}本質就是用的 response 類
public function __construct($content = '', $status = 200, $headers = array())
if (isset(self::$deprecationstriggered[$class]))
self::$deprecationstriggered[$class] = true;
foreach (self::$deprecatedmethods as $method)
}}public function setcontent($content)

return $this;
}public function setstatuscode($code, $text = null)
if (null === $text)

$this->statustext = $text;
return $this;
}public function isinvalid()
public function setprotocolversion($version)
主要是設定響應頭
public function prepare(request $request)
else
}// 設定編碼格式
$charset = $this->charset ?: 'utf-8';
if (!$headers->has('content-type')) elseif (0 === stripos($headers->get('content-type'), 'text/') && false === stripos($headers->get('content-type'), 'charset'))
// 若傳輸時用分塊編碼,則移除 content-length, 因為採用分塊編碼時可以知道傳輸何時完成
