Perl练习之验证身份证程序

近来对Perl有点兴趣，就写了个小程序，刚好有软工作业，于是分别用白黑盒测试了下，效果还是不错的！！！以后写网页表单验证可以用到。

说明下，身份证分一代证15位与二代证18位，其中前六位地区码，（这个没有验证）18位多的就是年份是四位，15位的年份两位，前两位默认为“19”，18位的最后一位为校验码，具体算法请看程序，其中前17位每一位都有权值，算出总和后模11算出对应的校验码即可。

更多说明请Google之。。。

其中带#标记的是用来标记白盒测试路径点，不知道是否合理，但是，一个正则表达式就搞定很多情况啊！！！

其中输入为，相信是看得懂的^_^

./cardValidate.pl -c [your id card number] -s [your sex]

#!/usr/bin/perl
use strict;
use Getopt::Long;

sub validate_birth{
    my ($year,$month,$day) = @_;
    if($year lt 1900 or $year gt 2011){#9 10
    	die "Bitrhday error year!n";
    }
    if($month eq "00" or $month gt 12){#11 12
    	die "Bitrhday error month!n";
    }
    my %days = (
            "01" => 31,"03" => 31,"04" => 30,"05" => 31,"06" => 30,"07" => 31,"08" => 31,"09" => 30,"10" => 31,"11" => 30,"12" => 31
            );
    if($year % 400 eq 0 or ($year % 4 eq 0 and $year % 100 ne 0)){#13 #14
        $days{"02"} = 28;        
    }else{#16
        $days{"02"} = 29;
    }
    if($days{$month} lt $day or $day eq "00"){#17 #18
        die "Bitrhday error date!n";
    }
    return 1;
}

###################        begin         ######################
our $code;
our $sex;

GetOptions("c=s" => $code,"s=s" => $sex);#1

if($code eq "" or $sex eq ""){#2 3
    print "Usage: ./cardValidate.pl -c [your id card number] -s [your sex]n";
    die "tNote: the length of your id number should be 15 or 18n";
}

our $code_len = length $code;#4

##################   basic rule and length   ##################
if($code !~ m/(^d{15}$)|(d{17}(d|x|X)$)/){#5
    die "Error code!n";
}

###################  birthday and sex  ######################
my $sex_num;
if($code_len eq 15){#6
    &validate_birth("19".substr($code,6,2),substr($code,8,10,2));#8
    $sex_num = substr($code,14,1) % 2; 
}elsif($code_len eq 18){#7
    &validate_birth(substr($code,4),12,16,1) % 2;
    
    #################  validate last character   ##################
    my @wight = (7,9,5,4,2,1,3,7,2);#权值
    my @validate = ('1','0','x','9','8','7','6','5','4','3','2');#对应的校验码
    my $sum = 0;
    for(my $i = 0;$i < 17;$i++){
        $sum += @wight[$i] * substr($code,$i,1);
    }
    if(@validate[$sum % 11] ne lc substr($code,17,1)){#19
        die "Error while validate the last character!,it should be ".@validate[$sum % 11]."n";
    }
}

#################        sex           ######################
if(($sex_num eq 1 and $sex eq "女") or ($sex_num eq 0 and $sex eq "男")){#20 21
    die "Wrong sex number!n";
}

print "Success!n";#22

然后是用来测试的程序：

将身份证号码与0表示女，1表示男输入到文件中，比如：”7837838484884 0“ 就可以

每行一条数据，然后将文件名当作参数传入即可，当然，上面的程序需要放在同目录下。于是白黑盒测试的数据可以放一起全部测试

#!/usr/bin/perl
use strict;

open FILE,"< ",$ARGV[0] or die "id file not exist!n";
my @lines = <FILE>;
foreach(@lines){
    if(~/^([wd]+) (d)/){
        my $sex = ($2 eq 0?"女":"男");
        print "Test $1 with sex $sexn";
        system("./cardValidate.pl -c $1 -s $sex");
        print "n";
    }
}
