GouttePHP 爬虫库
Goutte 是一个抓取网站数据的 PHP 库。它提供了一个优雅的 API,这使得从远程页面上选择特定元素变得简单。
示例代码:
require_once '/path/to/goutte.phar'; use Goutte\Client; //发送请求 $client = new Client(); $crawler = $client->request('GET', 'http://www.oschina.net/'); //点击链接 $link = $crawler->selectLink('Plugins')->link(); $crawler = $client->click($link); //提交表单 $form = $crawler->selectButton('sign in')->form(); $crawler = $client->submit($form, array('signin[username]' => 'fabien', 'signin[password]' => 'xxxxxx')); //提取数据 $nodes = $crawler->filter('.error_list'); if ($nodes->count()) { die(sprintf("Authentication error: %s\n", $nodes->text())); } printf("Nb tasks: %d\n", $crawler->filter('#nb_tasks')->text());
