Also, there might be tools that expect and use it (now or in the future) and that might be useful for you or your users, now or in the future.

That's the benefit of standards...

## Dépendances { #dependencies }

FastAPI dépend de Pydantic et Starlette.

### Dépendances `standard` { #standard-dependencies }

Lorsque vous installez FastAPI avec `pip install "fastapi[standard]"`, il inclut le groupe `standard` de dépendances optionnelles :

还是使用 Python 类型声明，**FastAPI** 提供了（集成 Swagger UI 的）自动交互式文档。

注意，路径参数的类型是整数。

## 基于标准的好处，备选文档 { #standards-based-benefits-alternative-documentation }

**FastAPI** 使用 [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 生成概图，所以能兼容很多工具。

///

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

Before that, it only supported the keyword `example` with a single example. That is still supported by OpenAPI 3.1.0, but is deprecated and is not part of the JSON Schema standard. So you are encouraged to migrate `example` to `examples`. 🤓

You can read more at the end of this page.

/// tip

This is just standard Python, it's called a "type alias", it's actually not specific to **FastAPI**.

But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎

# 기능 { #features }

## FastAPI의 기능 { #fastapi-features }

**FastAPI**는 다음과 같은 기능을 제공합니다:

### 개방형 표준을 기반으로 { #based-on-open-standards }

* [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification): <dfn title="또한 다음으로도 불림: 엔드포인트, 라우트">경로</dfn> <dfn title="HTTP 메소드(POST, GET, PUT, DELETE 등)로도 알려짐">처리</dfn>, 매개변수, 요청 본문, 보안 등의 선언을 포함하여 API를 생성합니다.
* [**JSON Schema**](https://json-schema.org/)를 사용한 자동 데이터 모델 문서화(OpenAPI 자체가 JSON Schema를 기반으로 하기 때문입니다).

同樣地，只要使用那個 Python 型別宣告，**FastAPI** 就會提供自動、互動式的文件（整合 Swagger UI）。

注意路徑參數被宣告為整數。

## 基於標準的優勢與替代文件 { #standards-based-benefits-alternative-documentation }

而且因為產生的 schema 來自 [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 標準，有很多相容的工具可用。

# 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**。
