2019獨(dú)角獸企業(yè)重金招聘Python工程師標(biāo)準(zhǔn)>>>

今天一個項(xiàng)目用微信掃碼支付，客戶掃碼后卡死在前臺。但是金額已經(jīng)支付成功了。通過百度發(fā)現(xiàn)https://pay.weixin.qq.com/wiki/doc/api/micropay.php?chapter=9_10&index=1。屬于下面情況：

提醒1：提交支付請求后微信會同步返回支付結(jié)果（后續(xù)說明異步的方法）。當(dāng)返回結(jié)果為“系統(tǒng)錯誤”時，商戶系統(tǒng)等待5秒后調(diào)用【查詢訂單API】，查詢支付實(shí)際交易結(jié)果；當(dāng)返回結(jié)果為“USERPAYING”時，商戶系統(tǒng)可設(shè)置間隔時間(建議10秒)重新查詢支付結(jié)果，直到支付成功或超時(建議30秒)；

我用計(jì)劃任務(wù)做了查詢訂單API，根據(jù)訂單支付成功結(jié)果修改ecstore表的狀態(tài)。代碼如下：

<?php /*** 微信檢查訂單后，修改ecsotre表支付狀態(tài)*/Class checkPay{public function __construct() {date_default_timezone_set('Asia/Shanghai');require_once("../config/config.php");require_once("./dbase.php");$this->dbase = new DB();$this->dbase->connect(DB_HOST, DB_USER, DB_PASSWORD,DB_NAME );$this->is_log = "./logs/checkPay".date("Ymd").".log";$this->wx['Appid'] = "*";$this->wx['mch_id'] = "*";$this->wx['key'] = "*"; }public function getSdbOrder() {$sql = "select order_id From sdb_b2c_orders where pay_status='0' and status='active'"; //pay_status表示未成功的$rows= $this->dbase->get_rows($sql);foreach ($rows as $key => $value) {$cash_fee = $this->getWxOrderInfo($value['order_id']);if ($cash_fee>0) {$sql = "UPDATE `sdb_b2c_orders` SET `pay_status`='1', `payed`='{$cash_fee}',updatestats_tag='微信查帳修改' WHERE `order_id`={$value['order_id']}";$this->dbase->query($sql); $this->dbase->write_log("line 32: sql=".$sql,$this->is_log);}}}public function getWxOrderInfo($order_id) {//微信的$wx['Appid'] = $this->wx['Appid'];$wx['mch_id'] = $this->wx['mch_id'];//$wx['out_trade_no'] = "161222225332249";$wx['out_trade_no'] = $order_id;$wx['nonce_str'] = "abcdefg2abcdefg";$wx['sign'] = $this->weiXinSign($wx);$xmlStr = "<xml>";$xmlStr .="<appid>{$wx['Appid']}</appid>";$xmlStr .="<mch_id>{$wx['mch_id']}</mch_id>";$xmlStr .="<nonce_str>{$wx['nonce_str']}</nonce_str>";$xmlStr .="<out_trade_no>{$wx['out_trade_no']}</out_trade_no>";$xmlStr .="<sign>{$wx['sign']}</sign>";$xmlStr .="</xml>";$sendpost = $this->sendpost($xmlStr);$this->dbase->write_log("line 35: sendpost=".$sendpost,$this->is_log);$postObj = simplexml_load_string($sendpost, 'SimpleXMLElement', LIBXML_NOCDATA);$cash_fee= 0 ;if ($postObj->trade_state =='SUCCESS' && $postObj->result_code=='SUCCESS' ) {$cash_fee= sprintf("%.2f",$postObj->cash_fee/100);}return $cash_fee;}private function weiXinSign($wx) {//微信的$signArr = array();$signArr['appid']= $this->wx['Appid'];$signArr['mch_id']= $this->wx['mch_id'];$signArr['nonce_str']=$wx['nonce_str'];$signArr['out_trade_no']=$wx['out_trade_no'];ksort($signArr);$signArr2 = array();foreach ($signArr as $key => $value) {$signArr2[] = $key.'='.$value;}//去掉開頭的&并且進(jìn)行MD5加密處理$stringSignTemp = implode("&",$signArr2).'&key='.$this->wx['key'];$sign = md5($stringSignTemp);$sign = strtoupper($sign);return $sign;}private function sendpost($data){$url = "https://api.mch.weixin.qq.com/pay/orderquery";$ch = curl_init(); $header[] = "Content-type: text/xml";//定義content-type為xml curl_setopt($ch, CURLOPT_URL, $url); //定義表單提交地址 curl_setopt($ch, CURLOPT_POST, 1); //定義提交類型 1：POST ；0：GET curl_setopt($ch, CURLOPT_HEADER, 0); //定義是否顯示狀態(tài)頭 1：顯示 ； 0：不顯示 curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//定義請求類型 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//定義是否直接輸出返回流 curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //定義提交的數(shù)據(jù)，這里是XML文件 $result = curl_exec($ch); curl_close($ch);//關(guān)閉 return $result;} }$cPay = new checkPay();$cPay->getSdbOrder();使用計(jì)劃任務(wù)php checkPay.php 就可以了上面還有一個工作沒有做，就是商派的ecstore沒有支付訂單記錄。這個后續(xù)有要求在加入。分析一下，其實(shí)就是涉及下面的幾個表INSERT INTO `zhihuimendian`.`sdb_ectools_order_bills` (`rel_id`, `bill_id`, `money`) VALUES ('161222200529117', '16122220052911700001', '33.900'); //插入支付表與order的關(guān)聯(lián)UPDATE `sdb_b2c_orders` SET `pay_status`='1'， `payed`='0.100'，updatestats_tag='微信查帳修改' WHERE `order_id`=161222200529117; //修改支付狀態(tài)
