* 所有的这些*路径操作*都将在自身之前计算/执行 `dependencies` 列表。
    * 如果你还在一个具体的*路径操作*中声明了依赖项，**它们也会被执行**。
    * 路由器的依赖项最先执行，然后是[装饰器中的 `dependencies`](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}，再然后是普通的参数依赖项。
    * 你还可以添加[具有 `scopes` 的 `Security` 依赖项](../advanced/security/oauth2-scopes.md){.internal-link target=_blank}。

/// tip

在 `APIRouter`中具有 `dependencies` 可以用来，例如，对一整组的*路径操作*要求身份认证。即使这些依赖项并没有分别添加到每个路径操作中。

Então, as colocamos em seu próprio módulo de `dependencies` (`app/dependencies.py`).

Agora usaremos uma dependência simples para ler um cabeçalho `X-Token` personalizado:
