This is the code I am using
$client = new Client();
$requests = [
$client->createRequest('GET', 'http://httpbin.org'),
$client->createRequest('GET', 'http://httpbin.org')
];
$options = [
'complete' => [
[
'fn' => function (CompleteEvent $event) {
$crawler = new Crawler('GET', $event->getRequest()->getUrl());
echo '<p>'.$crawler->filter('title')->text().'</p>';
},
'priority' => 0,
'once' => false
]
]
];
$pool = new Pool($client, $requests, $options);
$pool->wait();
It gives no error but it outputs nothing either. I have tried replacing the URLs but still I get no output.
Your primary issue with the code sample is the instantiation of your Symfony\\Component\\DomCrawler\\Crawler
object. As currently written, "GET" is the sole content of $crawler
; as a result the call to $crawler->filter()
returns an instance of Symfony\\Component\\DomCrawler\\Crawler
that contains an empty DOMNodeList. This is why your output is empty.
Replace:
$crawler = new Crawler('GET', $event->getRequest()->getUrl());
with:
$crawler = new Crawler(null, $event->getRequest()->getUrl());
$crawler->addContent(
$event->getResponse()->getBody(),
$event->getResponse()->getHeader('Content-Type')
);
