Perl数组和哈希引用处理

Question

我的问题是我在脚本结束时没有输出..解析时的所有打印都没问题，但结尾处的数组是空的。

我做错了什么？ 这不是处理裁判的方法吗？

my %branches = ();

    $content = $content->decoded_content;

没有任何输入数据很难弄明白，因为这意味着我们无法在自己的机器上运行脚本的副本！ 如果您的示例代码是自包含的，通常非常有用！

也就是说，我认为你的问题源于做这样的事情：

my $branch_ref = $branches{$1};
%tmp_branch = %$branch_ref;

第二行执行散列的浅表副本 ，因此%tmp_branch不再是与$branches{$1}引用的散列相同的散列。 将数据添加到%tmp_branch哈希时，不会将数据添加到$branches{$1}哈希。

@tmp_array同样受苦。
