Python Go的开源访问控制库Casbin
以下是一个基于Python实现的简单RBAC1访问决策控制继承关系代码示例:
```python
class Role:
def __init__(self, name, permissions):
self.name = name
self.permissions = permissions
class User:
def __init__(self, name, role):
self.name = name
self.role = role
class RBAC:
def __init__(self):
self.roles = []
self.users = []
def add_role(self, role):
self.roles.append(role)
def add_user(self, user):
self.users.append(user)
def can_access(self, user, resource):
if user.role.permissions.get(resource):
return True
else:
return False
# Example usage
rbac = RBAC()
# Define roles and their permissions
admin_role = Role('Admin', {'read': True, 'write': True, 'execute': True})
guest_role = Role('Guest', {'read': True, 'write': False, 'execute': False})
# Add roles to RBAC system
rbac.add_role(admin_role)
rbac.add_role(guest_role)
# Define users and their roles
admin_user = User('AdminUser', admin_role)
guest_user = User('GuestUser', guest_role)
# Add users to RBAC system
rbac.add_user(admin_user)
rbac.add_user(guest_user)
# Test access control
print(rbac.can_access(admin_user, 'read'))
print(rbac.can_access(guest_user, 'write'))
```
在这个示例中,我们定义了两个角色(管理员和访客),并为每个角色定义了一些权限。我们还定义了两个用户(管理员用户和访客用户),并为每个用户指定了一个角色。最后,我们测试了访问控制系统,以确保只有具有相应权限的用户才能访问特定资源。
