If you have a different use case that needs to exit early from a dependency with `yield`, please create a <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">GitHub Discussion Question</a> with your specific use case and why you would benefit from having early closing for dependencies with `yield`.

## 特殊的类型和校验

除了普通的单一值类型（如 `str`、`int`、`float` 等）外，你还可以使用从 `str` 继承的更复杂的单一值类型。

要了解所有的可用选项，请查看关于 <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">来自 Pydantic 的外部类型</a> 的文档。你将在下一章节中看到一些示例。

例如，在 `Image` 模型中我们有一个 `url` 字段，我们可以把它声明为 Pydantic 的 `HttpUrl`，而不是 `str`：

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

    assert response.json() == snapshot(
        {
            "detail": [
                {
                    "type": "extra_forbidden",
                    "loc": ["header", "tool"],
                    "msg": "Extra inputs are not permitted",
                    "input": "plumbus",
                }
            ]
        }
    )


def test_openapi_schema(client: TestClient):
    response = client.get("/openapi.json")

## Instale manipuladores de exceções customizados { #install-custom-exception-handlers }

Você pode adicionar manipuladores de exceção customizados com <a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">a mesma seção de utilidade de exceções presentes no Starlette</a>.

Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).
