Phantomjs相当于浏览器的“页面另存为...，完整的网页"； [英] Phantomjs equivalent of browser's "Save Page As... Webpage, complete"

问题描述

对于我的应用程序，我需要以编程方式保存网页HTML的副本以及呈现它所需的图像和资源.浏览器的Save page as... Webpage, complete选项具有此功能.

For my application I need to programmatically save a copy of a webpage HTML along with the images and resources needed to render it. Browsers have this functionality in their Save page as... Webpage, complete options.

使用phantomjs或casperjs保存页面的呈现HTML当然很容易.但是，我还没有看到将其与下载关联的图像相结合，并进行必要的DOM更改以使用下载的图像的任何示例.

It is of course easy to save the rendered HTML of a page using phantomjs or casperjs. However, I have not seen any examples of combining this with downloading the associated images, and doing the needed DOM changes to use the downloaded images.

鉴于此功能存在于基于Webkit的浏览器(Chrome，Safari)中，我很惊讶它不在phantomjs中-也许我只是没有找到它！

Given that this functionality exists in webkit-based browsers (Chrome, Safari) I'm surprised it isn't in phantomjs -- or perhaps I just haven't found it!

推荐答案

或者使用PhantomJS，您可以使用CasperJS来获得所需的结果. CasperJS是基于PhantomJS的框架，但是具有支持和补充PhantomJS的各种模块和类.

Alternatively the PhantomJS, you can use the CasperJS to achieve the required result. CasperJS is a framework based on the PhantomJS, however, with a variety of modules and classes that support and complement the PhantomJS.

您可以使用的脚本示例是:

An example of a script that you can use is:

casper.test.begin('test script', 0, function(test) {
    casper.start(url);

    casper.then(function myFunction(){
        //...
    });

    casper.run(function () {
        //...
        test.done();
    });
});

使用此脚本，您可以在一个步骤"中执行下载，无论是文档，页面，印刷品还是其他任何图像. 研究download 方法， getPageContent 和 capture / captureSelector /casperjs.readthedocs.org/en/latest/modules/casper.html"rel =" nofollow>此链接.

With this script, within a "step", you can perform your downloads, be it a single image of a document, the page, a print or whatever. Take a study on the download methods, getPageContent and capture / captureSelector in this link.
