加载异步数据后获取网页源

Question

I am trying to retrieve the page source of a page on another domain after it has loaded the content it gathers asynchronously.

I have tried PHP's file_get_contents, but this does not obtain the source code after the asynchronous data is loaded.

Any help is appreciated.

There is no way you can do that using PHP's file_get_contents or even using cURL. You have to look into other options.

Like, PHP's V8js module: http://php.net/manual/en/book.v8js.php

or you can try to use Selenium.

What you are looking for is basically a way to execute the JavaScript from with in php.

Ofcourse you could always peep into the asynchronous requests on the page, and make your own requests too!
