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

loJson = createobject("CkJsonObject")

llSuccess = loJson.LoadFile("qa_data/json/jsonBodyForHttpPost.json")
if (llSuccess <> .T.) then
    ? loJson.LastErrorText
    release loJson
    return
endif

loHttp = createobject("CkHttp")

loResp = loHttp.PostJson2("https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums","application/json",loJson.Emit())
if (loHttp.LastMethodSuccess <> .T.) then
    ? loHttp.LastErrorText
    release loJson
    release loHttp
    return
endif

loJsonResp = createobject("CkJsonObject")
loJsonResp.Load(loResp.BodyStr)

loJsonResp.EmitCompact = .F.
? loJsonResp.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.  
lcLifeAmount = loJsonResp.StringOf("LifeAmount")
lcLifeResidualAmount = loJsonResp.StringOf("LifeResidualAmount")

? "LifeAmount = " + lcLifeAmount
? "LifeResidualAmount = " + lcLifeResidualAmount
