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

# This example shows how to use the Chilkat socket object's connection.
rest = Chilkat::CkRest.new()
socket = Chilkat::CkSocket.new()

# Set the certificate to be used for mutual TLS authentication
cert = Chilkat::CkCert.new()

# If the smartcard or token requires a PIN...
cert.put_SmartCardPin("000000")

success = cert.LoadFromSmartcard("")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

success = socket.SetSslClientCert(cert)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
end

# Establish the connection using the socket object (with client certificate authentication).
bTls = true
port = 443
maxWaitMs = 5000
success = socket.Connect("www.example.com",port,bTls,maxWaitMs)
if (success != true)
    print "Connect Failure Error Code: " + socket.get_ConnectFailReason().to_s() + "\n";

bAutoReconnect = true

# Use the connection:
success = rest.UseConnection(socket,bAutoReconnect)
if (success != true)
    print rest.lastErrorText() + "\n";
    exit
end

# At this point we are connected and can make REST calls...
# For example..
responseJson = rest.fullRequestNoBody("GET","/someQuery")
if (rest.get_LastMethodSuccess() != true)
    print rest.lastErrorText() + "\n";
