如何使用Gmail API在Gmail中“标记为已读”电子邮件？

Question

I have used Gmail API for reading Mails and it's working fine. I was successfully able to do that. But as I want that particular email as "Mark as Read" ( Note : "Mark as Read" not apply the label here) whenever I read that email through Gmail API, I was unable to do so. Actually, I didn't find any method to do so through Gmail API. Is there any way to do so?

PS: I'm using PHP for this process.

You have to modify the message, and remove the UNREAD label.

POST https://www.googleapis.com/gmail/v1/users/me/messages/{MESSAGE_ID}/modify?access_token={ACCESS_TOKEN}

{
 "removeLabelIds": [
  "UNREAD"
 ]
}

Using the Gmail API PHP client you could do something like the following:

$mods = new Google_Service_Gmail_ModifyMessageRequest();
$mods->setRemoveLabelIds(array("UNREAD"));
$message = $service->users_messages->modify($userId, $messageId, $mods);
