// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$json = new CkJsonObject();

$success = $json->LoadFile('qa_data/json/jsonBodyForHttpPost.json');
if ($success != true) {
    print $json->lastErrorText() . "\n";
    exit;
}

$http = new CkHttp();

// resp is a CkHttpResponse
$resp = $http->PostJson2('https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums','application/json',$json->emit());
if ($http->get_LastMethodSuccess() != true) {

    exit;
}

$jsonResp = new CkJsonObject();
$jsonResp->Load($resp->bodyStr());

$jsonResp->put_EmitCompact(false);
print $jsonResp->emit() . "\n";

// 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.
