No próximo capítulo, você verá uma implementação realmente segura, com hash de senha e tokens <abbr title="JSON Web Tokens">JWT</abbr>.

Mas, por enquanto, vamos nos concentrar nos detalhes específicos de que precisamos.

* Підтримка **WebSocket**.
* Фонові задачі у процесі.
* Події запуску та завершення роботи.
* Клієнт для тестування, побудований на HTTPX.
* Підтримка **CORS**, **GZip**, статичних файлів, потокових відповідей.
* Підтримка **сесій** і **cookie**.
* 100% покриття тестами.
* 100% анотована типами кодова база.

## Можливості Pydantic

        assertNotNull(type1Token);
        assertTrue(type1Token.length > 0);

        // Decode the token to verify its properties
        Type1Message type1Message = new Type1Message(type1Token);
        // Type1Message ORs default flags with provided flags; ensure expected bits are present
        assertTrue((type1Message.getFlags() & context.ntlmsspFlags) == context.ntlmsspFlags);
        assertEquals(domain, type1Message.getSuppliedDomain());
    }

### Criar uma Dependência de Sessão

Uma **`Session`** é o que armazena os **objetos na memória** e acompanha as alterações necessárias nos dados, para então **usar o `engine`** para se comunicar com o banco de dados.

changes we've made over time to OkHttp's default TLS options.

[OkHttp 3.14][OkHttp314]
------------------------

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.

##### RESTRICTED_TLS cipher suites

 * TLS_AES_128_GCM_SHA256[¹][tlsv13_only]
 * TLS_AES_256_GCM_SHA384[¹][tlsv13_only]
 * TLS_CHACHA20_POLY1305_SHA256[¹][tlsv13_only]

This is probably not as important or necessary if you use `Annotated`.

///

Here's a **small trick** that can be handy, but you won't need it often.

If you want to:

* declare the `q` query parameter without a `Query` nor any default value
* declare the path parameter `item_id` using `Path`
* have them in a different order
* not use `Annotated`

...Python has a little special syntax for that.

                    () -> NtlmAuthenticator.requestNtlmPasswordAuthentication(eq(mockNtlmAuthenticator), eq("locationHint"), eq(null)));
        }
    }

    @Test
    @DisplayName("Should return false if neither renewable nor NTLM authentication succeeds")
    void testRenewCredentials_NoRenewalPossible() {
        // Ensure credentials are not renewable

## Mais informações sobre retornos OpenAPI

Para verificar exatamente o que você pode incluir nos retornos, você pode conferir estas seções na especificação do OpenAPI:

		return nil
	}
	sseKMS := crypto.S3KMS.IsEncrypted(objInfo.UserDefined)
	sseS3 := crypto.S3.IsEncrypted(objInfo.UserDefined)
	if !sseKMS && !sseS3 { // neither sse-s3 nor sse-kms disallowed
		return errInvalidEncryptionParameters
	}
	if sseKMS && r.Encryption.Type == sses3 { // previously encrypted with sse-kms, now sse-s3 disallowed
		return errInvalidEncryptionParameters
	}

And you could do this even if the data type in the request is not JSON.

For example, in this application we don't use FastAPI's integrated functionality to extract the JSON Schema from Pydantic models nor the automatic validation for JSON. In fact, we are declaring the request content type as YAML, not JSON:
