Demonstrates how to upload a photo for a Google Contact.

// 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

Chilkat.JsonObject jsonToken = new Chilkat.JsonObject();
bool success = jsonToken.LoadFile("qa_data/tokens/googleContacts.json");
if (success != true) {
    Debug.WriteLine("Failed to load googleContacts.json");
    return;
}

Chilkat.AuthGoogle gAuth = new Chilkat.AuthGoogle();
gAuth.AccessToken = jsonToken.StringOf("access_token");

Chilkat.Rest rest = new Chilkat.Rest();

// Connect using TLS.
bool bAutoReconnect = true;
success = await rest.ConnectAsync("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 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]

rest.AddHeader("GData-Version","3.0");
rest.AddHeader("If-Match","*");
rest.AddHeader("Content-Type","image/*");

Chilkat.StringBuilder sbPath = new Chilkat.StringBuilder();
sbPath.Append("/m8/feeds/photos/media/default/{contactId}");
// Upload a photo for the contact having contactId = "1ea2e4fe0ef24e09"
int numReplacements = sbPath.Replace("{contactId}","1ea2e4fe0ef24e09");

// Let's get our photo data..
Chilkat.BinData pngData = new Chilkat.BinData();
success = pngData.LoadFile("qa_data/png/dude.png");

Chilkat.StringBuilder sbResponseBody = new Chilkat.StringBuilder();
success = await rest.FullRequestBdAsync("PUT",sbPath.GetAsString(),pngData,sbResponseBody);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// A successful response will have a status code equal to 200.
if (rest.ResponseStatusCode != 200) {
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body: " + sbResponseBody.GetAsString());
    return;
