鸿蒙智能提醒实战：Notification Kit 实现文档关键节点零遗漏

在文档全生命周期管理中，我们基于 Notification Kit 构建多维度提醒系统，核心实现代码如下：

typescript

// 1. 智能通知中心初始化

const notifyEngine = await notification.createEngine({

  channels: [

    {

      id: 'doc_alert',

      name: '文档时效提醒',

      importance: 'HIGH',

      lights: true,

      vibration: 'CUSTOM'

    },

    {

      id: 'collab_request',

      name: '协作请求',

      visibility: 'PUBLIC',

      badge: true

    }

  ],

  scheduling: {

    precision: 'EXACT',

    dozeWhitelist: true

  },

  analytics: {

    deliveryTracking: true,

    interactionLogging: true

  }

})

// 2. 合同关键节点提醒

const contractNotifier = new notification.SmartNotifier({

  triggers: [

    {

      type: 'DEADLINE',

      conditions: ['3D_BEFORE', '1H_BEFORE'],

      actions: [

        'FULL_SCREEN',

        'AUTO_CALL'

      ]

    },

    {

      type: 'SIGNATURE_PENDING',

      recipients: ['SIGNER', 'WITNESS'],

      escalation: {

        interval: '2H',

        maxLevel: 3

      }

    }

  ],

  templates: {

    legal: {

      title: '[法律时效] ${docName}',

      content: '距离${event}还剩${remain}',

      priority: 'MAX'

    }

  }

})

// 3. 多端同步通知

const syncNotifier = notification.createCrossDeviceSync({

  devices: ['PHONE', 'PAD', 'PC'],

  routing: 'SMART',

  stateSharing: true,

  interaction: {

    ackTimeout: '30M',

    followUp: 'NEXT_DEVICE'

  }

})

// 4. 情景感知优化

const contextAware = new notification.ContextOptimizer({

  factors: [

    'USER_ACTIVITY',

    'DEVICE_STATE',

    'LOCATION'

  ],

  rules: [

    {

      when: 'MEETING_MODE',

      then: { vibration: 'OFF', sound: 'DING' }

    },

    {

      when: 'DRIVING',

      then: { delivery: 'DELAYED', readAloud: true }

    }

  ]

})

// 5. 紧急通知保障

const emergencyChannel = notification.createCriticalNotifier({

  override: {

    dnd: true,

    batterySaver: true

  },

  confirmation: {

    required: true,

    methods: ['BIOMETRIC', 'PATTERN']

  },

  fallback: [

    { type: 'SMS', template: 'URGENT: ${message}' },

    { type: 'PHONE_CALL', timeout: '30S' }

  ]

})

//关键技术组件：

//智能免打扰：

typescript

notifyEngine.enableSmartDND({

  exceptions: ['LEGAL_DEADLINE', 'SECURITY_ALERT'],

  learning: 'USER_RESPONSE'

})

//富媒体通知：

typescript

notification.enableRichContent({

  documents: true,

  markdown: true,

  actions: [

    'SIGN_NOW',

    'REQUEST_EXTENSION'

  ]

})

//通知状态同步：

typescript

syncNotifier.enableBlockchainProof({

  chain: 'HYPERLEDGER',

  events: ['DELIVERY', 'READ']

})

//企业级扩展方案：

//合规审计：

typescript

notifyEngine.enableComplianceLogging({

  standards: ['FINRA', 'SOX'],

  retention: '7Y',

  watermark: 'USER+TIMESTAMP'

})

//AI优先级调度：

typescript

contractNotifier.enableAIPrioritization({

  model: 'urgency_predictor_v3',

  inputs: [

    'DOC_TYPE',

    'TIME_SENSITIVITY',

    'USER_HISTORY'

  ]

})

//多语言自动适配：

typescript

notification.setAutoTranslation({

  targetLanguage: 'SYSTEM_DEFAULT',

  supported: ['zh', 'en', 'es']

})

//优化实践建议：

//性能调优：

typescript

notifyEngine.setDeliveryPolicy({

  batchInterval: '5S',

  networkRetry: 'EXPONENTIAL'

})

//资源控制：

typescript

notification.configureResourceUsage({

  maxConcurrent: 10,

  cpuThrottle: 'AUTO'

})

典型应用场景：

合同截止期限预警

文档审批催办

法律时效提醒

紧急签署请求
