A cross-platform Bluesound API for Google Go.
Simple sample code:
import (
"log"
"github.com/ClausRN/BluesoundAPI"
)
var (
mySound BluesoundAPI.BluesoundController
)
mySound = BluesoundAPI.NewBluesoundController("192.168.2.220")
mySound.Start()
syncstat := mySound.SyncStatus()
log.Printf("Brand: %s, Model: %s, Name: %s", syncstat.Brand, syncstat.Model, syncstat.Name)
log.Printf("Player version: %s", mySound.GetVersion())
mySound.ClearPlayQueue()
mySound.SetVolume(20)
mySound.SetShuffle(BluesoundAPI.ShuffleOn)
mySound.SetRepeat(BluesoundAPI.RepeatAll)
mySound.PlayPlaylist("Playlist 1")
mySound.Play()
stat := mySound.Status()
log.Printf("Now playing - Artist: %s, Album: %s, Track %s", stat.Artist, stat.Album, stat.Name)
mySound.Close()Very much work in progress at this time. Much of the work decoding the http api is done by these two guys. A big thank you to them. https://github.com/venjum/bluesound https://github.com/superfell/BluShepherd/blob/master/api.md
Discovery returns a service on port 11000, a look at the node 2 diagnostic output from the app, and some wireshark runs, show this is a HTTP service. Endpoints seem to return xml, or image binary data, and support gzip compression. It unfortuantly doesn't use HTTP all that well [GETs that have side-effects, lack of useful caching headers], no doubt leading to the artwork caching problems in the desktop app.

/SyncStatus returns high level info about the device, e.g.
curl http://192.168.1.45:11000/SyncStatus
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <SyncStatus icon="/images/players/N110_nt.png" volume="-1" modelName="NODE 2" name="Cave" model="N110" brand="Bluesound" etag="3" schemaVersion="15" syncStat="3" id="192.168.1.45:11000" mac="90:56:82:3F:AA:A0"> </SyncStatus>
-
/Status returns detailed information about what the device is currently doing
curl http://192.168.1.45:11000/Status
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <status etag="ab5306d5f830e473252a22f5102df62d"> <album>John Digweed Live in London</album> <artist>Phonogenic</artist> <canMovePlayback>true</canMovePlayback> <canSeek>1</canSeek> <cursor>92</cursor> <fn>/var/mnt/ANDROMEDA-music/iTunes/Music/Compilations/John Digweed Live in London/3-09 Tired Being.m4a</fn> <image>/Artwork?service=LocalMusic&fn=%2Fvar%2Fmnt%2FANDROMEDA-music%2FiTunes%2FMusic%2FCompilations%2FJohn%20Digweed%20Live%20in%20London%2F3-09%20Tired%20Being.m4a</image> <indexing>0</indexing> <mid>10</mid> <mode>1</mode> <name>Tired Being</name> <pid>60</pid> <prid>0</prid> <quality>cd</quality> <repeat>2</repeat> <service>LocalMusic</service> <shuffle>0</shuffle> <sid>15</sid> <sleep></sleep> <song>71</song> <state>play</state> <syncStat>3</syncStat> <title1>Tired Being</title1> <title2>Phonogenic</title2> <title3>John Digweed Live in London</title3> <totlen>170</totlen> <volume>-1</volume> <secs>6</secs> </status>
this also takes an etag querystring param, and timeout value [not an HTTP header], this appears to provide a blocking get until there's a status change.
curl "http://192.168.1.45:11000/Status?etag=1117370c37d450a8322e05f51358a0a4&timeout=60"
-
/Play & /Pause will cause the player to start or stop the current play queue, it returns the new state of the player
curl http://192.168.1.45:11000/Play
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <state>play</state>
specifying an ID parameter will change the song being played, id appears to be a zero based index into the play queue.
-
/Back and /Skip will go backward or forward one track.
-
/Shuffle?state=1 turns shuffle on, state=0 turns it off.
-
/Repeat?state=0|1|2 where 2 = no repeat, 1= repeat 1, 0 = repeat all
-
/Services returns details about the available sources for node, local library, internet radio services etc, this would seem to drive the main part of the UI.
-
/Presets
-
/GitVersion returns the version of the software on the devices? (this returns 2.8.3 for my node 2)
-
/Playlist returns the Play Queue
-
/Clear deletes all the play queue entries
-
/Delete?id=x deletes an entry from the play queue, id is the zero offset into the play queue.
-
/Songs returns more detailed information about an album e.g.
/Songs?service=LocalMusic&album=Waiting%20for%20the%20Sirens%27%20Call&artist=New%20Order
returns
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<album time="3804" quality="cd">

</song>
<song>-
/Add adds items to the play queue and starts them, e.g.
Play Now
/Add?playnow=1&where=nextAlbum&service=LocalMusic&album=%2A%2A%2Ak%20the%20Millenium&artist=The%20KLFAdd Next
/Add?playnow=-1&where=nextAlbum&service=LocalMusic&album=Vs.%20T-World%20-%202000&artist=GusGusPlay Last
/Add?playnow=-1&where=last&service=LocalMusic&album=Waiting%20for%20the%20Rights%20of%20Mu&artist=The%20KLF -
/Artwork returns the cover artwork for a specified album/artist,
