c++编写node的addon(5) --object 工厂

1.环境

Ubuntu 14.04

node 4.5.0

node-gyp 3.4.0

2.项目

新建项目，加入组件nan和bindings

方法一、在项目文件的node_modules中复制组件nan和bindings的全部代码包;

方法二、在package.json的dependencies中加入这两个组件，用nmp安装

3.c++源码

//addon.cc#include <nan.h>void CreateObject(const Nan::FunctionCallbackInfo<v8::Value>& info) {	v8::Local<v8::Object> obj = Nan::New<v8::Object>();	obj->Set(Nan::New("msg").ToLocalChecked(), info[0]->ToString());		info.GetReturnValue().Set(obj);}void Init(v8::Local<v8::Object> exports, v8::Local<v8::Object> module) {	module->Set(Nan::New("exports").ToLocalChecked(), Nan::New<v8::FunctionTemplate>(CreateObject)->GetFunction());}NODE_MODULE(addon, Init)4.binding.gyp
{	"targets": [		{			"target_name": "addon",			"sources":["addon.cc"],			"include_dirs":[				"<!(node -e /"require('nan')/")"			]		}	]}5.js源码
//addon.jsvar addon = require('bindings')('addon');var obj1 = addon("hello");var obj2 = addon("world");console.log(obj1.msg + "  === " + obj2.msg);6.编译addon
cd到源码目录下
node-gyp configure build 7.执行
cd 到源码目录下
node hello.js
