thatmusic API

This is a workaround to use private VK music API. Inspired by datmusic-api.

How it works

The app uses token from environment variable. It searches songs with given query in VK private api and saves data in cache.

For every search query the app returns downloading links. On download request the app downloads file, caches it and then sends to client.

Auth

VK's private audio API's can only be used with tokens from official apps or special third party apps (for ex. Kate mobile). User agent of that app must be used when talking to VK when using such tokens.

This is how you can get tokens using Kate Mobile app:

Use proxy to intercept HTTPS requests made by Kate Mobile app. Example apps: mitmproxy, Fiddler, Charles proxy, or Wireshark
Listen for requests to get refreshToken After Kate's login, VK will give an access token: this token won't work with Audio API's ("Token confirmation required"). Open Audios screen from the app, and you will see in your network interceptor that Kate will get Token confirmation required from VK. After which Kate will register something in Google Cloud Messaging to generate receipt field which will it use to get refreshToken by sending it to private API auth.refreshToken along with current token. After all, auth.refreshToken will return a new token. This is the token you need to save to be able to use it in this branch.

Note: Try to use same IP's while doing it all.

Search

Search results are cached for 24 hours by default.

Downloads & Streams

https://thatmusic.example/dl/{search_hash}/{audio_hash} (downloads with proper file name Artist - Title.mp3)

https://thatmusic.example/id/{owner_id}/{audio_hash} (downloads with proper file name Artist - Title.mp3 using VK owner and audio id)

https://thatmusic.example/stream/{search_hash}/{audio_hash} (streams file)

Cache

Mp3 urls for VK are valid only for 24 hours. So search results can be cached only for 24 hours.

Default caching driver is memory for search results and dbm for songs data. You can change this behaviour in settings file. See Beaker docs for additional info.

Using with S3 Storage

Not supported yet

Deployment

Project configured to run in docker container.

Install docker & docker-compose
Create your own .env by coping default env file and specify container port or you can use environment variable CONTAINER_PORT when running container
Place vk access token in your .env, or use environment variable ACCESS_TOKEN (see default env).
Run docker-compose -p YOURPROJECTNAME up --build -d
The app will be available at your machine on the specified earlier port. For example, curl "http://localhost:8000/search/?q=Moby".
