在 PHP 中使用 Microsoft Graph 更新电子邮件的主题

Question

这是我当前的代码：

require_once '/pathtovendor/vendor/autoload.php';

use Microsoft\Graph\Graph;
use Microsoft\Graph\Model;
use Microsoft\Graph\Http\GraphRequest;

$access_token = "My valid access token";

$graph = new Graph();
$graph->setAccessToken($access_token);

$reply = array( "Comment" => "My reply" );
$message_id = "Valid message ID";

if($graph->createRequest("POST", "/me/messages/".$message_id."/reply")
      ->attachBody($reply)
      ->execute()){
        // I can get to this part OK. Message is replied to.

    //This code doesn't work
    $graph->createRequest("PATCH", "/me/messages/".$message_id)
      ->attachBody(array( "Subject" => "New Subject" ))
      ->execute();
}

我可以运行 GET 和 POST 请求工作，但我不能 PATCH 这样工作。它继续抛出 500 Internal Server Error。感谢任何帮助。

这仅在草稿邮件中受支持。来自 documentation:

subject | String | The subject of the message. Updatable only if isDraft = true.

以下属性只能在草稿消息中更新：

bccRecipients
body
ccRecipients
internetMessageId
replyTo
sender
subject
toRecipients
from
