Yii2版本:2.0.3
SwiftMail版本:v5.3.1
使用定时任务发邮件时,由于swiftmailer长时间运行没有关闭transport,造成SSL连接出错。
报错1:
exception 'Swift_TransportException' with message 'Expected response code 250 but got code "", with message ""' in vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:383
报错2:
exception 'yii\base\ErrorException' with message 'fwrite(): SSL: Broken pipe' in vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:232
解决方案:
1.修改vendor/swiftmailer/swiftmailer/lib/classes/Swift/Mailer.php:90
public function send(Swift_Mime_Message $message, &$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; } } catch (\Exception $exception) { $this->_transport->stop(); sleep(10); throw $exception; } finally { $this->_transport->stop(); sleep(1); } return $sent; }
2.在调用发送邮件处进行失败重试
/** * @return bool */ private function sendEmail() { $tmpPath = \Yii::$app->getRuntimePath() . '/logs/'; $tmpFilePath = File::downFileForNotExist($tmpPath, $this->filePath); $result = \Yii::$app->mailer->compose() ->setTo($this->emailTo) ->setFrom(['nick@lampnick.com' => 'lampNick']) ->setSubject($this->subject) ->setTextBody($this->body) ->attach($tmpFilePath) ->send(); @unlink($tmpFilePath); return $result; } /** * 尝试发邮件 */ private function trySendMail() { $tryCount = self::TRY_COUNT; while ($tryCount > 0) { try { $sendResult = $this->sendEmail(); if (!$sendResult) { throw new SendMailAsynException; } return; } catch (\Exception $e) { $tryCount--; \Yii::error("swiftMailer发邮件失败,重试发送,失败原因是:" . (string)$e); \Yii::getLogger()->flush(true); $this->trySendMail(); } } }
