- 對來自不同地方的**參數**進行宣告：像是 **headers**, **cookies**, **form 表單**以及**上傳檔案**。
- 如何設定 **驗證限制** 像是 `maximum_length` or `regex`。
- 簡單且非常容易使用的 **<abbr title="也被稱為元件、資源、提供者、服務或是注入">依賴注入</abbr>** 系統。
- 安全性和身份驗證，包含提供支援 **OAuth2**、**JWT tokens** 和 **HTTP Basic** 驗證。
- 更進階 (但同樣簡單) 的宣告 **多層次的巢狀 JSON 格式** (感謝 Pydantic)。
- **GraphQL** 與 <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> 以及其他的相關函式庫進行整合。

    * 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。
