在使用 `Annotated` 之前，请确保先[升级 FastAPI 版本](../deployment/versions.md#upgrading-the-fastapi-versions)到至少 0.95.1。

## 在 `q` 参数的类型中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

还记得我之前在[Python 类型简介](../python-types.md#type-hints-with-metadata-annotations)中说过可以用 `Annotated` 给参数添加元数据吗？

现在正是与 FastAPI 搭配使用它的时候。🚀

我们之前的类型标注是：

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

我们要做的是用 `Annotated` 把它包起来，变成：

        *   `tf.math.argmin`/`tf.math.argmax` for input data type `tf.bool` on
            CPU.
        *   `tf.nn.gelu` op for output data type `tf.float32` and quantization
            on CPU.
    *   Add nominal support for unsigned 16-bit integer tensor types. Note that
        very few TFLite kernels support this type natively, so its use in mobile
        ML authoring is generally discouraged.

     * Adds a password validation error message to the messages object based on the error key.
     *
     * @param messages the FessMessages object to add the error to
     * @param errorKey the error key identifying the type of password validation error
     */
    protected void addPasswordValidationError(final FessMessages messages, final String errorKey) {
        switch (errorKey) {
        case "errors.password_length":

If you install Typer CLI, you can install completion with:

<div class="termy">

```console
$ typer --install-completion

zsh completion installed in /home/user/.bashrc.
Completion will take effect once you restart the terminal.
```

</div>

### Docs Structure

The documentation uses [MkDocs](https://www.mkdocs.org/).

```

但因為我們在使用 `Annotated`，我們可以把這個 `Annotated` 的值存到一個變數中，並在多個地方重複使用：

{* ../../docs_src/dependencies/tutorial001_02_an_py310.py hl[12,16,21] *}

/// tip | 提示

這只是標準的 Python，用的是所謂的「型別別名 (type alias)」，其實和 **FastAPI** 本身無關。

但因為 **FastAPI** 是建立在 Python 標準之上（包含 `Annotated`），你就可以在程式碼中使用這個技巧。😎

///

這些依賴依然會如預期運作，而最棒的是「型別資訊會被保留」，代表你的編輯器仍能提供「自動完成」、「即時錯誤」等功能，像 `mypy` 等其他工具也一樣受益。
