NightmareJS屏幕截图回调 [英] NightmareJS screenshot callback

问题描述

我正在使用此框架制作几个URL的屏幕截图.截屏的过程是异步的，并且该方法没有提供执行回调的方法，并且我想在此脚本上制作每个截屏时执行回调:

I'm using this framework to make screenshots of several urls. The process of taking the screenshot is async, and the method does not provide a way to execute a callback, and I want to execute a callback when each screenshot is made on this script:

nightmare = new Nightmare();
urls.forEach(function (url) {
    nightmare.goto(url).screenshot(path);
});

nightmare.run(function () {
  console.log('finished all');
});

有什么主意我该怎么做?

Any ideas how can I do this?

推荐答案

我找到了一种使用"use"方法执行插件的方法.

I found a way to do this, with the "use" method for executing plugins.

nightmare = new Nightmare();
urls.forEach(function (url) {
    nightmare.goto(url).screenshot(path).use(function () {
        console.log('finished one');
    });
});

nightmare.run(function () {
    console.log('finished all');
});
