Prepare

How to get PrivateKey, PublicKey, Cert ID:

0. Prepare cert.pfx and its password, verify_sign_acp.cer

1. Get Private Key
$ openssl pkcs12 -in cert.pfx  -nocerts -nodes | openssl rsa -out private_key.pem

2. Public key is verify_sign_acp.cer

3. Get Cert ID
$ openssl pkcs12 -in cert.pfx -clcerts -nokeys | openssl x509 -serial -noout // result hex eg: XXXXXXXXXX
$ visit https://lokielse.github.io/hex2dec //Convert hex to decimal online

Consume

$gateway    = Omnipay::create('UnionPay_Express');
$gateway->setMerId($config['merId']);
$gateway->setCertId($config['certId']);
$gateway->setPrivateKey($config['privateKey']); // path or content
$gateway->setReturnUrl($config['returnUrl']);
$gateway->setNotifyUrl($config['notifyUrl']);

$order = [
    'orderId'   => date('YmdHis'), //Your order ID
    'txnTime'   => date('YmdHis'), //Should be format 'YmdHis'
    'orderDesc' => 'My order title', //Order Title
    'txnAmt'    => '100', //Order Total Fee
];

//For PC/Wap
$response = $gateway->purchase($order)->send();
$response->getRedirectHtml();

//For APP
$response = $gateway->createOrder($order)->send();
$response->getTradeNo();

Return/Notify

$gateway    = Omnipay::create('UnionPay_Express');
$gateway->setMerId($config['merId']);
$gateway->setPublicKey($config['publicKey']); // path or content

$response = $gateway->completePurchase(['request_params'=>$_REQUEST])->send();

if ($response->isPaid()) {
    //pay success
}else{
    //pay fail
}

Query Order Status

$response = $gateway->query([
    'orderId' => '20150815121214', //Your site trade no, not union tn.
    'txnTime' => '20150815121214', //Order trade time
    'txnAmt'  => '200', //Order total fee
])->send();

var_dump($response->isSuccessful());
var_dump($response->getData());

Consume Undo

$response = $gateway->consumeUndo([
    'orderId' => '20150815121214', //Your site trade no, not union tn.
    'txnTime' => date('YmdHis'), //Regenerate a new time
    'txnAmt'  => '200', //Order total fee
    'queryId' => 'xxxxxxxxx', //Order total fee
])->send();

var_dump($response->isSuccessful());
var_dump($response->getData());

Refund

// 注意：
1. 银联退款时，必须加上 queryId, 
2. 作为商户生成的订单号orderId与退款时的订单号是不一样的。也就意味着退款时的订单号必须重新生成。
3. txnAmt 这个参数银联是精确到分的。直接返回元为单位的值，将会出现报错信息。
// get the queryId first
$response = $gateway->query([
    'orderId' => '20150815121214', //Your site trade no, not union tn.
    'txnTime' => '20150815121214', //Order trade time
    'txnAmt'  => 200 * 100, //Order total fee; notice that: you should multiply the txnAmt by 100 with the Unionpay gateway. Such as 200 * 100;
])->send();
$queryId = ($response->getData())['queryId'];
$response = $gateway->refund([
    'orderId' => '20150815121214', //Your site trade no, not union tn. notice: this orderId must not be the same with the order's created orderId.
    'txnTime' => date('YmdHis'), //Order trade time
    'txnAmt'  => 200 * 100, //Order total fee; notice that: you should multiply the txnAmt by 100 with the Unionpay gateway. Such as 200 * 100;
    'queryId' => $queryId
])->send();

var_dump($response->isSuccessful());
var_dump($response->getData());

File Transfer

$response = $gateway->fileTransfer([
    'txnTime'    => '20150815121214', //Order trade time
    'settleDate' => '0119', //Settle Date
    'fileType'   => '00', //File Type
])->send();

var_dump($response->isSuccessful());
var_dump($response->getData());
