1 开发前准备 先和银联手机支付签约，他们会给你测试的证书已经手机客户端的控件

2  将包里的文件(TESTMERCHANT.p12)经过openssl生成的密钥文件TESTMERCHANT.pm 默认密码是 1

3 PHP端程序

下订单程序

/*

* 银联支付

* */

//wap下订单接口(需要验证签名)

public function wapsendAction() {

header("Content-Type:text/html; charset=utf-8");

$request = $this->getRequest();

if(isset($_SESSION['uid'])){

if($request->isPost()){

$uid=intval($_SESSION['uid']);

$money = intval($request->getPost(money));//金额以元为单位

$beans = $money;

$arraymoney=array("1","10","30","100");

if(!in_array($money,$arraymoney)){

echo '1';//金额不对

exit();

}

}else{

echo '2';//不是POST请求

exit();

}

$payaction = new PayAction();

$rid = $payaction->insertRecharge($uid, 36, $money, $beans);

if($rid) {

$orderTime=date('YmdHis'); //交易开始日期时间

//$rid='00000123';//订单

$rid=str_pad($rid,'8','0',STR_PAD_LEFT);

//$money='000000000030';//金额str_pad(string,length,pad_string,pad_type)

$money= str_pad($money*100,'12','0',STR_PAD_LEFT);

//$bz='156';//币种

$terminal='00000001';//pos机

$shanghu='100011000110195';//商户代码

$shanghumc='我在找你';//商户名称

$string=$orderTime.$rid.$money.$terminal.$shanghu.$shanghumc;

$fp = fopen(ROOT_ACTION.'quickpay/TESTMERCHANT.pem', "r");

$priv_key = fread($fp, 8192);

fclose($fp);

$pkeyid = openssl_get_privatekey($priv_key);

openssl_sign($string, $signature, $pkeyid);

$len = strlen($signature);

$hexArray = "0123456789abcdef";

$str = $signature;

$result = "";

for($i=0;$i

if(ord($str[$i]) >= 128){

$byte = ord($str[$i]) - 256;

}else{

$byte =  ord($str[$i]);

}

$bytes[] = $byte ;

$byte = $byte & 0xff;

$result .= $hexArray[$byte >> 4];

$result .= $hexArray[$byte & 0xf];

}

echo '<?xml version="1.0" encoding="UTF-8" standalone="yes"?>'.$orderTime.''.$beans.'块钱订单'.$money.''.$result.'';

}else{

$payaction = new PayAction();

$str = '银联wap支付下订单失败uid='.$uid.'money='.$money.'rid='.$rid;

$payaction->Insert_errorpay($str,1,0);//1为银联1 为下订单失败

echo '3';//订单验证签名失败

exit;

}

}else{

echo '4';//登录后再下订单

exit();

}

}

现在再提供一个回调的函数就可以了。

public function wapback_notifyAction() {

$request = $this->getRequest();

if($request->isPost()){

$arr_ret = file_get_contents("php://input");

$payaction = new PayAction();

$xml = new SimpleXMLElement($arr_ret);

$orderid=$this->getAttr($arr_ret,'order') ;//获取订单id

$submitTime=$this->getDataForXML($arr_ret,'/cupMobile/transaction/submitTime');//获取交易时间

$moeney=$this->getDataForXML($arr_ret,'/cupMobile/transaction/billAmount');//获取金额

$accountNumber1=$this->getDataForXML($arr_ret,'/cupMobile/transaction/accountNumber1');//获取支付卡

$settleDate=date('Ymd'); //交易开始日期时间

$payaction->insertPayQQ(1,1,$arr_ret.'orderid'.$orderid['id']);

if($orderid['id']>0){

$orderNumbe=substr($orderid['id'],'2');

$payaction->updateRechargeStatus($orderNumbe);

echo '<?xml version="1.0" encoding="UTF-8"?>'.$submitTime.''.$submitTime.''.$moeney.''.$accountNumber1.'000000001'.$moeney.''.$settleDate.'';

}

}

}

这样就好了 另外附带2个xml操作函数

//xml获取属性值

function getAttr($str , $tag) {

preg_match_all("/(?:]*)>/im" , $str , $ary);

if(is_array($ary[1])) {

preg_match_all('/([a-zA_Z0-9]+?)\s*?(?:=)\s*?(?:[\'"]?)([a-zA_Z0-9_\-\.]*?)(?:[\'"])/im' , $ary[1][0] , $a);

for($i = 0 , $j = count($a[1]) ; $i < $j ; ++$i) {

$v[$a[1][$i]] = $a[2][$i];

}

return $v;

}

}

//xml获取指定节点的元素值

function getDataForXML($res_data,$node)

{

$xml = simplexml_load_string($res_data);

$result = $xml->xpath($node);

while(list( , $node) = each($result))

{

return $node;

}

}
