val client = makeClient()
    makeRequest(client)

    // As of OkHttp 5 we now apply the ordering from the OkHttpClient, which defaults to MODERN_TLS
    // Clients might need a changed order, but can at least define a preferred order to override that default.
    val socketOrderedByDefaults =
      handshakeEnabledCipherSuites.sortedBy { ConnectionSpec.MODERN_TLS.cipherSuitesAsString!!.indexOf(it) }

Таким образом, вы можете объявлять глубоко вложенные JSON «объекты» с определёнными именами атрибутов, типами и валидацией.

Всё это может быть произвольно вложенным.

### Определение подмодели { #define-a-submodel }

Например, мы можем определить модель `Image`:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### Использование подмодели как типа { #use-the-submodel-as-a-type }

 maven.user.config.dir (system,default=${user.home}/.m2)
 maven.home            (system,user,default=${user.home}/m2)
 maven.repo.local      (system,user,default=${maven.user.config.dir}/repository)

 We need to define what happens in the when things are not setup correctly

 o ~/.m2 directory does not exist
 o ~/.m2/maven.properties does not exist
 o if they once existed but now to do not exist

### Orden de las etiquetas { #order-of-tags }

El orden de cada diccionario de metadata de etiqueta también define el orden mostrado en la interfaz de documentación.

Por ejemplo, aunque `users` iría después de `items` en orden alfabético, se muestra antes porque agregamos su metadata como el primer diccionario en la list.

      assertTaskWrapped(tasks);
      lastMethodCalled = "invokeAllTimeout";
      lastTimeoutInMillis = unit.toMillis(timeout);
      return inline.invokeAll(tasks, timeout, unit);
    }

    // Define the invokeAny methods to invoke the first task
    @Override
    public <T> T invokeAny(Collection<? extends Callable<T>> tasks)
        throws ExecutionException, InterruptedException {
      assertTaskWrapped(tasks);

* `expose_headers` - Indica quaisquer cabeçalhos de resposta que devem ser disponibilizados ao navegador. O padrão é `[]`.
* `max_age` - Define um tempo máximo em segundos para os navegadores armazenarem em cache as respostas CORS. O padrão é `600`.

O middleware responde a dois tipos específicos de solicitação HTTP...

SAM Conversions
---------------

When you use Java APIs from Kotlin you can operate on Java interfaces as if they were Kotlin
lambdas. The [feature][java_sams] is available for interfaces that define a Single Abstract Method
(SAM).

But when you use Kotlin APIs from Kotlin there’s no automatic conversion. Code that used SAM lambdas
with OkHttp 3.x: must use `object :` with OkHttp 4.x:

Kotlin calling OkHttp 3.x:

     *
     * @param <P>           the type of problem
     * @param maxCountLimit the maximum number of problems to preserve
     * @param filter        predicate to decide which problems to record
     * @return a new filtered problem collector instance
     */
    @Nonnull
    static <P extends BuilderProblem> ProblemCollector<P> create(int maxCountLimit, Predicate<? super P> filter) {

# Eventos de lifespan { #lifespan-events }

Você pode definir a lógica (código) que deve ser executada antes da aplicação **inicializar**. Isso significa que esse código será executado **uma vez**, **antes** de a aplicação **começar a receber requisições**.

   *   Iterator<E> i = queue.iterator(); // Must be in synchronized block
   *   while (i.hasNext()) {
   *     foo(i.next());
   *   }
   * }
   * }
   *
   * <p>Failure to follow this advice may result in non-deterministic behavior.
   *
   * <p>The returned queue will be serializable if the specified queue is serializable.
   *
   * @param queue the queue to be wrapped in a synchronized view
