支付宝支付
（由app端自行调起支付宝/微信）
1.下载PHP版SDK
<?phpdefine('IN_ECS', true);/*App支付 PHP服务端*//*引入支付宝PHP SDK*/header("Content-type:text/html;charset=utf-8;");require_once('../alipay-sdk-PHP/aop/request/AlipayTradeAppPayRequest.php');require_once('../alipay-sdk-PHP/aop/AopClient.php');$user_id = isset($_REQUEST['user_id']) ? trim($_REQUEST['user_id']) : 0;$money = isset($_REQUEST['amount']) ? trim($_REQUEST['amount']) : 0;if($user_id == 0 || $money ==0){$result = array('code' => 1,'data'=>'缺少参数' );die(json_encode($result));}$aop = new AopClient;$aop->gatewayUrl = "/gateway.do";$aop->appId = "appid";$aop->format = "json";$aop->charset = "utf-8";$aop->signType = "RSA2";$aop->rsaPrivateKey = '开发者私钥';$aop->alipayrsaPublicKey = '支付宝公钥';//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay$request = new AlipayTradeAppPayRequest();//SDK已经封装掉了公共参数，这里只需要传入业务参数$trade_no = chongzhi_sn();//入库信息require(dirname(__FILE__) . '../../includes/init.php');include_once(ROOT_PATH .'includes/lib_clips.php');$user_m = get_user_info($user_id);$dbcontent = array('user_id' => $user_id,'amount' => $money,'user_name' => $user_m['user_name'],'payment' => "支付宝",'cz_sn' => $trade_no,'add_time' => gmtime());//传参信息$bizcontent = array('body' =>(string)$trade_no,'subject' =>'充值','total_amount' => $money,'out_trade_no' => (string)$trade_no,'product_code' => 'QUICK_MSECURITY_PAY','timeout_express'=> '30m');$bizcontent = json_encode($bizcontent);$request->setNotifyUrl("支付回调地址");$request->setBizContent($bizcontent);//这里和普通的接口调用不同，使用的是sdkExecute$response = $aop->sdkExecute($request);//htmlspecialchars是为了输出到页面时防止被浏览器将关键参数html转义，实际打印到日志以及http传输不会有这个问题//echo htmlspecialchars($response);//就是orderString 可以直接给客户端请求，无需再做处理。if($response){if($GLOBALS['db']->autoExecute($ecs->table('user_chongzhi'), $dbcontent, 'INSERT')){$result = array('code'=>0,'data'=>$response);}else{$result = array('code'=>1,'data'=>'意外出错，请联系客服。');}die(json_encode($result));}function chongzhi_sn(){/* 选择一个随机的方案 */mt_srand((double) microtime() * 1000000);return date('Ymd') . str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT);}?>
回调
<?phpdefine('IN_ECS', true);require_once('../alipay-sdk-PHP/aop/request/AlipayTradeAppPayRequest.php');require_once('../alipay-sdk-PHP/aop/AopClient.php');$aop = new AopClient;$aop->alipayrsaPublicKey = '支付宝公钥';$flag = $aop->rsaCheckV1($_POST, NULL, "RSA2");$myfile = fopen("testfile.txt", "a");fwrite($myfile, "\r\n");fwrite($myfile, json_encode($_POST));if($_POST['trade_status'] == 'TRADE_SUCCESS' ){//业务处理echo 'success';}else{echo 'fail';}fclose($myfile);?>
所需的私钥公钥获取地址
1.私钥 （下载rsa签名验签工具）https://docs./291/105971/
2.支付宝公钥
通过上传私钥，由支付宝生成公钥https://docs./291/105972/
3.支付宝联调日志排查/acceptance/cloudparse.htm
