登錄后使用cURL捕獲來自網站的數據？

Question

我要嘗試的是登錄網站，然后從表中獲取數據，因為它們沒有導出功能。 到目前為止，我已經成功登錄，它向我顯示了用戶主頁。 但是，我需要導航到其他頁面，或者以某種方式獲取該頁面，同時仍然使用curl登錄。

到目前為止，我的代碼：

$username="email"; 
$password="password"; 
$url="https://jiltapp.com/sessions"; 
$cookie="cookie.txt";
$url2 = "https://jiltapp.com/shops/shopname/orders";

$postdata = "email=".$username."&password=".$password; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result;  
curl_close($ch);

正如我提到的，我可以訪問主用戶頁面，但是我需要獲取$ url2變量的內容，而不是$ url。 我該怎么做？

謝謝！

登錄后，再次請求包含您要查找的數據的頁面。

對於后續的錄入，必須設置選項CURLOPT_COOKIEFILE ，該選項指向與CURLOPT_COOKIEJAR相同的文件。 cURL將從該文件中讀取Cookie並將其與請求一起發送。

$username="email"; 
$password="password"; 
$url="https://jiltapp.com/sessions"; 
$cookie="cookie.txt";
$url2 = "https://jiltapp.com/shops/shopname/orders";

$postdata = "email=".$username."&password=".$password; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie);  // <-- add this line
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result;  

// make second request

$url = 'page you want to get data from';
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 0);

$data = curl_exec($ch);
