下面是一个复杂的json体。

怎么把json转实体类，首先要定义类

import List from '@ohos.util.List'
export class InfoModel{
  msg: string
  cars: List<Cars>
  code: number
  permissions: List<string>
  roles: List<string>
  user: User
 
}
 
class Cars{
  createBy: string
  createTime: string
  updateBy: any
  car: Car
}
 
class Car{
  createBy: string
  createTime: string
  updateBy: any
}
 
class User{
  createBy: string
  createTime: string
  updateBy: string
  params: Params
  roles: List<Roles>
}
 
class Params{
  '@type': string
}
 
class Roles{
  createBy: any
  createTime: any
  updateBy: any
  params: Params
  permissions: List<string>
}

 实现转实体

@State info:InfoModle=new InfoModle();
this.info=JSON.parse(这里是你的json) as InfoModle;
