微信企业付款到零钱

这里是一个测试代码，仅供参考，运行没问题，但是用到线上的话建议修改一下逻辑，多做些风险处理。

public function sendMoney(){
        header("Content-Type: text/html;charset=utf-8");
        $amount = $this->request->request("money");
        $re_openid = $this->openid;
        $total_amount = (100) * $amount;
        $time = date('Y-m-d H:i:s',time());
        //校验金额
        $user = Db('user')->where(array('wx_id' => $re_openid))->find();
        if(!$user){
            $this->error(__('Please login first'), null, -1);
        }
        if($user['money'] < $amount){
            $this->error(__('余额不足'));
        }
        $data=array(
            'mch_appid'=>config('site.app_id')?config('site.app_id'):'',//商户账号appid

            'nonce_str'=>$this->createNoncestr(),//随机字符串
            'partner_trade_no'=> date('YmdHis').rand(1000, 9999),//商户订单号
