## 安装依赖项

安装 `jinja2`：

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

如需使用静态文件，还要安装 `aiofiles`：

<div class="termy">

```console
$ pip install aiofiles

---> 100%
```

</div>

## 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

│   ├── __init__.py
│   ├── main.py
└── static
    ├── redoc.standalone.js
    ├── swagger-ui-bundle.js
    └── swagger-ui.css
```

### 安装 `aiofiles`

现在，安装 `aiofiles`：


<div class="termy">

```console
$ pip install aiofiles

---> 100%
```

</div>

### 静态文件服务

* 导入 `StaticFiles`
* 在指定路径下**挂载** `StaticFiles()` 实例
