv
# Python Umgebung (zb pyEnv) erstellen
python3 -m venv pyEnv
# Python Umgebung (zb pyEnv) aktivieren
. pyEnv/bin/activate

Script um youtube links aus facebook zu extrahieren

  1. Access the Facebook Group Page: You need to access the Facebook group page where the links are located. This can be done using the requests library in Python.
  2. Extract HTML Content: Extract the HTML content of the Facebook group page.
  3. Extract YouTube Links: Use regex to find and extract YouTube links from the HTML content.
  4. Put Links in a List: Store the extracted YouTube links in a list.

Here’s a Python script to achieve this:

import requests
import re

def extract_youtube_links_from_facebook_group(group_url):
    # Step 1: Access the Facebook Group Page
    response = requests.get(group_url)
    if response.status_code != 200:
        print("Failed to retrieve the Facebook group page.")
        return []

    # Step 2: Extract HTML Content
    html_content = response.text

    # Step 3: Extract YouTube Links using regex
    youtube_links = re.findall(r'(https?://(?:www\.)?youtu(?:\.be|be\.com)/\S+)', html_content)

    # Step 4: Put Links in a List
    return youtube_links

# Example usage
group_url = 'YOUR_FACEBOOK_GROUP_URL_HERE'
youtube_links = extract_youtube_links_from_facebook_group(group_url)
print("YouTube Links:")
for link in youtube_links:
    print(link)

Replace 'YOUR_FACEBOOK_GROUP_URL_HERE' with the URL of the Facebook group you want to extract YouTube links from.

It’s worth noting that Facebook might change its HTML structure or employ anti-scraping measures, so this script might need adjustments if Facebook updates its layout or security measures. Additionally, make sure to abide by Facebook’s terms of service and the group’s rules regarding scraping data.
