If $response is null, returns the $data directly. Supports optional initialization properties like count, limit, offset, owner, URL, status, total, position, options.

Parameters

$request : ServerRequestInterface|null

Optional PSR-7 Request object.

$response : ResponseInterface|null

Optional PSR-7 Response object.

$data : mixed = null

The main payload or data to return.

$init : array<string|int, mixed>|null = null

Optional associative array with keys:

count (int): Number of elements
limit (int): Pagination limit
offset (int): Pagination offset
params (array): Parameters for getCurrentPath()
status (int): HTTP status code
total (int): Total elements
url (string): URL to include in response
owner (array|object): Owner reference
options (array): Additional properties
position (int): Optional position in list

$accept : string|null = null

Tags

example

return $this->success(
    $request,
    $response,
    $data,
    [Output::COUNT => count($data), Output::PARAMS => $request->getQueryParams()]
);

Return values

mixed —

Returns a PSR-7 Response object with JSON if $response is provided, otherwise returns $data directly.

successWithNewBody()

Same as {@see self::success()} but guarantees a fresh response body stream before writing the envelope.


    public
                    successWithNewBody(ServerRequestInterface|null $request, ResponseInterface|null $response[, mixed $data = null ][, array<string|int, mixed>|null $init = null ][, string|null $accept = null ]) : mixed

Use this only when an upstream actor (typically a sub-controller called from the current controller method) may have already written into the shared PSR-7 body stream. Calling the plain success() in that case would concatenate two JSON envelopes — invalid JSON for any strict parser (NextJS RSC, modern fetch, etc.).

Implementation: swaps the response body for an empty stream via self::withFreshBody(), then delegates to success(). Whatever was previously written is discarded; the resulting body contains exactly one envelope.

Parameters

$request : ServerRequestInterface|null: Optional PSR-7 Request object.
$response : ResponseInterface|null: Optional PSR-7 Response object.
$data : mixed = null: The main payload or data to return.
$init : array<string|int, mixed>|null = null: Same keys as success().
$accept : string|null = null: The header accepted by the client.

Tags

example

// POST /users where dispatchAutoInvitation() writes into the shared body
public function post( ?Request $request , ?Response $response , array $args , array $init ) :mixed
{
    $result = parent::post( $request , $response , $args , $init ) ;
    $this->dispatchAutoInvitation( $request , $response , $userKey ) ;

    return $this->successWithNewBody
    (
        $request ,
        $result  ,
        $this->refetchHydratedUser( $userKey )
    ) ;
}

see

success()

Plain variant when the body has not been touched.

Return values

mixed —

Same return contract as success().

withFreshBody()

Returns the same response with a fresh, empty body stream.


    public
                    withFreshBody(ResponseInterface|null $response) : ResponseInterface|null

Use to discard whatever an upstream actor (sub-controller, middleware) may have already written, then chain into any other response helper.

Parameters

$response : ResponseInterface|null: Optional PSR-7 Response object.

Tags

example

return $this->fail( $request , $this->withFreshBody( $response ) , 502 , 'zitadel_sync_failed' ) ;

Return values

ResponseInterface|null —

The same response with a fresh empty body, or null if $response was null.
