HifiBerry API GET

[Kai-Roger]

Hi.

Now that i have somewhat control over how to POST to the API, i'm having problems understanding how to use GET from the API. I have made a Resident script with 2 sec. sleep interval. The goal is to retrive volume % status on my HifiBerry amplifier, and write it to a group adress.

Code:

http = require('socket.http')
ltn12 = require('ltn12')

Volume_status                = grp.find        ('25/2/12')


--body = require('json').encode({
--  percent = tostring(event.getvalue())
--})

res, code = http.request({
  url = 'http://192.168.1.91:81/api/volume',
    method = 'GET',
headers = {
    ['Content-Length'] = #body,
    ['Content-Type'] = 'application/json',
  },
  source = ltn12.source.string(body)
})

Volume_status            :write(GET_Volume)

log(res, code)

The code above is a mess. Any ideas how to do this?
