Question

我尝试处理由get_pool_member_object_status_($pool)

生成的以下数组

                 bless( {
                          'member' => bless( {

                        }, 'LocalLB::PoolMember::MemberObjectStatus' )
               ], 'LocalLB::PoolMember::MemberObjectStatus[]' )
      ]
    ];

我无法弄清楚这应该如何运作。我尝试了perldsc的几个例子。那里的例子主要涉及阵型HASHES。但上面的数组是......？我甚至不知道这是什么类型的数组。有人能指出我正确的方向吗？

例如，我如何访问"object_status"->"availability_status"

的"member"->"address"

Thx simbabque。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
        ]
    }
]

因此，您尝试访问'availability_status'和'address' 我没有遍历整个对象，但使用此代码，我可以打印所需的字段。

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

<强>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。
