Library for scraping free proxies lists written in PHP
composer require vantoozz/proxy-scraper:~2 php-http/guzzle6-adapter hanneskod/classtools<?php declare(strict_types = 1);
use function Vantoozz\ProxyScraper\proxyScraper;
require_once __DIR__ . '/vendor/autoload.php';
foreach (proxyScraper()->get() as $proxy) {
echo $proxy . "\n";
}This is version 2 of the library. For version 1 please check v1 branch.
The library requires a PSR-18 compatible HTTP client. To use the library you have to install any of them, e.g.:
composer require php-http/guzzle6-adapterAll available clients are listed on Packagist: https://packagist.org/providers/psr/http-client-implementation.
Then install proxy-scraper library itself:
composer require vantoozz/proxy-scraper:~2The simplest way to start using the library is to use proxyScraper() function
which instantiates and configures all the scrapers.
Please note, auto-configuration function in addition to php-http/guzzle6-adapter
requires hanneskod/classtools dependency.
composer require php-http/guzzle6-adapter hanneskod/classtools<?php declare(strict_types = 1);
use function Vantoozz\ProxyScraper\proxyScraper;
require_once __DIR__ . '/vendor/autoload.php';
foreach (proxyScraper()->get() as $proxy) {
echo $proxy . "\n";
}You can override default parameters of the HTTP client like this:
<?php declare(strict_types=1);
use GuzzleHttp\Client as GuzzleClient;
use Http\Adapter\Guzzle6\Client as HttpAdapter;
use Http\Message\MessageFactory\GuzzleMessageFactory as MessageFactory;
use Vantoozz\ProxyScraper\HttpClient\Psr18HttpClient;
use function Vantoozz\ProxyScraper\proxyScraper;
require_once __DIR__ . '/vendor/autoload.php';
$httpClient = new Psr18HttpClient(
new HttpAdapter(new GuzzleClient([
'connect_timeout' => 2,
'timeout' => 3,
])),
new MessageFactory
);
foreach (proxyScraper($httpClient)->get() as $proxy) {
echo $proxy . "\n";
}Of course, you may manually configure the scraper and underlying HTTP client:
<?php declare(strict_types = 1);
use GuzzleHttp\Client as GuzzleClient;
use Http\Adapter\Guzzle6\Client as HttpAdapter;
use Http\Message\MessageFactory\GuzzleMessageFactory as MessageFactory;
use Vantoozz\ProxyScraper\HttpClient\Psr18HttpClient;
use Vantoozz\ProxyScraper\Scrapers;
require_once __DIR__ . '/vendor/autoload.php';
$httpClient = new Psr18HttpClient(
new HttpAdapter(new GuzzleClient([
'connect_timeout' => 2,
'timeout' => 3,
])),
new MessageFactory
);
$scraper = new Scrapers\FreeProxyListScraper($httpClient);
foreach ($scraper->get() as $proxy) {
echo $proxy . "\n";
}You can easily get data from many scrapers at once:
<?php declare(strict_types = 1);
use GuzzleHttp\Client as GuzzleClient;
use Http\Adapter\Guzzle6\Client as HttpAdapter;
use Http\Message\MessageFactory\GuzzleMessageFactory as MessageFactory;
use Vantoozz\ProxyScraper\HttpClient\Psr18HttpClient;
use Vantoozz\ProxyScraper\Scrapers;
require_once __DIR__ . '/vendor/autoload.php';
$httpClient = new Psr18HttpClient(
new HttpAdapter(new GuzzleClient([
'connect_timeout' => 2,
'timeout' => 3,
])),
new MessageFactory
);
$compositeScraper = new Scrapers\CompositeScraper;
$compositeScraper->addScraper(new Scrapers\FreeProxyListScraper($httpClient));
$compositeScraper->addScraper(new Scrapers\CoolProxyScraper($httpClient));
$compositeScraper->addScraper(new Scrapers\SocksProxyScraper($httpClient));
foreach ($compositeScraper->get() as $proxy) {
echo $proxy . "\n";
}Sometimes things go wrong. This example shows how to handle errors while getting data from many scrapers:
<?php declare(strict_types = 1);
use Vantoozz\ProxyScraper\Exceptions\ScraperException;
use Vantoozz\ProxyScraper\Ipv4;
use Vantoozz\ProxyScraper\Port;
use Vantoozz\ProxyScraper\Proxy;
use Vantoozz\ProxyScraper\Scrapers;
require_once __DIR__ . '/vendor/autoload.php';
