## 使用 `Jinja2Templates`

* 导入 `Jinja2Templates`
* 创建可复用的 `templates` 对象
* 在返回模板的*路径操作*中声明 `Request` 参数
* 使用 `templates` 渲染并返回 `TemplateResponse`， 以键值对方式在 Jinja2 的 **context** 中传递 `request`

```Python hl_lines="4  11  15-16"
{!../../../docs_src/templates/tutorial001.py!}
```

!!! note "笔记"

    注意，必须为 Jinja2 以键值对方式在上下文中传递 `request`。因此，还要在*路径操作*中声明。

    Before FastAPI 0.108.0, Starlette 0.29.0, the `name` was the first parameter.

* Use o `template` que você criou para renderizar e retornar uma `TemplateResponse`, passe o nome do template, o request object, e um "context" dict com pares chave-valor a serem usados dentro do template do Jinja2.
