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

# --------------------------------------------------------------------------------------------------------
# Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
# Once connected, the REST object may be re-used for many REST API calls.
# (It's a good idea to put the connection setup code in a separate function/subroutine.)
# --------------------------------------------------------------------------------------------------------

# It is assumed we previously obtained an OAuth2 access token.
# This example loads the JSON access token file 
# saved by this example: Get Google Contacts OAuth2 Access Token

jsonToken = chilkat.CkJsonObject()
success = jsonToken.LoadFile("qa_data/tokens/googleContacts.json")
if (success != True):
    print("Failed to load googleContacts.json")

gAuth = chilkat.CkAuthGoogle()
gAuth.put_AccessToken(jsonToken.stringOf("access_token"))

rest = chilkat.CkRest()

# Connect using TLS.
bAutoReconnect = True
success = rest.Connect("www.google.com",443,True,bAutoReconnect)

# Provide the authentication credentials (i.e. the access token)
rest.SetAuthGoogle(gAuth)

# ----------------------------------------------
# OK, the REST connection setup is completed..
# ----------------------------------------------

# To update a contact, we'll first get the contact information,
# then we'll make changes to the XML and then PUT the update.

# To retrieve the contact, send the following:
# 	GET /m8/feeds/contacts/default/full/{contactId}
# 	GData-Version: 3.0
