问题
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?
回答1:
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:
- Running V8 Javascript Engine Standalone
Edit: as I understand you want a headless browser, here are some:
- HTMLUnit (I use that one for unit testing)
- PhantomJS
- Zombie.js

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