HarmonyOS 5统一身份认证海外适配方案

以下为 ​​HarmonyOS 5统一身份认证海外适配的完整解决方案​​，包含多区域合规、协议转换和全球化部署的代码实现：

---

1. 系统架构

---

2. 核心认证模块

2.1 多协议认证适配

// auth-adapter.ets
import { OAuth2, SAML, OpenID } from '@ohos.security.auth';

class GlobalAuthAdapter {
  private static providers = new Map<string, AuthProvider>();

  static async authenticate(region: string, credentials: Credentials): Promise<AuthResult> {
    const provider = this._getProvider(region);
    return provider.authenticate(credentials);
  }

  private static _getProvider(region: string): AuthProvider {
    if (!this.providers.has(region)) {
      this.providers.set(region, this._createProvider(region));
    }
    return this.providers.get(region)!;
  }

  private static _createProvider(region: string): AuthProvider {
    switch (region) {
      case 'EU': return new OAuth2(this._getEUConfig());
      case 'US': return new SAML(this._getUSConfig());
      case 'BR': return new OpenID(this._getBRConfig());
      default: return new OAuth2(this._getGlobalConfig());
    }
  }
}

2.2 合规数据脱敏

// data-masker.ets
class ComplianceMasker {
  static maskPersonalData(data: UserData): UserData {
    return {
      ...data,
      email: this._maskEmail(data.email),
      phone: this._maskPhone(data.phone),
      location: this._generalizeLocation(data.location)
    };
  }

  private static _maskEmail(email: string): string {
    return email.replace(/(.).+@(.+)/, '$1***@$2');
  }

  private static _maskPhone(phone: string): string {
    return phone.replace(/\d(?=\d{4})/g, '*');
  }
}

---

3. 区域化实现

3.1 GDPR合规处理

// gdpr-processor.ets
class GDPRProcessor {
  static async processConsent(userId: string): Promise<void> {
    const consent = await ConsentManager.get(userId);
    if (!consent.dataProcessing) {
      throw new Error('GDPR consent required');
    }

    DataSubjectAccessRequest.register(userId, {
      rightToBeForgotten: this._createDeletionHandler(userId),
      dataPortability: this._createExportHandler(userId)
    });
  }

  private static _createDeletionHandler(userId: string): () => Promise<void> {
    return async () => {
      await UserDataStore.erase(userId);
      await GlobalAuthGraph.disconnectAllSessions(userId);
    };
  }
}

3.2 CCPA用户权利

// ccpa-processor.ets
class CCPAProcessor {
  static async handleRequest(request: CCPARequest): Promise<void> {
    switch (request.type) {
      case 'DO_NOT_SELL':
        await PreferenceManager.set(userId, 'data_sale_opt_out', true);
        break;
      case 'KNOW_REQUEST':
        return this._generateDataReport(request.userId);
    }
  }

  private static async _generateDataReport(userId: string): Promise<DataReport> {
    return {
      collectedData: await DataInventory.query(userId),
      thirdParties: await DataSharing.listRecipients(userId),
      saleOptOut: await PreferenceManager.get(userId, 'data_sale_opt_out')
    };
  }
}

---

4. 全球化部署

4.1 区域路由策略

// geo-router.ets
class GeoRouter {
  private static readonly REGION_ENDPOINTS = {
    EU: 'https://auth.eu.harmonyos.com',
    US: 'https://auth.us.harmonyos.com',
    AP: 'https://auth.ap.harmonyos.com'
  };

  static getAuthEndpoint(ip: string): string {
    const region = this._detectRegion(ip);
    return this.REGION_ENDPOINTS[region] || this.REGION_ENDPOINTS.AP;
  }

  private static _detectRegion(ip: string): string {
    const geoData = IPGeoLookup.lookup(ip);
    if (geoData.countryCode.startsWith('EU')) return 'EU';
    if (['US', 'CA'].includes(geoData.countryCode)) return 'US';
    return 'AP';
  }
}

4.2 本地化存储策略

// storage-strategy.ets
class RegionalStorage {
  static async save(userId: string, data: UserData): Promise<void> {
    const region = await this._getUserRegion(userId);
    const storage = this._getStorageForRegion(region);
    await storage.save(userId, ComplianceMasker.maskPersonalData(data));
  }

  private static _getStorageForRegion(region: string): StorageAdapter {
    switch (region) {
      case 'EU': return new EUStorage();
      case 'US': return new S3Storage();
      default: return new GlobalCDNStorage();
    }
  }
}

