標籤 php 實現財務審覈經過金額客戶欄目 PHP 简体版

應用場景：前端

有這麼一個返現的系統，當前端客戶發起提現的時候，後端就要經過審覈這筆返現訂單，才能夠返現到客戶的帳號裏。json

來看看下面的截圖後端

這裏的業務場景就是通過兩輪審覈：銷售審覈，財務審覈都經過後，後端就會付款一筆錢到客戶，固然，這裏財務審覈會有不少種狀況，不經過與經過，經過後直接付款又有不少種狀況，詳細能夠查看微信付款到零錢的文檔。下面就來看看具體你的代碼實現api

微信支付配置數組

1，數據表大概以下服務器

CREATE TABLE `zmq_weixin_config` (
  `id` int(1) unsigned NOT NULL AUTO_INCREMENT COMMENT '微信公衆平臺編號，自增id',
  `weixin_name` varchar(10) NOT NULL COMMENT '微信公衆平臺名稱',
  `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過時時間',
  `mchid` varchar(20) DEFAULT NULL COMMENT '商戶號',
  `mchkey` varchar(50) DEFAULT NULL COMMENT '支付密鑰',
  `expired_at` timestamp NULL DEFAULT NULL COMMENT 'access_token過時時間，會自動更新',
  `updated_at` timestamp NULL DEFAULT NULL COMMENT '記錄更新時間',
  `created_at` timestamp NULL DEFAULT NULL COMMENT '建立時間',
  `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的配置方法微信

/**

 * 這裏我是把配置信息存儲在數據表裏，方便調用
 * $param是從controller裏傳值過來：weixin_config_id，notify_url
 * @return array
 */
public function getWechatConfig($param)
{
    $weixin = WeixinConfigBaseModel::find($param['weixin_config_id']);
    if (empty($weixin)) {
        throw new Exception('微信配置ID錯誤');
    }

    return [
        'wechat' =>[
            $app_id => $weixin->appid,
            'mch_id' => $weixin->mchid,
            'notify_url' => empty($param['notify_url']) ? '' : $param['notify_url'],  //回調url
            'key' => $weixin->mchkey,
            'cert_client' => resource_path().'/wechat/'.$weixin->id.'/apiclient_cert.pem',  //證書與key
            'cert_key' => resource_path().'/wechat/'.$weixin->id.'/apiclient_key.pem',
        ]
    ];
}

財務審覈，也就是微信返現到零錢，這個時候會返回成功結果，或者是各類不成功的結果微信公衆平臺

這裏我用一個方法封裝curl

//財務審覈
if($param['status'] == 2){

    //判斷返現金額與修改後的金額
    if($before_rebate_amount != $param['rebate_amount']){
        //返現金額不相等，則出款金額改變
        $out_amount = $param['rebate_amount'] - $before_rebate_amount ;
        $this->outMount($business->business_id,$out_amount);
    }

    if($param['rebate_status'] == 9){
        //財務拒絕經過
        $business->audit_status = $param['rebate_status'];
        $business->rebate_amount = $param['rebate_amount'];
        $business->status = 6;
        $business->save();

        //生成日誌
        $this->insertWithdrawLog($param['withdraw_id'], $business->status, $business->audit_status, $param['rebate_remark'], $param['admin_id']);

    }else{
        //提現的各類返回結果
        $this->payReturnResult($business,$param);
    }
}

/**
 * Function:微信提現返回的各類結果
 * 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, //商戶訂單號
        'desc'             => "微信提現"
    ];

    $pay = new PayLogBaseService();
    $res = $pay->weixinPay($input);

    if($res['result_code']=="SUCCESS"){
        //提現成功
        $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;
        $param['rebate_remark'] = "提現失敗，已達到付款給此用戶額度上限";
        //throw new \Exception($param['rebate_remark']);

    }elseif ($res['err_code'] == "AMOUNT_LIMIT"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，低於最低付款金額或者高於最高付款金額";
        //throw new \Exception($param['rebate_remark']);
egdf
    }elseif ($res['err_code'] == "NOTENOUGH"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，付款賬號餘額不足或資金未到帳";
        //throw new \Exception($param['rebate_remark']);

    }elseif ($res['err_code'] == "SIGN_ERROR"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，簽名錯誤";

    }elseif ($res['err_code'] == "PARAM_ERROR"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，參數錯誤";

    }elseif ($res['err_code'] == "OPENID_ERROR"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，Openid錯誤";

    }elseif ($res['err_code'] == "FATAL_ERROR"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，兩次請求參數不一致";

    }elseif ($res['err_code'] == "CA_ERROR"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，商戶API證書校驗出錯";

    }elseif ($res['err_code'] == "V2_ACCOUNT_SIMPLE_BAN"){
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，沒法給非實名用戶付款";

    }else{
        $business->audit_status = 3;
        $business->status = 3;
        $param['rebate_remark'] = "提現失敗，服務器繁忙，請稍後再試";
        //throw new \Exception($param['rebate_remark']);
    }

    $business->save();

}

當微信平臺餘額不足或者出現各類錯誤而提現失敗的時候，這裏還有支持從新付款的功能：其實就是點擊按鈕後從新調用付款到零錢的功能，知道成功付款

/**
 * Function:從新付款
 * Author:cyw0413
 * @param $param
 * @throws \Exception
 */
public function repay($param)
{
    if(empty($param)){
        throw new \Exception("參數錯誤");
    }

    $business = GroupBusinessWithdrawBaseModel::find($param['withdraw_id']);
    if(empty($business)){
        throw new \Exception("不存在！");
    }

    if($business->audit_status != 3){
        throw new \Exception("狀態有錯誤");
    }

    //提現的各類返回結果
    $this->payReturnResult($business,$param);

}
