具有特殊字符的 CSR 主题摘录

CSR Subject with Special Characters extract

我需要提取 $subj,如下面的代码片段所示,但看起来我的 Regex 没有按预期工作。这实际上与此类似: 但 CSR 中的主题条目不同。我不确定我是否在 %subjinfo

的正则表达式中做了一件好事
#!/usr/bin/env perl
use strict;
use warnings;
use Data::Dumper;

my $subj =
    'subject=/O=test~@#$^()_+-=\{}|;':",./<>/OU=test~@#$^()_+-=\{}|;':",./<>/emailAd‌​dress=test~@#$^()_+-=\{}|;':",./<>/L=CDE/ST=ABC/C=AU/CN=test~@#$^()_+ -=\{}|;':",./<>';

my %subjinfo = ( $subj =~ m,(\w+)=([^=]*)(?:/|$),g );
print Dumper \%subjinfo;

因此必须给出结果:

$VAR1 = {
          'subject' => '',
          'L' => 'NYC',
          'C' => 'AMER',
          'OU' => 'test~@#$^()_+-=\{}|;':",./<>',
          'emailAddress' => 'test~@#$^()_+-=\{}|;':",./<>',
          'ST' => 'AMER',
          'CN' => 'test~@#$^()_+-=\{}|;':",./<>',
          'O' => 'test~@#$^()_+-=\{}|;':",./<>'
        };

这可能吗?你能建议一下吗?

拆分正则表达式看起来比仅使用正则表达式的解决方案更自然,

use Data::Dumper;

my $subj = q(subject=/O=test~@#$^()_+-=\{}|;':",./<>/OU=test~@#$^()_+-=\{}|;':",./<>/emailAddress=test~@#$^()_+-=\{}|;':",./<>/L=CDE/ST=ABC/C=AU/CN=test~@#$^()_+ -=\{}|;':",./<>);

(undef, my %subjinfo) = split m|/?(\w+)=|, $subj;

print Dumper \%subjinfo;

输出

$VAR1 = {
      'emailAddress' => 'test~@#$^()_+-=\{}|;\':",./<>',
      'CN' => 'test~@#$^()_+ -=\{}|;\':",./<>',
      'OU' => 'test~@#$^()_+-=\{}|;\':",./<>',
      'L' => 'CDE',
      'C' => 'AU',
      'ST' => 'ABC',
      'subject' => '',
      'O' => 'test~@#$^()_+-=\{}|;\':",./<>'
    };
