在模板引擎中呈现页面后获取页面的来源？ [英] Getting source of a page after it's rendered in a templating engine?

问题描述

所以我在一个JS很重的网站上进行一些屏幕抓取。它使用客户端模板引擎呈现所有内容。我尝试使用jQuery并且在控制台中工作，但显然不是在服务器（Nodejs）上。

So I'm doing some screen scraping on a site that is very JS heavy. It uses a client side templating engine that renders all the content. I tried using jQuery and that worked in the console, but not on the server (Nodejs), obviously.

我看了几个Python和Java库，他们似乎能够处理我想要的东西，但我更喜欢一个适用于Node的JS解决方案服务器。

I looked at a few libraries for Python and Java, and they seem to be able to handle what I want, but I would prefer a JS solution that works with a Node server.

有没有办法在使用Node渲染页面后获取完整的页面源？

Is there any way to get the complete source of a page after it's rendered, using Node?

推荐答案

我使用 jsdom 进行屏幕删除，代码就在这里。 ..

I used jsdom for screen scrapping and the code goes here...

var jsdom = require( 'jsdom' );
jsdom.env( {
url: <give_url_of_page_u_want_to_scarpe>,
scripts: [ "http://code.jquery.com/jquery.js" ],
done: function( error, window ) {
  var $ = window.$;

  // required page is loaded in $....
  //you can write any javascript or jquery code get what ever you want

}
} );
