kandi X-RAY | cloudscraper Summary
Node.js library to bypass Cloudflare’s anti-ddos page. [Greenkeeper badge] If the page you want to access is protected by Cloudflare, it will return special page, which expects client to support Javascript to solve challenge. This small library encapsulates logic which extracts challenge, solves it, submits and returns the request page body. You can use cloudscraper even if you are not sure if Cloudflare protection is turned on. In general, Cloudflare has 4 types of common anti-bot pages: - Simple html+javascript page with challenge - Page which redirects to original site - Page with reCAPTCHA - Page with error ( your ip was banned, etc). If you notice that for some reason cloudscraper stops working, do not hesitate and get in touch with me ( by creating an issue [here] for example), so i can update it. Cloudscraper uses request-promise by default since v3. You can find the migration guide [here.] docs/migration-guide.md).

QUESTION
I'm trying to collect information from a cloudflare-protected website I believe. I've tried three alternatives and they all return empty values. So, I don't know if the site has any blockages or if I'm doing something wrong.
--Update
The solution proposed by F.Hoque works, however, when I try to use it in Colab, I only get an empty value.
Using request

Answered 2022-Mar-30 at 16:45Yes,the website is using cloudflare protection.

Here want the 6th table in the webpage. There are multiple tables on the webpage numbered 0 to 15 need to assign the table number to a variable.
...ANSWER
Answered 2022-Mar-21 at 16:15I'm not sure why you are getting the error of z being a set. You might want to add a print statement of print(z) right before to clearly see what's happening. Otherwise, there are some other problems with the code.

QUESTION
I am using the cloudscraper python library, installed from the Pycharm UI. Therefore, I am using the main version of this package.
I would like to try to use the dev version of this package, that can be downloaded through github from the relative branch (https://github.com/VeNoMouS/cloudscraper/tree/dev). In order to install this dev package, I have to run python setup.py install.
Is there a way to keep both versions of this module? How can I install the dev package directly from the UI?
ANSWER
Answered 2022-Jan-17 at 10:36Python does not handle having multiple versions of the same library installed. See for example this related question.
Indeed, the solution is to modify the files for one of the version to give it a different name (for example cloudscraper-dev).
Or you could have two different virtual env, one for each version, but it requires to switch from one to the other.
QUESTION
In a previous question I got the answer from Hedgehog! (How to check for new discounts and send to telegram if changes detected?)
But another question is, how can I get only the new (products) items in the output and not all the text what is changed. My feeling is that the output I got is literally anything what is changed on the website and not only the new added discount.
Here is the code, and see the attachment what the output is. Thanks again for all the effort.
...ANSWER
Answered 2021-Dec-13 at 10:14As discussed, your assumptions are going in the right direction, all the changes identified by the difflib will be displayed.
It may be possible to adjust the content of difflib but I am sure that difflib is not absolutely necessary for this task.
First step is to upgrade get_discounts(soup) to not only check if discount is in range but also get information of the item itself, if you like to display or operate on later:
QUESTION
I like to scrape new discounts from website and text me on telegram with a change on the website.
This is working but i got to much messages and i want to change the script to check a specific class on the website.
So on the website i want to check the -49%
I want a message if the value is between -65% and -99%. Is this possible? The script to check changes is below here:
...ANSWER
Answered 2021-Dec-11 at 14:01A simple possible solution to get a clue if there are any discounts between -65% and -99% could be the following.
This function is taking your soup and is looking for the discounts in generally and returns True if there is any discount in your range or False if not:
QUESTION
I am using PySimpleGui. I want to have a local place holder image.jpg until the button is pressed to load in a URL based JPG.
From searching around, I see people saying to use the PIL import, however it's a bit unclear currently to me, how to achieve this with my requirements.
I also am using Cloudscraper as whenever I would make URL request I would get blocked with a 403 error.
Here is test code:

Answered 2021-Oct-14 at 23:59sg.Image only supports PNG and GIF formats and since the image is jpg you have to convert it to png and for this you can use PIL:
QUESTION
I used cloudscraper to scrape this website oddschecker. I ran it locally on my computer, it works fine. But when I used a Digital Ocean VPS, Cloudflare denied my access, with an error message saying:
Access deniedThis website is using a security service to protect itself from online attacks.
I'm not sure what that means - is Cloudflare blocking my VPS's IP address? Do I have to use a proxy to scrape it?
...ANSWER
Answered 2021-Oct-13 at 06:38Yes, this error you are seeing is due to a Cloudflare firewall rule that you are hitting. The Cloudflare firewall has a list of 20 different triggers to block/allow requests so it's hard to say exactly if is the IP trigger that's being blocked in this case but that's generally the case. See some examples here.
If you are not even able to access the site from the beginning using a new IP address/VPS, it's possible the trigger has to do with the behaviour of your request rather than the source - e.g. rate limiting (although the error message would be different in this case), number of requests per minute, method used to access, reputation of network block (ASN) etc.

Answered 2021-Aug-03 at 10:10It doesn't seem a problem from the scraper but with the server when dealing the negotiation for the connection.
