(Perl) Send JSON REST Request, Get JSON Response

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON).

# This example will create a bucket in Google Cloud Storage.

# It requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$gAuth = chilkat::CkAuthGoogle->new();
# Obtain an access token as shown in one of the following examples:
# See Get Access Token using a Service Account JSON Key
# See Get Access Token using a P12 File

# Connect using TLS.

$success = $rest->Connect("www.googleapis.com",443,1,$bAutoReconnect);

# Provide the authentication credentials (i.e. the access key)
$success = $rest->SetAuthGoogle($gAuth);

# Build the JSON request body for creating a bucket.
# The only required property is the "name", but we'll add more
# to make a better example..

# pObjVersioning is a JsonObject
$pObjVersioning = $jsonReqBody->ObjectOf("versioning");
$success = $pObjVersioning->AddBoolAt(-1,"enabled",1);

# Show the HTTP request body we'll be sending.
print $jsonReqBody->emit() . "\r\n";

# Add the required query parameter.
# See https://cloud.google.com/storage/docs/json_api/v1/buckets/insert

# Add the Content-Type HTTP request header.
