Respuesta: Script PHP. ¿Es posible loguearse a otra web? Creo que doy palos de ciego. He probado estas dos funciones pero ninguna loguea, modificándola con mis datos. Evidentemente algo me falla.
Código:
<?php
/*
Here is a script that is usefull to :
- login to a POST form,
- store a session cookie,
- download a file once logged in.
*/
// INIT CURL
$ch = curl_init();
// SET URL FOR THE POST FORM LOGIN
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/Members/Login.php');
// ENABLE HTTP POST
curl_setopt ($ch, CURLOPT_POST, 1);
// SET POST PARAMETERS : FORM VALUES FOR EACH FIELD
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'fieldname1=fieldvalue1&fieldname2=fieldvalue2');
// IMITATE CLASSIC BROWSER'S BEHAVIOUR : HANDLE COOKIES
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
# Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
# not to print out the results of its query.
# Instead, it will return the results as a string return value
# from curl_exec() instead of the usual true/false.
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
// EXECUTE 1st REQUEST (FORM LOGIN)
$store = curl_exec ($ch);
// SET FILE TO DOWNLOAD
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/Members/Downloads/AnnualReport.pdf');
// EXECUTE 2nd REQUEST (FILE DOWNLOAD)
$content = curl_exec ($ch);
// CLOSE CURL
curl_close ($ch);
/*
At this point you can do do whatever you want
with the downloaded file stored in $content :
display it, save it as file, and so on.
*/
?>
Código:
<?php
// $url = page to POST data
// $ref_url = tell the server which page you came from (spoofing)
// $login = true will make a clean cookie-file.
// $proxy = proxy data
// $proxystatus = do you use a proxy ? true/false
function
curl_grab_page($url,$ref_url,$data,$login,$proxy,$proxystatus){
if($login == 'true') {
$fp = fopen("cookie.txt", "w");
fclose($fp);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'true') {
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $ref_url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
ob_start();
return curl_exec ($ch); // execute the curl command
ob_end_clean();
curl_close ($ch);
unset($ch);
}
echo curl_grab_page("https://www.example.net/login.php", "https://www.example.net/", "username=foo&password=bar", "true", "null", "false");
?>
