i tried to get spoify audio with WidevineProxy2, but failed.

it seems WidevineProxy2 cannot grab the license url in spotify chrome web.

so tried with pywidevine with authorization and client-token in python headers, but also failed. it shows "401 Client Error"

can i get some tips?

thanks in advance.

No Spotify-specific tools are needed if you want to get the audio file from the web version. Here is a screenshot of Chromium + audio request opened in DevTools + OpenWV output with the key for it (WidevineProxy2 works too). Just make sure you use a CDM from a physical device, because emulated ones are rejected.

oh yes, you can find all data from network tab. and get the key
just for some tracks it's possible do this. and easy to do

no more convenient if your playlist is 100 tracks or more ... for that better use some tools
however the tool mentioned above, is not available now. so the trick from network tab that's a good suggestion

Edit:

on windows browser (for me at chrome) it isnt needed download through hls converted from json.

Look at F12 Network, there you will find files which come from https://audio-ak.spotifycdn.com/audio. That are the encrypted file as m4a. Download them and decrypt them with the key.

The kid;key you can get with your tool WVProxy2, but it must be a .wvd from a physical device not an emulated.

thats the easiest method.
