tp5 操作monodb 无model的CURD写法（demo版）

thinkphp 5.0 增加mongodb 使用，配置方式如下，在config.php文件中追加

// mongo 数据库配置
'db_mongo' => [
    'type'    =>   '\think\mongo\Connection',
    'hostname'    =>   '127.0.0.1',
    'database'    =>   'test',
    'username'    =>   '',
    'password'     =>   '',
    'hostport'    =>   27017,

],

 如图所示
