#### O `HTTPException` do FastAPI vs o `HTTPException` do Starlette.

O **FastAPI** tem o seu próprio `HTTPException`.

E a classe de erro `HTTPException` do **FastAPI** herda da classe de erro do `HTTPException` do Starlette.

A diferença entre os dois é a de que o `HTTPException` do **FastAPI** permite que você adicione *headers* que serão incluídos nas *responses*.

  /**
   * Returns the result of applying this predicate to {@code input} (Java 8+ users, see notes in the
   * class documentation above). This method is <i>generally expected</i>, but not absolutely
   * required, to have the following properties:
   *
   * <ul>
   *   <li>Its execution does not cause any observable side effects.
   *   <li>The computation is <i>consistent with equals</i>; that is, {@link Objects#equal

    // For the socket connect timeout case we do not try the same host with a different
    // ConnectionSpec: we assume it is unreachable.
    e is InterruptedIOException -> false

    // If the problem was a CertificateException from the X509TrustManager, do not retry.
    e is SSLHandshakeException && e.cause is CertificateException -> false

    // e.g. a certificate pinning error.

  /**
   * Invoked when a {@code Future} computation fails or is canceled.
   *
   * <p>If the future's {@link Future#get() get} method throws an {@link ExecutionException}, then
   * the cause is passed to this method. Any other thrown object is passed unaltered.

À moins que vous ne spécifiiez explicitement un type de média différent dans votre paramètre `responses`, FastAPI supposera que la réponse a le même type de média que la classe de réponse principale (par défaut `application/json`).

Mais si vous avez spécifié une classe de réponse personnalisée avec `None` comme type de média, FastAPI utilisera `application/json` pour toute réponse supplémentaire associée à un modèle.
