Question

我有一个perl脚本可以做一些事情。如何在脚本完成任务后获取电子邮件，以及日志（执行脚本的所有操作）？

我打算从bash脚本调用perl脚本，然后让代码通过bash脚本发送日志。

但是我想知道还有其他更好的方法，我只能用单个脚本（perl）实现这一点，而不是有2个脚本，1个（perl脚本）用于执行任务，而其他（bash脚本）用于通过电子邮件发送日志中。

首先，您说您希望将STDOUT重定向到日志文件。查看以前的帖子了解详细信息：

How can I redirect standard output to a file in Perl?

# redirect STDOUT to file
my $log_file = "log.txt";
open STDOUT, '>', $log_file;

如果您使用LINUX，您应该能够发出sendmail命令以获取包含日志信息的电子邮件：

# define your to, from and subject.
my $to = <who you are sending email to>;
my $from = <who is it from>;
my $subject = "This is a subject";

# push the contents of your log file into the email body
open (LOG, '<', $log_file) or die "Failed to open $log_file: $!";
my @log_contents = <LOG>;
close LOG;

push @body, @log_contents;

# open and write to the mail file
open MAIL, '|/usr/sbin/sendmail -t' or die "Failed to send mail: $!";

# email header
print MAIL "To: ${to}\n";
print MAIL "From: ${from}\n";
print MAIL "Subject: ${subject}\n\n";

# email body
print MAIL @body;

# send the email
close MAIL;
print "Email sent successfully.\n";

这是一种快速发送信息的简单方法。

如果你在Windows上我会查看可用于在Perl中发送电子邮件的不同模块，例如MIME :: Lite

我曾经写过这个功能，它的效果非常好。

它需要在您的系统上安装MIME :: Lite模块 - 不确定这是否是一个绊脚石（它肯定在我的位置）

如果代码没有遵循最新标准，那么它是抱歉的，它大约有3年的历史，并且运行在Perl 5.6.1上我相信。

sub emailer($$$$$$;$);

use MIME::Lite;  


sub emailer($$$$$$;$)
{

    #-------------------------------------------------------------------------#
    # Get incoming parameters                                                 #
    #-------------------------------------------------------------------------#

    my ( $exchange_svr, $to, $cc, $from, $subject, $message, $attachment ) = @_;

    #-------------------------------------------------------------------------#
    # create a new message to be sent in HTML format                          #
    #-------------------------------------------------------------------------#

    my $msg = MIME::Lite->new(
                     From    => $from,
                     To      => $to,
                     Cc      => $cc,
                     Subject => $subject,
                     Type    => 'text/html',
                     Data    => $message
              );


    #-------------------------------------------------------------------------#
    # Check if there is an attachment and that the file actually does exist   #
    # Only plain text documents are supported in this functioN.               #
    #-------------------------------------------------------------------------#

    if ( $attachment )
    {

        #---------------------------------------------------------------------#
        # if the attachment does not exist then show a warning                #
        # The email will arrive with no attachment                            #
        #---------------------------------------------------------------------#

        if ( ! -f $attachment )
        {
            print "WARNING - Unable to locate $attachment";
        }
        else
        {
            #-----------------------------------------------------------------#
            # add the attachment                                              #
            #-----------------------------------------------------------------#

            print "ATTACH", "$attachment";

            $msg->attach(
                  Type => "text/plain",
                  Path => $attachment,
                  Disposition => "attachment"
            );
        }
    }

    #-------------------------------------------------------------------------#
    # send the email                                                          #
    #-------------------------------------------------------------------------#

    MIME::Lite->send( 'smtp', $exch_svr, Timeout => 20 );

    $msg->send() or die "SENDMAIL ERROR - Error sending email";

}

使用时看起来像这样

emailer( $exchange_server,
         "someone@somewhere.com",
         "someoneelse@somewhere.com",
         "me@mydesk.com",
         "Subject in here",
         "The Message in here",
         "/full/path/to/attachment" );

您可以选择添加第7个参数作为附件（您需要提供完整路径），附件必须是文本文件（我发送CSV文件）

修改

我刚刚重新阅读了您的帖子，发现您确实要发送附件，因此我将该部分添加到示例中
