使用Bugzilla,你肯定會遇到的坑。

bugzilla smtp ssl mail perl


最近和幾個朋友一起做用戶態協議棧開源項目 NtyTcp ,純業余愛好,個人情懷。剛剛開始做有好多的Bug,故搭建了一個Bugzilla,用來上傳Bug的。

有幾個開發朋友想在 bug.ntytcp.com提交bug,不能註冊,因為不能發郵件。至於為什麽不能發送郵件?因為阿裏雲把25端口封了,使用smtp不能發送。

使用465端口發送,發現發不出來,又找不到原因。硬著頭皮比Bugzilla的源碼看了一下。可恨的是自己並沒有寫過perl代碼。


於是用了兩天時間連學帶看就把bugzilla的源碼看了一遍。然後把bugzilla郵件發送的部分重寫了一下。先把bugzilla郵件發送部分貼出來。

bugzilla/mailer.pm

sub MessageToMTA {
my ($msg, $send_now) = (@_);
my $method = Bugzilla->params->{'mail_delivery_method'};
return if $method eq 'None';

if (Bugzilla->params->{'use_mailer_queue'}
&& ! $send_now
&& ! Bugzilla->dbh->bz_in_transaction()
) {
Bugzilla->job_queue->insert('send_mail', { msg => $msg });
return;
}

my $dbh = Bugzilla->dbh;

my $email = ref($msg) ? $msg : Bugzilla::MIME->new($msg);

# If we're called from within a transaction, we don't want to send the
# email immediately, in case the transaction is rolled back. Instead we
# insert it into the mail_staging table, and bz_commit_transaction calls
# send_staged_mail() after the transaction is committed.
if (! $send_now && $dbh->bz_in_transaction()) {
# The e-mail string may contain tainted values.
my $string = $email->as_string;
trick_taint($string);

my $sth = $dbh->prepare("INSERT INTO mail_staging (message) VALUES (?)");
$sth->bind_param(1, $string, $dbh->BLOB_TYPE);
$sth->execute;
return;
}

my $from = $email->header('From');

my $hostname;
my $transport;
if ($method eq "Sendmail") {
if (ON_WINDOWS) {
$transport = Bugzilla::Sender::Transport::Sendmail->new({ sendmail => SENDMAIL_EXE });
}
else {
$transport = Bugzilla::Sender::Transport::Sendmail->new();
}
}
else {
# Sendmail will automatically append our hostname to the From
# address, but other mailers won't.
my $urlbase = Bugzilla->params->{'urlbase'};
$urlbase =~ m|//([^:/]+)[:/]?|;
$hostname = $1 || 'localhost';
$from .= "\@$hostname" if $from !~ /@/;
$email->header_set('From', $from);
# Sendmail adds a Date: header also, but others may not.
if (!defined $email->header('Date')) {
$email->header_set('Date', time2str("%a, %d %b %Y %T %z", time()));
}
}

if ($method eq "SMTP") {
my ($host, $port) = split(/:/, Bugzilla->params->{'smtpserver'}, 2);
$transport = Bugzilla->request_cache->{smtp} //=
Email::Sender::Transport::SMTP::Persistent->new({
host  => $host,
defined($port) ? (port => $port) : (),
sasl_username => Bugzilla->params->{'smtp_username'},
sasl_password => Bugzilla->params->{'smtp_password'},
helo => $hostname,
ssl => Bugzilla->params->{'smtp_ssl'},
debug => Bugzilla->params->{'smtp_debug'} });
}

Bugzilla::Hook::process('mailer_before_send', { email => $email });

return if $email->header('to') eq '';

if ($method eq "Test") {
my $filename = bz_locations()->{'datadir'} . '/mailer.testfile';
open TESTFILE, '>>', $filename;
# From - <date> is required to be a valid mbox file.
print TESTFILE "\n\nFrom - " . $email->header('Date') . "\n" . $email->as_string;
close TESTFILE;
}
else {
# This is useful for Sendmail, so we put it out here.
local $ENV{PATH} = SENDMAIL_PATH;
eval { sendmail($email, { transport => $transport }) };
if ($@) {
ThrowCodeError('mail_send_error', { msg => $@->message, mail => $email });
}
}
}


使用的sendmail($email, {transport=> $transport}), 發送。由於系統的sendmail沒有配置好,發送不出來。

自己寫了一版單獨用perl發送郵件的。

#!/usr/bin/perl

use Net::SMTP::SSL;
use MIME::Base64;
use MIME::Lite;

my $msg = MIME::Lite->new(
From=>'[email protected]',
To=>'[email protected]',
Subject=>'First Email',
Data=>'nihao',
Type=>'text/html'
);

