여기에서 다음을 설정할 수 있습니다:

* 경로에 사용된 "Item ID".
* 쿼리 매개변수로 사용된 "Token".

/// tip | 팁

쿼리 `token`은 종속성에 의해 처리됩니다.

이렇게 하면 WebSocket에 연결하고 메시지를 전송 및 수신할 수 있습니다:

* Configure any required permissions and roles using dependencies.
* Never store plaintext passwords, only password hashes.
* Implement and use well-known cryptographic tools, like pwdlib and JWT tokens, etc.
* Add more granular permission controls with OAuth2 scopes where needed.
* ...etc.
