# Advanced User Guide { #advanced-user-guide }

## Additional Features { #additional-features }

The main [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} should be enough to give you a tour through all the main features of **FastAPI**.

In the next sections you will see other options, configurations, and additional features.

### 4.2 Lease Context Structure
```java
package jcifs.internal.smb2.lease;

import jcifs.internal.smb2.create.Smb2CreateContext;

public class Smb2LeaseContext extends Smb2CreateContext {
    // Context name for lease request
    public static final String NAME_REQUEST = "RqLs";

import jcifs.CIFSContext;
import jcifs.SmbConstants;
import jcifs.SmbPipeHandle;
import jcifs.SmbPipeResource;
import jcifs.context.SingletonContext;
import jcifs.internal.smb1.com.SmbComNTCreateAndX;
import jcifs.internal.smb1.com.SmbComNTCreateAndXResponse;

@ExtendWith(MockitoExtension.class)
class SmbNamedPipeTest {

    // Creates a minimal valid CIFS context that does not perform I/O by itself

Por padrão, o **FastAPI** irá converter automaticamente o valor do retorno para JSON utilizando o `jsonable_encoder` explicado em [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Então, por baixo dos panos, ele incluiria esses dados compatíveis com JSON (e.g. um `dict`) dentro de uma `JSONResponse` que é utilizada para enviar uma resposta para o cliente.

По этой причине обычно их передают через переменные окружения, которые считываются приложением.

Чтобы понять, что такое переменные окружения, вы можете прочитать [Переменные окружения](../environment-variables.md){.internal-link target=_blank}.