$account="[email protected]";
$password="your password";
$smtp = Net::SMTP::SSL->new(
Host => 'smtp.host.com',
Port => 465,
Timeout => 120,
Debug=>1
); # connect to an SMTP server
die "Couldn't open connection: $!" if (!defined $smtp );
#$smtp->auth($account,$password);

$smtp->datasend("AUTH LOGIN\r\n");
$smtp->datasend(encode_base64('[email protected]')); # username
$smtp->datasend(encode_base64('your password')); # password

$smtp->mail('[email protected]');
$smtp->to('[email protected]');

$smtp->data();

$smtp->datasend($msg->as_string());

$smtp->datasend("Blah\r\n\r\n");

$smtp->dataend();


相信從代碼風格來看,就是第一次寫perl 。^_^ 。 ^_^

這版是可以發送郵件的。

但是跟bugzilla的mailer.pm 發送差別很大。沒辦法整合。


於是又換了一種寫法。

#!/usr/bin/perl

use strict;
use warnings;

use Email::Sender::Simple qw(sendmail);
use Email::Sender::Transport::SMTP ();
use Email::Simple ();
use Email::Simple::Creator ();
use Email::Sender::Transport::SMTP::TLS;
use Email::Sender::Transport::SMTP::Persistent;
use Email::Sender::Transport::SMTPS;
use Net::SMTP::SSL;
use MIME::Base64;

my $smtpserver   = 'smtp.host.com';
my $smtpport     = 465;
my $smtpuser     = '[email protected]';
my $smtppassword = 'your password';
my $smtpto       = '[email protected]';
my $hostname     = 'localhost.localdomain';

my $transport = Email::Sender::Transport::SMTP::Persistent->new({
            host  => $smtpserver,
            defined($smtpport) ? (port => $smtpport) : (),
            sasl_username => $smtpuser,
            sasl_password => $smtpuser,
            helo => $hostname,
            ssl => 1,
            debug => 1 });

my $email = Email::Simple->create(
  header => [
    To      => $smtpto,
    From    => $smtpuser,
    Subject => 'Hi!',
  ],
  body => "This is my message\n",
);

#try {
#eval {sendmail($email, { transport => $transport }) };
#}catch {
#die "Error sending email: $_";
my $smtp = Net::SMTP::SSL->new(
            Host  => $smtpserver,
            Port => $smtpport,
            Timeout => 120,
            Debug => 1
        );
        die "Couldn't open connection: $!" if (!defined $smtp );

        #$smtp->auth(Bugzilla->params->{'smtp_username'}, Bugzilla->params->{'smtp_password'});
        $smtp->datasend("AUTH LOGIN\n");
        $smtp->datasend(encode_base64($smtpuser));
        $smtp->datasend(encode_base64($smtppassword));

        $smtp->mail($smtpuser);
        $smtp->to($smtpto);

        $smtp->data();
        $smtp->datasend($email->as_string());

        $smtp->datasend("\r\n\r\n");
        $smtp->dataend();
        $smtp->quit();


這個代碼的風格就像那麽回事了,就寫過perl代碼的人了 。^_^。^_^

將mailer.pm 的代碼整合。

sub MessageToMTA {
    my ($msg, $send_now) = (@_);
    my $method = Bugzilla->params->{'mail_delivery_method'};
    return if $method eq 'None';

    if (Bugzilla->params->{'use_mailer_queue'}
        && ! $send_now
        && ! Bugzilla->dbh->bz_in_transaction()
    ) {
        Bugzilla->job_queue->insert('send_mail', { msg => $msg });
        return;
    }

    my $dbh = Bugzilla->dbh;

    my $email = ref($msg) ? $msg : Bugzilla::MIME->new($msg);

    # If we're called from within a transaction, we don't want to send the
    # email immediately, in case the transaction is rolled back. Instead we
    # insert it into the mail_staging table, and bz_commit_transaction calls
    # send_staged_mail() after the transaction is committed.
    if (! $send_now && $dbh->bz_in_transaction()) {
        # The e-mail string may contain tainted values.
        my $string = $email->as_string;
        trick_taint($string);

        my $sth = $dbh->prepare("INSERT INTO mail_staging (message) VALUES (?)");
        $sth->bind_param(1, $string, $dbh->BLOB_TYPE);
        $sth->execute;
        return;
    }

    my $from = $email->header('From');

    my $hostname;
    my $transport;
    if ($method eq "Sendmail") {
        if (ON_WINDOWS) {
            $transport = Bugzilla::Sender::Transport::Sendmail->new({ sendmail => SENDMAIL_EXE });
        }
        else {
            $transport = Bugzilla::Sender::Transport::Sendmail->new();
        }
    }
    else {
        # Sendmail will automatically append our hostname to the From
        # address, but other mailers won't.
        my $urlbase = Bugzilla->params->{'urlbase'};
        $urlbase =~ m|//([^:/]+)[:/]?|;
        $hostname = $1 || 'localhost';
        $from .= "\@$hostname" if $from !~ /@/;
        $email->header_set('From', $from);

