...
        output_dir = '%s/../runtime-src/Classes/auto' % project_root

        cmd_args = {
                    'cocos2dx_socket_util.ini' : ('cocos2dx_socket_util', 'lua_cocos2dx_socket_util_auto'), \
                    }
...

端末を開きgenbindingsに入りますsocket_util.pyが存在するディレクトリで、次のコマンドを実行してコードを生成します.
1

./genbindings_socket_util.py

エラーが報告されているかどうかを確認し、エラーが報告されていないことはコード生成に成功したことを示します.
三、特殊関数のバインドコードを書く
SocketUtilには2つの特殊な点の関数が含まれており、Luaから1つの関数の参照を渡す必要があり、C++に手動でバインドする必要があります.
Autoフォルダがあるディレクトリに新しいフォルダmanualを作成し、次のコードをコピーします.

    register_all_cocos2dx_socket_util(stack->getLuaState());
    register_all_cocos2dx_socket_util_manual(stack->getLuaState());
    ...
}

五、テスト
src/app/scenesの下にあるMainSceneを開きます.lua

    instance:addMsgHandlerLua(handler(self, MainScene.msgHandler))
    instance:addStateHandlerLua(handler(self, MainScene.stateHandler))
    instance:connectServer("127.0.0.1", 3000)
    scheduler.performWithDelayGlobal(function(dt)
            local str = "hello world"
            instance:sendMsg({string.byte(str,1,#str)})
        end, 2)
    scheduler.performWithDelayGlobal(function(dt)
            instance:close()
        end, 4)
end

function MainScene:msgHandler(bytes)
    print("msg")
end

function MainScene:stateHandler(connected)
    print("state: "..tostring(connected))
end

サービス・エンド・プログラムの起動、実行、コンソール出力の確認

[LUA-print] state: true
[LUA-print] msg
[LUA-print] state: false

これでSocketUtilのLuaへのバインドが完了します.
