你会认为这是一件简单的事情.我有一个在我的集合中的对象ID列表.我想基于对象ID获得单个记录.谷歌搜索,但没有任何帮助.

所以我有对象ID:5106c7703abc120a04070b34

my $client = MongoDB::MongoClient->new;
my $db = $client->get_database( 'myDatabase' );

my $id_find = $db->get_collection('mycollection')->find({},{_id =>      MongoDB::OID->new(value => "5106c7703abc120a04070b34")});

print Dumper $id_find;

这打印:

                 '_skip' => 0,
                 '_ns' => 'MindCrowd_test.Users',
