gmail api在发送时作为回复添加标签ID和线程ID(回复时发送具有相同线程ID的邮件)

标签: laravel-4 gmail-api

我正在尝试使用laravel使用gmail api发送邮件。

我发送的消息是

$text = 'From: '.$from.'
To: '.$to.'
Subject:'.$subject.'

'.$body.'';

$encoded_message = rtrim(strtr(base64_encode($text), '+/', '-_'), '=');
$message->setRaw($encoded_message);
$message = $service->users_messages->send($userId, $message);

我尝试编辑标签ID和线程ID,如下所示,

$text = 'labelIds: ':'.SENT.'
'From: '.$from.'
To: '.$to.'
Subject:'.$subject.'

'.$body.'';

,它给出了语法错误。如何为gmail-api添加labelid和线程ID?

EDIT1

发送后我的留言是,

object(Google_Service_Gmail_Message)#1048 (14){  
  [  
  "historyId"
 ]   => string(4) "4171"   [  
  "id"
]   => string(16) "15270b9c7b867bab"   [  
  "internalDate"
]   => string(13) "1453590169000"   [  
  "labelIds"
]   => NULL

这是creating a new threadId,我需要sent it as reply。我怎么能send the mail with same threadId

你现在可能已经解决了这个问题,但我遇到了类似的问题并在寻找解决方案时发现了这个问题,所以我想分享我用过的方法以防其他人需要它。

基于Gmail的API规范

  

1.必须在您提供请求的Message或Draft.Message上指定请求的threadId。
  2.必须根据RFC 2822标准设置References和In-Reply-To标头   3.主题标题必须匹配。

数字2对我来说很复杂,因为我试图手动设置References和In-Reply-To标头。我的想法是从同一个帖子中的最后一条消息中获取它们,但API没有返回那些标题,我设置的内容显然是不准确的。然后,在此线程MIME Headers Not Making it Through Gmail API之后,我删除了所有其他标头,并仅设置了threadId和匹配的主题。

我使用PHPMailer库来格式化mime字符串,而不是手动执行(它减少了出错的可能性)。使用作曲家,你只需要添加" phpmailer / phpmailer":" ~5.2"在你的composer.json的require部分。 这是我的解决方案:

$thread = $gmail->users_threads->get($user_id,$threadId);
if($thread) {
    $opt_param['threadId'] = $threadId;
    $thread_messages = $thread->getMessages($opt_param);
    if($thread_messages) {
        $messageId = $thread_messages[0]->getId();
        $messageDetails = $gmail->users_messages->get($messageId);
        // get the subject here from the headers of $messageDetails. You will use it below as $subject.
    }
}

$message = new Google_Service_Gmail_Message();

$mail = new PHPMailer();
$mail->From = 'YOUR_EMAIL'; // I tried with 'me' here, but PHPMailer doesn't consider it valid, so it can either be the email or userId 
$mail->FromName = 'YOUR_NAME';
$mail->addAddress('RECIPIENT_EMAIL'); // Make sure this is the same as the email in the message you reply to
$mail->Subject = $subject; // the subject from $messageDetails from above
$mail->Body = $body;
$mail->preSend();
$mime = $mail->getSentMIMEMessage();

$raw = rtrim(strtr(base64_encode($mime), '+/', '-_'), '='); // web safe base64 encode
$message->setRaw($raw); // You set the thread id to your message object now, separately from the other headers
$message->setThreadId($threadId); 

$gmail->users_messages->send($user_id, $message);

上面使用的变量:

$gmail - your instance of Google_Service_Gmail;
$user_id - the id of the authenticated user (can be 'me' for the current logged in user);
$threadId - the thread under which you want to send your email

希望这有用。
