尝试使用 SwiftMailer 和 Sendgrid 发送电子邮件时出现致命错误 [英] Fatal error when trying to send email using SwiftMailer and Sendgrid
问题描述
我在尝试使用 swiftmailer 和 sendgrid smtp 发送电子邮件时遇到此错误
I'm getting this error when trying to send an email using swiftmailer and the sendgrid smtp
致命错误: *未捕获的异常Swift_TransportException"，消息预期响应代码 250，但得到代码"，消息"'*
Fatal error: *Uncaught exception 'Swift_TransportException' with message 'Expected response code 250 but got code "", with message ""'*
这是我的代码:
$hdr = new SmtpApiHeader();
// Set all of the above variables
$hdr->addTo($toList);
$hdr->addSubVal('-name-', $nameList);
$hdr->addSubVal('-time-', $timeList);
// Specify that this is an initial contact message
$hdr->setCategory("initial");
// The subject of your email
$subject = 'Example SendGrid Email';
// Where is this message coming from. For example, this message can be from
// support@yourcompany.com, info@yourcompany.com
$from = array('no-reply@mupiz.com' => 'Mupiz');
$to = array('antonin@noos.fr'=>'AN',"antonin@mupiz.com"=>"AN2s");
$text="Hello -name-

";
// Your SendGrid account credentials
$username = 'XXXX';
$password = 'XXXX';
// Create new swift connection and authenticate
$transport = Swift_SmtpTransport::newInstance('smtp.sendgrid.net', 25);
$transport ->setUsername($username);
$transport ->setPassword($password);
$swift = Swift_Mailer::newInstance($transport);
// Create a message (subject)
$message = new Swift_Message($subject);
// add SMTPAPI header to the message
// *****IMPORTANT NOTE*****
// SendGrid's asJSON function escapes characters. If you are using Swift Mailer's
// PHP Mailer functions, the getTextHeader function will also escape characters.
// This can cause the filter to be dropped.
$headers = $message->getHeaders();
$headers->addTextHeader('X-SMTPAPI', $hdr->asJSON());
// attach the body of the email
$message->setFrom($from);
$message->setBody($html, 'text/html');
$message->setTo($to);
$message->addPart($text, 'text/plain');
// send message
if ($recipients = $swift->send($message, $failures))
{
// This will let us know how many users received this message
// If we specify the names in the X-SMTPAPI header, then this will always be 1.
echo 'Message sent out to '.$recipients.' users';
}
// something went wrong =(
else
{
echo "Something went wrong - ";
print_r($failures);
}
一个想法?
谢谢
推荐答案
导致这种情况的原因可能有很多.最有可能的情况是您的服务器已关闭与外部主机的连接.其他可能性是您使用的旧版 PHP 存在 openSSL 错误，或者您的速率受到某些限制.
There could be a number of things causing this. The most likely one is that your server has connecting to external hosts turned off. Other possibilities are that you're using an old version of PHP that has an openSSL error or that you're being rate limited by something.
您应该查看此问题以了解有关外部主机问题的详细信息:通过 sendgrid 发送邮件
You should take a look at this question for details on the external host issue: send mails via sendgrid
另外，如果您想使用 SendGrid 发送电子邮件，您应该使用 SendGrid PHP 库.它解决了 Swift 和发送的一大堆微妙的细微差别.此外，它还允许您访问 HTTP API，以防您因任何原因无法使用 SMTP.
On a separate note, you should use the SendGrid PHP library if you want to send emails using SendGrid. It addresses a whole bunch of subtle nuances with Swift and sending in general. Also, it gives you access to the HTTP API in case you can't use SMTP for whatever reason.
