1:配置支付宝签名

2.将支付php skd放到vendor目录,重命名为alipay,请求支付宝生成get形式链接(config配置文件地址alipay/config.php)

$response = $aop->pagePay($payRequestBuilder, $config['return_url'], $config['notify_url']);这步调用根据我的需求修改了部分代码,返回了get链接

    /*** 发起支付宝订单,返回支付链接*/public function order_pay(){$config = array(//应用ID,您的APPID。'app_id' => "appid",//商户私钥'merchant_private_key' => "私钥",//异步通知地址'notify_url' => $this->request->domain().url('notify/notify'),//同步跳转'return_url' => $this->request->domain().url('notify/return_url'),//编码格式'charset' => "UTF-8",//签名方式'sign_type' => "RSA2",//支付宝网关'gatewayUrl' => "https://openapi.alipay.com/gateway.do",//支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。'alipay_public_key' => "支付宝公钥",);
//                    include_once VENDOR_PATH . '/alipay/config.php';include_once VENDOR_PATH . '/alipay/pagepay/service/AlipayTradeService.php';include_once VENDOR_PATH . '/alipay/pagepay/buildermodel/AlipayTradePagePayContentBuilder.php';//商户订单号，商户网站订单系统中唯一订单号，必填$out_trade_no = $model->get_order_id();//订单名称，必填$subject = $info['name'];//付款金额，必填if(!empty($info['month'])){$total_amount = $info['price'] * $data['params']['number'] * $data['params']['duration'];}else{$total_amount = $info['price'] * $data['params']['number'];}//商品描述，可空
//                    $body = '商品描述';//构造参数$payRequestBuilder = new \AlipayTradePagePayContentBuilder();
//                    $payRequestBuilder->setBody($body);$payRequestBuilder->setSubject($subject);$payRequestBuilder->setTotalAmount($total_amount);$payRequestBuilder->setOutTradeNo($out_trade_no);$payRequestBuilder->setTimeExpress('6h');$aop = new \AlipayTradeService($config);/*** pagePay 电脑网站支付请求*///此处我的需求是返回链接,没有用表单形式,所以修改了部分代码$response = $aop->pagePay($payRequestBuilder, $config['return_url'], $config['notify_url']);$model->where(['id'=>$id])->update(['pay_url'=>$response]);//输出链接return json(['code'=>0,'msg'=>$response]);}

3.支付回调

/*** 支付异步回调*/public function notify(){$post = $this->request->param();include_once VENDOR_PATH . '/alipay/pagepay/service/AlipayTradeService.php';$config = array(//应用ID,您的APPID。'app_id' => "appid",//商户私钥'merchant_private_key' => "",//异步通知地址'notify_url' => $this->request->domain().url('notify/notify'),//同步跳转'return_url' => $this->request->domain().url('notify/return_url'),//编码格式'charset' => "UTF-8",//签名方式'sign_type' => "RSA2",//支付宝网关'gatewayUrl' => "https://openapi.alipay.com/gateway.do",//支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。'alipay_public_key' => "",);$alipaySevice = new AlipayTradeService($config);$alipaySevice->writeLog(var_export($_POST,true));$result = $alipaySevice->check($post);if($result){$model = new UserOrderModel();if($_POST['trade_status'] == 'TRADE_FINISHED') {//判断该笔订单是否在商户网站中已经做过处理//如果没有做过处理，根据订单号（out_trade_no）在商户网站的订单系统中查到该笔订单的详细，并执行商户的业务程序//请务必判断请求时的total_amount与通知时获取的total_fee为一致的//如果有做过处理，不执行商户的业务程序//注意：//退款日期超过可退款期限后（如三个月可退款），支付宝系统发送该交易状态通知}else if ($_POST['trade_status'] == 'TRADE_SUCCESS') {//判断该笔订单是否在商户网站中已经做过处理//如果没有做过处理，根据订单号（out_trade_no）在商户网站的订单系统中查到该笔订单的详细，并执行商户的业务程序//请务必判断请求时的total_amount与通知时获取的total_fee为一致的//如果有做过处理，不执行商户的业务程序//注意：//付款完成后，支付宝系统发送该交易状态通知}echo 'success';}else{echo 'fail';}}
