使用PHP cURL登录远程站点并导出XML

Question

我正在尝试登录IPS Light并导出XML文件。导出页面的URL是唯一的，不能在脚本中直接引用;这意味着我将需要单击主页上的必要链接，该链接将我重定向到XML导出页面。

require_once( dirname(__FILE__) . "/configuration.php" );

$username = "username";
$password = "password";

$dir = site_path."/ctemp";
$path = site_path."/ctemp/test";

$url="https://ipslight.upu.org/"; 
$postinfo = "email=".$username."&password=".$password;

$cookie_file_path = $path."/cookie.txt";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, "https://ipslight.upu.org/IPSLight.dll");
$html = curl_exec($ch);
curl_close($ch);
