Question

我使用Perl和Email :: MIME通过IMAP访问电子邮件帐户。当我尝试下载附件时，我收到此错误：

无效的内容类型＆＃39; multipart /; 边界=＆＃34; =============== 6113972194662902815 ==＆＃34;＆＃39;在 /path/to/class/Reader.pm第99行。

这是我的代码：

my $env = $self->env();
my $imap = $self->imap();
my $logger = $self->logger();

my ($OUT, $out_file);

# parse attachment
my $message_string = $imap->message_string($imap_id);

Email::MIME->new($message_string)->walk_parts(sub {

    my ($part) = @_;

    if ($part->content_type =~ /octet\-stream/) {
        ($OUT, $out_file) = tempfile();
        binmode $OUT;

        print $OUT $part->body;
        close $OUT;

        $logger->info("downloaded attached report: [$out_file]");
    }

});

这是$ part转储的结束：

我尝试了几种不同的下载此文件的方法，但我一直收到该错误。如果有任何问题，请告诉我
