HarmonyOS鸿蒙Next中ESObject问题咨询

可以使用Record键值对来解析、传递参数

看下这两段代码：

第一段：

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  // @State param: object|null = null
  @State param: Record<string, string> = {}

  private getParams(): ESObject {
    return {
      "eventVersion": "5.2.26",
      "schoolId": "0",
      "roleType": "1",
      "eventDeviceType": "android"
    };
  }

  build() {
    Column({ space: 10 }) {
      Button("点击").onClick(() => {
        // promptAction.showToast({message: JSON.stringify(this.getParams())})
        this.param = this.getParams() as Record<string, string>;
      })
      Text(`${this.param?.eventVersion}`)
      Text(`${this.param?.schoolId}`)
      Text(`${this.param?.roleType}`)
      Text(`${this.param?.eventDeviceType}`)
      Text(`${JSON.stringify(this.param)}`)
    }
    .width('100%')
    .height('100%')
    .justifyContent(FlexAlign.Center)
  }
}

第二段：

import { promptAction } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  @State param: Record<string, string> = {};

  aboutToAppear(): void {
    this.param['key1'] = 'value1'
  }

  build() {
    Column() {
      Button("获取参数").onClick(() => {
        if (this.param) {
          promptAction.showToast({ message: `${JSON.stringify(this.param['key1'])}` })
        }
      })
    }
    .width("100%")
    .height("100%")
    .justifyContent(FlexAlign.Center)
  }
}
