Perl Net::SMTP::TLS attach file

用 $smtp->datasend 傳附檔內容時，因為 gmail 接收資料有長度限制，如果一次傳送大量資料會出錯。變通辦法是用 split 將資料分段送出。


use Net::SMTP::TLS;
use MIME::Lite;

$gmail_from = 'account@gmail.com';
@gmail_bcc_png = ('bcc@gmail.com');
$mail_subject = "<mail_subjuct>";

$msg = MIME::Lite->new(
From       => $gmail_from,
    To         => $gmail_from,
    Subject    => $mail_subject,
Type     =>'multipart/mixed',
);
$msg->attach(
Type => 'image/png',
Path => '<file full path>',
Filename => 'report1.png',
Disposition => 'attachment'
);

$smtp = new Net::SMTP::TLS(
'smtp.gmail.com',
Port    => 587,
User    => '<account@gmail.com>',
Password=> '<password>',
Timeout => 30
);

$smtp->mail($gmail_from);

$smtp->bcc(@gmail_bcc_png);

$smtp->data();
  @tmp = split(/\n/, $msg->as_string);
foreach $line (@tmp) {
$line = $line . "\n";
$smtp->datasend( $line );
}
$smtp->dataend();

$smtp->quit;
