它们会为每个*路径操作*进行单独检查。

## 查看文档

打开 API 文档，进行身份验证，并指定要授权的作用域。

<img src="/img/tutorial/security/image11.png">

没有选择任何作用域，也可以进行**身份验证**，但访问 `/uses/me` 或 `/users/me/items` 时，会显示没有足够的权限。但仍可以访问 `/status/`。

如果选择了作用域 `me`，但没有选择作用域 `items`，则可以访问 `/users/me/`，但不能访问 `/users/me/items`。

这就是通过用户提供的令牌使用第三方应用访问这些*路径操作*时会发生的情况，具体怎样取决于用户授予第三方应用的权限。

本例使用 OAuth2 **密码**流。

这种方式适用于登录我们自己的应用，最好使用我们自己的前端。
