// 页面使用

import 'reflect-metadata' 
 
@Observed 
class User { 
  name: string = '' 
  isClick: boolean = false 
} 
 
class UserObj { 
  @Type (() => User) 
  user: User = new User(); 
} 
 
@ObjectLink user:User 
 
let responseData : Record<string, ESObject> = { 
  "user" : { 
    "name" : 'xxx', 
    "isClick": false, 
  } 
} 
let user = plainToClass(UserObj, responseData).user;
