I made a script to scrape data from a webpage which is cloudflare protected. I was scraping around 25k links from this website and the script was working fine. I have been able to extract all the links from this website and now want to scrape information from these links. Earlier the script was working well but because of recent security update in website, I am getting error 503 by requests library and "checking your browser" webpage by selenium. Is there any way to bypass it?
I also have scraper api subscription to make requests using proxies and using "scraper_api" library for the same.
I am sharing some of the links that needs to be scraped but getting these errors:
https://coinatmradar.com/bitcoin_atm/31285/bitcoin-atm-general-bytes-birmingham-altadena-spirits/
https://coinatmradar.com/bitcoin_atm/23676/bitcoin-atm-general-bytes-birmingham-marathon-gas/
Already tried other approaches like cfscraper, cloud scraper, undetected chromedriver, but no luck.
Please try to scrape any other link and share any solution. Thanks

I'm trying to scrape (Zone-H) to get some information, I found the website will execute JavaScript (called SlowAES).
But the website seems to detect that it is using Selenium ChromeDriver, because I can't download z.js, so I can't connect to the website.
I've added these two experimental options:
chrome_options.add_experimental_option('excludeSwitches',["enable-automation"])
chrome_options.add_experimental_option('useAutomationExtension',False)
But I still cannot get it to scrape.
I'm trying to access and get data from www.cclonline.com website using python script.
this is the code.
import requests
from requests_html import HTML
source = requests.get('https://www.cclonline.com/category/409/PC-Components/Graphics-Cards/')
html = HTML(html=source.text)
print(source.status_code)
print(html.text)
this is the errors i get,
403

What happened?
This website is using a security service to protect itself from online attacks.
how can i solve this problem? Thanks.
So the site's robots.txt does not explicitly says no bot is allowed. But you need to make your request look like it's coming from an actual browser.
Now to solve the issue at hand. The response says you need to have cookies enabled. So that can be solved by using a headless browser like selenium. Selenium has everything a browser has to offer (it basically uses google chrome or a browser of your chosen as a driver). It will make the server think the request is coming from an actual browser and will return a response.

Also remember to adjust crawl time accordingly. Make pauses after each request and swap user-agents often.
There’s no a silver bullet for solving cloudflare challenges, I’ve tried in my projects the solutions proposed here on this website, using playwright with different options https://substack.thewebscraping.club/p/cloudflare-how-to-scrape

Is the site not scrapable or do I need to use some other method?
I checked this answer: How to scrape aspx pages with python , but the solution is in selenium.
Is it possible to do it in python and Beautiful soup?
The reason is you are hitting a url which may be no longer served by the server. I am able to get data from all pages. I checked response from scrapy shell as
scrapy shell "http://judis.nic.in/supremecourt/chejudis.asp"
and using xpath you can retrieve whatever data you want from same page.
I'm not able to open the website though my browser. I'm getting the same response from my browser. Maybe that's why you're getting that response back.
I am writing a code in python using selenium and Beautiful Soup to scrape Upwork for job listings and descriptions. I now keep getting an error that says:
"Access to this web page is denied. Please make sure your browser
supports JavaScript and cookies and that you are not blocking them
from loading. To learn more about how Upwork uses cookies please
review our Cookie Policy."
Do they not want people to scrape their sites?
You may have to do
clear the cache and cookies
disable all the ad blockers
For more information, check Upwork
Upwork have official API and Python lib as well so they might not be that keen on you scraping the website.
You can find the documentation here.
https://developers.upwork.com/?lang=python#
There is a jobs endpoint that does what you want.

I want to use windmill or selenium to simulate a browser that visits a website, scrapes the content and after analyzing the content goes on with some action depending of the analysis.
As an example. The browser visits a website, where we can find, say 50 links. While the browser is still running, a python script for example can analyze the found links and decides on what link the browser should click.
My big question is with how many http Requests this can be done using windmill or selenium. I mean do these two programs can simulate visiting a website in a browser and scrape the content with just one http request, or would they use another internal request to the website for getting the links, while the browser is still running?
Thx alot!
Selenium uses the browser but number of HTTP request is not one. There will be multiple HTTP request to the server for JS, CSS and Images (if any) mentioned in the HTML document.
If you want to scrape the page with single HTTP request, you need to use scrapers which only gets what is present in the HTML source. If you are using Python, check out BeautifulSoup.
