如何通过Email :: Simple发送电子邮件？

Question

我想发送电子邮件。我的Email::Simple（模块版本2.216）对象是：

Email::Simple {
  body => \## EXCEPTION MESSAGE
RU Error message: Какой-то текст‚ at /home/kes/work/projects/tucha/monkeyman/lib/MaitreD.pm line 75.
,
  header => Email::Simple::Header {
    headers => [
      To,
      [
        to@domain,
        To: to@domain,
      ],
      From,
      [
        from@domain,
        From: from@domain,
      ],
      Subject,
      [
        Exception,
        Subject: Exception,
      ],
      Content-Type,
      [
        text/plain; charset="utf8",
        Content-Type: text/plain; charset="utf8",
      ],
      Date,
      Wed, 26 Feb 2020 14:30:39 +0200,
    ],
    mycrlf => 
,
  },
  mycrlf => 
,
}

这里通讯中断了。我这一边正在等待邮件服务器，邮件服务器正在等待我这边的东西。然后服务器超时断开连接

/home/kes/work/projects/tucha/monkeyman/local/lib/perl5/Email/Sender/Transport/SMTP.pm
    300:     # -- rjbs, 2015-08-10
    301:     utf8::downgrade($next_hunk) if (0+Net::SMTP->VERSION || 0) < 3.07;
    302:
   x303:     warn "H1\n";
   x304:     $smtp->datasend($next_hunk) or $FAULT->("error at during DATA");
   x305:     warn "H2\n";
    306:   }
    307:
   x308:   warn "H3\n";
   x309:   DB::x;
  >>310:   $smtp->dataend                     or $FAULT->("error at after DATA");

如何通过Email::Simple正确发送utf8文本？

我的代码：

    my $email =  Email::Simple->create(
        header =>  [
            To             =>  $address,
            From           =>  $cnf->{ from },
            Subject        =>  $subject,
            %$headers,
        ],
        body => $body,
    );
    my $err =  Email::Sender::Simple->send( $email, { transport => $transport } );

UPD邮件正文为：

Devel::Peek::Dump( $body )
SV = IV(0xc3ff920) at 0xc3ff930
  REFCNT = 2
  FLAGS = (ROK)
  RV = 0x10d0d530
  SV = PVMG(0x10d36f60) at 0x10d0d530
    REFCNT = 3
    FLAGS = (OBJECT,POK,IsCOW,pPOK,UTF8)
    IV = 0
    NV = 0
    PV = 0x10d69cd0 "## EXCEPTION MESSAGE\nRU Error message: \320\232\320\260\320\272\320\276\320\271-\321\202\320\276 \321\202\320\265\320\272\321\201\321\202 at /home/kes/work/projects/tucha/monkeyman/lib/MaitreD.pm line 75.\n\n"\0 [UTF8 "## EXCEPTION MESSAGE\nRU Error message: \x{41a}\x{430}\x{43a}\x{43e}\x{439}-\x{442}\x{43e} \x{442}\x{435}\x{43a}\x{441}\x{442} at /home/kes/work/projects/tucha/monkeyman/lib/MaitreD.pm line 75.\n\n"]
    CUR = 134
    LEN = 136
    COW_REFCNT = 1
    STASH = 0x35583d0   "Mojo::ByteStream"

当我Encode::decode( 'utf8', $body )出现错误：

Wide character at ...

当我Encode::encode( 'utf8', $body )时

Devel::Peek::Dump( $body )
SV = PVIV(0x10c77a18) at 0xc3ff930
  REFCNT = 2
  FLAGS = (POK,IsCOW,pPOK)
  IV = 0
  PV = 0x10df0750 "## EXCEPTION MESSAGE\nRU Error message: \320\232\320\260\320\272\320\276\320\271-\321\202\320\276 \321\202\320\265\320\272\321\201\321\202 at /home/kes/work/projects/tucha/monkeyman/lib/MaitreD.pm line 75.\n\n"\0
  CUR = 134
  LEN = 136
  COW_REFCNT = 0

并发送

然后一切都很好：

Net::SMTP::_SSL=GLOB(0x10e280e8)>>> .
Net::SMTP::_SSL=GLOB(0x10e280e8)<<< 250 2.0.0 Ok: queued as D83FF102BA8

Answer 1

谢谢@ smonff。正文应在发送之前进行编码：

$body =  Encode::encode( utf8 => $body )

现在我可以发送utf8电子邮件：

my $email =  Email::Simple->create(
    header =>  [
        To             =>  $address,
        From           =>  $cnf->{ from },
        Subject        =>  $subject,
        %$headers,
    ],
    body => $body,
);
my $err =  Email::Sender::Simple->send( $email, { transport => $transport } );
