# 特性 { #features }

## FastAPI 特性 { #fastapi-features }

**FastAPI** 提供了以下内容：

### 基于开放标准 { #based-on-open-standards }

* [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification) 用于创建 API，包含对<dfn title="也称为：端点、路由">路径</dfn> <dfn title="也称为 HTTP 方法，如 POST、GET、PUT、DELETE">操作</dfn>、参数、请求体、安全等的声明。
* 使用 [**JSON Schema**](https://json-schema.org/) 自动生成数据模型文档（因为 OpenAPI 本身就是基于 JSON Schema 的）。
* 经过了缜密的研究后围绕这些标准而设计。并非狗尾续貂。
* 这也允许了在很多语言中自动**生成客户端代码**。

**FastAPI** 提供了以下內容：

### 建立在開放標準的基礎上 { #based-on-open-standards }

* 使用 [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification) 來建立 API，包含 <dfn title="也稱為：端點、路由">路徑</dfn>、<dfn title="也稱為 HTTP 方法，例如 POST、GET、PUT、DELETE">操作</dfn>、參數、請求內文、安全性等宣告。
* 使用 [**JSON Schema**](https://json-schema.org/)（因為 OpenAPI 本身就是基於 JSON Schema）自動生成資料模型文件。
* 經過縝密的研究後圍繞這些標準進行設計，而不是事後在已有系統上附加的一層功能。
