tp框架中集成支付宝的功能，将支付宝的demo例子存在到下图位置\Extend\Vendor\Alipay

生成支付订单

/**

* 支付订单

*/

public function pay() {

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

$id = I('post.oid','', 'htmlspecialchars');

$DAO = M('order');

$order = $DAO->where("id=".$id)->find();

$error = "";

if(!isset($order)){

$error = "订单不存在";

}else if($order['PaymentStatus'] == 1){

$error = "此订单已经完成，无需再次支付！";

} else if($order['PaymentStatus'] == 2){

$error = "此订单已经取消，无法支付，请重新下单！";

}

if($error != ""){

$this->_FAIL("系统错误",$error,$this->getErrorLinks());

return ;

}

$payType = I('post.payType','', 'htmlspecialchars');

#支付宝

if($payType == 'alipay'){

$this->payWithAlipay($order);

}

　　支付订单提交

/**

* 以支付宝形式支付

* @param unknown_type $order

*/

private function payWithAlipay($order){

//引入支付宝相关的文件

require_once(VENDOR_PATH."Alipay/alipay.config.php");

require_once(VENDOR_PATH."Alipay/lib/alipay_submit.class.php");

//支付类型

$payment_type = "1";

//必填，不能修改

//服务器异步通知页面路径

$notify_url = C("HOST")."index.php/Alipay/notifyOnAlipay";

//页面跳转同步通知页面路径

$return_url = C("HOST")."index.php/Pay/ok";

//卖家支付宝帐户

$seller_email = $alipay_config['seller_email'];

//必填

//商户订单号, 从订单对象中获取

$out_trade_no = $order['OrderNum'];

//商户网站订单系统中唯一订单号，必填

//订单名称

$subject = "物流服务";

//必填

//付款金额

#正常金额

$price = $order['Price'];

#测试金额

#$price = 0.1;

//必填

$body = $subject;

//商品展示地址

$show_url = C('HOST');

//构造要请求的参数数组，无需改动

$parameter = array(

"service" => "create_direct_pay_by_user",

"partner" => trim($alipay_config['partner']),

"payment_type" => $payment_type,

"notify_url" => $notify_url,

"return_url" => $return_url,

"seller_email" => $seller_email,

"out_trade_no" => $out_trade_no,

"subject" => $subject,

"total_fee" => $price,

"body" => $body,

"show_url" => $show_url,

"_input_charset" => trim(strtolower($alipay_config['input_charset']))

);

Log::write('支付宝订单参数：'.var_export($parameter,true),Log::DEBUG);

//建立请求

$alipaySubmit = new AlipaySubmit($alipay_config);

$html_text = $alipaySubmit->buildRequestForm($parameter,"get", "去支付");

echo $html_text;

}

　　支付宝回调接口

<?php
/**
* 支付宝回调接口
*/
class AlipayAction extends Action {
    
    /**
      * 支付宝异步通知
      */
    public function notifyOnAlipay(){
        Log::write("notify: ".print_r($_REQUEST, true),Log::DEBUG);
        require_once(VENDOR_PATH."Alipay/alipay.config.php");
        require_once(VENDOR_PATH."Alipay/lib/alipay_notify.class.php");
        $orderLogDao = M('orderlog');
         //计算得出通知验证结果
        $alipayNotify = new AlipayNotify($alipay_config);
        $verify_result = $alipayNotify->verifyNotify();
        Log::write('verify_result：'.var_export($verify_result,true),Log::DEBUG);
        if($verify_result) {//验证成功
            //商户订单号
            $out_trade_no = $_POST['out_trade_no'];
            //支付宝交易号
            $trade_no = $_POST['trade_no'];
            //根据订单号获取订单
            $DAO = M('order');
            $order = $DAO->where("OrderNum='".$out_trade_no."'")->find();
            //如果订单不存在，设置为0
            if(!isset($order)){
                $orderId = 0;
            }
            else{
                $orderId = $order['id'];
            }
            //交易状态
            $trade_status = $_POST['trade_status'];
            $log = "notify from Alipay, trade_status=".$trade_status." alipay sign=".$_POST['sign'].' price ='.$_POST['total_fee'] ;
            $orderLog['o_id'] = $orderId;
            if($_POST['trade_status'] == 'TRADE_FINISHED' || $_POST['trade_status'] == 'TRADE_SUCCESS') {
                #修改订单状态
                if ((float)$order['Price'] != (float)$_POST['total_fee']) {
                    $data['PaymentStatus'] = '2';    
                } else {
                    $data['PaymentStatus'] = '1';    
                }
                $DAO ->where('id='.$orderId)->save($data);
            }
               $orderLog['pay_id']  = $trade_no;
               $orderLog['pay_log'] = $log;
               $orderLog['pay_type'] = 'alipay';
               $orderLog['pay_result'] = 'success';
               
               $orderLogDao->add($orderLog);
            /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
            echo "success"; //返回成功标记给支付宝
        }
        else {
        //验证不通过时，也记录下来
            $orderLog['pay_log'] = "notify from Alipay, 但是验证不通过，sign=".$_POST['sign'];
            $orderLog['o_id'] = -1;
            $orderLog['pay_type'] = 'alipay';
               $orderLog['pay_result'] = 'fail';
            $orderLogDao->add($orderLog);
         
           //验证失败
           echo "fail";
        }
    }
}
