* 来自不同位置的**参数**声明：**headers**、**cookies**、**form 字段**和**文件**。
* 如何设置**校验约束**，如 `maximum_length` 或 `regex`。
* 功能强大且易用的 **<dfn title="也被称为：组件、资源、提供者、服务、可注入项">依赖注入</dfn>** 系统。
* 安全与认证，包括对 **OAuth2**、**JWT tokens** 和 **HTTP Basic** 认证的支持。
* 更高级（但同样简单）的 **多层嵌套 JSON 模型** 声明技巧（得益于 Pydantic）。
* 通过 [Strawberry](https://strawberry.rocks) 等库进行 **GraphQL** 集成。
* 许多额外特性（归功于 Starlette），例如：
    * **WebSockets**
    * 基于 HTTPX 和 `pytest` 的极其简单的测试
