(PHP ActiveX) HTTP POST JSON and Parse JSON Response

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// 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 new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");

$success = $json->LoadFile('qa_data/json/jsonBodyForHttpPost.json');
if ($success != 1) {
    print $json->LastErrorText . "\n";
    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// resp is a Chilkat.HttpResponse
$resp = $http->PostJson2('https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums','application/json',$json->emit());
if ($http->LastMethodSuccess != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonResp = new COM("Chilkat.JsonObject");
$jsonResp->Load($resp->BodyStr);

$jsonResp->EmitCompact = 0;
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.  
$lifeAmount = $jsonResp->stringOf('LifeAmount');
$lifeResidualAmount = $jsonResp->stringOf('LifeResidualAmount');

print 'LifeAmount = ' . $lifeAmount . "\n";
print 'LifeResidualAmount = ' . $lifeResidualAmount . "\n";
