#### Unpacking a `dict` { #unpacking-a-dict }

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unpack" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

Você também pode adicionar cabeçalhos quando retornar uma `Response` diretamente.

Crie uma resposta conforme descrito em [Retornar uma resposta diretamente](response-directly.md){.internal-link target=_blank} e passe os cabeçalhos como um parâmetro adicional:

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}

  protected V get(K key) {
    return getMap().get(key);

# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

        networkExplorer.init(servletConfig);

        // Setup authentication
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(SingletonContext.getInstance(), "DOMAIN", "user", "pass");
        when(session.getAttribute("npa-workgroup")).thenReturn(auth);
        when(request.getPathInfo()).thenReturn("/workgroup/server/share/");

        networkExplorer.doGet(request, response);

logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();
```

You can change the log level at any time by calling `setLevel()`.

To log to a custom location, pass a `Logger` instance to the constructor.
```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor(new Logger() {
  @Override public void log(String message) {
    Timber.tag("OkHttp").d(message);
  }
});
```

# Increase the V8 stack size from the default of 984K
# to 8192K to ensure all tests can pass without hitting
# stack size limits.

**FastAPI** will create the object of type `BackgroundTasks` for you and pass it as that parameter.

## Create a task function { #create-a-task-function }

Create a function to be run as the background task.

It is just a standard function that can receive parameters.

### Arquivo de teste estendido

Você pode então atualizar `test_main.py` com os testes estendidos:

{* ../../docs_src/app_testing/app_b/test_main.py *}

Sempre que você precisar que o cliente passe informações na requisição e não souber como, você pode pesquisar (no Google) como fazer isso no `httpx`, ou até mesmo como fazer isso com `requests`, já que o design do HTTPX é baseado no design do Requests.
