LuaSocket简单使用

版本：LuaSocket 3.0-rc1

限制：只能收发字符串，且接收的字符串必须以 \n 结尾。

客户端cocos2dx-lua 3.14.1

local MainScene = class("MainScene", cc.load("mvc").ViewBase)
function socketInit()  
    local socket = require("socket")
    print(socket._VERSION);
    local host = "127.0.0.1"  
    local port = 10001;  
    G_SOCKETTCP = socket.tcp()  
    local n,e = G_SOCKETTCP:connect(host, port)  
    print("connect return:",n,e)  
    G_SOCKETTCP:settimeout(0)  
end  
function socketClose()  
    G_SOCKETTCP:close()  
end  
function socketSend(sendStr)  
    G_SOCKETTCP:send(sendStr)  
end  
function socketReceive()  
    local response, receive_status=G_SOCKETTCP:receive()  
    print("receive return:",response or "nil" ,receive_status or "nil")  
    if receive_status ~= "closed" then  
        if response then  
            print("Receive Message:"..response) 
        end  
    else  
        print("Service Closed!")
    end  
end 

function MainScene:onCreate()
    socketInit()  
    local delay = 0  
    local function receiveHandler(dt)  
        delay = delay + dt  
        if delay > 0.1 then  
            socketReceive()  
            delay= 0
        end  
    end
    self:scheduleUpdateWithPriorityLua(receiveHandler,1)
    socketSend("asdf")
end

return MainScene

服务端：java netty 

childhandler中加入继承SimpleChannelInboundHandler的处理器，StringEncoder与StringDecoder处理器。

在发送字符串时，在末尾加\n后发送给luasocket客户端。

亲测可用。

性能未知。
