用Goutte/Guzzle登录后下载文件

Question

我想登录该网页并下载文件。

到目前为止，我尝试了下面的代码。问题是，看来我没有被授权了。下载的文件是login.html页面。

有人知道如何使这项工作？提前致谢！

<?php 

require 'vendor/autoload.php'; 

use Goutte\Client; 

$client = new Client(); 

$crawler = $client->request('GET', 'https://website.com/login.php'); 

$form = $crawler->selectButton('Login')->form(); 
$crawler = $client->submit($form, array('username' => 'username', 'password' => 'password')); 

... 

$download_link = 'https://website.com/extracted_download_link_from_crawler.pdf'; 

$guzzleClient = $client->getClient(); 

$response = $guzzleClient->get($download_link, ['save_to' => '/local_path/file.pdf']); 

Answer 1

想通了自己：

我从GOUTTE客户端的cookie和它们存储在狂饮客户cookiejar：

//get the PHPSESSION COOKIE 
$cookieJar = $goutteClient->getCookieJar(); 
$all_cookies = $cookieJar->all(); 
$PHPSESSID_value = $all_cookies[7]->getValue(); 

//Update the cookie for different guzzleClient and download 
$guzzleClient = $client->getClient(); 
$jar = new \GuzzleHttp\Cookie\CookieJar; 
$response = $guzzleClient->get($download_link, ['cookies' => $jar, 'save_to' => '/local_path/file.pdf']); 

Answer 2

$cookieJar = $client->getCookieJar(); 
$guzzleClient = $client->getClient(); 
$jar = GuzzleHttp\Cookie\CookieJar::fromArray($cookieJar->all(), 'website.com'); 
$response = $guzzleClient->get('URL TO FILE', ['cookies' => $jar, 'sink' => 'my.pdf']);
