参考示例代码：

import Base from '@ohos.base';
import CommonEventManager from '@ohos.commonEventManager';
import WantAgent, { WantAgent as _WantAgent } from '@ohos.app.ability.wantAgent';
import Want from '@ohos.app.ability.Want';
import { notificationManager } from '@kit.NotificationKit';
import { hilog } from '@kit.PerformanceAnalysisKit';

export const LOG_TAG = 'subscriber'

@Entry
@Component
struct Index {
  aboutToAppear(): void {
    notificationManager.requestEnableNotification();
  }

  build() {
    Row() {
      Column() {
        Text('订阅方')
          .fontSize(30)
          .fontWeight(500)
        Button('订阅公共事件')
          .fontSize(16)
          .fontWeight(500)
          .padding(15)
          .margin(10)
          .width('300')
          .height('60')
          .onClick(() => {
            //创建订阅者
            try {
              CommonEventManager.createSubscriber(subscribeInfo, createCB);
            } catch (error) {
              let err: Base.BusinessError = error as Base.BusinessError;
              hilog.error(0xFF00, LOG_TAG, `createSubscriber failed, code is ${err.code}, message is ${err.message}`);
            }
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}

let subscriber: CommonEventManager.CommonEventSubscriber; //用于保存创建成功的订阅者对象，后续使用其完成订阅及退订的动作
//订阅者信息

    hilog.info(0xFF00, LOG_TAG, 'createSubscriber');
    subscriber = commonEventSubscriber;
    //订阅公共事件
    try {
      CommonEventManager.subscribe(subscriber, SubscribeCB);
    } catch (error) {
      let err: Base.BusinessError = error as Base.BusinessError;
      hilog.error(0xFF00, LOG_TAG, `subscribe failed, code is ${err.code}, message is ${err.message}`);
    }
  } else {
    hilog.error(0xFF00, LOG_TAG, `createSubscriber failed, code is ${err.code}, message is ${err.message}`);
  }
}
