2. 基础广告集成

2.1 初始化Ads Kit

// ads-init.ets
import { Ads } from '@ohos.ads';

export const initAds = () => {
  Ads.init({
    appId: 'YOUR_APP_ID',
    config: {
      testMode: process.env.NODE_ENV === 'development',
      personalized: true // 启用个性化推荐
    }
  });
  
  // 设置用户数据（需获得授权）
  Ads.setUserProfile({
    age: getUserAge(),
    interests: ['sports', 'technology']
  });
};

2.2 加载横幅广告

// banner-ad.ets
@Component
struct BannerAd {
  @State adLoaded: boolean = false;

  build() {
    Column() {
      if (this.adLoaded) {
        AdComponent({
          adUnitId: 'banner_default',
          style: {
            width: '100%',
            height: '90vp'
          },
          onAdLoaded: () => {
            this.adLoaded = true;
            logRevenue('banner');
          }
        })
      } else {
        LoadingIndicator()
      }
    }
    .onAppear(() => this.loadAd())
  }

  private loadAd() {
    Ads.loadBanner({
      adUnitId: 'banner_default',
      adSize: '360 * 90'
    });
  }
}

3. 智能投放策略

3.1 动态广告源选择

// ad-strategy.ets
import { AdSourceSelector } from '@ohos.ads.strategy';

export class SmartAdManager {
  private selector = new AdSourceSelector();
  
  async getOptimalAd(adType: string) {
    const sources = await this.selector.evaluate({
      type: adType,
      criteria: {
        ecpmThreshold: 0.5, // 最低eCPM阈值
        fillRate: 0.95,      // 填充率要求
        deviceType: DeviceInfo.type
      }
    });
    
    return sources[0]; // 返回最佳广告源
  }
}

3.2 实时竞价优化

// ad-bidding.ets
export async function fetchBidResponse(adUnit: string) {
  const bidRequest = {
    adUnitId: adUnit,
    adSizes: ['360 * 90', '480 * 120'],
    bidFloor: 0.1 // 底价(美元)
  };
  
  const responses = await Promise.all([
    Ads.requestBid('huawei', bidRequest),
    Ads.requestBid('admob', bidRequest),
    Ads.requestBid('unity', bidRequest)
  ]);
  
  return responses.sort((a, b) => b.price - a.price)[0];
}

4. 个性化渲染优化

4.1 动态广告样式

// dynamic-ad.ets
@Component
struct DynamicAd {
  @Prop adData: AdData;
  @State renderStyle: AdStyle = getDefaultStyle();

  aboutToAppear() {
    this.analyzeUserPreference();
  }

  async analyzeUserPreference() {
    const pref = await UserBehaviorAnalyzer.getAdPreference();
    this.renderStyle = {
      bgColor: pref.darkMode ? '#333' : '#FFF',
      textSize: pref.fontScale > 1 ? '18fp' : '14fp',
      animation: pref.likeAnimation ? 'fadeIn' : 'none'
    };
  }

  build() {
    AdComponent({
      adUnitId: this.adData.unitId,
      style: this.renderStyle,
      interactive: true
    })
  }
}

4.2 场景化广告位

// contextual-ad.ets
export function getContextualAd(context: PageContext) {
  const mapping = {
    'sports': 'ad_sports_highvalue',
    'news': 'ad_news_video',
    'music': 'ad_music_audio'
  };
  
  return mapping[context] || 'default_ad';
}

5. 收益分析系统

5.1 实时收益追踪

// revenue-tracker.ets
import { Analytics } from '@ohos.ads.analytics';

export function logRevenue(adType: string) {
  Analytics.track('ad_revenue', {
    ad_type: adType,
    timestamp: new Date().getTime(),
    currency: 'USD',
    value: getAdValue(adType)
  });
}

function getAdValue(type: string): number {
  const values = {
    banner: 0.02,
    interstitial: 0.15,
    rewarded: 0.30
  };
  return values[type] || 0;
}

5.2 自动策略调整

// auto-optimizer.ets
export class AdOptimizer {
  private history: AdPerformance[] = [];
  
  async optimize() {
    const report = await Ads.getDailyReport();
    this.history.push(report);
    
    if (report.ecpm < 0.5) {
      this.switchToHigherValueAd();
    }
    
    if (report.fillRate < 0.7) {
      this.addFallbackNetwork();
    }
  }
  
  private switchToHigherValueAd() {
    Ads.updateConfig({
      preferredAdTypes: ['video', 'interstitial']
    });
  }
}

6. 高级功能集成

6.1 激励视频广告

// rewarded-ad.ets
@Component
struct RewardedAdButton {
  @State ready: boolean = false;

  build() {
    Button('领取奖励')
      .enabled(this.ready)
      .onClick(() => this.showAd())
      .onAppear(() => this.preload())
  }

  private preload() {
    Ads.preloadRewarded({
      adUnitId: 'rewarded_default',
      onReady: () => this.ready = true
    });
  }

  private showAd() {
    Ads.showRewarded({
      adUnitId: 'rewarded_default',
      rewardCallback: (type, amount) => {
        giveUserReward(type, amount);
      }
    });
  }
}

6.2 原生广告定制

// native-ad.ets
@Component
struct CustomNativeAd {
  @Link adData: NativeAdData;

  build() {
    Column() {
      Image(this.adData.images[0])
        .width('100%')
        .aspectRatio(1.78)
      
      Text(this.adData.title)
        .fontSize(16)
        .fontColor('#333')
      
      Button(this.adData.callToAction)
        .onClick(() => this.adData.recordClick())
    }
    .borderRadius(8)
    .backgroundColor('#FFF')
  }
}

      this.stats = data;
    });
  }

  build() {
    Grid() {
      GridItem() {
        RevenueChart(this.stats)
      }
      GridItem() {
        PerformanceMetric({
