仓颉编程语言的这个反序列化和序列化比 go 复杂好多

golang 用 Unmarshal 和 marshal 函数就行了。

仓颉要写这个一大堆，有人反馈这个写法跟 C++有的一拼，但是性能不如 java,go ,c++。

希望官方能优化一下，对初学者友好。

下面是官网的例子。

import serialization.serialization.* import encoding.json.* class Person <: Serializable<Person> { var name: String = "" var age: Int64 = 0 var loc: Option<Location> = Option<Location>.None public func serialize(): DataModel { return DataModelStruct().add(field<String>("name", name)).add(field<Int64>("age", age)).add(field<Option<Location>>("loc", loc)) } public static func deserialize(dm: DataModel): Person { var dms = match (dm) { case data: DataModelStruct => data case _ => throw Exception("this data is not DataModelStruct") } var result = Person() result.name = String.deserialize(dms.get("name")) result.age = Int64.deserialize(dms.get("age")) result.loc = Option<Location>.deserialize(dms.get("loc")) return result } } class Location <: Serializable<Location>{ var country: String = "" var province: String = "" public func serialize(): DataModel { return DataModelStruct().add(field<String>("country", country)).add(field<String>("province", province)) } public static func deserialize(dm: DataModel): Location { var dms = match (dm) { case data: DataModelStruct => data case _ => throw Exception("this data is not DataModelStruct") } var result = Location() result.country = String.deserialize(dms.get("country")) result.province = String.deserialize(dms.get("province")) return result } } main() { var js = ##"{ "name": "A", "age": 30, "loc": { "country": "China", "province": "Beijing" } }"## var jv = JsonValue.fromStr(js) var dm = DataModel.fromJson(jv) var A = Person.deserialize(dm) println("name == ${A.name}") println("age == ${A.age}") println("country == ${A.loc.getOrThrow().country}") println("province == ${A.loc.getOrThrow().province}") println("====================") // 上部分实现从 JSON 字符串到自定义类型的转换，下部分实现从自定义类型到 JSON 字符串的转换。 dm = A.serialize() var jo = dm.toJson().asObject() println(jo.toJsonString()) 0 }
