特别说明，当面付返回二维码，直接打开手机客户单。
wap支付，引用了支付宝提供的sdk,请自行下载：https://docs.open.alipay.com/203/105910/
vendor('Alipay.wappay.buildermodel.AlipayTradeWapPayContentBuilder');
$payRequestBuilder = new \AlipayTradeWapPayContentBuilder();
$payRequestBuilder->setSubject($this->order_desc);
$payRequestBuilder->setOutTradeNo($this->order_id);
$payRequestBuilder->setTotalAmount($this->order_money);
$payRequestBuilder->setTimeExpress($timeout_express);
vendor('Alipay.wappay.service.AlipayTradeService');
$payResponse = new \AlipayTradeService($config);
return $payResponse->wapPay($payRequestBuilder,$config['return_url'],$config['notify_url']);
下载的sdk，放到vendor下面即可使用，另需要修改sdk/AopSdk.php 16行。修改代码如下：
if (!defined("AOP_SDK_WORK_DIR"))
{
define("AOP_SDK_WORK_DIR", dirname(__FILE__) . "/tmp/");
}
不然会报错的哦！
完成上述步骤就可以直接使用了，直接代码里面引用(当面付)：
$pay = new \payment\Alipay($alipay, $param);
$data = $pay->pay();
if($data['code'] == 1){
header("Location:".$data['data']['code_url']);
exit;
}else{
echo $data['msg'];
}
大功告成！
