GoogleのGmail API添付ファイルをダウンロード

Question

新しいGmail APIにPHP SDKを使用しています。電子メールから添付ファイルを取得するにはどうすればよいですか？

HereはAPIのドキュメントですが、この例ではPHPの例がありません。私は人々がPHPでこれを達成するのを見ましたが。

EDIT：

これは、それが正しいだ場合、私は今のところ、不明な点が持っているものである：それはあなたに動作するかどう

$attachmentData = $service->users_messages_attachments->get($emailAccount, $messageId, $attachmentId); 

$myfile = fopen("excel.xlsx", "w"); 
fwrite($myfile, $attachmentData); 
fclose($myfile); 

Answer 1

まず、我々は添付ファイルのオブジェクトからデータを取得する必要があります：標準のRFC 4648のbase64エンコードにデータを変換し、ファイルに書き込む前に

その後

$attachmentObj = $service->users_messages_attachments->get($emailAccount, $messageId, $attachmentId); 
$data = $attachmentObj->getData(); //Get data from attachment object 

：

$data = strtr($data, array('-' => '+', '_' => '/')); 
$myfile = fopen("excel.xlsx", "w+");; 
fwrite($myfile, base64_decode($data)); 
fclose($myfile); 

それが機能するようになりました！
