如何在Webklex中下载附件

Question

我正在使用laravel webklex收发电子邮件，但我不知道如何下载附件。我正在为移动API返回JSON编码。

    $oFolder = $oClient->getFolder($folder_name);
    $oMessage = $oFolder->getMessage($message_id, null, null, true, true, false);

    $oMessage->getAttachments(true);
    // how to make this downloadable inside my return result

    $result['email_details'] = [
     'id' => "some id",
     'message' => "email message",
     'attachment' => "link for the attachment ",
    ];

    return response()->json($result);
