모델(model) 및 정책(policy) 선언 파일로부터 Enforcer를 생성합니다.

import "github.com/casbin/casbin/v2"

e, err := casbin.NewEnforcer("path/to/model.conf", "path/to/policy.csv")

import org.casbin.jcasbin.main.Enforcer;

tip

파일 대신, DB에서 정책을 불러와서 Enforcer를 초기화할 수도 있습니다. 자세한 내용은 Adapters 를 참조하세요.

Casbin은 실행 시간에 권한 허용 여부를 관리하기 위한 API를 제공합니다. 예를 들어, 아래와 같이 사용자에게 할당된 역할(Role) 을 조회할 수 있습니다.

Java

Node.js

PHP

Python

Delphi

Rust

roles := e.GetRolesForUser("alice")

Roles roles = e.getRolesForUser("alice");

const roles = await e.getRolesForUser('alice');

$roles = $e->getRolesForUser("alice");

roles = e.get_roles_for_user("alice")

```rust
let roles = e.get_roles_for_user("alice");
