A general purpose CasperJS PHP driver

CasperJS PHP Driver

Prerequisites

This driver will assume that the command casperjs is available in your $PATH. If not, you can install it with:

npm install -g casperjs

Installation

You can use this package in your project via composer. Add these lines to your composer.json:

"require": {
  "workdigital/casperjs-php-driver": "1.*"
},
…

Latest stable release is 1.0

Examples

Basic usage

$driver = new CasperJs\Driver();
$output = $driver->start('http://someurl.com')
                 ->run();

Setting request parameters and interacting with the page

The entire point of using a tool like Casper is to be able to properly interact with the DOM for both testing and scraping purposes. This driver tries to expose a friendly interface to do so where you can define both request params and DOM interaction before making the actual call.

$driver = new CasperJs\Driver();
$driver->start('http://someurl.com')
       ->setUserAgent('AmericanPizzaiolo')
       ->setHeaders([
           'Accept-Language' => ['en-US'],
           'Some-Header' => 'Foo-bar',
       ])
       ->evaluate('make me a pizza')
       ->setViewPort(1024, 768)
       ->waitForSelector('.selector', 30000)
       ->wait(10000)
       ->click('.selector');

$output = $driver->run();

Using a proxy for your call

$driver = new CasperJs\Driver();
$driver->start('http://someurl.com')
       ->useProxy('1.1.1.1');

$output = $driver->run();

Getting the Casper Output

Whenever you execute Driver::run() the Driver will return an Output object that will encapsulate the Casper output. Output will expose the captured casper data or throw an exception in case the desired behaviour wasn't performed (i.e. if a css selector to be present in the page after timeout expired).

Extracting Data

$html = $output->getHtml();
$statusCode = $output->getStatusCode();
$currentUrl = $output->getCurrentUrl();

casperjs-php-driver's Issues

Blank Response Laravel

Hello,

I have casperjs and phantomjs installed globally.
I run Laravel 5.2 with nginx - ubuntu 16.04
I have tried everything, even setting the path manually and installing casperjs in the public folder. All i get is a blank response.

The path to the executable is correct, because if i set it wrong i get an error.

Both phantom and casper work from the command line.

Locating casperjs binary

I have problems with exec in your file Driver.php, line 65.

this is not working both on my server and local mac

exec('casperjs ' . $filename . $this->optionBuilder->build(), $output);

But when i change it to this, it works

exec('/usr/local/bin/casperjs ' . $filename . $this->optionBuilder->build(), $output);

I think that this is because PHP doesn't know where to find casperjs executable file. Any idea how to solve this? Or at least to have this as optional configurable option, so it can be adjusted?

Thanks
