jsdom, proxy对象（补环境神器）以及抠代码总结的问题

jsdom

const jsdom = require('jsdom')
const {JSDOM} = jsdom
const fs = require('fs')
options = {
            url : 'http://match.yuanrenxue.com/match/2',
            referrer: 'http://match.yuansrenxue.com/match/2',
            contentType: 'text/html',
            userAgent : 'Messdfass/7800',
            includeNodeLocations: true,
            runScripts:'dangerously',
            beforeParse(location) {
                location.reload = function(){}
            },
            cookieJar:new jsdom.CookieJar(), //网站有setCookie的话，提前植入cookie
        }
        cookie = {}, url=''
options.cookieJar.setCookie(cookie, url, function () {

})
fs.readFile('./jjs.html',  'utf8', function (err, data){
    const dom = new JSDOM(data, options);
    console.log(dom.window.document.cookie)
    dom.window.close()
});

proxy

//代理普通对象
var person = {
    name: 14,
    age: 444,
    hobbies: [
        '泡妞',
        '看妹子'
    ]
}
var proxy = new Proxy(window, {
    get(target, property){
        // console.log('调用了target:', target)
        console.log('调用了property: window的', property)
        // Reflect.get(target, property)
        return target[property]
    },
    set(target, property, value){
        console.log('设置对象window', value)
        target[property] = value
    }
})
proxy.age



//代理window
window = global
window.a = '4444';
window.b = {
    name: 'xiaosheng',
    height: '200cm',
    hobbies: [
        '钓鱼',
        '养鱼'
    ]
}

var proxy = new Proxy(window, {
    get(target, property){
        // console.log('调用了target:', target)
        console.log('调用了property: window的', property)
        // Reflect.get(target, property)
        return target[property]
    },
    set(target, property, value){
        console.log('设置对象window', value)
        target[property] = value
    }
})
proxy.a = 45
// console.log(b.length)
proxy.b.length

// ->设置对象window 45
// ->调用了property: window的 b

抠代码总结 的问题

抠代码的时候，如果代码里有this，导出的话就不能直接导出了，要导出对象
