Methods

Method	Description
process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface	Appends this middleware’s class name to the ExecutionState trace.

process()

public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface

Appends this middleware’s class name to the ExecutionState trace.

Reuses the ExecutionState already on the request, or creates one and attaches it, and records static::class so a subclass traces under its own name. When the constructor enabled the header, the trace is re-read from the shared ExecutionState after the downstream handler returns, so entries appended by middleware further down the stack are included; non-scalar entries are rendered as their debug type.

Parameter	Type	Description
$request	ServerRequestInterface
$handler	RequestHandlerInterface

Returns ResponseInterface
