node插件

1. 安装环境

npm install -g node-gyp

2. 配置

node-gyp configure

3. 生成插件

执行node-gyp build命令后，在build/Release/目录下会生成faker.node文件

4. 测试代码

node test.js

const faker = require('./faker.node');

// 查看当前node的v8版本
console.log(faker.v8_version);

// 自定义的打印函数
faker.print("1111");

// 自定义绑定数据到底层，规避检测
o = {}
faker.set_data(o, 'cache', { 'name': 'val' });
console.log('cache: ', faker.get_data(o, 'cache'));
console.log("js层无法感知到cache的存在: ", o)
faker.del_data(o, 'cache');
console.log('cache: ', faker.get_data(o, 'cache'));

// 自定义的执行js函数()
faker.run_js("console.log('faker.run_js is called')", "VM1");
faker.run_js(`
    try{
        throw new Error("test");
    }catch(e){
        console.log(e.stack);
    }
    `, "https://www.test.com/test.js");

// 自定义的执行js文件函数
faker.run_js_file("./temp.js", "VM2");
// faker.run_js_file("./temp.js", "https://www.test.com/temp.js");


// 封装native函数
test = faker.native({
    name: "test",
    length: 0,
    cb: function () {
        console.log("native test is called:", ...arguments);
    }
});
console.log("test.toString():  ", test.toString());
test("hi faker.native");

// 生成HTMLAllCollection原型及document.all对象
document = {}

    console.log("document.all is called:", ...arguments);
    let cache = faker.get_data(document.all, "cache")

// 设置document.all的数据
