pine3ree invokable request handler
This package provides a psr server-request handler that can be invoked directly.
Descendant classes or classes using the InvokableRequestHandlerTrait
must implement
the __invoke
method, whose dependencies are resolved either using the request
attributes or by the container, via the composed params-resolver. A type-hinted
ServerRequestInterface
dependency is resolved to the current request.
The default implementation requires the return type to be a psr-response object.
In scenarios where you might need to return other types, you will also need to
override the default psr handle
method and build a response object using the
return value of the protected method invokeHandler(ServerRequestInterface)
which is responsible for executing the handler itself after resolving its
arguments.
How it works
$handler->handle($request)
calls protected method $this->invokeHandler($request)
$this->invokeHandler($request)
resolve __invoke
$args
and calls $this(...$args)
