Title: MCWS Help Please
Post by: Striker on February 11, 2024, 05:36:49 pm

Hi, I'm trying to get some of the MCWS commands working.  I currently am running v30 so I can't test this myself.  I'm working on an alternative to my use of the PlayingNow plugin which only works on the 32 bit version of MC.  If I can get the info I need using MCWS then I can give up the PlayingNow plugin and I'd purchase MC 32.

For the v31 command: http://127.0.0.1:52199/MCWS/v1/Playback/Info?Fields=Genre

Can I query for user fields too?

Can I query for the next track fields?  (PlayingNow lets me select fields like "next.artist")
If not, then I guess I could query for the NextFileKey using GetInfo, but it's not working for me.

This does not work for me:

http://localhost:52199/MCWS/v1/Playback/GetInfo?File=54404   // which is a valid key

There's no parameter file for getinfo, keys is the right parameter for that call

the quoted doc is for a different API so it's not entirely clear what you are trying to ask though

http://localhost:52199/MCWS/v1/Playback/GetInfo?Keys=54404

doesn't work for me either.  Is this a valid MCWS command for MC v30?

This does work for me.

http://localhost:52199/MCWS/v1/Playback/Info?Zone=-1

I'm trying to get info about the current and next track and the playback status.

It's Files/GetInfo so you need to read the doc more carefully to make sure you have the right URL, use the example link if in doubt then copy that

/File/GetInfo to get info about a specific file:
http://localhost:52199/MCWS/v1/File/Getinfo?File=54404&Action=json

/Playback/Info gives you the current and next file being played:
http://localhost:52199/MCWS/v1/Playback/Info

You can use /Playback/Playlist to get all files in the current playlist too.
http://localhost:52199/MCWS/v1/Playback/Playlist?ActiveFileOnly=1&Action=json&Fields=Name,Album,Artist,Genre

(bug? it looks like ActiveFileOnly=1 returns all files in playlist if there's nothing playing, instead of an empty list)

If you set ActiveFileOnly, you need to also set ActiveFile.

Thank You for the reply.

/Playback/Info gives you the current and next file being played:
http://localhost:52199/MCWS/v1/Playback/Info

For the v31 command which adds the Fields keyword: http://127.0.0.1:52199/MCWS/v1/Playback/Info?Fields=Genre [;...]

Can I query for user fields too?

Can I query for the next track fields?  (PlayingNow lets me select fields like "next.artist")

No, you can't get Field info for the next file like that.
You first need to call /Playback/Info with no parameters, and that gives you the current FileKey and the NextFileKey:

http://localhost:52199/MCWS/v1/Playback/Info
Response:
(...)
<Item Name="FileKey">44809</Item>
<Item Name="NextFileKey">121604</Item>
(...)

Then you call /File/GetInfo for each of those keys to get all the field values (or just the ones you need) for each of them:
http://localhost:52199/MCWS/v1/File/Getinfo?File=44809&Action=json
http://localhost:52199/MCWS/v1/File/Getinfo?File=121604&Action=json

You can at least save one call by adding the fields to the first call

Agree... but...

For the v31 command which adds the Fields keyword: http://127.0.0.1:52199/MCWS/v1/Playback/Info?Fields=Genre [;...]

Can I query for user fields too?
