用 Perl 生成随机密码 - Win32::GUI 版

时间：2009-03-28 来源：cobrawgl

用 perl 生成随机密码是很简单的，只要几行 code 就可以了，这里主要是加上了 GUI 界面，并且用了新的 Coding Style :) 本来还想用 Moose 的，一犯懒就没动，以后试试。 perl 传递函数的方式让我很不爽，不知道 perl6 里会怎么样。。。

use strict;
use warnings;

Class_Main: {
    MyApp->new->run;
}

Class_MyApp: {
    package MyApp;
    use Win32::GUI qw( MB_ICONINFORMATION MB_OK );;

    sub new {
        my $class = shift;
        my $self = {@_};

        bless $self, $class;

        $self->interface;

        return $self;
    }

    sub run {
        my $self = shift;

        $self->{win}->Show();
        Win32::GUI::Dialog();

    }

    sub display_password {
        my $self = shift;

        use String::MkPasswd qw(mkpasswd);

        my $passwd = mkpasswd(
            -length => 9,
            -minnum => 2,
            -minlower => 2, # minlower is increased if necessary

            -minupper => 2,
            -minspecial => 2,
            -distribute => 1,
        );

        $self->{win}->MessageBox(
            $passwd,
            "您的密码",
         MB_ICONINFORMATION | MB_OK,
        );
    }

    sub display_help {
        my $self = shift;

        my $message = "密码长度：您需要的密码位数。默认是9位。\r\n" .
                    "数字个数：您的密码中最少有几个数字。默认最少2个。\r\n" .
                    "小写字母：您的密码中最少有几个小写字母。默认最少2个。\r\n" .
                    "大写字母：您的密码中最少有几个大写字母。默认最少2个。\r\n" .
