请问HarmonyOS有没有Json格式转HashMap的方法？

class User { 
  id: number; 
  name: string; 
} 
 
function test() { 
  let data = ‘{“id”:“xxxx”, “name”:“你好”, “age”:18}’ 
  let user :User = JSON.parse(data) 
 
  console.log(JSON.parse(user)) 
 
  // 实际输出为 {“id”:“xxxx”, “name”:“你好”, “age”:18} 
  // 期望输出为 {“id”:undefined, “name”:“你好”} 
}

class User { 
  id: number; 
  name: string; 
} 
 
function test() { 
  let data = ‘{“id”:“xxxx”, “name”:“你好”, “age”:18}’ 
  let user :User = JSON.parse(data) 
 
  console.log(JSON.parse(user)) 
 
  // 实际输出为 {“id”:“xxxx”, “name”:“你好”, “age”:18} 
  // 期望输出为 {“id”:undefined, “name”:“你好”} 
}
