woocommerce对接第四方支付通道okpay 前言用wordpress+woocommerce做跨境独立站的朋友为了顺利收款，会对接各种国外的本地收款渠道。主流的用paypal等，不过通道越大。合规查的越严，小众的一些三方或四方通道，限制也会小一点。本文分享菲律宾四方通道okpay的对接过程。{card-default label="收银台" width="75%"}{/card-default}对接流程一般都是申请通道账号，根据接口文档开发插件，然后测试调试，通过后上线。支付插件主要有三个函数和签名函数。三个函数为提交订单信息获取支付链接，异步通知处理，同步跳转处理函数。核心代码md5签名函数 public function get_sign($srcArray, $merKey){ if(null == $srcArray){ return "123456"; } //先干掉sign字段 $keys = array_keys($srcArray); $index = array_search("sign", $keys); if ($index !== FALSE) { array_splice($srcArray, $index, 1); } //对数组排序 ksort($srcArray); //生成待签名字符串 $srcData = ""; foreach ($srcArray as $key => $val) { if($val === null || $val === "" ){ //值为空的跳过，不参与加密 continue; } $srcData .= "$key=$val" . "&"; } $srcData = substr($srcData, 0, strlen($srcData) - 1); //生成签名字符串 $sign = md5($srcData.$merKey); return $sign; }post提交函数 public function http_post($url, $sendInfo) { try { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60); curl_setopt($ch, CURLOPT_TIMEOUT, 60); // Set headers for JSON content curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Accept: application/json' )); // Encode $sendInfo as JSON $json_data = json_encode($sendInfo); curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data); $curl_result = curl_exec($ch); curl_close($ch); return $curl_result; } catch (Exception $e) { return null; } }支付成功后异步回调处理函数 if (($_SERVER['REQUEST_METHOD'] === 'POST') && preg_match("/wc_okpay_notify/i", $_SERVER['REQUEST_URI'])) { $response = file_get_contents("php://input"); error_log(__METHOD__ . PHP_EOL .print_r($response, true)); //参数 $respj = json_decode($response, true, 512, JSON_BIGINT_AS_STRING); //error_log(__METHOD__ . PHP_EOL .print_r($respj['data'], true)); if ($respj['data']) { //组织签名串 //$res_sign = $this->get_sign($_POST, $this->okpay_merchant_key); #订单号 $mref = $respj['data']['orderNo']; $sref = $respj['data']['businessNo'];; #写入数据库 $query = "update {$wpdb->prefix}okpay_data set order_state = 'C' where mref = '".addslashes($mref)."'"; $wpdb->query($query); #后续处理 $check_query = $wpdb->get_results("SELECT order_id FROM {$wpdb->prefix}okpay_data WHERE mref = '".addslashes($mref)."'", ARRAY_A); $check_query_count = count($check_query); if($check_query_count >= 1){ $order_id= $check_query[0]['order_id']; $order = new WC_Order($order_id); $statustr = $this->okpay_processing; $order->update_status($statustr, __('Order has been paid by ID: ' . $sref, 'okpay-for-woocommerce')); wc_reduce_stock_levels( $order->get_id() ); add_post_meta( $order_id, '_paid_date', current_time('mysql'), true ); update_post_meta( $order_id, '_transaction_id', wc_clean($order_id) ); $order->payment_complete(wc_clean($order_id)); $woocommerce->cart->empty_cart(); } }项目完整代码【支付插件】woocommerce对接第三方支付接口okpay
