[Userscript] KaniWani audio


#22

Right you are: merged PR. @henshin5 try updating the script and see if it works for you now.


#23

Unfortunately this script seems to no longer work. :confused:


#24

Yeah, this stopped working like right after I started using it in the past two weeks or so. I think I heard it working once and now it no longer works.

Anyone know why maybe?


#25

Depends on how it’s trying to pull audio from Wanikani.
Once API V2 is stable and WK have released their audio publicly (technically this script is using WK’s resources without permission) we’ll be adding it to Kaniwani anyway.


#26

FYI this definitely won’t work at the moment on KW 2.0 since all the markup/html content has changed.


#27

Aw man, I just added it to the API and Third Party Apps list yesterday


#28

Sorry for not replying sooner, I’ve been travelling. I’ll have a look when I get a chance (and when I’ve finished my reviews :-O).


#29

Hi, thanks for creating this script, I was really glad it was available. :slight_smile:
I tried getting it to work again but I think I’m stuck at a point where you would have to look into it. It generates a URL that seems to be valid, such as https://wanikaniaudio.herokuapp.com/url/王 and returns an AWS URL but I get an AccessDenied exception for that AWS content.

Changing the script wasn’t much work but since you are busy too I thought maybe it helps to share my changes. Not sure if that was all that had to be changed since I didn’t look any further after being unable to load the mp3 file.

They also switched to https (or maybe it has always been that way) which causes problems at least for the loading image.

Following this thread for updates


#31

Sorry, I’ve had several goes at trying to get the script to work after the changes to both KaniWani and WaniKani and I haven’t been able to figure anything out. The script will probably stay broken indefinitely, unless there’s yet more major changes.


#32

Can you get the audio from jisho.org instead of wanikani?
