批量新增，传的是数组[{id: null
user_name: "ssssss"
user_password: "ssssss"
_XID: "row_10"},{id: null
user_name: "ssssss2"
user_password: "ssssss"
_XID: "row_10"}],$data怎样写？如下无效if(request()->isPost()){
$data = [['user_name' => input('user_name'),'user_password' => input('user_password')]

];

if(Db::name('user') -> insertAll($data))
