Application Store documentation and sample app

[Erwin van der Zwart]

Hi Pawel,

I created a small HTTP API (as .lp) for you to save and get data from storage from javascript:

1) Create a LUA script and run once to create the storage.lp file that will act as HTTP API:

dst = '/www/user/storage.lp'

io.writefile(dst, [[<? 
require('apps')
require('socket.url')
action = socket.url.unescape( getvar('action') or 'none' )
storagename = socket.url.unescape( getvar('storagename') or 'none')
  format = socket.url.unescape( getvar('format') or 'string' )
storagevalue = socket.url.unescape( getvar('value') or '{}')
if action == 'storageset' then
  if storagename ~= 'none' then
  if format == 'json' then
  storagevalue = json.decode(storagevalue)
end
  storage.set(storagename, storagevalue)
  print('value saved to storage as ' .. format)
end
elseif action == 'storageget' then
  if storagename ~= 'none' then
storagevalue = storage.get(storagename)
storagevalue = json.encode(storagevalue)
  print(storagevalue)
end
end
?>]])
script.disable(_SCRIPTNAME)

2) Put this in your custom javascript:

$(function() {

  
  // Save json data to storage with name 'mystoragename1'
  var jsondata = {"name":"Erwin van der Zwart","company":"Schneider Electric","country":"The Netherlands"}
  jsondata = JSON.stringify(jsondata);
  $.get( "/user/storage.lp?action=storageset&storagename=mystoragename1&format=json&value=" + jsondata, function( data ) {
    res = data.trim();
    console.log(res);
  });
  
  // Get json data from storage with name 'mystoragename1'
  $.get( "/user/storage.lp?action=storageget&storagename=mystoragename1", function( data ) {
    res = data.trim();
    res = JSON.parse(res);
    console.log(res);
  });
  
  // Save string data to storage with name 'mystoragename2'
  var stringdata = "Erwin van der Zwart Schneider Electric The Netherlands"
  $.get( "/user/storage.lp?action=storageset&storagename=mystoragename2&format=string&value=" + stringdata, function( data ) {
    res = data.trim();
    console.log(res);
  });
  
  // Get string data from storage with name 'mystoragename2'
  $.get( "/user/storage.lp?action=storageget&storagename=mystoragename2", function( data ) {
    res = data.trim();
    console.log(res);
  });

});

By changing the action / storagename / format / value in the URL you can set and get any value from storage with this script.

BR,

Erwin
