* `users:read` oder `users:write` sind gängige Beispiele.
* `instagram_basic` wird von Facebook / Instagram verwendet.
* `https://www.googleapis.com/auth/drive` wird von Google verwendet.

/// info | Info

In OAuth2 ist ein „Scope“ nur ein String, der eine bestimmte erforderliche Berechtigung deklariert.

각 "범위"는 공백이 없는 문자열입니다.

일반적으로 특정 보안 권한을 선언하는 데 사용됩니다. 다음을 봅시다:

* `users:read` 또는 `users:write`는 일반적인 예시입니다.
* `instagram_basic`은 페이스북/인스타그램에서 사용합니다.
* `https://www.googleapis.com/auth/drive`는 Google에서 사용합니다.

/// info | 정보

OAuth2에서 "범위"는 필요한 특정 권한을 선언하는 문자열입니다.

`:`과 같은 다른 문자가 있는지 또는 URL인지는 중요하지 않습니다.

이러한 세부 사항은 구현에 따라 다릅니다.

OAuth2의 경우 문자열일 뿐입니다.
