#### FastAPI's `HTTPException` vs Starlette's `HTTPException`

**FastAPI** has its own `HTTPException`.

And **FastAPI**'s `HTTPException` error class inherits from Starlette's `HTTPException` error class.

     * </ul>
     * Example filter expression: <code>"h(5);s;e(org.foo:bar:1)</code> will cause: ranges are filtered for "top 5" (instead

# 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>。
