OpenAPI (anteriormente conocido como Swagger) es la especificación abierta para construir APIs (ahora parte de la Linux Foundation).

**FastAPI** se basa en **OpenAPI**.

Eso es lo que hace posible tener múltiples interfaces de documentación interactiva automática, generación de código, etc.

OpenAPI tiene una forma de definir múltiples "esquemas" de seguridad.

        assertDoesNotThrow(() -> channelManager.handleChannelFailure(channel, error));
    }

    @Test
    void testEstablishReplacementChannel() {
        // Should not throw exception even when no interfaces are available
        assertDoesNotThrow(() -> channelManager.establishReplacementChannel());
    }

    @Test
    void testGetChannelForTransport() {

* Esquemas que serán parte del esquema de OpenAPI generado y usados por la <abbr title="User Interfaces">UIs</abbr> de documentación automática.

## Documentación automática

Los JSON Schemas de tus modelos serán parte del esquema OpenAPI generado y se mostrarán en la documentación API interactiva:

the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official

    AccessibleObject.setAccessible(methods, true);

      // Interfaces can have default methods that aren't abstract.

فریم ورک **FastAPI** بر اساس **OpenAPI** است.

این خاصیت، امکان دارد تا چندین رابط مستندات تعاملی خودکار(automatic interactive documentation interfaces)، تولید کد و غیره وجود داشته باشد.

مشخصه OpenAPI روشی برای تعریف چندین "schemes" دارد.

// toString - Safely convert interface to string without causing panic.
func toString(val any) string {
	switch v := val.(type) {
	case string:
		return v
	default:

	}
}

// toLowerString - safely convert interface to lower string
func toLowerString(val any) string {
	return strings.ToLower(toString(val))
}

// toInteger _ Safely convert interface to integer without causing panic.
