实现APP支付QQ，微信，支付宝三方的后端服务------php实现QQAPP支付

### 接上两篇支付宝支付和微信支付，下面我这边讲的是QQ支付： ###

##### 下面简单介绍下QQApp支付后端的实现（这边是用php实现的）： #####

##### 一、 一些琐碎的申请和设置的方式就不说明了，这些微信上都有说，但相比于支付宝吗，微信和QQ的文档相比差之千里，太简单太low了，并且没有SDKDEMO,但小伙伴们不用担心，下面是我这边封装好的一个类，可供直接使用，都有标注说明 #####

##### 一、封装好的QQ调用类库：（这个不管是app支付还是其他支付都可共用） #####

            }
        }
    
    
    }

##### 二、封装好的微信调用类库的工具类： #####

<?php /** * @encoding UTF-8 * @author wyb * @datetime 2017/320 * @Description QQ钱包APP支付控制器，不对外访问 */ namespace Pay\Controller; use Think\Controller; /** * @name * Class QQAppPayController */ class QQAppPayController extends Controller { //这是appId,对应的产品有对应的APPid private $appidByTarget = [ 'app标识' => '1232133213', 'app标识' => '1232133213', 'app标识' => '1232133213', 'app标识' => '1232133213', 'app标识' => '1232133213', 'app标识' => '1232133213', ]; //这是appId,对应的产品有对应的APPkey private $appKeyByTarget = [ 'app标识' => 'sd24sdfsdfsdfdfs', 'app标识' => 'sd24sdfsdfsdfdfs', 'app标识' => 'sd24sdfsdfsdfdfs', 'app标识' => 'sd24sdfsdfsdfdfs', 'app标识' => 'sd24sdfsdfsdfdfs', 'app标识' => 'sd24sdfsdfsdfdfs', ]; public function _initialize(){ } /** * 传入订单数据，进行整理、签名后，返回前端APP支付调起SDK信息 * @param array $order 待支付的订单信息，数组中的必要信息如下： * $order['id'] : 订单ID * $order['price'] : 实付金额，单位：元 * $order['notifyUrl'] : 支付端异步通知地址，用于接受订单的支付结果 * $order['target'] : 支付请求的来源，根据不同的来源，需要使用不同的支付账号信息 * $order['description'] ： 订单介绍 * $order['time'] ： 订单提交时间 */ public function getCallSDKInfo($order){ //做简单的参数检查 if(!$order || !is_array($order) || !$order['id'] || !$order['price'] || !$order['notifyUrl'] || !$order['target']){ return false; } // $time=time(); $wxappid = $this->appidByTarget[$order['target']];//应用ID 字符串 Vendor('qqPay.qqpay'); $QQPay = new \qqAppPay($wxappid); $params = [ 'body' => $order['description'], //必填项 商品描述 'out_trade_no' => $order['id'], //商家订单ID 'total_fee' => ($order['price']*100), //必填项 订单金额 'time_start' => date('yyyyMMddHHmmss',$order['add_time']), //可支付有效时间，超过则无效，需要重新请求 'time_expire' => date('yyyyMMddHHmmss',($order['add_time']+1800)), //可支付有效时间，超过则无效，需要重新请求 'trade_type' => 'APP', //必填项 交易类型固定写 APP 'fee_type' => 'CNY', //货币的类型 'notify_url' => $order['notifyUrl'], ]; $result = $QQPay->unifiedOrder($params); $sign_array=[ 'appId' => $result['appid'],//注意 $sign_array['appid'] 里的参数名必须是appid 'bargainorId' => $result['mch_id'],//注意 $sign_array['partnerid'] 里的参数名必须是partnerid 'tokenId' => $result['prepay_id'],//注意 $sign_array['prepayid'] 里的参数名必须是prepayid 'nonce' => $result['nonce_str'],//注意 $sign_array['noncestr'] 里的参数名必须是noncestr 'pubAcc' => '' ]; $sign_array['sign'] = $QQPay->appMakeSign($sign_array, $this->appKeyByTarget[$order['target']]);//appMakeSign()函数生成sign $sign_array['timestamp'] = $order['add_time']; return $sign_array; } }

##### 三、接下来你就可以根据你的相关产品订单信息进行调用相应的类方法，下面我就简单的写一下： #####

<?php /** * 根据相应的场景而写的支付接口 * Created by PhpStorm. * User: wyb * Date: 2017/3/22 * Time: 13:51 */ class productPayController extents Controller{ public function paymentAction(){ IS_POST ||$this->returnError(); //判断是否是POST $parameters = I('post.'); //接收所以参数，相应的参数校验我这里就不写，如果有问题可以给我留言反馈 $QqPay = new WechatAppPayController();//实例QQ的APP控制器类 $order['notifyUrl'] = 'http://xxxxxxxxxxxxxxx;//微信的回调接口 $data = $QqPay->getCallSDKInfo($order);//调用QQ生成预订单并整理好返回验签参数，这里调用上面的类封装的方法 return $data //这里可以根据你们前端定义接受什么数据类型进行转化 } }
