## Validation additionnelle

Nous allons imposer que bien que `q` soit un paramètre optionnel, dès qu'il est fourni, **sa longueur n'excède pas 50 caractères**.

## Importer `Query`

Pour cela, importez d'abord `Query` depuis `fastapi` :

      .isEqualTo(Settings.DEFAULT_INITIAL_WINDOW_SIZE.toLong())
    assertThat(connection.writeBytesMaximum)
      .isEqualTo(Settings.DEFAULT_INITIAL_WINDOW_SIZE.toLong())
    assertThat(stream1.writeBytesTotal)
      .isEqualTo(Settings.DEFAULT_INITIAL_WINDOW_SIZE.toLong())
    assertThat(stream1.writeBytesMaximum)
      .isEqualTo(Settings.DEFAULT_INITIAL_WINDOW_SIZE.toLong())

	GormValue(context.Context, *DB) clause.Expr
}

// GetDBConnector SQL db connector
type GetDBConnector interface {
	GetDBConn() (*sql.DB, error)
}

// Rows rows interface
type Rows interface {
	Columns() ([]string, error)
	ColumnTypes() ([]*sql.ColumnType, error)
	Next() bool
	Scan(dest ...interface{}) error
	Err() error
	Close() error
}

type ErrorTranslator interface {
	Translate(err error) error

      require(maxAge >= 0) { "maxAge < 0: $maxAge" }
      val maxAgeSecondsLong = timeUnit.toSeconds(maxAge.toLong())
      this.maxAgeSeconds = maxAgeSecondsLong.commonClampToInt()
    }

`app.add_middleware()` recebe uma classe de middleware como o primeiro argumento e quaisquer argumentos adicionais a serem passados para o middleware.

## Middlewares Integrados

**FastAPI** inclui vários middlewares para casos de uso comuns, veremos a seguir como usá-los.

/// note | Detalhes Técnicos

Para o próximo exemplo, você também poderia usar `from starlette.middleware.something import SomethingMiddleware`.

    ).hasMessage("timeout too small")
    assertThat(

          TimeUnit.MILLISECONDS,
        )
      },
    ).hasMessage("timeout too large")
  }

  @Test
  fun testDurationDuration() {
    assertThat(checkDuration("timeout", 0.milliseconds)).isEqualTo(0)
