用cheerio执行抓取的JavaScript [英] Executing scraped JavaScript with cheerio

问题描述

我有一个网页，其中有一些JS API不会改变dom，但返回一些数字。
我想编写一个NodeJS应用程序来下载这些页面并在下载页面的上下文中执行这些功能。

I have a web page in which there are some JS APIs that don't alter the dom, but return some numbers. I'd like to write a NodeJS application that downloads such pages and executes those functions in the context of the downloaded page.

我正在看cheerio页面抓取..虽然我看到用它来导航和操作DOM是多么容易，但我没有看到任何运行页面功能的权限。是否可以这样做？

I was looking at cheerio for page scraping.. but while I see how easy is it to navigate and manipulate the DOM with it, I don't see any access to running the page functions. Is it possible to do it?

我应该看看jsdom吗？

Should I look, instead, at jsdom?

谢谢

推荐答案

听起来你想使用PhantomJS，它将提供完全渲染的输出，然后使用cheerio。

Sounds like you want to use PhantomJS, which will provide the fully rendered output, and then use cheerio on that.
