双12用户权限管理选购

class User:
    def __init__(self, name, role):
        self.name = name
        self.role = role

class Role:
    def __init__(self, name, permissions):
        self.name = name
        self.permissions = permissions

# 定义角色和权限
admin_role = Role('admin', ['create', 'read', 'update', 'delete'])
user_role = Role('user', ['read'])

# 创建用户并分配角色
users = [
    User('Alice', admin_role),
    User('Bob', user_role)
]

# 检查权限
def check_permission(user, action):
    if action in user.role.permissions:
        print(f"{user.name} has permission to {action}.")
    else:
        print(f"{user.name} does not have permission to {action}.")

# 测试
check_permission(users[0], 'create')  # Alice has permission to create.
check_permission(users[1], 'create')  # Bob does not have permission to create.
