Fixed cf new challenge solution #373

Sraq-Zit · 2020-06-20T01:44:51Z

There was mainly 3 problems:

Value of jschl_vc token was taken from commented input element instead of the actual one
The value of the div element with its ID as the variable k is split into multiple divs and numbered at the end of the ID for each div
node: setInterval not defined. I removed that part from js code

Tested on:

EDIT
As of yesterday the tested websites are no more working, due to the new cf challenge.
The challenge lies within the script at the path that goes like example.com/cdn-cgi/challenge-platform/orchestrate/jsch/v1
Once the script is loaded and executed, the function _cf_chl_enter() is called.

I will try and see if I can automate the same process in python

I'm getting a failure when I install from your fork:

I'm going to try to manually run node and see if its output provides any clue as to why it's bombing out, will report back with results

Reinstall it through this fork

            challenge, ms = re.search(

It still don't work with me . Can you test this site ?
https://tubortaxdeal.com
https://www.aichoai.com

weird, the JS on those 2 sites looks really different, like it's not even minified or something. I wonder if they're using a different version of the cloudflare protection stuff?

It was added just recently for the websites I tested.
Thanks !

I see cloudflare has updated again the default challenge for uam

F170x · 2020-07-30T13:37:36Z

Doesn't work with: https://www.pexels.com/search/man/?format=js&seed=&page=2&type=
I don't know how to cloudflare detect between browser incognit mode and a python script, maybe with a difference in the headers or in the ssl protocol version?

jaeakle · 2020-08-12T02:40:54Z

Did Cloudflare change again?
Im getting the error with this line as usual:
r"s,t,o,p, b,r,e,a,k,i,n,g,cpo,f.+?\r?\n[\s\S]+?a\.value\s*=.+?)\r?\n"

Hi, I got a workaround for the problem. get signed up to "scrapingant.com" and use its API (it will produce unique key) to scape the websites behind cloud flare. Thanks, Nag
