// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim json As New Chilkat.JsonObject

Dim success As Boolean
success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json")
If (success <> True) Then
    System.DebugLog(json.LastErrorText)
    Return
End If

Dim http As New Chilkat.Http

Dim resp As Chilkat.HttpResponse
resp = http.PostJson2("https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums","application/json",json.Emit())
If (http.LastMethodSuccess <> True) Then
    System.DebugLog(http.LastErrorText)
    Return
End If

Dim jsonResp As New Chilkat.JsonObject
success = jsonResp.Load(resp.BodyStr)

jsonResp.EmitCompact = False
System.DebugLog(jsonResp.Emit())

// The JSON response to be parsed looks like this:
// {
//   "LifeAmount": 513.85,
//   "LifeResidualAmount": 123.38,
//   "CriticalIllnessAmount": 0,
//   "CriticalIllnessResidualAmount": 0,
//   "DisabilityAmount": 881.70,
//   "PolicyFee": 0.00,
//   "PolicyFeeSecondary": 0,
//   "PolicyFeeHidden": 50.00,
//   "PolicyFeeHiddenSecondary": 0
// }

// We can get the floating point numbers as strings.  Then convert to double
// using the appropriate string-to-double conversion for your programming language.
// For example, in C++ use atof.  In C# use Convert.ToDouble.  
Dim lifeAmount As String
lifeAmount = jsonResp.StringOf("LifeAmount")
Dim lifeResidualAmount As String
lifeResidualAmount = jsonResp.StringOf("LifeResidualAmount")

System.DebugLog("LifeAmount = " + lifeAmount)
System.DebugLog("LifeResidualAmount = " + lifeResidualAmount)
