<?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.

$http = new CkHttp();
$http->put_AuthToken('GMAIL-ACCESS-TOKEN');

// The id of the GMail message to download.
$id = '166e50fed0b9b0cb';
$userId = 'me';

$http->SetUrlVar('userId','me');
$http->SetUrlVar('id',$id);

// Fetch the email.
$url = 'https://www.googleapis.com/gmail/v1/users/{$userId}/messages/{$id}?format=raw';
$sbJson = new CkStringBuilder();
$success = $http->DownloadSb($url,'utf-8',$sbJson);
if ($success != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

$json = new CkJsonObject();
$json->LoadSb($sbJson);
$json->put_EmitCompact(false);

if ($http->get_LastStatus() != 200) {
    print $json->emit() . "\n";
    print 'Failed.' . "\n";
    exit;
}

// The returned JSON contains something like this:

// {
//   "id": "166e50fed0b9b0cb",
//   "threadId": "166e50fed0b9b0cb",
//   "labelIds": [
//     "CATEGORY_SOCIAL",
//     "INBOX"
//   ],
//   "snippet": "...",
//   "historyId": "582477",
//   "internalDate": "1541441317000",
//   "sizeEstimate": 28603,
//   "raw": "BASE64URL_CONTENT"
// }

// The RFC822 MIME of the email is contained in the "raw" as a base64URL encoded string.
// Let's decode and load into a Chilkat email object..
$sbRaw = new CkStringBuilder();
$json->StringOfSb('raw',$sbRaw);
$sbRaw->Decode('base64url','utf-8');

$email = new CkEmail();
$email->SetFromMimeSb($sbRaw);

// Now we can use the email API to do whatever we desire..
print 'From: ' . $email->fromAddress() . "\n";
print 'Subject: ' . $email->subject() . "\n";
// ...
