In diesem Beispiel wird das Pydantic-Modell in ein `dict`, und das `datetime`-Objekt in ein `str` konvertiert.

## 来自前一个例子的`dict`

在前面的例子中, 我们从依赖项 ("可依赖对象") 中返回了一个 `dict`:

//// tab | Python 3.10+

```Python hl_lines="7"
{!> ../../docs_src/dependencies/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="9"
{!> ../../docs_src/dependencies/tutorial001.py!}
```

////

但是后面我们在路径操作函数的参数 `commons` 中得到了一个 `dict`。

我们知道编辑器不能为 `dict` 提供很多支持(比如补全)，因为编辑器不知道 `dict` 的键和值类型。

对此，我们可以做的更好...

pkg syscall (darwin-amd64), func Fchflags(string, int) error
pkg syscall (darwin-amd64-cgo), const ImplementsGetwd = false
pkg syscall (darwin-amd64-cgo), func Fchflags(string, int) error
pkg syscall (freebsd-386), const AF_MAX = 38
pkg syscall (freebsd-386), const DLT_MATCHING_MAX = 242
pkg syscall (freebsd-386), const ELAST = 94
pkg syscall (freebsd-386), const ImplementsGetwd = false
pkg syscall (freebsd-386), const O_CLOEXEC = 0

把下面的示例代码复制到 `main.py`：

//// tab | Python 3.9+

```

////

//// tab | Python 3.8+

```Python
{!> ../../docs_src/security/tutorial001_an.py!}
```

////

//// tab | Python 3.8+ non-Annotated

/// tip

尽可能选择使用 `Annotated` 的版本。

## 运行

让我们从一个简单的 FastAPI 应用开始：

//// tab | Python 3.9+

```Python hl_lines="7-9  12-13  16-17  21"
{!> ../../docs_src/generate_clients/tutorial001_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="9-11  14-15  18  19  23"
{!> ../../docs_src/generate_clients/tutorial001.py!}
```

////

请注意，*路径操作* 定义了他们所用于请求数据和回应数据的模型，所使用的模型是`Item` 和 `ResponseMessage`。
