Javascript 跨噩梦ejs实例持久化cookie

我如何在多个噩梦ejs实例中持久化并传递cookie？

---

任何示例代码都会很有帮助。

下面是一个示例，说明如何使用以前会话中保存的一些cookie设置会话

// create a promise for retrieving cookies
function getCookies(url) {
  return new Promise(function (resolve) {
    Nightmare()
      .goto(url)
      .cookies.get() // get the cookies
      .end()
      .then(resolve)
  });
}

var COOKIES;
getCookies(url).then(function (cookies) {
  // save your cookies somewhere...

  // you could save them in the file system (with NodeJs) 
  require('fs').writeFileSync(
   'cookies.json',
   JSON.stringify(cookies)
  );

  // or you could set a global variable
  COOKIES = cookies;
})

// and now each time you want to use these cookies
// you would simply set them before each session
function google() {
  return new Promise(function (resolve) {
    Nightmare()
      .goto('about:blank') // create your session by going to a blank page
      .cookies.set(COOKIES) // or .cookies.set(require('fs').readFileSync('cookies.json'))
      .goto('http://google.com')
      // do your thing with the new cookies..
      .end()
      .then(resolve)
  })
}

cookie.set（COOKIES）

不起作用，因为它是一个或多个cookie，而不是一个cookie，必须循环对吗？它会起作用，因为COOKIES.set（cookiesArray）可以接受cookie对象的数组。
