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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = CreateObject("Chilkat.JsonObject")

success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json")
If (success <> 1) Then
    outFile.WriteLine(json.LastErrorText)
    WScript.Quit
End If

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = CreateObject("Chilkat.Http")

' resp is a Chilkat.HttpResponse
Set resp = http.PostJson2("https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums","application/json",json.Emit())
If (http.LastMethodSuccess <> 1) Then
    outFile.WriteLine(http.LastErrorText)
    WScript.Quit

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set jsonResp = CreateObject("Chilkat.JsonObject")

jsonResp.EmitCompact = 0
outFile.WriteLine(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.
