php curl抓取本地接口卡死

Question

public function query_test(){
$url='http://localhost/activityfour/pay.php/Index/query';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
// curl_setopt($ch, CURLOPT_TIMEOUT,60);
curl_setopt($ch, CURLOPT_TIMEOUT,60);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); //将数组转换为URL请求字符串
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, false);
$responds = curl_exec($ch);
echo curl_error($ch);
curl_close($ch);
$discount = json_decode($responds, true);
dump($responds);
}
接口也是在本地写的，无法成功调用接口，是要本地服务器打开允许外部访问的开关吗？
