(JavaScript) HTTP POST JSON and Parse JSON Response

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

Note: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var json = new CkJsonObject();

success = json.LoadFile("qa_data/json/jsonBodyForHttpPost.json");
if (success == false) {
    console.log(json.LastErrorText);
    return;
}

var http = new CkHttp();

var resp = new CkHttpResponse();
success = http.HttpJson("POST","https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums",json,"application/json",resp);
if (success == false) {
    console.log(http.LastErrorText);
    return;
}

var jsonResp = new CkJsonObject();
jsonResp.Load(resp.BodyStr);

jsonResp.EmitCompact = false;
console.log(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.  
var lifeAmount = jsonResp.StringOf("LifeAmount");
var lifeResidualAmount = jsonResp.StringOf("LifeResidualAmount");

console.log("LifeAmount = " + lifeAmount);
console.log("LifeResidualAmount = " + lifeResidualAmount);
