Python Requests Forbidden 403 Web Scraping

If you are trying to scrape a website using Python Requests library and you encounter a "Forbidden 403" error, it means that you are being denied access to the website by the server. This is often due to the website's security measures, which are put in place to prevent unauthorized access and data scraping.

Reasons for 403 Forbidden Error

  • Website's security measures
  • Website's anti-scraping measures
  • IP address or User Agent is blacklisted

Solutions for 403 Forbidden Error

If you encounter a 403 Forbidden error while web scraping, there are several solutions you can try:

1. Change User Agent

The first thing you can try is to change the user agent of your requests. Many websites block scraping bots and spiders by identifying their user agents. By changing your user agent, you can make your scraper appear as a regular browser.


import requests

url = 'https://www.example.com'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

response = requests.get(url, headers=headers)

2. Use Proxy Servers

If changing the user agent doesn't work, you can try using a proxy server. A proxy server will act as an intermediary between your scraper and the website, making it difficult for the website to identify your scraper's IP address.


import requests

url = 'https://www.example.com'
proxies = {'http': 'http://:', 'https': 'https://:'}

response = requests.get(url, proxies=proxies)

3. Add Delay

Another solution is to add a delay between your requests. This will give the impression that your scraper is a human user, and not a bot. You can use the time module in Python to add a delay.


import requests
import time

url = 'https://www.example.com'

for i in range(10):
    response = requests.get(url)
    time.sleep(1)

4. Contact Website Owner

If none of the above solutions work, you can try contacting the website owner and asking for permission to scrape their website. Some websites allow scraping for certain purposes, as long as the scraper is not causing any harm or violating any laws.

Conclusion

Scraping websites can be challenging due to various security measures put in place by website owners. However, by using the solutions mentioned above, you can bypass the 403 Forbidden error and successfully scrape the website.
