paypal php退款接口文档,PayPal的Restful
記錄之用。
1.移動App中想要接入PayPal支付，婉轉的采用PayPal的一種最簡便的方式(網頁版)。
PayPal支付
- 商品名稱：流量支付
- 訂單編號：{$out_trade_no}
- 金額：${$order_total}
border="0" name="submit" alt=" PayPal - The safer, easier way to pay online">
這方式就是支付的時候體驗不太好，容易500的錯誤，網絡的限制。
2.支付完成后那就是回調了(這里使用的PayPal的IPN回調機制)：
/** * PayPal回調通知 */ public function paypal() { $ipn = file_get_contents('php://input');// $ipn = "mc_gross=399.00&protection_eligibility=Eligible&address_status=confirmed&payer_id=XEMQ4LGLL3E8U&address_street=%BF%C6%D4%B0%C2%B72%BA%C5A8%D2%F4%C0%D6%B4%F3%CF%C3&payment_date=19%3A18%3A52+Apr+07%2C+2017+PDT&payment_status=Completed&charset=gb2312&address_zip=518000&first_name=li&mc_fee=15.86&address_country_code=CN&address_name=%C9%EE%DB%DA%CA%D0%A1%A1%CA%A5%C2%EB%BF%C6%BC%BC¬ify_version=3.8&custom=664&payer_status=verified&business=yu.yu-facilitator%40zmartec&address_country=China&address_city=%C9%EE%DB%DA%CA%D0&quantity=1&verify_sign=AomRS5l2W2xlt2An.GaSrAzpCl-NAi.rf7W.QGkzsUIdF5RMnpDPvDzw&payer_email=zmartec%40zmartec&txn_id=32U88448K71697337&payment_type=instant&last_name=tao&address_state=GUANGDONG&receiver_email=yu.yu-facilitator%40zmartec&payment_fee=15.86&receiver_id=PEAD5Y5KWXRJU&txn_type=web_accept&item_name=SIGMA%2BSD1000&mc_currency=USD&item_number=&residence_country=US&test_ipn=1&transaction_subject=&payment_gross=399.00&ipn_track_id=b2b22318a3e9"; vendor('PaypalIPN.PaypalIPN') or die("方案7引入失敗"); $pipn = new \PaypalIPN(); $ipn_response = $pipn->verifyIPN($ipn); // 驗證通過&轉換數據類型為array if (true === $ipn_response) { $raw_post_array = explode('&', $ipn); $myPost = array(); foreach ($raw_post_array as $keyval) { $keyval = explode('=', $keyval); if (count($keyval) == 2) { // 轉換urlencode的+為%2B if ($keyval[0] === 'payment_date') { if (substr_count($keyval[1], '+') === 1) { $keyval[1] = str_replace('+', '%2B', $keyval[1]); } } $myPost[$keyval[0]] = urldecode($keyval[1]); } } $fields = "od.`uid`,od.`currency`,od.`product_id`"; $order_detail = $this->_model->orderDetail($myPost['custom'], $fields); // 卡號iccid $iccid = $this->_model->getIccidByid($order_detail[0]['uid']);print_r($iccid); $iccid = $iccid[0]['iccid']; // 套餐包id $product_id = $this->_model->getProductIdById($order_detail[0]['product_id']); $product_id = $product_id[0]['product_id']; // ①檢查payment_status狀態 if ("Completed" == $myPost['payment_status']) { // ②確保txn_id不重復 if ($this->_model->checkPayPalTxn($myPost['txn_id'])) { // ③確保郵件未被更改 if ($this->paypayl_receiver_email == $myPost['receiver_email']) { // ④確保價格、商品與訂單符合 if ($order_detail[0]['order_total'] == $myPost['mc_gross'] && $order_detail[0]['currency'] == $myPost['mc_currency']) { $data = array( 'status'=>'completed', 'payment_methods' => 'PayPal', 'trade_no'=>$myPost['txn_id'], 'changed_time'=>time() ); $pay_result = $this->_model->saveOrderData( $data , $myPost['custom'] ); $this->hong_cha_package_order($order_detail[0]['out_trade_no'], $myPost['custom'], $product_id, $iccid, $order_detail[0]['product_amount']); } else { echo "貨幣、價格與訂單不符，請聯系管理員."; } } else { echo "訂單信息被修改，請聯系管理員."; } } else { echo "訂單已被處理，請勿重復."; } } else { echo "訂單未支付完成."; } } else { echo "數據被黑，無法驗證通過."; } }
3.支付、回調之后就不可避免的要退款了：
/** * PayPal退款 */ public function paypal_refund() { $txn_id = I('txn_id'); $id = I('id'); if ($this->is_data_valid(array($txn_id))) { $url = "/$txn_id/refund"; $post_data = "{}"; $access_token = $this->ger_access_token(); $header = array( "Content-Type: application/json", "Authorization: Bearer $access_token" ); $output = http_post_paypal($url, $post_data, $header); if (false === $output || false === $access_token) { $this->_data['data'] = ''; $this->_data['error'] = true; $this->_data['message'] = '網絡異常，請您稍后重試'; } $output = json_decode($output, TRUE); if ($txn_id == $output['sale_id'] && "completed" == $output['completed']) { $this->_model->saveOrderData( array('status'=>'refund_success', 'changed_time'=>time()), $id ); $this->_data['data'] = ''; $this->_data['error'] = false; $this->_data['message'] = '退款已提交'; } elseif ("TRANSACTION_REFUSED" == $output['name']) { $this->_data['data'] = ''; $this->_data['error'] = false; $this->_data['message'] = '退款已提交，請勿重復'; } } $this->response($this->_data, 'json'); }
function.php文件：
/** * curl POST請求 用作PayPal回調 * @param string $url * @param string $post_data * @return array */ function http_post_paypal($url, $post_data, $header=array(), $client_id='', $secret='') { $ch = curl_init($url); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); if ($client_id && $secret) { curl_setopt($ch, CURLOPT_USERPWD, "[$client_id]:[$secret]"); // 傳遞一個連接中需要的用戶名和密碼，格式為："[username]:[password]"。 } curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 獲取數據返回 curl_setopt($ch, CURLOPT_HTTPHEADER, $header) ; // 在啟用 CURLOPT_RETURNTRANSFER 時候將獲取數據返回array('Expect:') $output = curl_exec($ch); if ( curl_errno($ch) ){ return false; } return $output; }
ps：退款的時候需要獲取token，有碰到問題的可以參考另一篇文章
