基于之前建立的 Prism 模块化架构。1. 用户登录 权限系统1User 实体与服务// MaxWell.Domain/Entities/User.csnamespaceMaxWell.Domain.Entities;publicclassUser{publicstringUserId{get;set;}string.Empty;publicstringUserName{get;set;}string.Empty;publicstringDisplayName{get;set;}string.Empty;publicstringRole{get;set;}Operator;// Operator, Engineer, AdminpublicDateTimeLoginTime{get;set;}DateTime.UtcNow;publicListstringPermissions{get;set;}new();}2IUserService 接口// MaxWell.CommonBasis/Services/IUserService.csnamespaceMaxWell.CommonBasis.Services;publicinterfaceIUserService{UserCurrentUser{get;}boolIsLoggedIn{get;}eventEventHandlerUser?UserChanged;TaskLoginResultLoginAsync(stringusername,stringpassword);voidLogout();boolHasPermission(stringpermission);boolIsInRole(stringrole);}3UserService 实现// MaxWell.CommonBasis/Services/UserService.csusingMaxWell.Domain.Entities;namespaceMaxWell.CommonBasis.Services;publicclassUserService:IUserService{publicUserCurrentUser{get;privateset;}newUser{RoleGuest};publicboolIsLoggedInCurrentUser.Role!Guest;publiceventEventHandlerUser??UserChanged;privatereadonlyILog_loggerLogManager.GetLogger(UserService);publicasyncTaskLoginResultLoginAsync(stringusername,stringpassword){// 实际项目中应调用认证服务或数据库awaitTask.Delay(300);// 模拟网络延迟if(usernameadminpassword123456){CurrentUsernewUser{UserIdU001,UserNameusername,DisplayName管理员,RoleAdmin,Permissions{Experiment.Start,Vision.Control,Alarm.Manage}};}elseif(usernameengineerpassword123456){CurrentUsernewUser{UserIdU002,UserNameusername,DisplayName工程师,RoleEngineer,Permissions{Experiment.Start,Vision.View}};}else{returnLoginResult.Fail(用户名或密码错误);}UserChanged?.Invoke(this,CurrentUser);_logger.Info($用户登录成功:{CurrentUser.DisplayName}({CurrentUser.Role}));returnLoginResult.Success(CurrentUser);}publicvoidLogout(){CurrentUsernewUser{RoleGuest};UserChanged?.Invoke(this,null);_logger.Info(用户已登出);}publicboolHasPermission(stringpermission){returnCurrentUser.Permissions.Contains(permission);}publicboolIsInRole(stringrole){returnCurrentUser.Role.Equals(role,StringComparison.OrdinalIgnoreCase);}}2.

在 App.xaml.cs 中集成protectedoverridevoidRegisterTypes(IContainerRegistrycontainerRegistry){// ... 其他注册containerRegistry.RegisterSingletonModuleConfigurationManager();containerRegistry.RegisterSingletonDynamicModuleLoader();containerRegistry.RegisterSingletonIModulePermissionService,ModulePermissionService();containerRegistry.RegisterSingletonIUserService,UserService();// 注册模块管理界面containerRegistry.RegisterForNavigationModuleManagementView,ModuleManagementViewModel(ModuleManagementView);}使用方式登录后可进入“模块管理”页面支持运行时动态加载/卸载模块权限系统可控制哪些用户能操作模块
