PHP curl数据抓取

我有一个CURL代码从一个网站获取数据，它在过去的几个月里工作得很好，但突然停止工作，它说

HTTP/1.0 302 Moved Temporarily

$ch = curl_init();
curl_setopt($ch, CURLOPT_REFERER, $baseUrl);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
//curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIE         , $phpSId);
curl_setopt($ch, CURLOPT_COOKIEJAR      , $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE     , $cookie);
curl_setopt($ch, CURLOPT_USERAGENT      , "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:7.0.1) Gecko/20100101 Firefox/7.0.1");
curl_setopt($ch, CURLOPT_TIMEOUT        , 40);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST , 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , 0);
curl_setopt($ch, CURLOPT_URL            , $url);
curl_setopt($ch, CURLOPT_HEADER         , 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION , 1);
curl_setopt($ch, CURLOPT_POST           , 1);
curl_setopt($ch, CURLOPT_POSTFIELDS     , $data);
$result = curl_exec($ch);
curl_close ($ch);
unset($ch); 
die($result);

请帮忙，提前谢谢
