Question

是否可以通过PHPmailer为代码添加/更新边界标题

$mail->addStringAttachment($test, 'test.txt', 'quoted-printable');

我需要添加/更新

--b1_KyZbvbrSl55hdWoQf7uUOwdfF2oGjqnCyP6rqNmlA
Content-Type: text/plain; name="test.txt"
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; filename=test.txt

看起来像

--b1_KyZbvbrSl55hdWoQf7uUOwdfF2oGjqnCyP6rqNmlA
Content-Type: text/plain; name="test.txt"; charset=utf-8
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; filename=test.txt
Content-ID: 20cca107-2625-49ce-9357-95254a59147f@127.0.0.1

所以为Content-Type标题添加了charset参数，然后添加了新标题Content-ID

有关于此的任何提示吗？

Answer 1

经过进一步调查后，它出现了

addStringEmbeddedImage方法允许您为其设置cid 附件将为您设置标题。你可以忽略＆＃34;图像＆＃34;在方法名称中 - 它并不关心您的内容类型真的附上。

所以在我的情况下它将是

$mail->addStringEmbeddedImage(file_get_contents($file_name, FILE_USE_INCLUDE_PATH), $uuid, $file_name, 'base64', '', 'attachment');

关于将charset参数添加到Content-Type边界标题

quoted-printable transfer encoding是ASCII 7bit安全的，所以默认将工作正常，它不需要额外的charset条款。

对于transfer-encoding和charset

'mysql' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST', 'localhost'),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ],
'sqlsrv' => [
        'sqlsrv_Org' => [
            'driver'   => 'sqlsrv',
            'host'     => env('DB_HOST'),
            'port'     => null,//sqlsrv no port
            'database' => env('DB_DATABASE2'),
            'username' => env('DB_USERNAME2'),
            'password' => env('DB_PASSWORD2'),
            'charset'  => 'utf8',
            'prefix'   => '',
        ],

对于content-id，请检查addEmbeddedImage方法或尝试直接添加标题：

$mail->Encoding = 'quoted-printable';
$mail->CharSet = 'UTF-8';
