使用 curl 执行 javascript 后获取源代码

get sourcecode after javascript execution with curl

提问by reox

Is it possible to get the html source code of a webpage with curl and the run a javascript interpreter over it, so i get the generated content?

是否可以使用 curl 获取网页的 html 源代码并在其上运行 javascript 解释器，以便我获得生成的内容？

The Page i need to get uses some encoded and genereated content in there so i want to first run the javascript to get the escaped and generated content... or do i need to regex the javascript and "compile" the javascript on my own? Like

我需要获取的页面在那里使用了一些编码和生成的内容，所以我想首先运行 javascript 来获取转义和生成的内容......还是我需要对 javascript 进行正则表达式并自己“编译”javascript？喜欢

curl <myurl> | perl -ne 'm/unescape\((.*)\)/; print ""' | <now to something with that>

i known there is no javascript engine in curl but can i just call another script / programm to do the job?

我知道 curl 中没有 javascript 引擎，但我可以调用另一个脚本/程序来完成这项工作吗？

You can do it, but it's more involved than I think you realize. Neither curlnor wgethave Javascript engines, so you'll need something that has one.

你可以做到，但它比我认为你意识到的更复杂。既curl没有wgetJavascript 引擎，也没有 Javascript 引擎，所以你需要有一个引擎。

I would start by looking at PhantomJS.

我会先看看PhantomJS。
