鸿蒙~线程间通信

• 使用Emitter进行线程间通信

import emitter from "@ohos.events.emitter";

let event = {
  eventId : 1
}

let event11 = {
  eventId: 1,
  priority: emitter.EventPriority.LOW
};

let eventData = {
  data: {
    "content": "c",
    "id": 1,
    "isEmpty": false,
  }
};

@Entry
@Component
struct Index {
  @State text: string = "";
  @State publish: string = "";

  onPageShow() {
 // 订阅事件
    emitter.on(event, (eventData) => {
       console.info("huxiubo", `eventData :${JSON.stringify(eventData)}`);
    })
  }

// 发送事件
  publishEmitter() {
    emitter.emit(event, eventData)
  }

  build() {
    Column({ space: 10 }) {


      Button("发布公共事件")
        .size({ width: 260, height: 50 })
        .onClick(() => {
          this.publishEmitter();
        })



    }
    .padding(10)
    .size({ width: "100%", height: '100%' })
  }
}

• 使用Worker进行线程间通信
