微信支付问题

$attributes= [
 "body" => "充值1.00元" ,
 "detail" => "充值1.00元",
"total_fee" => 100,
"out_trade_no" => "trading_831",
"notify_url" => "http://100huatong.local/api/weixin/notify" 
];
$order = new Order($attributes); 
$weChat = app('wechat'); 
$payment = $weChat->payment; 
return $payment->pay($order);

不知道这样对不对。

输出结果

{"return_code":"FAIL","return_msg":"缺少参数"}<br></br>
