如何在sendgrid中添加標題？

我正試圖使用php和sendgrid在outlook上發送日曆邀請。所以我需要創建一個不是問題的ics文件。問題是我需要設置標題。 Gmail會將ics文件識別爲日曆邀請，但Outlook不會。這是我提出的完整代碼，但我無法在這裏完成。請幫忙。我搜索了每個博客，以瞭解如何在sendgrid中添加頭文件（如content-type和content-disposition），但無濟於事。如何在sendgrid中添加標題？

<html> 
<head> 
    <title>PHP Test</title> 
</head> 
<body> 

<?php 

include("/Users/aaa/Downloads/sendgrid-php/sendgrid-php.php"); 
include('/Users/aaa/Downloads//smtpapi-php/smtpapi-php.php'); 


$sendgrid = new SendGrid("uname", "pass"); 
$email = new SendGrid\Email(); 

$ical = " 
Content-Type: text/calendar;method=request

$filename = "invite.ics"; 
$file = fopen($filename, 'w'); 
fwrite($file, $ical); 
fclose($file); 


$email->addTo("[email protected]") 
    ->setFrom("[email protected]") 
    ->setSubject("Subject") 
    ->setAttachment($filename) 
    ->addHeader('Content-Type', 'multipart/alternative') 
    ->addHeader('Content-Disposition', 'inline'); 

$sendgrid->send($email); 

var_dump($sendgrid); 

try { 
    $sendgrid->send($email); 
} catch(\SendGrid\Exception $e) { 
    echo $e->getCode(); 
    foreach($e->getErrors() as $er) { 
     echo $er; 
    } 
} 

?>

不幸的是，這是當前Web端點的限制。對於這種用例，您需要通過SMTP而不是HTTP進行發送。如果您正在使用它們，請使用smtpapi-php庫來構建您的X-SMTPAPI標頭。然後建立您的SMTP郵件與您選擇的圖書館，添加您的自定義標題（如果需要，包括X-SMTPAPI），併發送它。

Example using Swift Mailer as the SMTP transport

use Smtpapi\Header; 

$transport = \Swift_SmtpTransport::newInstance('smtp.sendgrid.net', 587); 
$transport->setUsername('sendgrid_username'); 
$transport->setPassword('sendgrid_password'); 

$mailer = \Swift_Mailer::newInstance($transport); 

$message = new \Swift_Message(); 
$message->setTos(array('[email protected]')); 
$message->setFrom('[email protected]'); 
$message->setSubject('Hello'); 
$message->setBody('%how% are you doing?'); 

$header = new Header(); 
$header->addSubstitution('%how%', array('Owl')); 

$message_headers = $message->getHeaders(); 
$message_headers->addTextHeader(HEADER::NAME, $header->jsonString()); 

try { 
    $response = $mailer->send($message); 
    print_r($response); 
} catch(\Swift_TransportException $e) { 
    print_r('Bad username/password'); 
}