5. 统一身份图谱

5.1 身份解析器

// identity-resolver.ets
class GlobalIdentityResolver {
  static async resolve(identity: UserIdentity): Promise<UnifiedUser> {
    const fragments = await Promise.all([
      this._queryLocalRegistry(identity),
      this._querySocialConnections(identity),
      this._queryEnterpriseDirectory(identity)
    ]);

    return this._mergeIdentityFragments(fragments);
  }

  private static _mergeIdentityFragments(fragments: IdentityFragment[]): UnifiedUser {
    return {
      coreIdentity: fragments[0],
      socialConnections: fragments[1],
      enterpriseAttributes: fragments[2]
    };
  }
}

5.2 跨区会话同步

// session-sync.ets
class GlobalSessionSync {
  private static readonly SYNC_INTERVAL = 30 * 1000; // 30秒

  static startSync(userId: string): void {
    setInterval(async () => {
      const sessions = await SessionManager.getAllSessions(userId);
      await distributedData.sync({
        key: `user_sessions_${userId}`,
        value: sessions,
        devices: 'all'
      });
    }, this.SYNC_INTERVAL);
  }
}

6. 安全与合规

6.1 数据加密策略

// regional-crypto.ets
class RegionalCrypto {
  private static readonly REGIONAL_ALGORITHMS = {
    EU: { alg: 'AES-256-GCM', keySize: 256 },
    US: { alg: 'AES-256-CBC', keySize: 256 },
    CN: { alg: 'SM4', keySize: 128 }
  };

  static async encrypt(region: string, data: string): Promise<string> {
    const { alg, keySize } = this.REGIONAL_ALGORITHMS[region];
    return crypto.encrypt({
      data,
      alg,
      keySize,
      key: await this._getRegionalKey(region)
    });
  }
}

6.2 审计日志

// compliance-audit.ets
class ComplianceAudit {
  static logAccess(userId: string, accessType: string): void {
    AuditLogger.log({
      event: 'DATA_ACCESS',
      userId,
      accessType,
      timestamp: Date.now(),
      region: GeoRouter.getCurrentRegion(),
      legalBasis: this._getLegalBasis(accessType)
    });
  }

  private static _getLegalBasis(accessType: string): string {
    const LEGAL_BASES = {
      'PROFILE_READ': 'Consent',
      'PAYMENT_UPDATE': 'Contractual Necessity'
    };
    return LEGAL_BASES[accessType] || 'Legitimate Interest';
  }
}

7. 完整认证流程

7.1 用户注册

// registration.ets
@Component
struct GlobalRegistration {
  @State region?: string;

  build() {
    Column() {
      RegionSelector(onSelect: (r) => this.region = r)
      if (this.region) {
        AuthForm(region: this.region)
      }
    }
  }
}

7.2 多因素认证

// mfa-handler.ets
class RegionalMFAHandler {
  static async verify(userId: string, factor: AuthFactor): Promise<boolean> {
    const region = await GeoRouter.getUserRegion(userId);
    switch (region) {
      case 'EU':
        return this._verifyWithGDPR(userId, factor);
      case 'US':
        return this._verifyWithCCPA(userId, factor);
      default:
        return this._verifyGlobal(userId, factor);
    }
  }
}

8. 部署配置

8.1 区域化配置

// region-config.json
{
  "EU": {
    "requiredConsents": ["data_processing", "cookies"],
    "minAge": 16,
    "defaultLanguage": "en"
  },
  "US": {
    "requiredConsents": ["data_sale_opt_out"],
    "minAge": 13,
    "defaultLanguage": "en"
  },
  "JP": {
    "requiredConsents": ["specific_purpose"],
    "minAge": 20,
    "defaultLanguage": "ja"
  }
}

8.2 安全策略

// security-policy.ets
class RegionalSecurityPolicy {
  static getPasswordPolicy(region: string): PasswordPolicy {
    const POLICIES = {
      EU: { minLength: 12, complexity: 4 },
      US: { minLength: 8, complexity: 3 },
      AP: { minLength: 10, complexity: 3 }
    };
    return POLICIES[region] || POLICIES.AP;
  }
}
