如何将JSON字符串映射到Kotlin Map [英] How to map a JSON string to Kotlin Map

问题描述

我有一个简单的Kotlin程序，该程序可以访问Mongo数据库并生成如下所示的JSON字符串；

I have a simple Kotlin program that access a Mongo database and produce a JSON string as below;

"{
     "_id" : { "$oid" : "593440eb7fa580d99d1abe85"} , 
     "name" : "Firstname Secondname" ,
     "reg_number" : "ATC/DCM/1016/230" ,
     "oral" : 11 ,
     "oral_percent" : 73 , 
     "cat_1" : 57 , 
     "cat_2" : 60 , 
     "cat_average" : 59 , 
     "assignment" : 90
}"

如何在Kotlin Map/MutableMap中对此进行映射? Kotlin中是否有API可以读取JSON并将其映射到Map/MutableMap?

How do I map this in Kotlin Map/MutableMap? Is there an API in Kotlin to read JSON and map it to Map/MutableMap?

推荐答案

这可以通过 Klaxon .这样，您可以轻松地将 Json 数据读取为JsonObject，实际上是MutableMap.

This can be done with Klaxon. With this you can easily read the Json data as JsonObject which is actually a MutableMap.

val json: JsonObject = Parser().parse(jsonData) as JsonObject
