php-使用SwiftMailer为text / html和text / plain使用附件

2019-10-26 16:31:16 作者：互联网

我正在使用swiftmailer
发送电子邮件,我希望拥有相同的附件：
* HTML版本(text / html)作为内嵌图片(cid)
*文本版本(文本/纯文本)作为附件

我正在Ubuntu上使用Mozilla Thunderbird 45.3.0测试电子邮件.

我一直在玩-> setBody,-> addPart,-> embed和-> attach方法,
但我总是破坏其中一个版本(即以纯文本格式接收电子邮件,或者将消息视为HTML或Text格式).

我的测试代码看起来像(当然带有有效的SMTP地址和文件路径)：

function swiftMail() {
    require_once './vendor/swiftmailer/swiftmailer/lib/swift_required.php';
    //Create the Transport
    $transport = Swift_SmtpTransport::newInstance('smtp.mail.com', 25);
    //Create the Mailer using your created Transport
    $mailer = Swift_Mailer::newInstance($transport);
    // Create the message
    $message = Swift_Message::newInstance()
        // Give the message a subject
        ->setSubject('SwiftMailer test // ' . uniqid('', true))
        // Set the From address with an associative array
        ->setFrom(array('first.name@mail.com' => 'Me'))
        // Set the To addresses with an associative array
        ->setTo(array('first.name@mail.com' => 'Me'));

    // attach the image as attachment
    $message->attach(Swift_Attachment::fromPath('./path/to/file.png')->setFilename('cool_image.png'));

    // set the email's body as plain text
    $message->setBody('My amazing body in plain text', 'text/plain');

    // add the email's HTML part to the message
    $message->addPart(
        '<!doctype html>' .
        '<html>' .
        ' <head><meta charset="UTF-8"></head>' .
        ' <body>' .
        '  Here is an image <br />'.
        '  <img src="' . $message->embed(Swift_Image::fromPath('./path/to/file.png')->setFilename('inline_cool_image.png')) . '" alt="Inline Image" /><br />' .
        '  Rest of message' .
        ' </body>' .
        '</html>',
        'text/html' // Mark the content-type as HTML
    );

    // send the message
    if (!$mailer->send($message, $failures))
    {
        echo "Failures:";
        print_r($failures);
    }
}

以下代码产生两个附件(可能很好),只有纯文本版本可用(这不好).

有没有办法将附件用作嵌入式HTML图像源和纯文本电子邮件中的标准附件？

解决方法:

我遇到了完全相同的问题,并且能够通过使用addPart()而非setBody()添加纯文本部分来解决此问题.

$message->addPart('My amazing body in plain text', 'text/plain');

根据您的示例,它将是：

function swiftMail() {
    require_once './vendor/swiftmailer/swiftmailer/lib/swift_required.php';
    //Create the Transport
    $transport = Swift_SmtpTransport::newInstance('smtp.mail.com', 25);
    //Create the Mailer using your created Transport
    $mailer = Swift_Mailer::newInstance($transport);
    // Create the message
    $message = Swift_Message::newInstance()
        // Give the message a subject
        ->setSubject('SwiftMailer test // ' . uniqid('', true))
        // Set the From address with an associative array
        ->setFrom(array('first.name@mail.com' => 'Me'))
        // Set the To addresses with an associative array
        ->setTo(array('first.name@mail.com' => 'Me'));

    // attach the image as attachment
    $message->attach(Swift_Attachment::fromPath('./path/to/file.png')->setFilename('cool_image.png'));

    // set the email's body as plain text
    $message->addPart('My amazing body in plain text', 'text/plain');

    // add the email's HTML part to the message
    $message->addPart(
        '<!doctype html>' .
        '<html>' .
        ' <head><meta charset="UTF-8"></head>' .
        ' <body>' .
        '  Here is an image <br />'.
        '  <img src="' . $message->embed(Swift_Image::fromPath('./path/to/file.png')->setFilename('inline_cool_image.png')) . '" alt="Inline Image" /><br />' .
        '  Rest of message' .
        ' </body>' .
        '</html>',
        'text/html' // Mark the content-type as HTML
    );

    // send the message
    if (!$mailer->send($message, $failures))
    {
        echo "Failures:";
        print_r($failures);
    }
}

已在macOS和Gmail网络界面上使用SwiftMailer版本5.4.4,Thunderbird 45.5.0进行了测试.
