Mailgun发送带附件的邮件

Question

我正在尝试使用mailgun发送带附件的邮件.邮件本身很好,但它缺少附件.同样在mailgun日志中,它显示正常,但附件数组为空.

我用example.com替换了我的凭证.该文件放在子目录中并且可读.

$filename = 'directory/example.pdf';
$parameters = array('from' => 'Example <example@mail.example.com>',
                    'to' => 'example@example.com',
                    'subject' => 'Subject',
                    'text' => 'This is just a test.',
                    'attachment[1]' => '@' . $filename);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.mailgun.net/v3/mail.example.com/messages');
curl_setopt($ch, CURLOPT_USERPWD, 'api:key-ThisIsJustARandomString');

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

我没有收到错误,这是$response:

string(103) "{
    "id": "<20170514122638.8820.55203.4543B111@mail.example.com>",
    "message": "Queued. Thank you."
}"

在mailgun日志中没有列出附件:

"message": {
    "headers": {
        "to": "example@example.com",
        "message-id": "20170514122638.8820.55203.4543B111@mail.example.com",
        "from": "Example <example@mail.example.com>",
        "subject": "Subject"
    },
    "attachments": [],
    "size": 349
},

根据所有文档,我发现这将是正确的解决方案,但它不起作用.

提前感谢所有回复.

将您的第一个代码更改为:

$filename = 'directory/example.pdf';
$parameters = array('from' => 'Example <example@mail.example.com>',
                'to' => 'example@example.com',
                'subject' => 'Subject',
                'text' => 'This is just a test.',
                'attachment[1]' => curl_file_create($filename, 'application/pdf', 'example.pdf'));

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.mailgun.net/v3/mail.example.com/messages');
curl_setopt($ch, CURLOPT_USERPWD, 'api:key-ThisIsJustARandomString');

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

我换'@'.$filename了curl_file_create($filename, 'application/pdf', 'example.pdf').

请参阅文档curl_file_create并查看PHP <5.5的注释.
