php - 为什么将 null 转换为数组会退出代码?
问题描述
public function send(Swift_Mime_SimpleMessage $message, &$failedRecipients = null)
{
$failedRecipients = (array) $failedRecipients;
if (!$this->transport->isStarted()) {
$this->transport->start();
}
$sent = 0;
try {
$sent = $this->transport->send($message, $failedRecipients);
} catch (Swift_RfcComplianceException $e) {
foreach ($message->getTo() as $address => $name) {
$failedRecipients[] = $address;
}
}
return $sent;
}
这是来自 vendor/swiftmailer/swiftmailer/lib/classes/Swift/Mailer.php 的代码
它首先运行良好,我们还有另一个使用相同库的项目,它在该项目上运行良好。但在一个项目上线
$failedRecipients = (array) $failedRecipients;
它没有给出任何错误,就像这条线会从函数调用返回一样。所以电子邮件不会发送。$failedRecipients 为空。
PHP 版本是 7.2.26,它应该可以正常工作,在另一个项目上它是相同的。
更新
Zelay'da要求的信息:
$address 将是电子邮件地址字符串,name 将是 null 代码来了。我从 $message->getTo() 中获取了它们。传输对象是 vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/SpoolTransport.php

解决方案
SwiftMailer 知道哪些收件人失败了,但 Laravel 没有公开相关参数来帮助我们获取该信息:
/**
* Send the given Message like it would be sent in a mail client.
*
* All recipients (with the exception of Bcc) will be able to see the other
* recipients this message was sent to.
*
* Recipient/sender data will be retrieved from the Message object.
*
* The return value is the number of recipients who were accepted for
* delivery.
*
* @param array $failedRecipients An array of failures by-reference
*
* @return int The number of successful recipients. Can be 0 which indicates failure
*/
public function send(Swift_Mime_SimpleMessage $message, &$failedRecipients = null)
{
$failedRecipients = (array) $failedRecipients;
// FIXME: to be removed in 7.0 (as transport must now start itself on send)
if (!$this->transport->isStarted()) {
$this->transport->start();
}
$sent = 0;
try {
$sent = $this->transport->send($message, $failedRecipients);
} catch (Swift_RfcComplianceException $e) {
foreach ($message->getTo() as $address => $name) {
$failedRecipients[] = $address;
}
}
return $sent;
}
您可以使用以下方法访问失败的收件人以查找错误 Mail::failures()
if(count(Mail::failures()) > 0){
//$errors = 'Failed to send confirmation email, please try again.';
$message = "Email not send";
}
return $message;
这是完整的课程:https ://github.com/swiftmailer/swiftmailer/blob/master/lib/classes/Swift/Mailer.php
Swiftmailer 只负责将电子邮件交给邮件服务器。
其他一切都与 Swiftmailer 无关,请参阅此处了解使用 PHP 处理退回电子邮件?
