鸿蒙深度链接实战:App Linking Kit构建智能文档工作流

在跨应用文档协作场景中,我们基于App Linking Kit实现无缝跳转与上下文传递,核心实现代码如下:
typescript
// 1. 深度链接配置与路由注册
const docLinker = await linking.createRouter({
baseUri: 'https://doc.office/harmony',
pathConfig: {
'/view/{docId}': {
target: 'DocumentViewer',
params: {
docId: { required: true, type: 'string' },
page: { default: 1, type: 'number' },
highlight: { decoder: JSON.parse }
}
},
'/edit/{docType}': {
target: 'DocumentEditor',
authRequired: true,
context: {
carryOver: ['authToken', 'workspace']
}
}
},
fallback: {
web: 'https://web.doc.office',
appGallery: 'appgallery://detail?id=com.example.doc'
}
})
// 2. 智能链接生成
const shareLink = docLinker.generateUri({
path: '/view/doc123',
params: {
page: 5,
highlight: { text: '重要条款', color: '#FF0000' }
},
socialMeta: {
title: '请查阅合同第五条款',
description: '来自HarmonyOS文档协作系统的共享',
imageUrl: '
'
}
})
// 3. 跨应用跳转控制
linking.navigateTo(shareLink, {
transition: 'doc_shared',
referrer: await linking.getReferrer(),
onSuccess: () => logEvent('link_navigate_success'),
onFail: (err) => showErrorToast(err.message)
})
// 4. 上下文持续管理
const contextManager = new linking.ContextSession({
ttl: 3600,
storage: linking.Storage.CLOUD_DRIVEN,
encryption: {
algorithm: 'SM4',
key: await getSecureKey()
},
syncAcrossDevices: true
})
// 5. 智能路由决策
const router = new linking.SmartRouter({
deviceAware: true,
networkAware: true,
preferenceOrder: [
'LOCAL_APP',
'WEB',
'APP_GALLERY',
'ALTERNATE_APPS'
],
costMatrix: {
latency: 0.6,
dataUsage: 0.3,
batteryImpact: 0.1
}
})
//关键技术组件:
//安全验证:
typescript
linking.setAuthVerifier({
verify: async (link) => {
return await checkDocPermission(
link.params.docId,
getCurrentUser()
)
},
onReject: (link) => showPermissionDialog()
})
//深度链接分析:
typescript
linking.enableAnalytics({
trackParams: ['docType', 'source'],
conversionEvents: {
'VIEW_COMPLETE': { timer: 30 },
'EDIT_START': { immediate: true }
}
})
//离线缓存:
typescript
linking.configureOffline({
cacheTtl: 86400,
prefetch: {
enabled: true,
wifiOnly: true
}
})
//企业级扩展方案:
//B2B定制路由:
typescript
linking.registerEnterpriseRoute({
domain: 'partner.example.com',
internalOnly: true,
auth: 'CORP_SSO',
overridePaths: ['/view/confidential']
})
//区块链存证:
typescript
linking.enableBlockchainNotarization({
chain: 'Hyperledger',
events: ['SHARE', 'ACCESS'],
txBatchSize: 5
})
//动态A/B测试:
typescript
linking.setExperiment({
name: 'link_style',
variants: [
{ params: { utm: 'v1' }, weight: 0.5 },
{ params: { utm: 'v2' }, weight: 0.5 }
]
})
//优化实践建议:
//性能调优:
typescript
linking.setPerformanceProfile({
preconnect: true,
dnsPrefetch: true,
maxRedirects: 2
})
//错误恢复:
typescript
linking.setFallbackStrategy({
retries: 3,
backoff: ,
finalAction: 'COPY_CLIPBOARD'
})
