(CkPython) REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls.

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

# Connect to an SSH server and establish the SSH tunnel:
success = tunnel.SshOpenTunnel(sshHostname,sshPort)
if (success != True):
    print(tunnel.lastErrorText())

# Authenticate with the SSH server via a login/password
# or with a public key.
# This example demonstrates SSH password authentication.
success = tunnel.SshAuthenticatePw("mySshLogin","mySshPassword")

    print(tunnel.lastErrorText())
    sys.exit()

#  OK, the SSH tunnel is setup.  Now open a channel within the tunnel.
#  (Any number of channels may be created from the same SSH tunnel.
#  Multiple channels may coexist at the same time.)

# This example connects to a REST server through the SSH tunnel.
# It will connect to the Amazon AWS service for this example.

# In other words, TLS is wrapped within the SSH tunnel.)
