Trying to decode this json string but without success.

Should it be something like this?

Yes, at least according to me.

By the way, do you know if you can create global functions in a scene? To only be used by local calls from other scenes.

Like this.

Scene1:

--[[

%% properties

%% globals

--]]

global function updateDevice(deviceId, successCallback, errorCallback)

local http = net.HTTPClient()

http:request('http://127.0.0.1:11111/api/devices/' .. deviceId, {

options = {

method = 'GET'

},

success = successCallback,

error = errorCallback

})

end

Scene2:

--[[

%% properties

%% globals

--]]

deviceId = updateDevice(1, function(resp)

print("Status: " .. resp.status)

local d = json.decode(resp.data)

print(d.name)

end,

function(err)

print('error' .. err)

end

)

btw, if you get nothing... try index 1

its the square brackets at first and last position that gives error.....

[KristianO 15]

Sure, but it was just an example. Is it possible to create like "global" scene like scene1 only carrying global functions to be called from separate scenes?

[jompa68 121]

Need to remove first and last brackets.

There are several issues with the json.decode function. It won't decode a json string which uses backspace as escape character - it just returns an error (and it doesn't even return the right error). I've been trying to inject some data into a virtual device with some lua in it. In the json format, the lua code is riddled with escape characters so it is impossible to avoid - and I can't make this scene run in any way (except constructing an array which is 17 miles long) because json.decode wont transform the data into an array.
