JSON data analysis of kotlin learning

Through this article , You can learn

1. How to base on json Data create a corresponding data class
2. How to base on json Data create an object

（ One ） according to json Data create a corresponding data class

data class Test(
    val code : Int,
    val message : String,
    val warnMessage : String,
    val data : List<Data>
)

data class Data(
    val departmentCode : String,
    val departmentName : String,
    val dutyInfo : List<DutyInfo>
)

data class DutyInfo(
    val doctorCode : String,
    val doctorName : String,
    val departmentCode : String,
    val jobTitle : String,
    val doctorProfile : String,
    val restTicket : String,
    val dutyDate : String,
    val photo : String,
    val duty : List<Duty>
)

data class Duty(
    val dutyTimeName : String,
    val dutyWeek : Int,
    val totalTicket : Int,
    val restTicket : Int,
    val dutyDate : String
)

It should be noted that stay json in , If the data is used {} modification , Then it means that you need to create an object ; If it is to use 【】 modification , Then you need to create an array list

（ Two ） How to base on json Data create an object

If it's a list type

    // Incoming json Is a list type 
    val json = "{\"code\":\"00001\",\"message\":\"test\",\"warnMessage\":\"test\"}"

    val gson = Gson()

    val account : Test = gson.fromJson(json,Test::class.java)

If it's an array type

    // Incoming json Is an array type 
    val jsonArray = "[{\"zoneNumber\":\"00001\",\"roomNumber\":\"test\",\"bedNumber\":\"test\"}]"

    val inf : List<InpatientInfo> = gson.fromJson(jsonArray, object : TypeToken<List<InpatientInfo>>(){
    }.type)
