Documentation

Request handler that converts controller method return values to PSR-7 responses

This handler wraps a controller method callable and automatically converts its return value to a ResponseInterface using the converter registry.

Conversion flow:

  1. Invoke the controller method with URL parameters from request attributes
  2. If return value is already ResponseInterface, return it directly
  3. Otherwise, use converter registry to convert return value to ResponseInterface
  4. If no converter found, throw RuntimeException

This enables controllers to return any type (arrays, strings, domain objects) without manually creating Response objects.

Example:

// Controller method returns array
public function index(): array {
    return ['users' => $this->users];
}

// ConverterHandler converts array → ResponseInterface via registered converter
$handler = new ConverterHandler($this->index(...));
$response = $handler->handle($request); // JSON response
