### Requests simples

Cualquier request con un header `Origin`. En este caso, el middleware pasará el request a través de lo normal, pero incluirá los headers CORS adecuados en el response.

        LogStream.setInstance(testStream);

        final LogStream[] instances = new LogStream[10];
        Thread[] threads = new Thread[10];

        for (int i = 0; i < threads.length; i++) {
            final int index = i;
            threads[i] = new Thread(() -> {
                instances[index] = LogStream.getInstance();
            });
            threads[i].start();
        }

```

Ou como em Python 3.10 e versões superiores:

```Python
q: str | None = None
```

Por exemplo:

{* ../../docs_src/body_multiple_params/tutorial004_py310.py hl[26] *}

/// info | Informação

`Body` também possui todas as validações adicionais e metadados de parâmetros como em `Query`,`Path` e outras que você verá depois.
