## Múltiplos parâmetros de corpo { #multiple-body-parameters }

No exemplo anterior, as *operações de rota* esperariam um JSON no corpo contendo os atributos de um `Item`, exemplo:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

Mas você pode também declarar múltiplos parâmetros de corpo, por exemplo, `item` e `user`:

///

{* ../../docs_src/extra_models/tutorial003_py310.py hl[1,14:15,18:20,33] *}

### `Union` in Python 3.10 { #union-in-python-3-10 }

In this example we pass `Union[PlaneItem, CarItem]` as the value of the argument `response_model`.

<p>
Constants are of the form <code>const_<i>name</i></code>.
For example, given the Go declaration <code>const bufSize =
1024</code>, assembly code can refer to the value of this constant
as <code>const_bufSize</code>.
</p>

<p>
Field offsets are of the form <code><i>type</i>_<i>field</i></code>.
Struct sizes are of the form <code><i>type</i>__size</code>.
For example, consider the following Go definition:
</p>

<pre>

    bytesIn.writeUtf8("www.example.com")
  }

  private fun checkReadFirstRequestWithoutHuffman() {
    assertThat(hpackReader!!.headerCount).isEqualTo(1)

    // [  1] (s =  57) :authority: www.example.com
    val entry = hpackReader!!.dynamicTable[readerHeaderTableLength() - 1]!!
    checkEntry(entry, ":authority", "www.example.com", 57)

    // Table size: 57

#### Bulk Document API

**Endpoint**: `PUT /api/admin/documents/bulk`

**Format**: NDJSON (Newline-Delimited JSON)

**Example**:
```bash
# Create NDJSON file
cat > documents.ndjson << 'EOF'
{"url":"http://example.com/page1","title":"Page 1","content":"Content here..."}
{"url":"http://example.com/page2","title":"Page 2","content":"More content..."}
EOF

# Import via API

Você pode usar, por exemplo:

* `int`
* `float`
* `bool`
* `bytes`

### Módulo `typing` { #typing-module }

## Usando `Union` ou `Optional` { #using-union-or-optional }

Se, por algum motivo, seu código não puder usar `|`, por exemplo, se não for em uma anotação de tipo, mas em algo como `response_model=`, em vez de usar a barra vertical (`|`) você pode usar `Union` do `typing`.

Por exemplo, você poderia declarar que algo pode ser `str` ou `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):

*----+------+------+
| <<<maven.version>>> | The version number of the current Maven execution <(since 3.0.4)>. For example, "<<<3.0.5>>>". | <<<$\{maven.version\}>>> |
*----+------+------+
| <<<maven.build.version>>> | The full build version of the current Maven execution <(since 3.0.4)>. For example, "<<<Apache Maven 3.2.2 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19T14:51:28+01:00)>>>". | <<<$\{maven.build.version\}>>> |

    if log.is_file():
        os.remove(log)  # pragma: no cover
    response = client.post("/send-notification/foo@example.com")
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Notification sent in the background"}
    with open("./log.txt") as f:

`mc support inspect ALIAS/path/to/files`. This can for example be used to collect `xl.meta` from objects that are misbehaving. To collect `xl.meta` from a specific object, for example placed at `ALIAS/bucket/path/to/file.txt` append `/xl.meta`, for instance `mc support inspect ALIAS/bucket/path/to/file.txt/xl.meta`. All files can be collected, so this can also be used to retrieve `part.*` files, etc.

Wildcards can be used, for example `mc support inspect ALIAS/bucket/path/**/xl.meta` will...
