domoticz.openURL with JSON to control Kodi volume

[hkemal]

Hello all,

I have this
"curl -H "Content-type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"Application.SetVolume","id":1,"params":{"volume":80}}' http://192.168.1.4:8080/jsonrpc"
in a bash script and I am using os.execute out of dzVents to set the volume on my Kodi.

I would like to use domoticz.openURL to do the volume setting directly but can not get it to work.

This is what I did, but domoticz doesn't like it. Something about postData is not formated properly.

domoticz.openURL({
url = 'http://192.168.1.4:8080/jsonrpc',
method = 'POST',
postData = {"jsonrpc":"2.0","method":"Application.SetVolume","id":1,"params":{"volume":80}}
})

Any ideas?

Regards
Kemal

Hello,

I tried it.
Domoticz doesn't give any error but Kodi is not reacting. Volume does not get changed.

Maybe Kodi returns some error code, how can I catch this?

Hi,
Who can help.
I have created and tested a curl command and want to use this inside domoticz lua but can't get it to work.
This is my curl command (private info removed). I tested this with git bash
curl -X PUT --data '{"on":false}' http://192.168.100.128/api/<removed>/gr ... mer/action
This will switch of the light from HUE
This is my lua translation. It doesn't show errors but isn't working
os.execute ('curl -X PUT --data "{on:false}" http://192.168.100.128/api/<removed>/gr ... mer/action')

Ok that at least confirms Kodi does. So it must be something related to the method POST . Maybe you need to add something in the header part like this ?

                        }, 

            logging =   {   
                            level            =  domoticz.LOG_DEBUG,   
                            marker           =  "kodiResponse Test" 
                        },

Hello,

sorry for the delay, I executed it now.
Kodi gives a parse error back.

[waaren]

sorry for the delay, I executed it now.
Kodi gives a parse error back.

I expect that is something to do with quotes disappearing between domoticz and Kodi but cannot test as I do not own one. What you could try is escaping the quotes with a backslash so ' would become \' and " would become \"

[hkemal]

I had to do some escaping and forming of the data to match my syntax in curl, but this finally did the trick

testStrings[1] = "{\"jsonrpc\":\"2.0\", \"method\":\"Application.SetVolume\", \"id\":1, \"params\":{\"volume\":80}}"

Thank you!!
