在 CakePHP 中使用自定义状态代码 2.x

Question

我需要为 CakePHP 2.x 中的响应使用自定义状态代码，例如 422。

然而 CakeResponse class only allows those status codes that are already setup in the CakeResponse class.

有没有办法让我在 CakePHP 中使用我的自定义状态代码？

注意如果答案是使用自定义 CakeResponse class there is a related question regarding that.

您查找 API 很酷，但请继续阅读：

Queries & sets valid HTTP response codes & messages.

/**
 * Queries & sets valid HTTP response codes & messages.
 *
 * @param int|array $code If $code is an integer, then the corresponding code/message is
 *        returned if it exists, null if it does not exist. If $code is an array, then the
 *        keys are used as codes and the values as messages to add to the default HTTP
 *        codes. The codes must be integers greater than 99 and less than 1000. Keep in
 *        mind that the HTTP specification outlines that status codes begin with a digit
 *        between 1 and 5, which defines the class of response the client is to expect.
 *        Example:
 *
 *        httpCodes(404); // returns array(404 => 'Not Found')
 *
 *        httpCodes(array(
 *            381 => 'Unicorn Moved',
 *            555 => 'Unexpected Minotaur'
 *        )); // sets these new values, and returns true
 *
 *        httpCodes(array(
 *            0 => 'Nothing Here',
 *            -1 => 'Reverse Infinity',
 *            12345 => 'Universal Password',
 *            'Hello' => 'World'
 *        )); // throws an exception due to invalid codes
 *
 *        For more on HTTP status codes see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1
 *
 * @return mixed associative array of the HTTP codes as keys, and the message
 *    strings as values, or null of the given $code does not exist.
 * @throws CakeException If an attempt is made to add an invalid status code

如果您打算将 none 标准代码与 API 一起使用，我会 return x-header 中的代码或者像 Jsend 那样的响应中的代码例如。
