* 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`， 传递模板的名称、request对象以及一个包含多个键值对（用于Jinja2模板）的"context"字典，

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

/// note | "笔记"

在FastAPI 0.108.0，Starlette 0.29.0之前，`name`是第一个参数。
并且，在此之前，`request`对象是作为context的一部分以键值对的形式传递的。

///

/// tip | "提示"

通过声明 `response_class=HTMLResponse`，API 文档就能识别响应的对象是 HTML。
