Accessing Spotify Metadata API from within a Spotify app?

Question

I want to run Spotify searches from within a Spotify app (to find tracks for an artist, for which I do not have a Spotify URI, only the name).

I have not found func

Answer 1

This is not the finest way to solve your problem. There is a direct API for searching within your app. See Juan's solution.

But you could also talk to ws.spotify.com directly when you add the domain to your app's manifest.json.

"RequiredPermissions": ["http://ws.spotify.com" ]

e.g. http://ws.spotify.com/search/1/track.json?q=kaizers+orchestra, see their Developer Site. The response contains the header "Access-Control-Allow-Origin: *", so you should be able to query from within your app.

You can use sp.core.search

sp.core.search("query",
    {onSuccess: function(result) {
        // parse result
        }
    }
);

sp.core.getMetadata if you have the uri

    sp.core.getMetadata("uri", {
        onSuccess: function(data){
            console.debug(data);
        },
        onFailure: function(){
                //...
        },
    });
