1.平臺下單接口
參考地址
注意:若是微信公眾號支付 請使用 qmf.webPay 并在 微信公眾號的環境中測試

$mdKey = 'fcAmtnx7MwismjWNhNKdHC44mNXtnEQeJkRrhKJwyrW2ysRR';$mid = '898340149000005';$tid = '88880001';$merOrderId = '3194' . 'SH20191120093138668264';$msgSrc = 'WWW.TEST.COM';$time = time();$notifyUrl = $_W['siteroot'] . './addons/xt_agent/payment/yinlian/notify.php';$requestTimestamp = date('Y-m-d H:i:s',$time);$msgType = 'qmf.webPay';//微信支付：WXPay.jsPay，支付寶支付：trade.jsPay，銀聯支付：qmf.jspay(qmf.webPay)//根據實際情況，回調時攜帶的參數$attachedData = ['money' => $money,'module' => $module,'number' => $number,'number2' => $number2,'uniacid' => $_W['uniacid'],'acid' => $_W['acid'],];$attachedData = json_encode($attachedData);///轉為json類型$data = ['instMid' => 'YUEDANDEFAULT',//業務類型'merOrderId' => $merOrderId,//訂單號'mid' => $mid,//商戶號'msgSrc' => $msgSrc,//消息來源'msgType' => $msgType,//消息類型'orderDesc' => '測試',//訂單描述'requestTimestamp' => $requestTimestamp,//報文請求時間'tid' => $tid,//終端號'totalAmount' => '1',//支付金額'notifyUrl' => $notifyUrl,//支付結果通知地址，結果頁面會將返回參數通過post傳過來。通過status值來判斷是否支付成功'returnUrl' => $notifyUrl,//網頁跳轉地址，結果頁面會將返回參數通過get傳過來。通過status值來判斷是否支付成功'attachedData' => $attachedData， //攜帶的參數];ksort($data, SORT_STRING);reset($data);$options = '';$options2 = '';foreach ($data as $key => $value) {$options .= $key . '=' . $value .'&';///注意 參數還要用urlencode函數處理一下$options2 .= $key . '=' . urlencode($value) . '&';}$options = rtrim($options, '&');//存在轉義字符，那么去掉轉義if(get_magic_quotes_gpc()){$options = stripslashes($options);}$sign = md5($options . $mdKey);$options2 .= 'sign=' . urlencode($sign);///注意 參數還要用urlencode函數處理一下$url = 'https://qr-test2.chinaums.com/netpay-portal/webpay/pay.do?'.$options2;exit('<script>top.window.location.href=\'' . $url . '\'</script>');

2.支付結果查詢接口

$msgType = empty($msgType) ? 'query' : $msgType;$mdKey = 'fcAmtnx7MwismjWNhNKdHC44mNXtnEQeJkRrhKJwyrW2ysRR';$mid = '898340149000005';$tid = '88880001';$merOrderId = '3194' . 'SH20191120093138668264';$msgSrc = 'WWW.TEST.COM';$time = time();$notifyUrl = $_W['siteroot'] . '/addons/sz_yi/payment/yinlian/notify.php';$requestTimestamp = date('Y-m-d H:i:s',$time);$data = ['instMid' => 'YUEDANDEFAULT',//業務類型'merOrderId' => $merOrderId,//訂單號'mid' => $mid,//商戶號// 'msgSrc' => 'WWW.HANGZPXWH.COM',//消息來源'msgSrc' => $msgSrc,//消息來源'msgType' => $msgType,//消息類型'requestTimestamp' => $requestTimestamp,//報文請求時間'tid' => $tid,//終端號];ksort($data, SORT_STRING);reset($data);$options = '';$options2 = '';foreach ($data as $key => $value) {$options .= $key . '=' . $value .'&';}$options = rtrim($options, '&');//存在轉義字符，那么去掉轉義if(get_magic_quotes_gpc()){$options = stripslashes($options);}$sign = md5($options . $mdKey);$data['sign'] = $sign;$ch = curl_init();///json 格式 請求$data = json_encode($data);$timeout = 5;curl_setopt($ch, CURLOPT_URL, 'https://qr-test2.chinaums.com/netpay-route-server/api/');curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);// dump(123);die;curl_setopt($ch, CURLOPT_POSTFIELDS, ($data));curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);//設置header信息application/x-www-form-urlencoded;charset=utf-8 application/jsoncurl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data)));curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$output = curl_exec($ch);curl_close($ch);$output = json_decode($output);

3.訂單退款接口

$msgType = empty($msgType) ? 'refund' : $msgType;$instMid = 'YUEDANDEFAULT';//業務類型$mdKey = 'fcAmtnx7MwismjWNhNKdHC44mNXtnEQeJkRrhKJwyrW2ysRR';$mid = '898340149000005';$tid = '88880001';$merOrderId = '3194SH2030erererere6666699';//訂單號$msgSrc = 'WWW.TEST.COM';$time = time();$notifyUrl = $_W['siteroot'] . '/addons/sz_yi/payment/yinlian/notify.php';$requestTimestamp = date('Y-m-d H:i:s',$time);$data = ['instMid' => $instMid,//業務類型'merOrderId' => $merOrderId,//訂單號'mid' => $mid,//商戶號'msgSrc' => $msgSrc,//消息來源'msgType' => $msgType,//消息類型'requestTimestamp' => $requestTimestamp,//報文請求時間'tid' => $tid,//終端號'refundAmount' => 1,//退款金額'refundDesc' => '測試',//退款說明];ksort($data, SORT_STRING);reset($data);$options = '';$options2 = '';foreach ($data as $key => $value) {$options .= $key . '=' . $value .'&';}$options = rtrim($options, '&');//存在轉義字符，那么去掉轉義if(get_magic_quotes_gpc()){$options = stripslashes($options);}$sign = md5($options . $mdKey);$data['sign'] = $sign;$ch = curl_init();///json 格式 請求$data = json_encode($data);$timeout = 5;curl_setopt($ch, CURLOPT_URL, 'https://qr-test2.chinaums.com/netpay-route-server/api/');curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, ($data));curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);//設置header信息application/x-www-form-urlencoded;charset=utf-8 application/jsoncurl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data)));curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$output = curl_exec($ch);curl_close($ch);$output = json_decode($output);

調試
若不知道支付結果通知地址返回的參數，可以通過寫文件的方式來觀看返回的參數結果

$myfile = fopen("./notify.txt", "w") or die("Unable to open file!"); //創建或打開文件$post2 = json_encode($post);//根據通知地址返回的是get還是post方式 fwrite($myfile, $post2); fclose($myfile); // 關閉文件

(1)當notify.php 文件代碼，不執行時，可以將returnUrl的路徑=notifyUrl的路徑，觀看是否為路徑錯誤，或是否為notify.php因代碼錯誤而無法執行。
(2)若因notify.php代碼錯誤而無法執行。可以通過瀏覽器訪問notifyUrl路徑來觀看notify.php是否是代碼錯誤，而無法執行
