Some of them also ✨ [**sponsor FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨, this ensures the continued and healthy **development** of FastAPI and its **ecosystem**.

And it shows their true commitment to FastAPI and its **community** (you), as they not only want to provide you a **good service** but also want to make sure you have a **good and healthy framework**, FastAPI. 🙇

Ein besonderer Vorteil, der nicht unbedingt offensichtlich ist, besteht darin, dass Sie für Ihre API **Clients generieren** können (manchmal auch <abbr title="Software Development Kits">**SDKs**</abbr> genannt), für viele verschiedene **Programmiersprachen**.

## OpenAPI-Client-Generatoren

Es gibt viele Tools zum Generieren von Clients aus **OpenAPI**.

# 生成客户端

因为 **FastAPI** 是基于OpenAPI规范的，自然您可以使用许多相匹配的工具，包括自动生成API文档 (由 Swagger UI 提供)。

一个不太明显而又特别的优势是，你可以为你的API针对不同的**编程语言**来**生成客户端**(有时候被叫做 <abbr title="Software Development Kits">**SDKs**</abbr> )。

## OpenAPI 客户端生成

有许多工具可以从**OpenAPI**生成客户端。

一个常见的工具是 <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>。
