In diesem Fall wird der Funktionsparameter `q` optional, und standardmäßig `None` sein.

!!! check
    Beachten Sie auch, dass **FastAPI** intelligent genug ist, um zu erkennen, dass `item_id` ein Pfad-Parameter ist und `q` keiner, daher muss letzteres ein Query-Parameter sein.

## Query-Parameter Typkonvertierung

Sie können auch `bool`-Typen deklarieren und sie werden konvertiert:

		// Upstream will block when request channel is full.
		// Response packets can be sent at any time.
		// Any non-nil error sent as response means no more responses are sent.
		Handle StreamHandlerFn

		// Subroute for handler.
		// Subroute must be static and clients should specify a matching subroute.
		// Should not be set unless there are different handlers for the same HandlerID.
		Subroute string

## Über Sicherheit, APIs und Dokumentation

Das Verstecken Ihrer Dokumentationsoberflächen in der Produktion *sollte nicht* die Methode sein, Ihre API zu schützen.

Dadurch wird Ihrer API keine zusätzliche Sicherheit hinzugefügt, die *Pfadoperationen* sind weiterhin dort verfügbar, wo sie sich befinden.

// Package-wide variables from generator "generated".
option go_package = "k8s.io/api/admissionregistration/v1";

// MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.
message MatchCondition {
  // Name is an identifier for this match condition, used for strategic merging of MatchConditions,

	responses <-chan Response
	cancel    context.CancelCauseFunc

	// Requests sent to the server.
	// If the handler is defined with 0 incoming capacity this will be nil.
	// Channel *must* be closed to signal the end of the stream.
	// If the request context is canceled, the stream will no longer process requests.
	// Requests sent cannot be used any further by the called.
	Requests chan<- []byte

	muxID uint64

// It does not encrypt empty ETags because such ETags indicate
// that the S3 client hasn't sent an ETag = MD5(object) and
// the backend can pick an ETag value.
func (key ObjectKey) SealETag(etag []byte) []byte {
	if len(etag) == 0 { // don't encrypt empty ETag - only if client sent ETag = MD5(object)
		return etag
	}
	var buffer bytes.Buffer
	mac := hmac.New(sha256.New, key[:])

    This defines the name of the cookie that should be provided in the request with
    the API key and integrates that into the OpenAPI documentation. It extracts
    the key value sent in the cookie automatically and provides it as the dependency
    result. But it doesn't define how to set that cookie.

    ## Usage

    Create an instance object and use that object as the dependency in `Depends()`.

        .receivedResponseAtMillis(receivedResponseMillis)
        .build()
    }

    companion object {
      /** Synthetic response header: the local time when the request was sent. */
      private val SENT_MILLIS = "${Platform.get().getPrefix()}-Sent-Millis"

      /** Synthetic response header: the local time when the response was received. */
      private val RECEIVED_MILLIS = "${Platform.get().getPrefix()}-Received-Millis"
    }

The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

It can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`), or equivalently with environment variables. For brevity we show only environment variables here:
