Crawler html is empty when retrieved from a function or class method #418
Description
I ran into what I consider a 'bizarre' issue the other day:
When a Symfony\Component\Panther\Client instance is used within the same calling function/method and the Symfony\Component\Panther\DomCrawler\Crawler instance is retrieved, everything works.
However, if the Crawler is retrieved from another function/method, Crawler::html() provides an empty string.
Example class:
<?php
namespace App\Test;
use Symfony\Component\Panther\Client;
use Symfony\Component\Panther\DomCrawler\Crawler;
class PantherTest
{
/**
* @var string
*/
protected $url;
public function __construct()
{
$this->url = 'https://example.com/';
}
/**
* @return Crawler
*/
protected function fetchUrlGetCrawler(): Crawler
{
$client = Client::createChromeClient();
$client->request( 'GET', $this->url );
return $client->getCrawler();
}
public function test1()
{
$client = Client::createChromeClient();
$client->request( 'GET', $this->url );
$crawler = $client->getCrawler();
dump( $crawler->html() );
}
public function test2()
{
$crawler = $this->fetchUrlGetCrawler();
dump( $crawler->html() );
}
}The PantherTest::test1 method works as expected:
$test = new PantherTest();
$test->test1();but the PantherTest::test2 method does not, even though the exact same code is duplicated inside another method:
$test = new PantherTest();
$test->test2();I've tried this on both my local dev server, and a remote debian/apache server with the same results.
