我不明白的是，在 Gmails 文档中，它说上传附件时要使用此网址.
 POST https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=multipart
或者说使用这个网址更可靠...
 POST https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=resumable
我什至没有看到我什至会在何处使用该 URL.在类(Google_Client、Google_Service_Gmail、Google_Service_Gmail_Message)中的任何地方都无法使用该选项.
解决方案
您在 google 文档 尝试使用:分段上传:uploadType=multipart 或可恢复上传:uploadType=resumable
据说这应该是如何工作的
# 发送消息...$message = $gmail->users_messages->send("me", $msg, ['uploadType' => 'multipart']);
如果需要这里的 api 参考 link
I need help understanding Gmails API and how I can fix my script below. I have gone through every post on Stack and all the documentation on Gmail to try and figure out how to send an email using the api with attachments over 5 Mb.
Here is my script. This works fine if the attachments are less than 5Mb. The instant it goes over, I get the 413 error.

    try {
    
        # Prepare the message in message/rfc822
        $mime = rtrim(strtr(base64_encode($strRawMessage), '+/', '-_'), '=');
        $msg = new \Google_Service_Gmail_Message();
        $msg->setRaw($mime);
    
        # send the message...
        $message = $gmail->users_messages->send("me", $msg);
    
        echo '<pre>';
        print_r($message);
        echo '</pre>';
        die;
    
    } catch (\Exception $e) {
        echo '<pre>';
        print_r($e->getMessage());
        echo '</pre>';
        die;
    }
What I do not understand is that in Gmails docs it says to use this url when uploading attachments.
 POST https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=multipart
Or it says to use this URL to be more reliable...
 POST https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=resumable
What I dont see is where I would even use that URL at all. No where in the classes (Google_Client, Google_Service_Gmail, Google_Service_Gmail_Message) is that option even available to use.
解决方案
You have a similar error as found here in the google documentations  Try using:
Multipart upload: uploadType=multipart or Resumable upload: uploadType=resumable

and supposedly this is how should work 
# send the message...
$message = $gmail->users_messages->send("me", $msg, ['uploadType' => 'multipart']);
if needed here the api reference link
