PHP实现财务审核通过后返现金额到客户

应用场景：

有这么一个返现的系统，当前端客户发起提现的时候，后端就要通过审核这笔返现订单，才可以返现到客户的账号里。

**来看看下面的截图**

这里的业务场景就是经过两轮审核：销售审核，财务审核都通过后，后端就会付款一笔钱到客户，当然，这里财务审核会有很多种情况，不通过与通过，通过后直接付款又有很多种情况，详细可以查看微信付款到零钱的文档。下面就来看看具体你的代码实现

**微信支付配置**

**1，数据表大概如下**

CREATE TABLE `zmq_weixin_config` (
      `id` int(1) unsigned NOT NULL AUTO_INCREMENT COMMENT '微信公众平台编号，自增id',
      `weixin_name` varchar(10) NOT NULL COMMENT '微信公众平台名称',
      `token` varchar(100) NOT NULL,
      `appid` char(18) NOT NULL,
      `appsecret` char(32) NOT NULL,
      `access_token` varchar(300) NOT NULL,
      `api_ticket` varchar(300) DEFAULT NULL COMMENT '微信卡包api_ticket',
      `api_ticket_expired_at` datetime DEFAULT NULL COMMENT '微信卡包api_ticket过期时间',
      `mchid` varchar(20) DEFAULT NULL COMMENT '商户号',
      `mchkey` varchar(50) DEFAULT NULL COMMENT '支付密钥',
      `expired_at` timestamp NULL DEFAULT NULL COMMENT 'access_token过期时间，会自动更新',
      `updated_at` timestamp NULL DEFAULT NULL COMMENT '记录更新时间',
      `created_at` timestamp NULL DEFAULT NULL COMMENT '创建时间',
      `sort_order` smallint(5) NOT NULL DEFAULT '0' COMMENT '排序',
      `points_url` varchar(100) DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=MyISAM AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC COMMENT='微信配置表';

**2 .config的配置方法**

/**
     * 获取微信支付配置
     * 这里我是把配置信息存储在数据表里，方便调用
     * $param是从controller里传值过来：weixin_config_id，notify_url
     * @return array
     */
    public function getWechatConfig($param)
    {
        $weixin = WeixinConfigBaseModel::find($param['weixin_config_id']);
        if (empty($weixin)) {
            throw new Exception('微信配置ID错误');
        }
    
        return [
            'wechat' =>[
                $app_id => $weixin->appid,
                'mch_id' => $weixin->mchid,
                'notify_url' => empty($param['notify_url']) ? '' : $param['notify_url'],  //回调url
                'key' => $weixin->mchkey,
                'cert_client' => resource_path().'/wechat/'.$weixin->id.'/apiclient_cert.pem',  //证书与key
                'cert_key' => resource_path().'/wechat/'.$weixin->id.'/apiclient_key.pem',
            ]
        ];
    }

    /**

    public function curl_post_ssl($url, $xmldata, $weixin_config_id,$second=30,$aHeader=[]){
        $ch = curl_init();
        //超时时间

        }

    }
    
    /**

    public function xml_to_array($xml){
        //禁止引用外部xml实体

        $val = json_decode(json_encode($xmlString),true);
        return $val;
    }

财务审核，也就是微信返现到零钱，这个时候会返回成功结果，或者是各种不成功的结果

**这里我用一个方法封装**

//财务审核
    if($param['status'] == 2){
    
        //判断返现金额与修改后的金额
        if($before_rebate_amount != $param['rebate_amount']){
            //返现金额不相等，则出款金额改变
            $out_amount = $param['rebate_amount'] - $before_rebate_amount ;
            $this->outMount($business->business_id,$out_amount);
        }
    
        if($param['rebate_status'] == 9){
            //财务拒绝通过
            $business->audit_status = $param['rebate_status'];
            $business->rebate_amount = $param['rebate_amount'];
            $business->status = 6;
            $business->save();
    
            //生成日志
            $this->insertWithdrawLog($param['withdraw_id'], $business->status, $business->audit_status, $param['rebate_remark'], $param['admin_id']);
    
        }else{
            //提现的各种返回结果
            $this->payReturnResult($business,$param);
        }
    }

/**

     * @param $param
     */
    public function payReturnResult($business,$param)
    {
        $input = [
            'weixin_config_id' => 20 ,
            'openid'           => $business->business->open_id,
            'amount'           => $param['rebate_amount'] * 100,
            'trade_no'         => $business->order_sn, //商户订单号
            'desc'             => "微信提现"
        ];
    
        $pay = new PayLogBaseService();
        $res = $pay->weixinPay($input);
    
        if($res['result_code']=="SUCCESS"){
            //提现成功
            $business->audit_status = 4;
            $business->status = 4;
            $business->rebate_amount = $param['rebate_amount'];
            $param['rebate_remark'] = "已付款(".$param['rebate_amount'].")";
    
        }elseif ($res['err_code'] == "MONEY_LIMIT"){
            $business->audit_status = 3;
            $business->status = 3;
            $param['rebate_remark'] = "提现失败，已达到付款给此用户额度上限";

            //throw new \Exception($param['rebate_remark']);
    egdf
        }elseif ($res['err_code'] == "NOTENOUGH"){
            $business->audit_status = 3;
            $business->status = 3;
            $param['rebate_remark'] = "提现失败，付款帐号余额不足或资金未到账";
            //throw new \Exception($param['rebate_remark']);
    
        }elseif ($res['err_code'] == "SIGN_ERROR"){

        }elseif ($res['err_code'] == "PARAM_ERROR"){
            $business->audit_status = 3;
            $business->status = 3;
            $param['rebate_remark'] = "提现失败，参数错误";

        }elseif ($res['err_code'] == "FATAL_ERROR"){

        }elseif ($res['err_code'] == "CA_ERROR"){
            $business->audit_status = 3;
            $business->status = 3;
            $param['rebate_remark'] = "提现失败，商户API证书校验出错";
    
        }elseif ($res['err_code'] == "V2_ACCOUNT_SIMPLE_BAN"){
            $business->audit_status = 3;

        }else{
            $business->audit_status = 3;
            $business->status = 3;
            $param['rebate_remark'] = "提现失败，服务器繁忙，请稍后再试";
            //throw new \Exception($param['rebate_remark']);
        }
    
        $business->save();
    
    }

当微信平台余额不足或者出现各种错误而提现失败的时候，这里还有支持重新付款的功能：其实就是点击按钮后重新调用付款到零钱的功能，知道成功付款

/**
     * Function:重新付款
     * Author:cyw0413
     * @param $param
     * @throws \Exception
     */
    public function repay($param)
    {
        if(empty($param)){
            throw new \Exception("参数错误");
        }
    
        $business = GroupBusinessWithdrawBaseModel::find($param['withdraw_id']);
        if(empty($business)){
            throw new \Exception("不存在！");
        }
    
        if($business->audit_status != 3){
            throw new \Exception("状态有错误");
        }
    
        //提现的各种返回结果
        $this->payReturnResult($business,$param);
    
    }
