Mas isso só permitirá certos tipos de comunicação, excluindo tudo que envolva credenciais: cookies, cabeçalhos de autorização como aqueles usados ​​com Bearer Tokens, etc.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

이 경우, `:8080`-프론트엔드가 올바르게 동작하려면 목록에 `http://localhost:8080`이 포함되어야 합니다.

## 와일드카드 { #wildcards }

또한 목록을 `"*"`("와일드카드")로 선언해 모두 허용된다고 말할 수도 있습니다.

하지만 그러면 자격 증명(credentials)이 포함된 모든 것을 제외하고 특정 유형의 통신만 허용하게 됩니다. 예: 쿠키, Bearer Token에 사용되는 것과 같은 Authorization 헤더 등.

따라서 모든 것이 올바르게 동작하게 하려면, 허용된 출처를 명시적으로 지정하는 것이 더 좋습니다.
