支付-支付宝APP支付

沙箱环境太坑爹，没跑起来，直接上线测了。

集成支付宝提供的SDK，参照开发文档，基本上没什么问题

1、生成支付请求参数，用于调起支付宝APP

    public function toPay($body,$title,$out_trade_no, $price){        $aop = new AopClient;        $aop->gatewayUrl = self::ALIPAY_URL;        $aop->appId = self::APP_ID;        $aop->rsaPrivateKey = self::PRIVATE_KEY ;        $aop->format = "json";        $aop->charset = "UTF-8";        $aop->signType = "RSA2";        $aop->alipayrsaPublicKey = self::ALIPAY_PUBLIC_KEY;        //实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay        $request = new AlipayTradeAppPayRequest();        $bizcontent = json_encode([            "body"       => $body,            "subject"   => $title,            "out_trade_no"  => $out_trade_no,            "timeout_express"   => self::EXPIRE,            "product_code"  => "QUICK_MSECURITY_PAY",            "total_amount"  => $price        ]);        $request->setNotifyUrl($this->notify_url);        $request->setBizContent($bizcontent);        //这里和普通的接口调用不同，使用的是sdkExecute        $response = $aop->sdkExecute($request);        return $response;    }

2、验签

public function checkSign($postParams){    $aop = new AopClient;    $aop->alipayrsaPublicKey = self::ALIPAY_PUBLIC_KEY;    $flag = $aop->rsaCheckV1($postParams, NULL, "RSA2");    return $flag;}

3、处理异步通知

public function endOrder($postParams){    if(!$this->checkSign($postParams)){//验签        return false;    }    //验证app_id是否为该商户本身    if(self::APP_ID != $postParams['app_id']){        return false;    }    //校验通知中的seller_id（或者seller_email) 是否为out_trade_no这笔单据的对应的操作方    if((isset($postParams['seller_id']) && self::SELLER_ID != $postParams['seller_id']) ||        ( isset($postParams['seller_email']) && self::SELLER_MAIL != $postParams['seller_email']) ){        return false;    }    //商户需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号    $orderInfo = “取订单信息”    if(empty($orderInfo)){        return false;    }    //判断total_amount是否确实为该订单的实际金额（即商户订单创建时的金额）    if ($postParams['total_amount'] != $orderInfo['price']){        return false;    }    if( 0==$orderInfo["pay_status"] && ($postParams['trade_status']=="TRADE_SUCCESS" || $postParams['trade_status']=="TRADE_FINISHED")){//处理订单    }    return true;}

4、处理客户端支付返回

public function clientPayEnd($resultStatus, $result){    $res = json_decode($result, true);    $sign = $res["sign"];    $sign_type = $res["sign_type"];    $data = $res["alipay_trade_app_pay_response"];    $orderNo = $data["out_trade_no"];    $total_amount = $data["total_amount"];    //验签   $aop = new AopClient;    $aop->alipayrsaPublicKey = self::ALIPAY_PUBLIC_KEY;    $flag = $aop->verify(json_encode($data), $sign, NULL, $sign_type);    if(!$flag){        return ["flag"=>false, "errMsg"=>"非法签名"];    }    $orderInfo = "订单信息";    //商户需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号    if (empty($orderInfo)){        return ["flag"=>false, "errMsg"=>"未知错误."];    }    //判断total_amount是否确实为该订单的实际金额（即商户订单创建时的金额）    if ($total_amount != $orderInfo["price"]){        return ["flag"=>false, "errMsg"=>"支付金额异常"];    }    //校验通知中的seller_id（或者seller_email) 是否为out_trade_no这笔单据对应的操作方    if((isset($data['seller_id']) && self::SELLER_ID != $data['seller_id']) ||        ( isset($data['seller_email']) && self::SELLER_MAIL != $data['seller_email']) ){        return ["flag"=>false, "errMsg"=>"未知错误.."];    }    //验证app_id是否为该商户本身    if ($data["app_id"] != self::APP_ID){        return ["flag"=>false, "errMsg"=>"未知错误..."];    }    //订单支付成功    if (1 == $orderInfo['pay_status'] && in_array($resultStatus, ["9000","8000","6004"])){        return ["flag"=>true, "msg"=>"支付成功"];    }elseif(in_array($resultStatus, ["9000","8000","6004"])){//支付结果未知,发起查询     $flag = $this->queryTradeStatus($orderNo);        if ($flag){            return ["flag"=>true, "msg"=>"支付成功"];        }    }    return ["flag"=>false, "errMsg"=>"支付失败"];}

5、查询支付状态

    public function queryTradeStatus($orderNo){        $aop = new AopClient ();        $aop->gatewayUrl = self::ALIPAY_URL;        $aop->appId = self::APP_ID;        $aop->rsaPrivateKey = self::PRIVATE_KEY;        $aop->alipayrsaPublicKey=self::ALIPAY_PUBLIC_KEY;        $aop->apiVersion = '1.0';        $aop->signType = 'RSA2';        $aop->postCharset='UTF-8';        $aop->format='json';        $request = new AlipayTradeQueryRequest ();        $request->setBizContent(json_encode([            "out_trade_no"  => $orderNo        ]));        $result = $aop->execute ( $request);        $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";        $resultCode = $result->$responseNode->code;        if(!empty($resultCode)&&$resultCode == 10000){            $trade_status = $result->$responseNode->trade_status;            if($trade_status == "TRADE_SUCCESS" || $trade_status == "TRADE_FINISHED"){                return true;            }        }        return false;    }

6、交易关闭

    public function closeTrade($orderNo){        $aop = new AopClient ();        $aop->gatewayUrl = self::ALIPAY_URL;        $aop->appId = self::APP_ID;        $aop->rsaPrivateKey = self::PRIVATE_KEY;        $aop->alipayrsaPublicKey=self::ALIPAY_PUBLIC_KEY;        $aop->apiVersion = '1.0';        $aop->signType = 'RSA2';        $aop->postCharset='utf-8';        $aop->format='json';        $request = new AlipayTradeCloseRequest ();        $request->setBizContent(json_encode([            "out_trade_no"  => $orderNo        ]));        $result = $aop->execute ( $request);        $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";        $resultCode = $result->$responseNode->code;        if(!empty($resultCode)&&$resultCode == 10000){            return true;        } else {            return false;        }    }
