Execute browser page/javascript from a script/command-line

Hope this isnt a stupid question.
I have recently had an idea about something which I am very curious about.
I am a fan of Node.js (not really relevent here I think) and the V8 engine but I was wondering if its possible to run a browser (get it to execute JS) but INTERNALLY.

What I mean by that is to create a program (possibly using the V8 engine) which can open a page (as if in the browser) and execute its javascript.

For instance say I have the below file hosted on www.mysite.co.uk/home.php

<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
//javascript AJAX call to www.mysite.co.uk/ping.php
}
myFunction();
</script>
</head>

<body>
</body>
</html>

And ping.php looks something like:

<?php
//connect mysql, database ping and table ping
//it is a single column table with integer value starting on 0
//increment by 1 and update the table

Say I wanted to get the Javascript to execute by using some sort of script on my command line/linux box (essentially WITHOUT using a browser).

So something like:

./mybrowser http://www.mysite.co.uk/home.php

or even:

./mybrowser home.php

I feel like it should be possible as the V8 (or different JS engine) should technically be able to execute Javascript but I havnt the foggiest how it could do so out of a browser context (or even if its possible).

Any ideas?

有帮助吗？

解决方案

You can use any js engine to run js scripts as long as they do not rely on the DOM.

You could start by looking at:

Edit: as I understand you want a headless browser, here are some:

  • HTMLUnit (I use that one for unit testing)
  • PhantomJS
  • Zombie.js

其他提示

Running JavaScript on the command line by using either Rhino for Java or Windows Script Host.
