            require_once("./include/ext/alipayconfig.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 = "http://www.***.com/index.php/alipaynotify.html";
        	//需http://格式的完整路径，不能加?id=123这类自定义参数
        	
        	//页面跳转同步通知页面路径
        	$return_url = "http://www.***.com/index.php/member/alipayreturn.html";/
        	//需http://格式的完整路径，不能加?id=123这类自定义参数，不能写成http://localhost/
        	
        	//商户订单号
        	$out_trade_no = $order_sn['order_sn'];
        	//商户网站订单系统中唯一订单号，必填
        	
        	//订单名称
        	$subject = $order_sn['order_sn'];
        	//必填
    	
        	//付款金额
        	$total_fee = $order_sn['goods_amount'];

        	$show_url = 'http://www.***.com/index.php/member/myclass.html';
        	//需以http://开头的完整路径，例如：http://www.商户网址.com/myorder.html
        	
 
        	 
        	$alipaySubmit = new AlipaySubmit($alipay_config);
        	//防钓鱼时间戳
        	$anti_phishing_key = '';
        	//若要使用请调用类文件submit中的query_timestamp函数
        	
        	//客户端的IP地址
        	$exter_invoke_ip = get_client_ip();
 
        	//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']),
        			"seller_email" => trim($alipay_config['seller_email']),
        			"payment_type"	=> $payment_type,
        			"notify_url"	=> $notify_url,
        			"return_url"	=> $return_url,

        	);
        	
        	//建立请求
        	
        	$html_text = $alipaySubmit->buildRequestForm($parameter,"get", "confirm");
        	echo $html_text;
            
        }

同步方法:

//验证支付结果
    public function alipayreturn() {
        if($_GET['trade_status']=="TRADE_SUCCESS" || $_GET['trade_status']=="TRADE_FINISHED") {//验证成功
            $condition['order_sn'] = $_GET['out_trade_no'];
            $condition['user_id'] = $_SESSION['user']['uid'];
            
            $order = $this->model->table('member_order')->where($condition)->find();
            
            $this->redirect(__APP__."/member/paysuccess/".$order['order_id'].".html");
        }
        else {
          $this->success("支付失败！",__APP__."/member/myclass.html");
        }
    }

异步方法

//验证支付结果
    public functionalipaynotify() {
        //业务逻辑
    }
