支付方式一:
paypal支付页面

正在跳转Paypal支付，请稍等。。。

支付回调,并进行ipn验证 将回调字段添加上$data['cmd'] = '_notify-validate'; 返回进行验证

/** * 支付回调函数 * @author gyj <375023402@qq.com> * @createtime 2018-08-24T11:38:23+0800 * @return */ public function notify(){ if(!$this->request->isPost()) die(); //记录支付回调信息 if(!empty($_POST)){ $notify_str = "支付回调信息:\r\n"; foreach ($_POST as $key => $value) { $notify_str.=$key."=".$value."; \r\n"; } } log_result($notify_str,"paypal"); //ipn验证 $data = https://www.it610.com/article/$_POST; $data['cmd'] = '_notify-validate'; $url = config('paypal.gateway'); //支付异步验证地址 $res = https_request($url,$data); //记录支付ipn验证回调信息 log_result($res,'paypal'); if (!empty($res)) { if (strcmp($res, "VERIFIED") == 0) {if ($_POST['payment_status'] == 'Completed' || $_POST['payment_status'] == 'Pending') { //付款完成，这里修改订单状态 $order_res = $this->order_pay($_POST); if(!$order_res){ log_result('update order result fail','paypal'); } return 'success'; } } elseif (strcmp($res, "INVALID") == 0) { //未通过认证，有可能是编码错误或非法的 POST 信息 return 'fail'; } } else { //未通过认证，有可能是编码错误或非法的 POST 信息return 'fail'; } return 'fail'; }

附上log_result函数 和https_result函数

log_result函数:

/** * 记录自定义日志 * @author gyj<375023402@qq.com> * @createtime 2018-08-24 14:12:01 * @param $msg 错误信息 * @param $type 写入类型 wechat aliyun * @return [type] [description] */ if(!function_exists('log_result')){ function log_result($msg='',$type='normal') { $dir = dirname(LOG_PATH)."/log/".$type."/"; if(!is_dir($dir)){ mkdir($dir,0777); } $dir .= date('Ym')."/"; $file = $dir.date('d').".log"; if(!is_dir($dir)){ mkdir($dir,0777); } file_put_contents($file,date('Y-m-d H:i:s')."\r\n".$msg."\r\n---------------------------------------------------------------\r\n", FILE_APPEND); }}

https_result函数:

/** * 发送post请求 * @author ganyuanjiang<3164145970@qq.com> * @createtime 2017-07-26 14:06:04 * @param string $url 请求地址 * @param array $post_data post键值对数据 * @return string */ if (!function_exists('https_request')) {function https_request($url,$data=https://www.it610.com/article/null){ header("Content-type: text/html; charset=utf-8"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)'); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_AUTOREFERER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $tmpInfo = curl_exec($ch); if (curl_errno($ch)) { return curl_error($ch); }curl_close($ch); return $tmpInfo; } }
