* **Editor support**.
* **Type checks**.

...and **FastAPI** uses the same declarations to:

* **Define requirements**: from request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convert data**: from the request to the required type.
* **Validate data**: coming from each request:

* **Typ-Prüfungen**.

... und **FastAPI** verwendet dieselben Deklarationen, um:

* **Anforderungen** zu definieren: aus <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr>-Pfadparametern, Query-Parametern, Headern, Bodys, Abhängigkeiten, usw.
* **Daten umzuwandeln**: aus dem Request in den erforderlichen Typ.
* **Daten zu validieren**: aus jedem Request:

	}

	defer adminTestBed.TearDown()

	// Initialize admin peers to make admin RPC calls.
	globalMinioAddr = "127.0.0.1:9000"

	// Prepare query params for set-config mgmt REST API.
	queryVal := url.Values{}
	queryVal.Set("info", "")

	req, err := buildAdminRequest(queryVal, http.MethodGet, "/info", 0, nil)
	if err != nil {

  }

  AbstractBiMap<V, K> makeInverse(Map<V, K> backward) {
    return new Inverse<>(backward, this);
  }

  void setInverse(AbstractBiMap<V, K> inverse) {
    this.inverse = inverse;
  }

  // Query Operations (optimizations)

  @Override
  public boolean containsValue(@Nullable Object value) {
    return inverse.containsKey(value);
  }

  // Modification Operations

  @CanIgnoreReturnValue

Pero podría haber casos en los que quieras poder establecer parámetros en la dependencia, sin tener que declarar muchas funciones o clases diferentes.

Imaginemos que queremos tener una dependencia que revise si el parámetro de query `q` contiene algún contenido fijo.

Pero queremos poder parametrizar ese contenido fijo.

## Una *instance* "callable" { #a-callable-instance }

## Vorteile { #benefits }

Wenn Sie die automatisch generierten Clients verwenden, erhalten Sie **Autovervollständigung** für:

* Methoden.
* Request-Payloads im Body, Query-Parameter, usw.
* Response-Payloads.

Sie erhalten auch **Inline-Fehlerberichte** für alles.

* **Editör desteği**.
* **Tip kontrolleri**.

...ve **FastAPI** aynı bildirimleri şunlar için de kullanır:

* **Gereksinimleri tanımlamak**: request path parameters, query parameters, headers, bodies, bağımlılıklar (dependencies), vb.
* **Veriyi dönüştürmek**: request'ten gerekli tipe.
* **Veriyi doğrulamak**: her request'ten gelen veriyi:

     *     <li>"release_or_snapshot" - the default</li>
     *     <li>"release" - query only release repositories to discover versions</li>
     *     <li>"snapshot" - query only snapshot repositories to discover versions</li>
     * </ul>
     * Default (when unset) is using request carried nature. Hence, this configuration really makes sense with value

# Transmitir dados { #stream-data }

Se você quer transmitir dados que podem ser estruturados como JSON, você deveria [Transmitir JSON Lines](../tutorial/stream-json-lines.md).

Mas se você quer transmitir dados binários puros ou strings, veja como fazer.
