Introduction

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...).

Installation

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(),
            // ...
        );
    }
}

Usage

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.

Testing

$ docker run --rm -v `pwd`:/app phpunit/phpunit -c /app