        # Sendmail adds a Date: header also, but others may not.
        if (!defined $email->header('Date')) {
            $email->header_set('Date', time2str("%a, %d %b %Y %T %z", time()));
        }
    }
    my ($host, $port) = split(/:/, Bugzilla->params->{'smtpserver'}, 2);
    if ($method eq "SMTP") {
#        my ($host, $port) = split(/:/, Bugzilla->params->{'smtpserver'}, 2);
        $transport = Bugzilla->request_cache->{smtp} //=
          Email::Sender::Transport::SMTP::Persistent->new({
            host  => $host,
            defined($port) ? (port => $port) : (),
            sasl_username => Bugzilla->params->{'smtp_username'},
            sasl_password => Bugzilla->params->{'smtp_password'},
            helo => $hostname,
            ssl => Bugzilla->params->{'smtp_ssl'},
            debug => Bugzilla->params->{'smtp_debug'} });

    }

    Bugzilla::Hook::process('mailer_before_send', { email => $email });

    return if $email->header('to') eq '';

    if ($method eq "Test") {
        my $filename = bz_locations()->{'datadir'} . '/mailer.testfile';
        open TESTFILE, '>>', $filename;
        # From - <date> is required to be a valid mbox file.
        print TESTFILE "\n\nFrom - " . $email->header('Date') . "\n" . $email->as_string;
        close TESTFILE;
    }
    else {
        # This is useful for Sendmail, so we put it out here.
#        local $ENV{PATH} = SENDMAIL_PATH;
#        eval { sendmail($email, { transport => $transport }) };
#        if ($@) {
#            ThrowCodeError('mail_send_error', { msg => $@->message, mail => $email });
#        }
        my $smtp = Net::SMTP::SSL->new(
            Host  => $host,
            Port => $port,
            Timeout => 120,
            Debug => 1
        );
        die "Couldn't open connection: $!" if (!defined $smtp );

        #$smtp->auth(Bugzilla->params->{'smtp_username'}, Bugzilla->params->{'smtp_password'});
        $smtp->datasend("AUTH LOGIN\n");
        $smtp->datasend(encode_base64(Bugzilla->params->{'smtp_username'}));
        $smtp->datasend(encode_base64(Bugzilla->params->{'smtp_password'}));

        $smtp->mail(Bugzilla->params->{'smtp_username'});
        $smtp->to($email->header('to'));

        $smtp->data();
        $smtp->datasend($email->as_string());

        $smtp->datasend("\r\n\r\n");
        $smtp->dataend();
        $smtp->quit();
    }
}


主要是將郵件發送方式修改了。

        local $ENV{PATH} = SENDMAIL_PATH;
        eval { sendmail($email, { transport => $transport }) };
        if ($@) {
            ThrowCodeError('mail_send_error', { msg => $@->message, mail => $email });
        }

換成了

        my $smtp = Net::SMTP::SSL->new(
            Host  => $host,
            Port => $port,
            Timeout => 120,
            Debug => 1
        );
        die "Couldn't open connection: $!" if (!defined $smtp );

        #$smtp->auth(Bugzilla->params->{'smtp_username'}, Bugzilla->params->{'smtp_password'});
        $smtp->datasend("AUTH LOGIN\n");
        $smtp->datasend(encode_base64(Bugzilla->params->{'smtp_username'}));
        $smtp->datasend(encode_base64(Bugzilla->params->{'smtp_password'}));

        $smtp->mail(Bugzilla->params->{'smtp_username'});
        $smtp->to($email->header('to'));

        $smtp->data();
        $smtp->datasend($email->as_string());

        $smtp->datasend("\r\n\r\n");
        $smtp->dataend();
        $smtp->quit();


bugzilla的代碼還是寫的很人性化的,沒有寫過perl代碼的,一看都能知道個大概。向Bugzilla的作者致敬。

至於郵件發送的流程,大家可以參照rfc822,不要隨便相信網上的代碼。



使用Bugzilla,你肯定會遇到的坑。
