我有一些hashref格式的数据。我从graph.facebook.com获取数据 如何循环访问?
$var = \{
'data' => [
{
'id' => '312351465029_10154168935475030',
'name' => 'Timeline Photos 1'
},
{
'name' => 'Bangchak\'s cover photo',
'id' => '312351465029_10154168087455030',
},
{
'id' => '312351465029_10154168081875030',
'name' => 'Timeline Photos 2',
}
],
'paging' => {
'previous' => 'https://graph.facebook.com/v2.6/312351465029/2',
'next' => 'https://graph.facebook.com/v2.6/312351465029/3'
}
};
这些代码无效。
foreach $m ($var->{data})
{
if ( $m->{name} =~ /Timeline/i )
{
print "id = $m->{id}\n";
}
}

您需要取消引用数组(perldoc perldsc):
import marshal
# code ...
string1 = marshal.dumps(sp1)
