Tiki17 and Tiki16, but will likely work on previous versions. This is for advanced users for now. In the future, it will be easier to install, and it will be possible to write recipes in wiki pages. See Browser Automation.
CasperJS is a navigation scripting & testing utility for PhantomJS and SlimerJS (still experimental). It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks such as:
defining & ordering navigation steps
capturing screenshots of a page (or an area)
making assertions on remote DOM
logging & events
downloading resources, even binary ones
catching errors and react accordingly
writing functional test suites, exporting results as JUnit XML (xUnit)
PhantomJS is an optimal solution for fast headless testing, site scraping, pages capture, SVG renderer, network monitoring and many other use cases.
Add, in the composer.json, the following lines to “post-install-cmd” and “post-update-cmd” of the “scripts” section:
Install composer (if missing) and the following PHP packages (by running these commands on the command line):
sudo apt-get install composer # or adapt to your distro/OS: "yum install composer", etc composer require --prefer-dist "jerome-breton/casperjs-installer:dev-master" composer require --prefer-dist "phpcasperjs/phpcasperjs"
sh setup.shin the tiki root folder, as usual, to run the installers of phantomjs and casperjs, and remove the unneeded dev packages added by composer.
Use the following script to test (in the root of tiki, adjust path if other folder):
Create a file (ex.: scrape.php) with the following content
<?php // Require composer autoload require_once __DIR__ . '/vendor/autoload.php'; use Browser\Casper; $casper = new Casper(__DIR__ . '/bin/'); $casper->setOptions(array( 'ignore-ssl-errors' => 'yes' )); // screen shoot of homepage $casper ->start('http://tiki.org') ->setViewPort(1024,800) ->waitForText('About Tiki') ->wait(200) ->capture( array( 'top' => 0, 'left' => 0, 'width' => 1024, 'height' => 800 ), 'custom-capture.png' ) ->run(); echo "The image was captured <br> <br> <img alt='' border='0' src='custom-capture.png'>";
Once you visit the newly created file, it will fetch the info at http://tiki.org and generate custom-capture.png
/usr/binfolder where all programs are located on symlinked.
Imagine that your root tiki folder is
/var/www/html/. Then you can create a symbolic link for each of the programs:
ln -s /var/www/html/bin/casperjs /usr/bin/casperjs ln -s /var/www/html/bin/phantomjs /usr/bin/phantomjs
This way you will be able to call casperjs or phantomjs from anywere in the server, if you need it for your other custom scripts doing scraping for you sever-side.
