curl获取内容以及模拟登录问题

<?phpecho $cookie_file= tempnam('./tmp','cookie');
$curl_login="http://xiaoxin.duapp.com/wp-login.php";
$curl_logined="http://xiaoxin.duapp.com/index.php";
$user = "##";
$pass = "##";
$curlPost = "log=$user&pwd=$pass";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $curl_login);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
$data = curl_exec($ch);
curl_close($ch);$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $curl_logined);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLCOOKIEFILE, $cookie_file);$data = curl_exec($ch);
curl_close($ch);?>
设置$curl_logined="http://xiaoxin.duapp.com/index.php";时无法显示
设置$curl_logined="http://xiaoxin.duapp.com/";可以正常读取
但是没能登录
