角色配置示例 roles: super_admin: name: 超级管理员 permissions: - * # 所有权限 admin: name: 管理员 permissions: - user:manage - knowledge:manage - audit:view - config:manage department_manager: name: 部门负责人 permissions: - user:view - knowledge:manage:department - audit:view:department normal_user: name: 普通用户 permissions: - chat:use - knowledge:query - history:view:self2. 权限配置代码示例# permission_manager.py from workbuddy import PermissionManager, Role class WorkBuddyPermissionManager: def __init__(self, config_path): self.pm PermissionManager(config_path) def create_role(self, role_id, name, permissions): 创建新角色 role Role( idrole_id, namename, permissionspermissions ) return self.pm.create_role(role) def assign_role(self, user_id, role_id, scopeNone): 为用户分配角色 scope: 权限范围如 {department: 技术部} return self.pm.assign_role( user_iduser_id, role_idrole_id, scopescope ) def check_permission(self, user_id, permission, resourceNone): 检查用户是否有指定权限 return self.pm.check_permission( user_iduser_id, permissionpermission, resourceresource ) def get_user_permissions(self, user_id): 获取用户的所有权限 return self.pm.get_user_permissions(user_id) # 使用示例 pm WorkBuddyPermissionManager(/etc/workbuddy/roles.yaml) # 创建部门知识库管理员角色 pm.create_role( role_idkb_manager, name知识库管理员, permissions[ knowledge:upload, knowledge:update, knowledge:delete, knowledge:query ] ) # 为技术部张三分配知识库管理员权限仅限技术部范围 pm.assign_role( user_idzhangsancompany.com, role_idkb_manager, scope{department: 技术部} ) # 检查权限 has_permission pm.check_permission( user_idzhangsancompany.com, permissionknowledge:upload, resource{department: 技术部} # 可以 # resource{department: 财务部} # 不可以 )3. 数据隔离配置# data_isolation.py from workbuddy import DataIsolationPolicy class DataIsolationManager: 数据隔离管理器 ISOLATION_LEVELS { organization: 组织级, # 整个企业可见 department: 部门级, # 仅本部门可见 team: 团队级, # 仅本团队可见 private: 私有 # 仅自己可见 } def __init__(self): self.policy DataIsolationPolicy() def set_document_visibility(self, doc_id, level, scopeNone): 设置文档可见性 Args: doc_id: 文档ID level: 隔离级别 (organization/department/team/private) scope: 范围定义如 {departments: [技术部, 产品部]} return self.policy.set_visibility( resource_typedocument, resource_iddoc_id, levellevel, scopescope ) def can_access(self, user_id, doc_id): 检查用户是否可以访问文档 user_info self.get_user_info(user_id) doc_info self.get_document_info(doc_id) level doc_info[visibility_level] scope doc_info.get(visibility_scope, {}) if level organization: return True elif level department: allowed_depts scope.get(departments, []) return user_info[department] in allowed_depts elif level team: allowed_teams scope.get(teams, []) return user_info[team] in allowed_teams elif level private: return doc_info[owner] user_id return False # 配置示例 isolation DataIsolationManager() # 上传技术文档设置仅技术部可见 isolation.set_document_visibility( doc_idtech-spec-001, leveldepartment, scope{departments: [技术部]} )安全配置详解1. 传输层安全# security.yaml -
