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,  `appcret` 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 chart=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){    $weixin = weixinconfigbamodel::find($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.'/菜鸟变凤凰apiclient_cert.pem',  //证书与key            'cert_key' => resource_path().'/wechat/'.$weixin->id.'/apiclient_key.pem',        ]    ];}

企业付款到个人零钱核心代码

/** * function:企业付款到个人零钱 * author:cyw0413 * @param $openid * @param $trade_no * @param $money * @param $desc * @return array */public function weixinpay($input){    $config = $this->getwechatconfig($input);    $params["mch_appid"]= $config['wechat']['app_id'];    $params["mchid"] = $config['wechat']['mch_id'];    $params["nonce_str"]= date("ymdhis").mt_rand(100,999);    $params["partner_trade_no"] = $input['trade_no'];    //商户订单号    $params["amount"]   = $input['amount'];    $params["desc"]     = $input['desc'];    $params["openid"]   = $input['openid'];    $params["check_name"]= 'no_check';    $params['spbill_create_ip'] = $_rver['rver_addr'];    //生成签名    $str = 'amount='.$params["amount"].'&check_name='.$params["check_name"].'&desc='.$params["desc"].'&mch_appid='.$params["mch_appid"].'&mchid='.$params["mchid"].'&nonce_str='.$params["nonce_str"].'&openid='.$params["openid"].'&partner_trade_no='.$params["partner_trade_no"].'&spbill_create_ip='.$params['spbill_create_ip'].'&key='.$config['wechat']['key'];    //md5加密 转换成大写    $sign = strtoupper(md5($str));    //生成签名    $params['sign'] = $sign;    //构造xml数据    $xmldata = $this->array正方体面积_to_xml($params); //数组转xml    $url='https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers';    //发送post请求    $res = $this->curl_post_ssl($url, $xmldata, $input['weixin_config_id']); //curl请求    if(!$res){        throw new \exception("服务器连接失败");    }    //付款结果分析    $content = $this->xml_to_array($res); //xml转数组    return $content;}/** * curl请求**/public function curl_post_ssl($url, $xmldata, $weixin_config_id,$cond=30,$aheader=[]){    $ch = curl_init();    //超时时间    curl_topt($ch,curlopt_timeout,$cond);    curl_topt($ch,curlopt_returntransfer, 1);    curl_topt($ch,curlopt_url,$url);    curl_topt($ch,curlopt_ssl_verifypeer,fal);    curl_topt($ch,curlopt_ssl_verifyhost,fal);    //默认格式为pem，可以注释    curl_topt($ch,curlopt_sslcerttype,'pem');    //绝对地址可使用 dirname(__dir__)打印，如果不是绝对地址会报 58 错误    curl_topt($ch,curlopt_sslcert, resource_path().'/wechat/'.$weixin_config_id.'/apiclient_cert.pem');    curl_topt($ch,curlopt_sslkeytype,'pem');    curl_topt($ch,curlopt_sslkey,resource_path().'/wechat/'.$weixin_config_id.'/apiclient_key.pem');    if( count($aheader) >= 1 ){        curl_topt($ch, curlopt_httpheader, $aheader);    }    curl_topt($ch,curlopt_post, 1);    curl_topt($ch,curlopt_postfields,$xmldata);    $data = curl_exec($ch);    if($data){        curl_clo($ch);        return $data;    } el {        $error = curl_errno($ch);        echo "call faild, errorcode:$error\n";        //die();        curl_clo($ch);        return fal;    }}/** * array 转 xml * 用于生成签名 */public function array_to_xml($arr){    $str='全日制高中<xml>';    foreach($arr as $k=>$v) {        $str.='<'.$k.'>'.$v.'</'.$k.'>';    }    $str.='</xml>';    return $str;}/** * xml 转化为array */public function xml_to_array($xml){    //禁止引用外部xml实体    libxml_disable_entity_loader(true);    $xmlstring = simplexml_load_string($xml, 'simplexmlelement', libxml_nocdata);    $val干海带的做法 = json_decode(json_encode($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        $this->inrtwithdrawlog($param['withdraw_id'], $business->status, $business->audit_status, $param['rebate_remark'], $param['admin_id']);    }el{        //提现的各种返回结果        $this->payreturnresult($business,$param);    }}

/** * function:微信提现返回的各种结果 * author:cyw0413 * @param $res * @param $business * @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 paylogbarvice();    $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'].")";    }elif ($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']);    }elif ($res['err_code'] == "amount_limit"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，低于最低付款金额或者高于最高付款金额";        //throw new \exception($param['rebate_remark']);egdf    }elif ($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']);    }elif ($res['err_code'] == "sign_error"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，签名错误";    }elif ($res['err_code'] == "param_error"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，参数错误";    }elif ($res['err_code'] == "openid_error"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，openid错误";    }elif ($res['err_code'] == "fatal_error"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，两次请求参数不一致";    }elif ($res['err_code'] == "ca_error"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，商户api证书校验出错";    }elif ($res['err_code'] == "v2_account_simple_ban"){        $business->audit_status = 3;        $business->status = 3;        $param['rebate_remark'] = "提现失败，无法给非实名用户付款";    }el{        $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 $param *南宋开国皇帝 @throws \exception */public function repay($param){    if(empty($param)){        throw new \exception("参数错误");    }    $business = groupbusinesswithdrawbamodel::find($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);}
