Demonstrates how to send a JSON POST and then parse the JSON response.

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

Chilkat.JsonObject json = new Chilkat.JsonObject();

bool success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json");
if (success != true) {
    Debug.WriteLine(json.LastErrorText);
    return;
}

Chilkat.Http http = new Chilkat.Http();

Chilkat.HttpResponse resp = await http.PostJson2Async("https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums","application/json",json.Emit());
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Chilkat.JsonObject jsonResp = new Chilkat.JsonObject();
jsonResp.Load(resp.BodyStr);

jsonResp.EmitCompact = false;
Debug.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.  
string lifeAmount = jsonResp.StringOf("LifeAmount");
string lifeResidualAmount = jsonResp.StringOf("LifeResidualAmount");

Debug.WriteLine("LifeAmount = " + lifeAmount);
Debug.WriteLine("LifeResidualAmount = " + lifeResidualAmount);
