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

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

Chilkat Perl Downloads Perl Module for Windows, MacOS, Linux, Alpine Linux

use chilkat();

$success = 0;

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

$json = chilkat::CkJsonObject->new();

$success = $json->LoadFile("qa_data/json/jsonBodyForHttpPost.json");
if ($success == 0) {
    print $json->lastErrorText() . "\r\n";
    exit;
}

$http = chilkat::CkHttp->new();

$resp = chilkat::CkHttpResponse->new();
$success = $http->HttpJson("POST","https://test.something.com/XYZ/API/v1/CreditInsuranceCalculator/CalculatePremiums",$json,"application/json",$resp);
if ($success == 0) {
    print $http->lastErrorText() . "\r\n";
    exit;
}

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

$jsonResp->put_EmitCompact(0);
print $jsonResp->emit() . "\r\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 . "\r\n";
print "LifeResidualAmount = " . $lifeResidualAmount . "\r\n";
