any demo code for lua socket

vitalitymobile · June 2012

Hi everyone,
I found that gideros support luasocket but can not find a demo code to implement this.
So can you show some line of code to using this feature (Open socket and send some bytes to server)
And about websocket, is gideros support for websocket?
Thanks!

Add /All Plugins/LuaSocket/Source/socket.lua to your project.
Now you can use sockets, example (download Google's robots.txt file using HTTP GET method):

local socket = require("socket")
client = socket.connect("google.com", 80)
client:send("GET /robots.txt HTTP/1.0\r\n\r\n")
while true do
  s, status, partial = client:receive(1024)
  print(s or partial)
  if status == "closed" then 
    break 
  end
end
client:close()

You can also add and use FTP, SMTP, etc.

Note: To use WebSocket you'll need to implement the WebSocket protocol using LuaSockets.

And google is your friend too

Btw. welcome on the forum.

Ah one more question, how can i using socket to send byte arrays? :P

Ah one more question, how can i using socket to send byte arrays? :P

In my last post I gave you a basic example of how to do it; how to make a connection with a server, send and receive "byte arrays".
Just use strings, in Lua a string is nothing more than an array of bytes. So if you need to send a table, for example, serialize it in a string.

Thanks Javi,
Let me tell more detail about my purpose:

I plan to communicate with Cubeia Firebase server:

http://www.cubeia.org/index.php/component/content/article/1

So in protocol i thinks it must truly send bytes data:

https://docs.google.com/document/pub?id=1-FWLsdxkkvuf1zdvSCZINCkevHaVzkBC2F_WO2E1vpc#h.y0pg3rtwt1g1

So can you show me some way to do this
Thanks!

You'll need to implement the Firebase protocol, it seems to be simple, based on packets [total_size_of_the_packet, type_id, arguments...] for each operation/request.

To build the packets you'll need to serialize integers in big-endian format.
Download and add to your project "numberlua.lua" to be able to perform bit-wise operations.
https://github.com/davidm/lua-bit-numberlua

Something like this should work:

local bit32 = require "numberlua".bit32
 
-- Integer 32 bit serialization (big-endian)
function serializeInt32(value)
  local a = bit32.band(bit32.rshift(value, 24), 255)
  local b = bit32.band(bit32.rshift(value, 16), 255)
  local c = bit32.band(bit32.rshift(value, 8), 255)
  local d = bit32.band(value, 255)
 
  return string.char(a, b, c, d)
end
 
 
-- Base function to build Firebase packets
function packet(body)
  local size = #body + 4
 
  return serializeInt32(size) .. body
end
 
 
-- Example, function to build VERSION packets (type_id = 0)
function versionPacket(game_id, operator_id, protocol_version)
  local body = string.char(0) .. serializeInt32(game_id) .. serializeInt32(operator_id) .. serializeInt32(protocol_version)
 
  return packet(body)
end
 
-- More functions to create the rest of the packets, type_id=1, type_id=2...
(...)
 
 
-- <version_packet_str> is the packet serialized as a string
local version_packet_str = versionPacket(123, 456, 1)
(...)
local response_packet_str = sendPacketToFirebaseServer(version_packet_str)
(...)

You're welcome

Hi Javi,
I'm implement protocol and in sendPacketToFirebaseServer, i try this:

function sendPacketToFirebaseServer(version_packet_str)
client = socket.connect("localhost", 4123)
client:send(version_packet_str)
while true do
s, status, partial = client:receive(1024)
print(s or partial)
if status == "closed" then
break
end
end
client:close()
return "done";
end

But the player become not response (Server work well)

So can you show me the right way to receive server response?

And can you please show me how to pack String argument?
(example login request : https://docs.google.com/document/pub?id=1-FWLsdxkkvuf1zdvSCZINCkevHaVzkBC2F_WO2E1vpc#id.l9sgb8g2sp39)

I don't use/know Firebase but I suppose that first you need to send a login request packet to the server.

function serializeInt16(value)
  local a = bit32.band(bit32.rshift(value, 8), 255)
  local b = bit32.band(value, 255)
 
  return string.char(a, b)
end
 
function int32(str)
  return string.byte(str, 1) * 16777216 + string.byte(str, 2) * 65536 + string.byte(str, 3) * 256 + string.byte(str, 4)
end
 
function int16(str)
  return string.byte(str, 1) * 256 + string.byte(str, 2)
end
 
function stringLuaToStringFirebase(lua_str)
  return serializeInt16(#lua_str) .. lua_str
end
 
function stringFirebaseToStringLua(firebase_str)
  return string.sub(firebase_str, 3, int16(firebase_str) + 2)
end
 
function stringLuaToArrayFirebase(lua_str)
  return serializeInt32(#lua_str) .. lua_str
end
 
function arrayFirebaseToStringLua(firebase_str)
  return string.sub(firebase_str, 5, int32(firebase_str) + 4)
end
 
function typeOfPacket(packet)
  if packet == nil or #packet < 6 then
    return nil
  end
 
  return string.byte(string.sub(packet, 5))
end
 
function loginRequestPacket(user, password, operator_id, credentials)
  local body = string.char(10) .. stringLuaToStringFirebase(user) .. 
              stringLuaToStringFirebase(password) .. 
              serializeInt32(operator_id) .. 
              stringLuaToArrayFirebase(credentials)
 
