Hello All, Im trying to figure out, how i can upload multi records using below example in ktor. I dont see this possiblity using

call.receive

Example json:

{Key:[{Var:value, var:value},{Var:value, var:value}]}

Any idea how i can handle more that one in single route? Also did its possible to combine two keys in one route?

I don't think I fully understood your problem but if

value

is a string then receiving works with the following code:

fun main() {
    embeddedServer(Netty, port = 8080) {
        install(ContentNegotiation) {
            json()
        }

        routing {
            post("/json") {
                val r = call.receive<Request>()
                println(r)
            }
        }
    }.start()
}

@Serializable
data class Request(val Key: List<Entry>)
@Serializable
data class Entry(@SerialName("Var") val var1: Value, @SerialName("var") val var2: Value)
typealias Value = String

I need to insert two types of objects in one route. These objects have diffrent values(String, Int, boolean) I have object1 and few object2. Objects one is document header and object2 are single lines of document body. How i should handle it? I have postgres db and when i need post new single object i use call.receive<myDataClass> and pass return value to insert fun()

Could you please share a valid JSON example? How do you determine which type of object to receive if there could be two of them?

Example JSON:

{"Header": {

    

"OrderNo":"someInt",

    

"Created by":"someString",

    

"Company":"someString",

    

"Status":"someString",

    

"CreateDate":"someLong",

    

"EstimateDate":"someLong",

    

"EndDate":"someLong",

    

"Assigned to":"someString",

    

"Priority":"someBool",

    

"Reference":"someString"},

"Body1":{

    

"headerID":"someInt",

    

"Item":"someString",

    

"Quantity":"someInt",

    

"Position":"someString",

    

"Warehouse":"someString",

    

"Confirmation":"someBool"},

"Body2":{

    

"headerID":"someInt",

    

"Item":"someString",

    

"Quantity":"someInt",

    

"Position":"someString",

    

"Warehouse":"someString",

    

"Confirmation":"someBool"

    

}}

Please correct me if I am wrong, the

Header

is the details of an order and each

Body

element is the details of an item in that order. If so then I suggest making an array for a list of items:

{
  "Header": {
    "OrderNo": "someInt",
    "Created by": "someString",
    "Company": "someString",
    "Status": "someString",
    "CreateDate": "someLong",
    "EstimateDate": "someLong",
    "EndDate": "someLong",
    "Assigned to": "someString",
    "Priority": "someBool",
    "Reference": "someString"
  },
  "Items": [
    {
      "headerID": "someInt",
      "Item": "someString",
      "Quantity": "someInt",
      "Position": "someString",
      "Warehouse": "someString",
      "Confirmation": "someBool"
    },
    {
      "headerID": "someInt",
      "Item": "someString",
      "Quantity": "someInt",
      "Position": "someString",
      "Warehouse": "someString",
      "Confirmation": "someBool"
    }
  ]
}

So to deserialize it you will need to have a class for the root JSON object, a class for a header, and a class for an item. Does it make sense?
