使用原生json解析时能否获取Array类型的value值?

let obj: A = 
 
  JSON.parse(’{“lictype”:“test”,“time”:“2024-06-30”,“cardtype”:[“yy”,“tt”,“rr”,“ee”,“ff”,“ww”,“ff”,“dd”,“ss”,“qq”,“ww”],“ss”:0}’) 
let aaa = obj.cardtype.length 
 
class A{ 
  lictype: string = “”; 
  time: string = “”; 
  cardtype: Array<string> = new Array(); 
  ss: number = 0; 
}
