HarmonyOS router.getParams()按示例代码，无法取值

页面1通过router.pushUrl，将一个Class作为参数传递给页面2

页面2通过router.getParams()获取后，变量有值，但是类中属性获取时为undefined

参考demo如下:

import router from '@ohos.router'; 
class innerParams { 
  array:number[] 
  constructor(tuple:number[]) { 
    this.array = tuple 
  } 
} 
 
class routerParams { 
  text:string 
  data:innerParams 
  constructor(str:string, tuple:number[]) { 
    this.text = str 
    this.data = new innerParams(tuple) 
  } 
} 
 
@Entry 
@Component 
struct Router1 { 
 
  build() { 
 
    Column(){ 
      Column(){ 
        Text("我是页面1").fontSize(50) 
      } 
      Column(){ 
 
        Button("跳转") 
          .onClick(()=>{ 
            router.pushUrl({ 
              url: 'pages/Router11', 
              params: new routerParams('message' ,[123,456,789]) 
            }) 
          }) 
      } 
    } 
    .width('100%') 
    .height('100%') 
  } 
} 
import router from '@ohos.router'; 
 
class innerParams { 
  array:number[] 
 
  constructor(tuple:number[]) { 
    this.array = tuple 
  } 
} 
 
class routerParams { 
  text:string 
  data:innerParams 
  constructor(str:string, tuple:number[]) { 
    this.text = str 
    this.data = new innerParams(tuple) 
  } 
} 
@Entry 
@Component 
struct Router11 { 
 
  aboutToAppear(): void { 
    let s:number[]=((router.getParams() as routerParams).data as innerParams).array 
    console.log("*********:"+s); 
  } 
  build() { 
    Column(){ 
      Text("123").fontSize(50) 
      Row(){ 
        Text("33333").fontSize(50) 
      } 
    } 
    .width('100%') 
    .height('100%') 
    .opacity(0.5) 
    .backgroundColor(Color.Pink) 
 
  }
