### CORS 预检请求 { #cors-preflight-requests }

这是些带有 `Origin` 和 `Access-Control-Request-Method` 请求头的 `OPTIONS` 请求。

在这种情况下，中间件将拦截传入的请求并进行响应，出于提供信息的目的返回一个使用了适当的 CORS headers 的 `200` 或 `400` 响应。

### 简单请求 { #simple-requests }

任何带有 `Origin` 请求头的请求。在这种情况下，中间件将像平常一样传递请求，但是在响应中包含适当的 CORS headers。

Solía decir que no me gustaba mucho la historia... y mírame ahora dando lecciones de "historia tecnológica". 😅

## 타입 선언 { #declaring-types }

방금 타입 힌트를 선언하는 주요 위치를 보았습니다. 함수 매개변수입니다.

이것은 **FastAPI**와 함께 사용할 때도 주요 위치입니다.

### Simple 타입 { #simple-types }

`str`뿐 아니라 모든 파이썬 표준 타입을 선언할 수 있습니다.

예를 들어 다음을 사용할 수 있습니다:

* `int`
* `float`
* `bool`
* `bytes`
