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

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")
