(Ruby) RDAP Domain Lookup using rdap.org

Demonstrates doing an RDAP domain lookup using the rdap.org public RDAP server.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

http = Chilkat::CkHttp.new()

# Send HTTP requests to https://rdap.org/<type>/<object>, where <type> is the object type (one of domain, ip, autnum, entity etc)
# and <object> is the object identifier (eg example.com, 192.168.0.1, 64496, etc).

# For example, here's a lookup for "oracle.com"
sbResponse = Chilkat::CkStringBuilder.new()
success = http.QuickGetSb("https://rdap.org/domain/oracle.com",sbResponse)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

statusCode = http.get_LastStatus()
if (statusCode != 200)
    print "Error response:" + "\n";
    print sbResponse.getAsString() + "\n";
    print "status code: " + statusCode.to_s() + "\n";
    exit
end

# Load the JSON response and examine..

# Use this online tool to generate parsing code from sample JSON: 
# Generate Parsing Code from JSON

json = Chilkat::CkJsonObject.new()
json.LoadSb(sbResponse)
json.put_EmitCompact(false)
print json.emit() + "\n";

# Here's a sample response, and the parsing code generated from the above online tool follows..
