PHP 库，用于从任何网页中检索服务器信息，如安装的 CMS、Web 服务器、DNS 查询等...

要求

• PHP 5.4+
• 已安装 Curl 库
• allow_url_fopen: 开启

安装库

安装此库的首选方式是使用Composer。

$ php composer.phar require zeichen32/website-info ~1.0

用法

// Create a new WebsiteInfo instance with all default parser
$ws = \WebsiteInfo\Factory::createWithDefaultParser();

// OR
$ws = \WebsiteInfo\Factory::create(array(
            new \WebsiteInfo\Parser\Webserver\Apache(),
            new \WebsiteInfo\Parser\Webserver\Nginx(),
            new \WebsiteInfo\Parser\Webserver\IIS(),
            // ...
    ));

// Retrieve informations about wordpress.com
$result = $ws->get('http://wordpress.com');

print_r($result);

可用的解析器

创建自己的解析器

1. 创建一个新解析器，用于对响应进行某些操作

namespace Acme\Parser;

use WebsiteInfo\Event\ParseResponseEvent;
use WebsiteInfo\Parser\AbstractParser;

class MyParser extends AbstractParser {

    public function onParseResponse(ParseResponseEvent $event)
    {
        // Get response object
        $response = $event->getResponse();
        
        // Do something with the response
        $something = $this->doSomething( (string) $response->getBody() );

        // Add a new section to the output container
        $event->getData()->addSection('my_new_section', array(
            'foo' => 'bar',
            'version' => '1.0',
            'score' => 1,
            'raw' => $something
        ));
    }
}

1. 使用您的解析器

// Create a new WebsiteInfo instance
$ws = \WebsiteInfo\Factory::createWithDefaultParser();

// Register your parser
$ws->addParser(new \Acme\Parser\MyParser());

// Retrieve informations about wordpress.com
$result = $ws->get('http://wordpress.com');

使用结果容器缓存

1. 使用 ArrayCache（内存缓存）

// Create a new WebsiteInfo instance
$ws = \WebsiteInfo\Factory::createWithDefaultParser();

// Using the array cache
$ws->setCache(new \TwoDevs\Cache\ArrayCache());

// Retrieve informations about wordpress.com
$result = $ws->get('http://wordpress.com');

1. 如果已安装 doctrine 缓存，可以使用 doctrine 缓存适配器来缓存结果容器。

// Create a new WebsiteInfo instance
$ws = \WebsiteInfo\Factory::createWithDefaultParser();

// Create a new DoctrineCache instance
$doctrineCache = new \Doctrine\Common\Cache\FilesystemCache('var/cache');

// Create a new DoctrineCache adapter
$cacheAdapter = new \TwoDevs\Cache\DoctrineCache($doctrineCache);

// Using the cache
$ws->setCache($cacheAdapter);

// Retrieve informations about wordpress.com
$result = $ws->get('http://wordpress.com');

1. 如果已安装 zend 缓存，可以使用 zend 缓存适配器来缓存结果容器。

// Create a new WebsiteInfo instance
$ws = \WebsiteInfo\Factory::createWithDefaultParser();

// Create a new ZendStorage instance
$zendCache = new \Zend\Cache\Storage\Adapter\Memory();

// Create a new ZendCache adapter
$cacheAdapter = new \TwoDevs\Cache\ZendCache($zendCache);

// Using the cache
$ws->setCache($cacheAdapter);

// Retrieve informations about wordpress.com
$result = $ws->get('http://wordpress.com');

如何使用不同的 HttpClient

此库使用Saxulum HttpClientInterface，允许您简单地更改所使用的 HttpClient。

例如，您想使用Buzz作为 HttpClient

1. 将 Buzz 适配器添加到您的 composer.json

$ php composer.phar require saxulum-http-client-adapter-buzz ~1.0

1. 创建新的 BuzzClient

    // Create a new Buzz Client 
    $buzz = new \Buzz\Browser();
    
    // Create the client adapter
    $client = new \Saxulum\HttpClient\Buzz\HttpClient($guzzle);
    
    // Create a new WebsiteInfo instance with all default parser and custom client
    $ws = \WebsiteInfo\Factory::createWithDefaultParser($client);
    
    // Retrieve informations about wordpress.com
    $result = $ws->get('http://wordpress.com');
    
    print_r($result);
