NodeJS开发c++扩展模块

建立测试模块代码FaceRecognition.cpp

#include <node.h> using v8::FunctionCallbackInfo; using v8::Isolate; using v8::Local; using v8::Object; using v8::String; using v8::Value; void CAMOpen(const FunctionCallbackInfo<Value>& args) { Isolate* isolate = args.GetIsolate(); args.GetReturnValue().Set(String::NewFromUtf8(isolate, "cam_open...")); } void init(Local<Object> exports) { NODE_SET_METHOD(exports, "CAMOpen", CAMOpen); } NODE_MODULE(FaceRecognition, init)

建立编译文件binding.gyp

{ "targets": [ { "target_name": "FaceRecognition", "sources": [ "FaceRecognition.cpp" ] } ] }

安装编译环境

npm install -g node-gyp

安装python

conda create -name python27 python=2.7

activate python27

编译器

本人的编译环境是vs2015

编译模块

node-gyp configure build

创建测试文件test.js

const FaceRecognition = require('./build/Release/FaceRecognition'); console.log(FaceRecognition.CAMOpen()); 测试

开发NodeJS扩展模块也可以使用Native Abstractions for Node.js
