<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

// Use the Chilkat Email API to create or load an email.
$email = new CkEmail();

// The From name/address don't need to be specified. 
// GMail will automatically use your Gmail address if the following 2 lines are omitted.
$email->put_FromName('My Name');
$email->put_FromAddress('my_account_name@gmail.com');

$email->AddTo('John Smith','somebody@somewhere.com');
// To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

// -----------------------------------------------------------------------------------------
// This section of this example demonstrates how to add BCC recipients.
// 
// Technically, an email should never contain a "Bcc" MIME header because it would
// effectively nullify the purpose of BCC -- which means "Blind Carbon Copy".
// Email recipients should not be able to see the BCC recipients.
// Chilkat never adds a "Bcc" header field.
// However.. in this case, the GMail REST server will look for the Bcc header field,
// and will include those email addresses when sending, and also removes the Bcc header
// from the email that is sent.
// 
// Starting in Chilkat v9.5.0.91, we can tell the email object to add the Bcc header
// using the "UseBccHeader" UncommonOptions.  For example:
$email->put_UncommonOptions('UseBccHeader');
$email->AddBcc('Joe','joe@example.com');
$email->AddBcc('Dave','dave@example.com');
// ...
// -----------------------------------------------------------------------------------------

$email->put_Subject('This is a test GMail email created using Chilkat.');
$email->put_Charset('utf-8');
$email->AddPlainTextAlternativeBody('This is a test');

// Create an HTML email body with an embedded image.
$cid = $email->addRelatedFile('qa_data/jpg/starfish.jpg');
$sbHtml = new CkStringBuilder();
$sbHtml->Append('<html><body>This is a <b>test</b><br><img src=\'cid:STARFISH_CID\'/></body></html>');
$numReplacements = $sbHtml->Replace('STARFISH_CID',$cid);

$email->AddHtmlAlternativeBody($sbHtml->getAsString());

// OK.. we now have an HTML email with an embedded JPG image
// We'll need to get the full MIME of the email encoded to a base64url string.
$sbMime = new CkStringBuilder();
$email->GetMimeSb($sbMime);
$sbMime->Encode('base64url','utf-8');

// The body of the HTTP request will be JSON..
$json = new CkJsonObject();
$json->UpdateSb('raw',$sbMime);

// Send the email...
$http = new CkHttp();
$http->put_AuthToken('GMAIL-ACCESS-TOKEN');

$url = 'https://www.googleapis.com/gmail/v1/users/me/messages/send';
// resp is a CkHttpResponse
$resp = $http->PostJson3($url,'application/json',$json);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

// A status code of 200 indicates success.
print 'Response status code: ' . $resp->get_StatusCode() . "\n";
print 'Response body:' . "\n";
print $resp->bodyStr() . "\n";

// The response body contains JSON.
// Use the online tool at Generate JSON Parsing Code
// to generate JSON parsing code.

// A sample successful JSON response:

// {
//  "id": "166f0d4ac39e50bf",
//  "threadId": "166f0d4ac39e50bf",
//  "labelIds": [
//   "SENT"
//  ]
// }
