Extracting the ID or ULR of an Album_Art about yamaha-nodejs

[MarkusMas]

I finally made some progress but i'm stuck again..

I added this to simpleCommand.js to extract the URL:
Yamaha.prototype.getPlayInfo = function() { var command = '<YAMAHA_AV cmd="GET"><SERVER><Play_Info>GetParam</Play_Info></SERVER></YAMAHA_AV>'; return this.SendXMLToReceiver(command).then(xml2js.parseStringAsync); };

Yamaha.prototype.getShortAlbumArtURL = function() { return this.getPlayInfo().then(function(info) { var PlayInfo = []; var PlayInfoXML = info.YAMAHA_AV.SERVER[0].Play_Info[0].Album_ART[0].URL[0]; return PlayInfoXML; }); };

Now i can print th URL to the Console with this code:
yamaha.getShortAlbumArtURL().then(function(result){ console.log("Short URL is:"+result); })

But if i want to add the IP Adress:
var ShortAlbumArtURL = yamaha.getShortAlbumArtURL() var FullAlbumArtURL = 'http://' + yamaha.ip + ShortAlbumArtURL; console.log(FullAlbumArtURL);

The output of the console is:
http://192.168.178.39[object Promise]

All calls return promises, not the actual result, it should be probably something like this.

yamaha.getShortAlbumArtURL().then(function(url) {
    var FullAlbumArtURL = 'http://' + yamaha.ip + url; 
    console.log(FullAlbumArtURL);
})

Thank you for helping on that very basic level. That writes the full URL to the console :)

How do i manage to have the FullAlbumArtURL available outside this function?!

My goal is to have a module that returns the full URL to another function.

module.exports.GetImageUri = function(deviceid) {
return yamaha.getShortAlbumArtURL().then(function(URL) {
var FullAlbumArtURL = 'http://' + yamaha.ip + URL; console.log(FullAlbumArtURL);
})
};

But the image is then undefined?

[PSeitz]

promises are async, it's not possbile to get the result in a sync manner, you have to use then() like this

GetImageUri().then(function(uri) {
// the result returns
})
