鸿蒙金融理财全栈项目安全合规与用户体验优化

2.2 权限管理

封装权限检查与请求逻辑。

entry/src/main/ets/utils/PermissionManagementUtil.ets

import permissions from '@ohos.permissions';

export class PermissionManagementUtil {
  private static instance: PermissionManagementUtil | null = null;
  private permissionsHelper: permissions.PermissionsHelper | null = null;

  static getInstance(): PermissionManagementUtil {
    if (!PermissionManagementUtil.instance) {
      PermissionManagementUtil.instance = new PermissionManagementUtil();
    }
    return PermissionManagementUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.permissionsHelper) {
      this.permissionsHelper = permissions.createPermissionsHelper();
    }
  }

  async checkPermissions(): Promise<permissions.PermissionCheckResult> {
    if (!this.permissionsHelper) return null;
    const result = await this.permissionsHelper.checkPermissions();
    return result;
  }

  async requestPermissions(): Promise<permissions.PermissionRequestResult> {
    if (!this.permissionsHelper) return null;
    const result = await this.permissionsHelper.requestPermissions();
    return result;
  }
}

2.3 安全审计

记录关键操作日志。

entry/src/main/ets/utils/SecurityAuditUtil.ets

import audit from '@ohos.audit';

export class SecurityAuditUtil {
  private static instance: SecurityAuditUtil | null = null;
  private auditHelper: audit.AuditHelper | null = null;

  static getInstance(): SecurityAuditUtil {
    if (!SecurityAuditUtil.instance) {
      SecurityAuditUtil.instance = new SecurityAuditUtil();
    }
    return SecurityAuditUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.auditHelper) {
      this.auditHelper = audit.createAuditHelper();
    }
  }

  async auditUserOperation(logData: audit.OperationLogData): Promise<audit.SecurityAuditResult> {
    if (!this.auditHelper) return null;
    const result = await this.auditHelper.auditUserOperation(logData);
    return result;
  }
}

三、用户体验优化实现

3.1 界面优化

优化应用界面设计，提升视觉体验。

entry/src/main/ets/utils/UIOptimizationUtil.ets

import ui from '@ohos.ui';

export class UIOptimizationUtil {
  private static instance: UIOptimizationUtil | null = null;
  private uiHelper: ui.UIHelper | null = null;

  static getInstance(): UIOptimizationUtil {
    if (!UIOptimizationUtil.instance) {
      UIOptimizationUtil.instance = new UIOptimizationUtil();
    }
    return UIOptimizationUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.uiHelper) {
      this.uiHelper = ui.createUIHelper();
    }
  }

  async optimizeUIDesign(): Promise<ui.UIOptimizationResult> {
    if (!this.uiHelper) return null;
    const result = await this.uiHelper.optimizeUIDesign();
    return result;
  }
}

3.2 交互与性能优化

优化交互体验与应用性能。

entry/src/main/ets/utils/InteractionOptimizationUtil.ets

import interaction from '@ohos.interaction';

export class InteractionOptimizationUtil {
  private static instance: InteractionOptimizationUtil | null = null;
  private interactionHelper: interaction.InteractionHelper | null = null;

  static getInstance(): InteractionOptimizationUtil {
    if (!InteractionOptimizationUtil.instance) {
      InteractionOptimizationUtil.instance = new InteractionOptimizationUtil();
    }
    return InteractionOptimizationUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.interactionHelper) {
      this.interactionHelper = interaction.createInteractionHelper();
    }
  }

  async optimizeInteraction(): Promise<interaction.InteractionOptimizationResult> {
    if (!this.interactionHelper) return null;
    const result = await this.interactionHelper.optimizeInteraction();
    return result;
  }
}

entry/src/main/ets/utils/PerformanceOptimizationUtil.ets

import optimization from '@ohos.optimization';

export class PerformanceOptimizationUtil {
  private static instance: PerformanceOptimizationUtil | null = null;
  private optimizationHelper: optimization.OptimizationHelper | null = null;

  static getInstance(): PerformanceOptimizationUtil {
    if (!PerformanceOptimizationUtil.instance) {
      PerformanceOptimizationUtil.instance = new PerformanceOptimizationUtil();
    }
    return PerformanceOptimizationUtil.instance;
  }

  async init(): Promise<void> {
    if (!this.optimizationHelper) {
      this.optimizationHelper = optimization.createOptimizationHelper();
    }
  }

  async optimizePerformance(): Promise<optimization.PerformanceOptimizationResult> {
    if (!this.optimizationHelper) return null;
    const result = await this.optimizationHelper.optimizePerformance();
    return result;
  }
}

四、项目配置与部署

4.1 配置文件修改

在 entry/src/main/module.json5 中添加安全相关权限配置：

{
  "module": {
    "requestPermissions": [
      { "name": "ohos.permission.READ_USER_DATA" },
      { "name": "ohos.permission.WRITE_USER_DATA" }
    ]
  }
}

4.2 编译与测试

1. 在 DevEco Studio 中点击 Build → Build HAP 编译项目。
2. 将编译后的 HAP 文件部署到鸿蒙设备。
3. 验证数据加密、权限管理、安全审计及界面交互效果。
