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();
