PHP CURL header 设置HOST主机头进行访问并 POST提交數據

$host = array("Host: act.qzone.qq.com");// 域名不帶http://
$data = array(
            ‘aa‘ => ‘xx‘,
            ‘bb‘=>‘xx‘
        );     
$url = ‘http://127.0.0.1/xxx/xxx/api/‘;
var_dump( $this->curl_post($host, $data,$url) );

function curl_post($host,$data,$url)
{
   $ch = curl_init();
   $res= curl_setopt ($ch, CURLOPT_URL,$url);
   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
   curl_setopt ($ch, CURLOPT_HEADER, 0);
   curl_setopt($ch, CURLOPT_POST, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
   curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch,CURLOPT_HTTPHEADER,$host);
   $handles = curl_exec($ch);
   curl_close($ch);
   return $handles;
}
function postData($url, $post)
