perl操纵mongodb
如上图所示，向数据库里插入了数据，为什么返回的是一个HASH值。
我的代码如下：use strict ;
use warnings;
use MongoDB;
use MongoDB::OID;
useMongoDB::Connection;
use MongoDB::Database;
useMongoDB::Collection;
#use Test::More tests =>1;
my $conn = MongoDB::Connection->new;
my $db = $conn->test;
my $users = $db->users;
my $id = $users->insert({"name" => "tangke"});
my $all_users = $users->find({"name"=>"tangke"});
print $all_users; 解决了。
