## Do not Separate Schemas { #do-not-separate-schemas }

Now, there are some cases where you might want to have the **same schema for input and output**.

# Generating SDKs { #generating-sdks }

Because **FastAPI** is based on the **OpenAPI** specification, its APIs can be described in a standard format that many tools understand.

This makes it easy to generate up-to-date **documentation**, client libraries (<abbr title="Software Development Kits">**SDKs**</abbr>) in multiple languages, and **testing** or **automation workflows** that stay in sync with your code.

- To be able to reliably use S3 multipart APIs feature of the SDKs without re-inventing the wheel of pre-signing the each URL in multipart API. This is very tedious to implement with all the scenarios of fault tolerance that's already implemented by the client SDK. The general client SDKs don't support multipart with presigned URLs.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,
    APIKeyQuery,
    HTTPAuthorizationCredentials,
    HTTPBasic,

# SDK 생성하기 { #generating-sdks }

**FastAPI**는 **OpenAPI** 사양을 기반으로 하므로, FastAPI의 API는 많은 도구가 이해할 수 있는 표준 형식으로 설명할 수 있습니다.

덕분에 여러 언어용 클라이언트 라이브러리(<abbr title="Software Development Kits - 소프트웨어 개발 키트">**SDKs**</abbr>), 최신 **문서**, 그리고 코드와 동기화된 **테스트** 또는 **자동화 워크플로**를 쉽게 생성할 수 있습니다.

이 가이드에서는 FastAPI 백엔드용 **TypeScript SDK**를 생성하는 방법을 배웁니다.

# 生成 SDK { #generating-sdks }

因为 **FastAPI** 基于 **OpenAPI** 规范，它的 API 可以用许多工具都能理解的标准格式来描述。

这让你可以轻松生成最新的**文档**、多语言的客户端库（<abbr title="Software Development Kits - 软件开发工具包">**SDKs**</abbr>），以及与代码保持同步的**测试**或**自动化工作流**。

本指南将带你为 FastAPI 后端生成一个 **TypeScript SDK**。

## 开源 SDK 生成器 { #open-source-sdk-generators }

一个功能多样的选择是 [OpenAPI Generator](https://openapi-generator.tech/)，它支持**多种编程语言**，可以根据你的 OpenAPI 规范生成 SDK。
