And it will probably vary a lot from one app to the next.

It could be just one or two lines of code, like:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

{!> ../../docs_src/body_nested_models/tutorial004.py!}
```

////

Это означает, что **FastAPI** будет ожидать тело запроса, аналогичное этому:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

///

Você pode adicionar um `title`:

```Python hl_lines="10"
{!../../docs_src/query_params_str_validations/tutorial007.py!}
```

E uma `description`:

```Python hl_lines="13"
{!../../docs_src/query_params_str_validations/tutorial008.py!}
```

## Apelidos (alias) de parâmetros

Imagine que você queira que um parâmetro tenha o nome `item-query`.

그리고 어트리뷰트의 타입으로 사용할 수 있습니다:

```Python hl_lines="20"
{!../../docs_src/body_nested_models/tutorial004.py!}
```

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

```Python hl_lines="20"
{!> ../../docs_src/body_nested_models/tutorial004.py!}
```

////

This would mean that **FastAPI** would expect a body similar to:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

E provavelmente variará muito de um aplicativo para o outro.

Poderia ser apenas uma ou duas linhas de código, como:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

  tests_failed = 'tests_failed'
  build_failed = 'build_failed'
  passed = 'passed'


def parse_args() -> argparse.Namespace:
  """Parses the commandline args."""
  parser = argparse.ArgumentParser(
      description='Extracts ResultStore links from a build log.\n'
                  'These can be then printed out, and/or output into a '
                  'JUnit-based XML file inside a specified directory.')

            )
            definitions.update(m_definitions)
            model_name = model_name_map[model]
            if "description" in m_schema:
                m_schema["description"] = m_schema["description"].split("\f")[0]
            definitions[model_name] = m_schema
        return definitions

    def is_pv1_scalar_field(field: ModelField) -> bool:

        }
    }

    public interface ContentTransformer {
        /**

         * @param source The source value
