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

# This example connects to a REST server through an HTTP proxy.
# It will connect to the Amazon AWS service for this example.
rest = chilkat.CkRest()
socket = chilkat.CkSocket()

# Set the HTTP proxy domain or IP address, and port.
socket.put_HttpProxyHostname("192.168.1.100")
socket.put_HttpProxyPort(8088)

# We want to tell the socket object that we're doing HTTP over the proxy connection.
# This is because an HTTP proxy used for other protocols (IMAP, SMTP, SSH, FTP, etc.) 
# can require some internal differences in behavior (i.e. how we do things).
socket.put_HttpProxyForHttp(True)

# Other properties exist for specifying a proxy login, password, and authentication method (such as NTLM),
# but these are not used in this example.

# Connect through the HTTP proxy to the Amazon AWS server for the S3 service.

port = 443

    print(socket.lastErrorText())
    sys.exit()

# Use the proxied TLS connection:
success = rest.UseConnection(socket,True)
if (success != True):
    print(rest.lastErrorText())
    sys.exit()

# Provide AWS credentials for the REST call.
authAws = chilkat.CkAuthAws()
authAws.put_AccessKey("AWS_ACCESS_KEY")
authAws.put_SecretKey("AWS_SECRET_KEY")

# Show the full XML returned.

# Iterate over the buckets, showing each bucket name.
