HarmonyOS 接口返回的Json 如何解析成定义在 ets 文件中的类？

@Entry  
@Component  
struct JsonPage {  
  resultInfo: string = '{"state":0,"message":"ok","user":{ "id":"001","name":"zhangsan" }}'  
  
  build() {  
    Column() {  
      Text('test').onClick(() => {  
        const temp: Respon = JSON.parse(this.resultInfo);  
        console.info(temp.user.name)  
  
      })  
    }  
  }  
}  
  
class Respon {  
  state: string = ''  
  message: string = ''  
  user: User = new User();  
}  
  
class User {  
  id: string = ''  
  name: string = ''  
}
