## 获取 `username` 和 `password` 的代码

接下来，使用 **FastAPI** 工具获取用户名与密码。

### `OAuth2PasswordRequestForm`

首先，导入 `OAuth2PasswordRequestForm`，然后，在 `/token` *路径操作* 中，用 `Depends` 把该类作为依赖项。

```Python hl_lines="4  76"
{!../../docs_src/security/tutorial003.py!}
```

`OAuth2PasswordRequestForm` 是用以下几项内容声明表单请求体的类依赖项：

* `username`
* `password`
* 可选的 `scope` 字段，由多个空格分隔的字符串组成的长字符串
* 可选的 `grant_type`
