Remote control of Philips TV with json - baggins - 29.12.2016

Hi,

I'm trying to write a script to control a Philips TV with json.
Based on an example in thread: http://forum.logicmachine.net/showthread.php?tid=509&highlight=POST

I'm trying the following:

Code:
require('json')
require('socket.url')
require('socket.http')

fields = {key = "CursorLeft",}
data = json.encode(fields)
print(data)
post = 'data=' .. socket.url.escape(data)
print (post)
ip = '192.168.0.232:1925'

res, err = socket.http.request('http://'.. ip .. '/1/input/key', post)

print(res)
print( err)

This fails:

Code:
{"key":"CursorLeft"}
data=%7b%22key%22%3a%22CursorLeft%22%7d
<html><head><title>Bad Request</title></head><body>Bad Request</body></html>
400

Philips TV use Jointspace. Manual page for POST: http://jointspace.sourceforge.net/projectdata/documentation/jasonApi/1/doc/API-Method-input-key-POST.html

Any tips?

Can you check if any GET methods are working?

After a long session with Wireshark I gave up on this script...

I now use the following script which works:

Code:
require('json')
require('socket.url')
require('socket.http')
local ltn12 = require("ltn12")

path = "http://192.168.0.232:1925/1/input/key"
local payload = [[{"key" : "CursorLeft"}]]
print(payload)
local response_body = { }
 local res, code, response_headers, status = socket.http.request
  {
    url = path,
    method = "POST",
    headers =
    {
          ["Content-Type"] = "application/json",
          ["Content-Length"] = payload:len()
    },
   source = ltn12.source.string(payload),
   sink = ltn12.sink.table(response_body)
  }

print('Response: = ' .. table.concat(response_body) .. ' code = ' .. code .. '   status = ' .. status,1,'Sample POST request with JSON data',-1)

Probably it didn't work without proper Content-Type header.
