// 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

CkoJsonObject *jsonToken = [[CkoJsonObject alloc] init];
BOOL success = [jsonToken LoadFile: @"qa_data/tokens/googleContacts.json"];

// Connect using TLS.
BOOL bAutoReconnect = YES;
success = [rest Connect: @"www.google.com" port: [NSNumber numberWithInt: 443] tls: YES autoReconnect: bAutoReconnect];

// Provide the authentication credentials (i.e. the access token)
[rest SetAuthGoogle: gAuth];

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

// To upload a photo for the contact, send the following:

// 	PUT /m8/feeds/photos/media/default/contactId
// 	If-match: Etag
// 	Content-Type: image/*
// 	...
// 	[Photo data bytes]

// Upload a photo for the contact having contactId = "1ea2e4fe0ef24e09"
int numReplacements = [[sbPath Replace: @"{contactId}" replacement: @"1ea2e4fe0ef24e09"] intValue];

// Let's get our photo data..
