Question

我尝试使用php和sendgrid在outlook上发送日历邀请。所以我需要创建一个不是问题的ics文件。问题是我需要设置标题。 Gmail将ics文件识别为日历邀请，但Outlook不会。这是我提出的整个代码，但我在这方面无处可去。请帮忙。我搜索了每个博客，了解如何在sendgrid中添加内容类型和内容处置等标题，但无济于事。

<html>
<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

END:VCALENDAR";

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


$email->addTo("aaa@outlook.com")
    ->setFrom("aaa@example.com")
    ->setSubject("Subject")
    ->setAttachment($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，这是当前Web端点的限制。对于此用例，您需要通过SMTP而不是HTTP发送。如果您正在使用它们，请使用smtpapi-php库来构建X-SMTPAPI标头。然后使用您选择的库构建SMTP邮件，添加自定义标头（如果需要，包括X-SMTPAPI），然后发送。

http://www.w3schools.com/xsl/xsl_transformation.asp

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('bar@blurdybloop.com'));
$message->setFrom('foo@blurdybloop.com');
$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');
}

如何在sendgrid中添加标头？
