[Perl][Mail]关于邮件的几个模块

这几天净捣鼓收取邮件的问题了,一开始用了些基本的模块,很多问题解决不了,查找了文档才有点眉目.

先说说环境:
Cygwin+Perl5.8+Mail::POP3Client+MIME::Parser+MIME::Entity+Time::HiRes

Mail::POP3Client  封装了基本的Net::POP3,使用起来更简单

MIME::Parser是MIME::Entity的子类,就是用来解析格式的

Time::HiRes用来计算消耗时间

看看代码:
===========================================================================
#!/usr/bin/perl -w
use strict;

use Mail::POP3Client;
use Time::HiRes qw(gettimeofday tv_interval);
use MIME::Parser;
use MIME::Entity;

my $start_time = [gettimeofday];

my $host   = 'pop3.163.com';
my $user   = '####@163.com';
my $passwd = '******';

my $client = new Mail::POP3Client( $user, $passwd, $host );
my $parser = MIME::Parser->new;
my $mgrnum = $client->Count;

print "当前共有邮件[$mgrnum]封!/n";

for ( my $i = 1 ; $i <= $mgrnum ; $i++ ) {
    my $headandbody = $client->HeadAndBody($i);
    my $entity = $parser->parse_data($headandbody);

    $parser->decode_headers(1);
    print "From      = ",$entity->head->get('From');
    print "To        = ",$entity->head->get('To');
    print "Cc        = ",$entity->head->get('Cc');
    print "Subject   = ",$entity->head->get('Subject');
    print "MIME type = ",$entity->mime_type,"/n";
    print "Parts     = ",scalar $entity->parts,"/n";
    my $part_num = scalar $entity->parts;
    for my $part ($entity->parts){
        print "/t",$part->mime_type,"/t",$part->bodyhandle,"/n";
    }

    print "=========================================================/n";
   
    exit if ( (scalar $entity->parts) == 1 );
    #exit if ($i >= 3);
}

my $interval = tv_interval( $start_time, [gettimeofday] );
print "it take the time : $interval seconds/n";
==============================================================================

前面始终没有闹明白为什么邮件头里面Subjects中文总是乱码不能解析,翻了翻RFC的文档,看看MIMR::Parser才知道有一个decode函数

    ### Automatically attempt to RFC 2047-decode the MIME headers?
    $parser->decode_headers(1);             ### default is false

解析还是很方便的,呵呵

在$parser->parse_data($headandbody)的时候会将邮件body保留在本地msg-PID-#.txt文件中,附件也保留在相应目录下!
