## Errores de dependencias y valores de retorno

Puedes usar las mismas *funciones* de dependencia que usas normalmente.

### Requisitos de dependencia

Pueden declarar requisitos de request (como headers) u otras sub-dependencias:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[8,13] *}

### Lanzar excepciones

Estas dependencias pueden `raise` excepciones, igual que las dependencias normales:

	json.NewEncoder(w).Encode(map[string]string{
		"error": fmt.Sprintf("%v", err),
	})
}

type Result struct {
	Result bool `json:"result"`
}

func mainHandler(w http.ResponseWriter, r *http.Request) {
	body, err := io.ReadAll(r.Body)
	if err != nil {
		writeErrorResponse(w, err)
		return
	}

	var out bytes.Buffer
	json.Indent(&out, body, "", "  ")
	fmt.Printf("Received JSON payload:\n%s\n", out.String())

* `list`/`watch` API requests with a `fieldSelector` that specifies `metadata.name` can now be authorized as requests for an individual named resource ([#63469](https://github.com/kubernetes/kubernetes/pull/63469), [@wojtek-t](https://github.com/wojtek-t))

      distributionSha256Result=true
    fi
  else
    echo "Checksum validation was requested but neither 'sha256sum' or 'shasum' are available." >&2
    echo "Please install either command, or disable validation by removing 'distributionSha256Sum' from your maven-wrapper.properties." >&2
    exit 1
  fi

# Header-Parameter

So wie `Query`-, `Path`-, und `Cookie`-Parameter können Sie auch <abbr title='Header – Kopfzeilen, Header, Header-Felder: Schlüssel-Wert-Metadaten, die vom Client beim Request, und vom Server bei der Response gesendet werden'>Header</abbr>-Parameter definieren.

## `Header` importieren

Importieren Sie zuerst `Header`:

## `Header`-Parameter deklarieren
