<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");
$http->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';
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbJson = new COM("Chilkat.StringBuilder");
$success = $http->DownloadSb($url,'utf-8',$sbJson);
if ($success != 1) {
    print $http->LastErrorText . "\n";
    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->LoadSb($sbJson);
$json->EmitCompact = 0;

if ($http->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..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbRaw = new COM("Chilkat.StringBuilder");
$json->StringOfSb('raw',$sbRaw);
$sbRaw->Decode('base64url','utf-8');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Email')
$email = new COM("Chilkat.Email");
$email->SetFromMimeSb($sbRaw);

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