### 导入 `Query` 和 `Annotated` { #import-query-and-annotated }

为此，先导入：

- 从 `fastapi` 导入 `Query`
- 从 `typing` 导入 `Annotated`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | 信息

FastAPI 在 0.95.0 版本中添加了对 `Annotated` 的支持（并开始推荐使用）。

如果你的版本更旧，使用 `Annotated` 会报错。

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。

///

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### 运行应用 { #run-the-app }

你可以运行这个应用：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然后在 `/docs` UI 中，你能够看到 **FastAPI** 会用这些**模型**来**记录** API，并且还会用它们来**序列化**和**验证**数据。

<div class="screenshot">

        return UUID.randomUUID().toString().replace("-", StringUtil.EMPTY);
    }

    /**
     * Updates the user session with the provided user code.
     * This method registers the user info with the search log helper and updates the cookie.
     *
     * @param userCode the user code to associate with the session
     */
    protected void updateUserSessionId(final String userCode) {

# _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/
# you can define your messages here:
# e.g.

# info.xxx = ...
# _/_/_/_/_/_/_/_/_/_/
# ========================================================================================

errors.login_error = El nombre de usuario o la contraseña son incorrectos.

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

* Kodu okuyup kontrol edin; mantıklı mı bakın, **yerelde çalıştırın** ve gerçekten problemi çözüyor mu görün.

* Ardından bunu yaptığınızı belirten bir **yorum** yazın; böylece gerçekten kontrol ettiğinizi anlarım.
