使用枚举的Angular 8中基于角色的用户

enum Role {
  Admin = 'Admin',
  User = 'User',
  Guest = 'Guest'
}

interface User {
  name: string;
  role: Role;
}

const adminUser: User = {
  name: 'Admin User',
  role: Role.Admin
};

const regularUser: User = {
  name: 'Regular User',
  role: Role.User
};

function performAction(user: User) {
  switch (user.role) {
    case Role.Admin:
      console.log('Performing admin action...');
      // 执行管理员操作的代码
      break;
    case Role.User:
      console.log('Performing user action...');
      // 执行普通用户操作的代码
      break;
    case Role.Guest:
      console.log('Performing guest action...');
      // 执行访客操作的代码
      break;
    default:
      console.log('Unknown role');
  }
}

performAction(adminUser); // 输出：Performing admin action...
performAction(regularUser); // 输出：Performing user action...
