Perl:访问和处理数组中的对象

Question

我尝试处理由get_pool_member_object_status_($pool)生成的以下数组

来自($pool)

$VAR1 = [
      [
        bless( [
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.141',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' ),
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.142',

                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' ),
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.143',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' ),
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.144',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' )
               ], 'LocalLB::PoolMember::MemberObjectStatus[]' )
      ]
    ];

我不知道该怎么做。我试过了perldsc的几个例子。其中的例子主要涉及哈希数组。但上面的数组是.？我甚至不知道这是什么阵列。有人能给我指明正确的方向吗？

因此，例如，如何访问"object_status"->"availability_status"的"member"->"address"

辛巴伯。这是我从Data::Printer:获得的输出

[
[0] [
    [0] LocalLB::PoolMember::MemberObjectStatus[]  {
        public methods (0)
        private methods (0)
        internals: [
            [0] LocalLB::PoolMember::MemberObjectStatus,
            [1] LocalLB::PoolMember::MemberObjectStatus,
            [2] LocalLB::PoolMember::MemberObjectStatus,
            [3] LocalLB::PoolMember::MemberObjectStatus
        ]
    }
]

]

Answer 1

所以您正在尝试访问'availability_status'和'address'。

我没有遍历整个对象，但是有了这些代码，我就能够打印所需的字段。

#!/usr/bin/perl -w
use strict;
use warnings;
use Data::Dumper;


my $obj = [
      [
        bless( [
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.141',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' ),
                 bless( {

                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.143',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' ),
                 bless( {
                          'member' => bless( {
                                             'address' => '192.168.100.144',
                                             'port' => '80'
                                           }, 'Common::IPPortDefinition' ),
                          'object_status' => bless( {
                                                    'availability_status' => 'AVAILABILITY_STATUS_GREEN',
                                                    'status_description' => 'Pool member is available',
                                                    'enabled_status' => 'ENABLED_STATUS_ENABLED'
                                                  }, 'LocalLB::ObjectStatus' )
                        }, 'LocalLB::PoolMember::MemberObjectStatus' )
               ], 'LocalLB::PoolMember::MemberObjectStatus[]' )
      ]
    ];

print Dumper($obj->[0]->[0]->[0]->{member}->{address});
print Dumper($obj->[0]->[0]->[0]->{object_status}->{availability_status});
print Dumper($obj->[0]->[0]->[1]->{member}->{address});
print Dumper($obj->[0]->[0]->[1]->{object_status}->{availability_status});
print Dumper($obj->[0]->[0]->[2]->{member}->{address});
print Dumper($obj->[0]->[0]->[2]->{object_status}->{availability_status});
print Dumper($obj->[0]->[0]->[3]->{member}->{address});
print Dumper($obj->[0]->[0]->[3]->{object_status}->{availability_status});

输出：

$VAR1 = '192.168.100.141';
$VAR1 = 'AVAILABILITY_STATUS_GREEN';
$VAR1 = '192.168.100.142';
$VAR1 = 'AVAILABILITY_STATUS_GREEN';
$VAR1 = '192.168.100.143';
$VAR1 = 'AVAILABILITY_STATUS_GREEN';
$VAR1 = '192.168.100.144';
$VAR1 = 'AVAILABILITY_STATUS_GREEN';

希望这会有所帮助，现在您应该能够使用循环遍历此数据结构。
