Using windows 10 pro and python 2

Udemy has implemented a validation for automation tools.
the picture shows the html code that is returned of udemy when the udemy-dl tool tries to get the login form.

I do not know what we need to do, but you can count on me to try to find a solution. My email is Linneu.[email protected].

The solution could be to encapsulate the script into a chrome extension to use the chrome's cookies and fingerprint ... ?

[linneudm]

See if this solution was found at #98 . It worked for me.

@trash-anger can you please explain a bit more?

@coder797 i already have given the solution in issue #98 and it works fine for me i have tested with py2 & py3 both on windows 7,windows 8.1, windows 10, mac osx 10.9.5.
have a look of windows 10 POC. it works fine.

Steps to patch.

• sudo pip install requests --upgrade
• sudo pip install unidecode --upgrade
• sudo pip install requests[security] --upgrade
• done

i 'm closing this issue as duplicate now.

It seams that udemy is trying to avoid users to download automatically a course by adding a captcha.

It would be a good idea to create a browser extension to rather than use a directly the python script and to replace std_headers by the user's real user-agent.

Doing this way, we maybe could distribute udemy-dl to a larger users population and we could especially use different fingerprints for each udemy-dl users.

And maybe using pyjs, it won't be to much work to do !

Thanks - solution did work for me.

@r0oth3x49 Hi those 3 pip commands didn't resolve the login issue in windows 7.
The same error message appears:

Trying to log in ...
Exception

Today the download worked - udemy-dl logged in to udemy account & downloaded the course,.Don't know why it didn't work 10 days ago after the pip updates.

Try with this -> https://www.npmjs.com/package/udemy-dl

-> npm install -g udemy-dl
-> udl https://www.udemy.com/COURSE_NAME

its working with python 3

Today the download worked - udemy-dl logged in to udemy account & downloaded the course,.Don't know why it didn't work 10 days ago after the pip updates.

is it still working now ?

[r0oth3x49]

it is working but some time when some one tries to download things like a robot then udemy appears with the captcha. The solution for that is using cookie based method instead

[ademianfight]

Should i subscribe the course first? I've succeeded to download the
subscribed course but not for the course that i want to have it.

the tool will only download subscribed courses.
