在*路径操作装饰器*中使用 `dependencies` 参数，可以确保在执行依赖项的同时，避免编辑器显示错误提示。

使用路径装饰器依赖项还可以避免开发新人误会代码中包含无用的未使用参数。

///

/// info | "说明"

本例中，使用的是自定义响应头 `X-Key` 和 `X-Token`。

但实际开发中，尤其是在实现安全措施时，最好使用 FastAPI 内置的[安全工具](../security/index.md){.internal-link target=_blank}（详见下一章）。

## 依赖项错误和返回值

路径装饰器依赖项也可以使用普通的依赖项*函数*。

### 依赖项的需求项

路径装饰器依赖项可以声明请求的需求项（比如响应头）或其他子依赖项：
