从远程页面获取JavaScript变量？

Question

I am currently working on developing an API for a company. Specifically, here's my issue. They have JavaScript arrays on a webpage that their webmaster updates. I have to pull these arrays into either a simple JS script or PHP file and get the contents of these arrays, which I can then arrange according to the API's specifications and output it as JSON.

How do I pull a JavaScript variable in from a remote page in either PHP or jQuery/JS and make it usable for other applications?

No, I don't have access to the company's website. I have to work off of page scraping for this one.

Thank you!

Answer 1

You can't access private javascript variables remotely, due to Same origin policy . They would have to output the arrays in some kind of readable format that you could access using AJAX, probably as JSON.

Edit: As mentioned below, if the array is explicitly defined as text in a javascript file, you could grab the contents of that file using cURL in PHP

如果我在哪里，我将使用PHP来file_get_contents （或CURL具体取决于服务器配置）页面，然后根据任何标记对其进行解析，以找到变量的值，并假设变量已写到页面中。第一名。
