用织梦做了个旅游网站，客户要求财付通支付，上网找了下 不是要买就是要钱，只有自己写了。

代码：

复制代码 代码如下:
<?php
if(!defined('DEDEINC')) exit('Request Error!');
/**
*财付通接口类
*/
class tenpay
{
var $dsql;
var $mid;
var $reqURL_onLine = "http:///gateway/pay.htm?'.$param. '&sign='.$sign.'"><button>立即使用财付通支付</button></a></div>';
return $button;

require_once DEDEINC.'/shopcar.class.php';
$cart = new MemberShops();
$cart->clearItem();
$cart->MakeOrders();
return $button;
}
/**
* 响应操作
*/
function respond()
{

$code = preg_replace( "#[^0-9a-z-]#i", "", $_GET['code'] );
require_once DEDEDATA.'/payment/'.$code.'.php';
$attach = $_GET['attach'];
$trade_state = $_GET['trade_state'];
$total_fee = $_GET['total_fee'];
$out_trade_no = trim($_GET['out_trade_no']);
if(preg_match ("/S-P[0-9]+RN[0-9]/",$order_sn)) {
//检查支付金额是否相符
$row = $this->dsql->GetOne("SELECT * FROM #@__shops_orders WHERE oid = '{$order_sn}'");
if ($row['priceCount'] != $_GET['total_fee'])
{
return $msg = "支付失败，支付金额与商品总价不相符!";
}
$this->mid = $row['userid'];

ksort($_GET);
reset($_GET);
$sign = '';
foreach ($_GET AS $key => $val)
{
if("" != $val && "sign" != $key && $key != 'code') {
$sign .= "$key=$val&";
}
}
