HarmonyOS鸿蒙Next中从后端请求到的视音频地址，含有中文名字的展示不出来，用encodeURI编码也不行，是不是有其它方法可以解决

A页面消息发送后，B页面接收消息。此时您还在A页面。当您路由到B页面 message会重新赋值Hello World （ @State message: string = 'Hello World';）。

如果作用域的问题，可以通过const that = this解决

PageA.ets

import { router } from '@kit.ArkUI';
import { LiveEventBus } from '@ohos/liveeventbus';
@Component
struct PageA {
  build() {
    Scroll() {
      Column() {
        Button('跳转B页面3s后发送消息').margin({ bottom: '10vp' }).onClick(() => {
          setTimeout(()=>{
            LiveEventBus.get<string>("aaa").post("lalala");
          },3000)
          router.pushUrl({
            url: 'pages/PageB'
          })
        })
      }
    }
  }
}

PageB.ets

import { LiveEventBus, Lifecycle, MState } from '@ohos/liveeventbus';
import { router } from '@kit.ArkUI';
@Component
struct PageB {
  @State message: string = 'Hello World';
  @StorageLink('aaa') msg: string = '';
  observeFlag: boolean = false;
  mLifecycle: Lifecycle = new Lifecycle(MState.STARTED);
  aboutToAppear() {
    //创建生命周期感知对象
    this.mLifecycle = new Lifecycle(MState.STARTED)
    //订阅消息
   //如果作用域的问题，可以通过const that = this解决
    const that = this
    LiveEventBus
      .get<string>('aaa')
      .observe(this, {
        onChanged(s: string) {
          that.message = s
          // AppStorage.setOrCreate('aaa', s)
        }
      });
  }
  build() {
    Column() {
      Text(this.message)
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
        .onClick(() => {
          router.back()
        })
      Text(this.msg)
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
        .onClick(() => {
          router.back()
        })
      Button('手动修改').onClick(() => {
        this.message = "手动修改"
      })
      Button('发送消息').onClick(() => {
        LiveEventBus.get<string>("aaa").post("lalala2222");
      })
    }
    .height('100%')
    .width('100%')
  }
  //生命周期感知对象
  getLifecycle(): Lifecycle {
    return this.mLifecycle
  }
}
