Das ist natürlich nicht optimal und man würde das nicht in der Produktion machen.

In der Produktion hätten Sie eine der oben genannten Optionen.

Aber es ist die einfachste Möglichkeit, sich auf die Serverseite von WebSockets zu konzentrieren und ein funktionierendes Beispiel zu haben:

{* ../../docs_src/websockets/tutorial001.py hl[2,6:38,41:43] *}

            return null;
        }).when(mockDcerpcHandle).sendrecv(any(MsrpcLsarClose.class));

        // Act
        handle.close();

        // Assert
        // Verify sendrecv was called once for open and once for close
        verify(mockDcerpcHandle, times(1)).sendrecv(any(MsrpcLsarOpenPolicy2.class));
        verify(mockDcerpcHandle, times(1)).sendrecv(any(MsrpcLsarClose.class));
    }

    @Test

So, it was a complete additional system.

It is not very popular or used nowadays.

## OpenAPI { #openapi }

OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation).

**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

### Responsemodell deaktivieren

Beim Beispiel oben fortsetzend, mögen Sie vielleicht die standardmäßige Datenvalidierung, -Dokumentation, -Filterung, usw., die von FastAPI durchgeführt wird, nicht haben.

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Por baixo dos panos, o código `open("./somefile.txt")` cria um objeto que é chamado de "Gerenciador de Contexto".
