    $cookie = 'BDORZ=B490B5EBF6F3CD402E515D22BCDA1598;';
    $cookie .= 'PSINO=2;';
    $cookie .= 'H_PS_PSSID=1461_21100_20930;';
    $cookie .= 'MCITY=-131%3A;';
    $cookie .= 'BIDUPSID=80AC6EA669AE16286E6BD37C4E7F784C;';
    $cookie .= 'PSTM=1493796031;';
    $cookie .= 'BAIDUID=127D8DCA6C31091ED3AB45E8AD4685E5:FG=1;';

    $cookie .= 'PANPSC=10135121516028446209:M3/m2/8VCaAihLW7pKbkIrHQG6qeixv0Ueq9Dt6sx0ml9A8l9xoA6xrLuQGf8Rv4MMKOMtLkW73o+m+Nb7gNpUFOHaZbYIbmD

$cookie .= 'Hm_lpvt_7a3960b6f067eb0085b7f96ff5e660b0=1505202249;';
$cookie .= 'Hm_lvt_7a3960b6f067eb0085b7f96ff5e660b0=1505202283;';
$cookie .= 'SCRC=427a5d06e18146bf705e89f4ba550546;';
$cookie .= 'STOKEN=efc2a3f0ff8377df415b8cbd7a0fd92b44c85efc96b50079e5ff3e1d1bf4cfa2;';
$cookie .= 'PANWEB=1;';

// $url = 'http://pan.baidu.com/s/1slCHt7Z';
$url = 'http://pan.baidu.com/share/init?shareid=418435232&uk=2083399743';
$ci = curl_init($url);
curl_setopt($ci, CURLOPT_COOKIE , $cookie);
curl_setopt($ci, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ci);
curl_close($ci);
echo $result;
exit;

            上面是曾经用过的curl获取百度网盘内容的代码，基本都是这个过程，主要百度做了很多防止爬取判断,需要设置很多的cookie,而且有时效限制。