  return packet(body)
end
 
function printLoginResponsePacket(packet)
  local pos = 6
 
  local screen_name = stringFirebaseToStringLua(string.sub(packet, pos))
  pos = pos + #screen_name + 2
 
  local pid = int32(string.sub(packet, pos))
  pos = pos + 4
 
  local status = string.byte(string.sub(packet, pos))
  pos = pos + 1
 
  local code = int32(string.sub(packet, pos))
  pos = pos + 4
 
  local message = stringFirebaseToStringLua(string.sub(packet, pos))
  pos = pos + #message + 2
 
  local credentials = arrayFirebaseToStringLua(string.sub(packet, pos))
 
  print("Screen name: " .. screen_name)
  print("PID: " .. pid)
  print("Status: " .. status)
  print("Code: " .. code)
  print("Message: " .. message)
end
 
function sendPacketToFirebaseServer(packet)
  client = socket.connect("127.0.0.1", 4123)
  client:send(packet)
  local response_packet = ""
  while true do
    local s, status, partial = client:receive(1024)
    local str = s or partial
    if str then
      response_packet = response_packet .. str
    end
    if status == "closed" then 
      break 
    end
  end
  client:close()
 
  return response_packet
end
 
local login_packet_request = loginRequestPacket("username", "password", 123, 456)
local response_packet = sendPacketToFirebaseServer(login_packet_request)
if typeOfPacket(response_packet) == 11 then
  printLoginResponsePacket(login_packet_response)
else
  (...)
end

PD: Do not print directly the response packets, unpack them (see printLoginResponsePacket(...) as an example).

Thanks Javi for more detail function.
When server receive packet, it show hex dump
00 00 00 16 0A 00 06 74 69 6E 68 6C 68 00 03 31 32 33 00 00 00 7B
And do not accept message.

I forgot to write the credentials in quotes:

local login_packet_request = loginRequestPacket("username", "password", 123, "456")

If the problem persists try excluding the size of the first field:

-- Base function to build Firebase packets
function packet(body)
  local size = #body
 
  return serializeInt32(size) .. body
end

vitalitymobile · June 2012

Hi Javi,
I try as you comment but it still cause error.
For detail and debug information, i send you Server code and Client Code.
To start Server, go to pom.xml file folder and type maven command: mvn firebase:run
(No Database and Setup require)
Many Thanks!

It works, the problem was you used stringLuaToStringFirebase(credentials) instead of stringLuaToArrayFirebase(credentials).

The server doesn't close the connection so I've modified also sendPacketToFirebaseServer(...).

function packet(body)
  local size = #body + 4
 
  return serializeInt32(size) .. body
end
 
function loginRequestPacket(user, password, operator_id, credentials)
  local body = string.char(10) .. stringLuaToStringFirebase(user) .. 
    stringLuaToStringFirebase(password) .. 
    serializeInt32(operator_id) .. 
    stringLuaToArrayFirebase(credentials) -- This is an ARRAY!
 
  return packet(body)
end
 
function sendPacketToFirebaseServer(packet)
  client = socket.connect("127.0.0.1", 4123)
  client:send(packet)
  local response_packet = ""
  while true do
    local s, status, partial = client:receive(1)
    local str = s or partial
    if str then
      response_packet = response_packet .. str
    else
      response_packet = nil
      break
    end
    local response_packet_size = #response_packet
    if response_packet_size > 4 then
      if response_packet_size == int32(response_packet) then
        -- OK, packet received
        break
      end
    end
    if status == "closed" then 
      response_packet = nil
      break 
    end
  end
  client:close()
 
  return response_packet -- Note: if any problem response_packet == nil
end
 
local login_packet_request = loginRequestPacket("tinhlh", "123", 123, "456")
local response_packet = sendPacketToFirebaseServer(login_packet_request)
local type_of_packet = typeOfPacket(response_packet)
if type_of_packet == nil then
  print("Connection error!")
elseif type_of_packet == 11 then
  printLoginResponsePacket(response_packet)
else  -- Rest of packets...  elseif type_of_packet == X then (...)
  print("Type of packet received: " .. type_of_packet)
end

Now just follow the protocol and implement the rest of the packets, ok?

An example on how to comms using sockets to an OAuth 2.0 systsem would be great, this way we could login to Facebook, Twitter and loads more online systems.

vitalitymobile · June 2012

Wow wow!
It works like a charm!
Thanks Javi so much for your Patient support!
I've updated client code and share to community (http://www.giderosmobile.com/forum/discussion/1098/complete-code-client-server-for-building-multiplayer-game)

Hi guys!
I'm trying to create basic luasocket project.
How to fix this error? It seems that a file is missing, though I'm using Gideros 2018.6.2, everything should be there. All plugin files are present in C:\Program Files(x86)\Gideros\All Plugins\luasocket
(I've enabled plugin "Lua Socket" in my project's settings)
All I have in my 'main.lua':

local socket = require("socket")
client = socket.connect("google.com", 80)
client:send("GET /robots.txt HTTP/1.0\r\n\r\n")
while true do
	s, status, partial = client:receive(1024)
	print(s or partial)
		if status == "closed" then 
			break 
		end
end
client:close()

Console error:
