**FastAPI** 把 `OAuth2PasswordBearer` 识别为安全方案。因此，可以通过这种方式把它添加至 OpenAPI。

但 `OAuth2PasswordRequestForm` 只是可以自行编写的类依赖项，也可以直接声明 `Form` 参数。

但由于这种用例很常见，FastAPI 为了简便，就直接提供了对它的支持。

///

### 使用表单数据 { #use-the-form-data }

/// tip | 提示

`OAuth2PasswordRequestForm` 类依赖项的实例没有以空格分隔的长字符串属性 `scope`，但它支持 `scopes` 属性，由已发送的 scope 字符串列表组成。

本例没有使用 `scopes`，但开发者也可以根据需要使用该属性。

///

现在，即可使用表单字段 `username`，从（伪）数据库中获取用户数据。
