# History, Design and Future

Some time ago, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">a **FastAPI** user asked</a>:

> What’s the history of this project? It seems to have come from nowhere to awesome in a few weeks [...]

Here's a little bit of that history.

# História, Design e Futuro

Há algum tempo, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">um usuário **FastAPI** perguntou</a>:

> Qual é a história desse projeto? Parece que surgiu do nada e se tornou incrível em poucas semanas [...]

Aqui está um pouco dessa história.

이전 스크린샷은 <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>를 찍은 것입니다.

하지만 똑같은 편집기 지원을 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>에서 받을 수 있거나, 대부분의 다른 편집기에서도 받을 수 있습니다:

public class SpnegoAuthenticator implements SsoAuthenticator {

    private static final Logger logger = LogManager.getLogger(SpnegoAuthenticator.class);

    protected static final String SPNEGO_INITIALIZED = "spnego.initialized";
    protected static final String SPNEGO_EXCLUDE_DIRS = "spnego.exclude.dirs";

这部分文档在 `/docs` 下的 Swagger API 文档中显示，并且会告诉外部开发者如何构建*外部 API*。

本例没有实现回调本身（只是一行代码），只有文档部分。

/// tip | "提示"

实际的回调只是 HTTP 请求。

实现回调时，要使用 <a href="https://www.encode.io/httpx/" class="external-link" target="_blank">HTTPX</a> 或 <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requests</a>。

///

## 编写回调文档代码

应用不执行这部分代码，只是用它来*记录 外部 API* 。

但，您已经知道用 **FastAPI** 创建自动 API 文档有多简单了。
