그러면 브라우저에서 `http://localhost:8080`으로 실행되는 프론트엔드가 있고, 그 JavaScript가 `http://localhost`에서 실행되는 백엔드와 통신하려고 한다고 해봅시다(포트를 명시하지 않았기 때문에, 브라우저는 기본 포트 `80`을 가정합니다).

그러면 브라우저는 `:80`-백엔드에 HTTP `OPTIONS` 요청을 보내고, 백엔드가 이 다른 출처(`http://localhost:8080`)로부터의 통신을 허가하는 적절한 헤더를 보내면, `:8080`-브라우저는 프론트엔드의 JavaScript가 `:80`-백엔드에 요청을 보낼 수 있도록 합니다.

이를 위해, `:80`-백엔드는 "허용된 출처(allowed origins)" 목록을 가지고 있어야 합니다.

        Add a *path operation* using an HTTP OPTIONS operation.

        ## Example

        ```python
        from fastapi import FastAPI

        app = FastAPI()

        @app.options("/items/")
        def get_item_options():
            return {"additions": ["Aji", "Guacamole"]}
        ```
        """
        return self.router.options(
            path,

`http://localhost:8080`, e seu JavaScript esteja tentando se comunicar com um backend rodando em `http://localhost` (como não especificamos uma porta, o navegador assumirá a porta padrão `80`).

Portanto, o navegador enviará uma requisição HTTP `OPTIONS` ao backend `:80`, e se o backend enviar os cabeçalhos apropriados autorizando a comunicação a partir dessa origem diferente (`http://localhost:8080`), então o navegador `:8080` permitirá que o JavaScript no frontend envie sua requisição para o backend...
