鸿蒙智能催办实战：Push Kit 实现文档流程零延迟推进

在文档审批自动化场景中，我们基于 Push Kit 构建高可靠催办系统，核心实现代码如下：

typescript

// 1. 推送服务初始化

const pushEngine = await push.createEngine({

  environment: push.Environment.ENTERPRISE,

  channels: [

    {

      id: 'doc_approval',

      priority: push.Priority.HIGH,

      delivery: push.Delivery.GUARANTEED,

      visibility: push.Visibility.PUBLIC

    },

    {

      id: 'legal_alert',

      priority: push.Priority.MAX,

      ttl: 86400,

      retry: push.Retry.EXPONENTIAL

    }

  ],

  security: {

    encryption: push.Encryption.HW_KMS,

    authentication: push.Auth.MUTUAL_TLS

  }

})

// 2. 智能流程催办

const approvalNotifier = new push.ApprovalDispatcher({

  triggers: [

    {

      condition: 'PENDING_OVER_1H',

      action: 'ESCALATE',

      targets: ['APPROVER', 'SUPERVISOR']

    },

    {

      condition: 'DEADLINE_APPROACHING',

      action: 'MULTI_CHANNEL',

      channels: ['APP', 'SMS', 'EMAIL']

    }

  ],

  templates: {

    reminder: {

      title: '[${docType}]待审批: ${docName}',

      body: '剩余时间: ${remaining}',

      urgency: 'TIME_SENSITIVE'

    }

  }

})

// 3. 跨设备状态同步

const syncManager = push.createCrossDeviceSync({

  deviceGroups: ['PHONE', 'TABLET', 'PC'],

  stateSharing: {

    readStatus: true,

    actionTaken: true

  },

  conflict: {

    resolution: 'LAST_ACTION_WINS',

    logging: 'FULL'

  }

})

// 4. 实时到达率监控

const deliveryTracker = new push.DeliveryAnalytics({

  metrics: [

    'RECEIPT_RATE',

    'OPEN_RATE',

    'RESPONSE_TIME'

  ],

  alert: {

    threshold: 0.95, // 95%到达率

    action: 'ALTERNATE_ROUTE'

  },

  reporting: {

    format: 'REALTIME_DASHBOARD',

    export: 'CSV'

  }

})

// 5. 紧急通道保障

const emergencyChannel = push.createCriticalPath({

  override: {

    batteryOptimization: true,

    dozeMode: true

  },

  fallback: [

    { type: 'VOICE_CALL', timeout: 30 },

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

  ],

  confirmation: {

    required: true,

    methods: ['BIOMETRIC', 'PATTERN']

  }

})

//关键技术组件：

//智能重试策略：

typescript

pushEngine.setRetryPolicy({

  initialInterval: 1000,

  maxInterval: 60000,

  backoffFactor: 2

})

//情景感知优化：

typescript

push.enableContextAwareDelivery({

  factors: [

    'USER_ACTIVITY',

    'DEVICE_STATE',

    'LOCATION'

  ],

  rules: [

    { when: 'MEETING', then: 'DELAY' },

    { when: 'DRIVING', then: 'READ_ALOUD' }

  ]

})

//区块链回执存证：

typescript

push.enableDeliveryProof({

  chain: 'Hyperledger',

  anchors: ['SEND_TIME', 'READ_TIME']

})

//企业级扩展方案：

//审批链穿透：

typescript

approvalNotifier.enableEscalationChain({

  levels: [

    { role: 'MANAGER', timeout: '1H' },

    { role: 'DIRECTOR', timeout: '30M' }

  ],

  finalAction: 'AUTO_APPROVE'

})

//多语言自适应：

typescript

push.setAutoTranslation({

  target: 'USER_PREFERENCE',

  supported: ['zh', 'en', 'ja']

})

//合规审计：

typescript

push.enableComplianceLogging({

  standards: ['GDPR', 'CCPA'],

  retention: '365D',

  redaction: ['PII']

})

//优化实践建议：

//性能调优：

typescript

pushEngine.setPerformanceProfile({

  queueSize: 1000,

  throughput: '5000/秒',

  latency: '<100ms'

})

//资源控制：

typescript

push.configureResourceUsage({

  maxConnections: 50,

  cpuThrottle: 0.7

})

典型应用场景：

合同审批超时催办

法律时效紧急提醒

签署环节多方通知

合规截止预警
