PHP 인터페이스 Phly\Conduit\MiddlewareInterface
Middleware accepts a request and a response, and optionally a
callback
$out (called if the middleware wants to allow further
middleware to process the incoming request, or to delegate output to another
process).
Middleware that does not need or desire further processing should not
call
$out, and should usually instead
return $response->end();.
For the purposes of Conduit,
$out is typically one of either an instance
of
Next or an instance of
FinalHandler, and, as such, should follow
those calling semantics.

Process an incoming request and/or response. |

메소드 상세
Accepts a server-side request and a response instance, and does
something with them.
If the response is not complete and/or further processing would not
interfere with the work done in the middleware, or if the middleware
wants to delegate to another process, it can use the $out callable
if present.
If the middleware does not return a value, execution of the current
request is considered complete, and the response instance provided will
be considered the response to return.
Alternately, the middleware may return a response instance.
Often, middleware will return $out();, with the assumption that a
later middleware will return a response.
