A Symfony bundle for the Crawler-Detect library (detects bots/crawlers/spiders via the user agent).
This Bundle integrates the Crawler-Detect library into Symfony. It is recommended to read the lib's documentation before continuing here.
The aim of this bundle is to expose the CrawlerDetect
class as a service (crawler_detect) to make it easier to use with Symfony
(dependency injection, usable from a controller, etc...).
Download the bundle using composer :
$ composer require nmure/crawler-detect-bundle "^2.0.0"For Symfony < 4.0, run :
$ composer require nmure/crawler-detect-bundle "^1.0.0"then enable the bundle in your AppKernel :
// app/AppKernel.php
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array(
// ...
new Nmure\CrawlerDetectBundle\CrawlerDetectBundle(),
// ...
);
}
}The crawler_detect service is initialized with the data from
the Symfony's master request.
To use this service from a controller :
public function indexAction()
{
if ($this->get('crawler_detect')->isCrawler()) {
// this request is from a crawler :)
}
// you can also specify an user agent if you don't want
// to use the one of the master request or if the app
// is accessed by the CLI :
$ua = 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)';
if ($this->get('crawler_detect')->isCrawler($ua)) {
// this user agent belongs to a crawler :)
}
}You can also inject this service as a dependency
using the crawler_detect service id.
$ docker run --rm -v `pwd`:/app phpunit/phpunit -c /app