$compositeScraper = new Scrapers\CompositeScraper;
// Set exception handler
$compositeScraper->handleScraperExceptionWith(function (ScraperException $e) {
echo 'An error occurs: ' . $e->getMessage() . "\n";
});
// Fake scraper throwing an exception
$compositeScraper->addScraper(new class implements Scrapers\ScraperInterface
{
public function get(): \Generator
{
throw new ScraperException('some error');
}
});
// Fake scraper with no exceptions
$compositeScraper->addScraper(new class implements Scrapers\ScraperInterface
{
public function get(): \Generator
{
yield new Proxy(new Ipv4('192.168.0.1'), new Port(8888));
}
});
//Run composite scraper
foreach ($compositeScraper->get() as $proxy) {
echo $proxy . "\n";
}Will output
An error occurs: some error
192.168.0.1:8888
In the same manner you may configure exceptions handling for the scraper
created with proxyScraper() function as it returns an instance of CompositeScraper:
<?php declare(strict_types = 1);
use Vantoozz\ProxyScraper\Exceptions\ScraperException;
use function Vantoozz\ProxyScraper\proxyScraper;
require_once __DIR__ . '/vendor/autoload.php';
$scraper = proxyScraper();
$scraper->handleScraperExceptionWith(function (ScraperException $e) {
echo 'An error occurs: ' . $e->getMessage() . "\n";
});Validation steps may be added:
<?php declare(strict_types = 1);
use Vantoozz\ProxyScraper\Exceptions\ValidationException;
use Vantoozz\ProxyScraper\Ipv4;
use Vantoozz\ProxyScraper\Port;
use Vantoozz\ProxyScraper\Proxy;
use Vantoozz\ProxyScraper\Scrapers;
use Vantoozz\ProxyScraper\Validators;
require_once __DIR__ . '/vendor/autoload.php';
$scraper = new class implements Scrapers\ScraperInterface
{
public function get(): \Generator
{
yield new Proxy(new Ipv4('104.202.117.106'), new Port(1234));
yield new Proxy(new Ipv4('192.168.0.1'), new Port(8888));
}
};
$validator = new Validators\ValidatorPipeline;
$validator->addStep(new Validators\Ipv4RangeValidator);
foreach ($scraper->get() as $proxy) {
try {
$validator->validate($proxy);
echo '[OK] ' . $proxy . "\n";
} catch (ValidationException $e) {
echo '[Error] ' . $e->getMessage() . ': ' . $proxy . "\n";
}
}Will output
[OK] 104.202.117.106:1234
[Error] IPv4 is in private range: 192.168.0.1:8888
A Proxy object may have metrics (metadata) associated with.
By default Proxy object has source metric:
<?php declare(strict_types = 1);
use GuzzleHttp\Client as GuzzleClient;
use Http\Adapter\Guzzle6\Client as HttpAdapter;
use Http\Message\MessageFactory\GuzzleMessageFactory as MessageFactory;
use Vantoozz\ProxyScraper\HttpClient\Psr18HttpClient;
use Vantoozz\ProxyScraper\Proxy;
use Vantoozz\ProxyScraper\Scrapers;
require_once __DIR__ . '/vendor/autoload.php';
$httpClient = new Psr18HttpClient(
new HttpAdapter(new GuzzleClient([
'connect_timeout' => 2,
'timeout' => 3,
])),
new MessageFactory
);
$scraper = new Scrapers\FreeProxyListScraper($httpClient);
/** @var Proxy $proxy */
$proxy = $scraper->get()->current();
foreach ($proxy->getMetrics() as $metric) {
echo $metric->getName() . ': ' . $metric->getValue() . "\n";
}Will output
source: Vantoozz\ProxyScraper\Scrapers\FreeProxyListScraper
Note. Examples use Guzzle as HTTP client.
./vendor/bin/phpunit --testsuite=unit./vendor/bin/phpunit --testsuite=integrationphp ./tests/systemTests.phpThe biggest difference from version 1 is using a PSR-18 instead of HTTPlug compatible HTTP client.
Instead of
$httpClient = new \Vantoozz\ProxyScraper\HttpClient\GuzzleHttpClient(
new \GuzzleHttp\Client([
'connect_timeout' => 2,
'timeout' => 3,
])
);the client should be instantiated like
$httpClient = new \Vantoozz\ProxyScraper\HttpClient\Psr18HttpClient(
new \Http\Adapter\Guzzle6\Client(new \GuzzleHttp\Client([
'connect_timeout' => 2,
'timeout' => 3,
])),
new \Http\Message\MessageFactory\GuzzleMessageFactory
);
