Prestashop 1.6 和带有 PHP 5.6 版的 SwiftMailer - fsockopen 错误答案

【问题描述】：

我在使用 PS1.6 附带的 Swiftmailer 版本发送邮件时遇到问题

Swift 错误：SMTP 连接无法启动 [ssl://mail.wineofthemonth.co.za:465]：fsockopen 返回错误号 0 和错误字符串 ''

这是因为从 PHP 5.6 开始，verify_peer 选项默认设置为 true。

现在我找到了有关如何将验证对等设置为 false 的各种说明：

$https['ssl']['verify_peer'] = FALSE;
$https['ssl']['verify_peer_name'] = FALSE;

问题是在 Prestashop 中使用的 Swiftmailer 版本中没有地方设置它。

所以我的问题是，在 class/mail.php 或其他任何地方我会将 verify_peer 设置为 false 吗？

这是我认为与此相关的 mail.php 中的一行：

$connection = new Swift_Connection_SMTP(
                    $configuration['PS_MAIL_SERVER'],
                    $configuration['PS_MAIL_SMTP_PORT'],
                    $configuration['PS_MAIL_SMTP_ENCRYPTION'] == 'ssl' ? Swift_Connection_SMTP::ENC_SSL : (($configuration['PS_MAIL_SMTP_ENCRYPTION'] == 'tls' ? Swift_Connection_SMTP::ENC_TLS : Swift_Connection_SMTP::ENC_OFF))
                );

还有一个 sendMailtest 方法可以更加清晰：

public static function sendMailTest($smtpChecked, $smtpServer, $content, $subject, $type, $to, $from, $smtpLogin, $smtpPassword, $smtpPort = 25, $smtpEncryption)
    {
        $result = false;
        try {
            if ($smtpChecked)
            {
                $smtp = new Swift_Connection_SMTP($smtpServer, $smtpPort, ($smtpEncryption == 'off') ?
                    Swift_Connection_SMTP::ENC_OFF : (($smtpEncryption == 'tls') ? Swift_Connection_SMTP::ENC_TLS : Swift_Connection_SMTP::ENC_SSL));
                $smtp->setUsername($smtpLogin);
                $smtp->setpassword($smtpPassword);
                $smtp->setTimeout(5);
                $swift = new Swift($smtp, Configuration::get('PS_MAIL_DOMAIN'));
            }
            else
                $swift = new Swift(new Swift_Connection_NativeMail(), Configuration::get('PS_MAIL_DOMAIN'));

            $message = new Swift_Message($subject, $content, $type);

            if ($swift->send($message, $to, $from))
                $result = true;

            $swift->disconnect();
        } catch (Swift_ConnectionException $e) {
            $result = $e->getMessage();
        } catch (Swift_Message_MimeException $e) {
            $result = $e->getMessage();
        }

        return $result;
    }

或者，在任何 conf 或 ini 文件中，我可以将 verify_peer 设置为 false 吗？

Prestashop 1.6.1.1 到 1.6.1.4 受到影响。

你找到解决办法了吗？

标签： php smtp ssl-certificate prestashop-1.6 swiftmailer

【解决方案1】：

这对我有用：

打开文件/tools/swift/classes/Swift/Transport/StreamBuffer.php
在263 行，就在$this->_stream = 之前，添加这两行：

$options['ssl']['verify_peer'] = FALSE;

$options['ssl']['verify_peer_name'] = FALSE;

代码现在应该如下所示：

[...]

$options = array();
if (!empty($this->_params['sourceIp'])) {
    $options['socket']['bindto'] = $this->_params['sourceIp'].':0';
}
$options['ssl']['verify_peer'] = FALSE;
$options['ssl']['verify_peer_name'] = FALSE;
$this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));

[...]

我希望这会有所帮助！

我的文件结构不是这样的。事实上，任何地方都没有 classes 文件夹，也没有 StreamBuffer.php 文件。这是 Prestashop 1.6 附带的 SwiftMailer 版本。

【解决方案2】：

我完全删除了 Prestashop 1.6.1 附带的 Swiftmailer 3.3.2 版本，并使用 composer 安装了最新版本。然后我修改了文件classes/Mail.php，如下所示。 diff 只包含修改后的行。
