## Réponses supplémentaires

Vous avez probablement vu comment déclarer le `response_model` et le `status_code` pour une *opération de chemin*.

Cela définit les métadonnées sur la réponse principale d'une *opération de chemin*.

Vous pouvez également déclarer des réponses supplémentaires avec leurs modèles, codes de statut, etc.

== Adding external dependencies

Init scripts can also declare dependencies with the `initscript()` method, passing in a closure that declares the init script classpath.

Declaring external dependencies for an init script:

====
include::sample[dir="snippets/initScripts/externalDependency/kotlin",files="init.gradle.kts[tags=declare-classpath]"]

// receiver type acts as an implicit declaration of the type parameters
// for the receiver type. In the example below, method m1 on type T1 has
// the receiver type T1[A] which declares the type parameter A for use
// with this method. That is, within the method m1, A stands for the
// actual type argument provided to an instantiated T1.
func (t T1[A]) m1() A { return t.a }

     * Dependencies declared on this configuration are present during compilation
     * and runtime, and are exposed as part of the feature's API variant.
     *
     * @return null if {@link #withApi()} has not been called.
     */
    @Nullable
    Configuration getApiConfiguration();

    /**
     * Gets the dependency configuration for which to declare compile-only API dependencies.

// Does not compile.

package main

func notused(x interface{}) {
	// The first t is in a different scope than the 2nd t; it cannot
	// be accessed (=> declared and not used error); but it is legal
	// to declare it.
	switch t := 0; t := x.(type) { // ERROR "declared and not used"
	case int:
		_ = t // this is using the t of "t := x.(type)"
	}

	TLS Instance = "TLS"
	// UDP declares that the port uses UDP.
	// Note that UDP protocol is not currently supported by the proxy.
	UDP Instance = "UDP"
	// Mongo declares that the port carries MongoDB traffic.
	Mongo Instance = "Mongo"
	// Redis declares that the port carries Redis traffic.
	Redis Instance = "Redis"
	// MySQL declares that the port carries MySQL traffic.
	MySQL Instance = "MySQL"
	// HBONE declares that the port carries HBONE traffic.

}

// OptionalVariableDeclarations declares which optional CEL variables
// are declared for an expression.
type OptionalVariableDeclarations struct {
	// HasParams specifies if the "params" variable is declared.
	// The "params" variable may still be bound to "null" when declared.
	HasParams bool
	// HasAuthorizer specifies if the "authorizer" and "authorizer.requestResource"
	// variables are declared. When declared, the authorizer variables are

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

**FastAPI** will use that *temporal* response to extract the status code (also cookies and headers), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare singular values to be received as part of the body.

		var x2 /* ERROR "declared and not used" */ int
		x1 = 1
		(x2) = 2

		y1 /* ERROR "declared and not used" */ := 1
		y2 /* ERROR "declared and not used" */ := 2
		y1 = 1
		(y1) = 2
	}

	if x /* ERROR "declared and not used" */ := 0; a < b {}

	switch x /* ERROR "declared and not used" */, y := 0, 1; a {
	case 0:
		_ = y
	case 1:
		x /* ERROR "declared and not used" */ := 0
	}
