We use Yandex Music outside the browser

    Recently, I wanted to work with Yandex Music not through a browser. As it turned out, they did not have an open api, and the case was not trivial. And nothing ready could be found.

    Those who are too lazy to read can immediately go to the result - python-yamusic .

    We analyze the work



    To get started, I armed myself with a firebug and tracked where the requests go. The main directions were found:

    The data received by the first three queries is easy to filter using Beautiful Soup , as:
    • all tracks are in divs with the b-track class with all the data in the onclick property (from here we get its storage dir and id );
    • albums are in divs with the b-albums class ;
    • artists in divs with class b-artist-group .

    You can see my parser implementation in the code .

    Download track



    Now it seems that everything is simple. We make a request to storage.music.yandex.ru/get storage dir of the track /2.xml and get an xml of the form: Now we make a request storage.music.yandex.ru/download-info storage dir of the track / filename of the track and get one more xml'ku: But, having looked at the requests for downloading the track, it became clear that there is not all the data. Scrolling through javascript, I found a function that creates the key we need from the path without the first character and parameter s. This function was too lazy to rewrite in python, so it just runs through QScript. Now, having all the data, you can compile the url of the track: http: // host / get-mp3 / key /





    хост
    путь
    параметр ts
    регион
    параметр s




    the ts parameter is the path ? track-id = id of the track & \ region = region & from = service-search, but you won’t be able to download the file just like that. Without hesitation, I decided to try to do everything in one session - everything worked out right away. The result is a python-yamusic library

    Library usage



    It is very simple, first you need to initiate a Qt application and make all the imports: To search, there is: To get data from the found objects: And, in fact, to open the track: PS & \ region is written because of ®ion
    >>> from yamusic.app import Search, cursor
    >>> from PySide.QtCore import QCoreApplication
    >>> import sys
    >>> app = QCoreApplication(sys.argv)


    >>> cursor.search(Search.TYPE_ARTISTS, 'query')
    >>> cursor.search(Search.TYPE_ALBUMS, 'query')
    >>> cursor.search(Search.TYPE_TRACKS, 'query')


    >>> artist.get_albums()
    >>> artist.get_tracks()
    >>> album.get_tracks()


    >>> track.open()
