2. 页面执行代码

<?php
include_once "class/weixiaodian.php";
$wXd = new wXd();
echo "<pre>";
//查询全部商品
$wXd->gStateProduct();
//获取订单信息
$wXd->gOrderInfo("12963133879983601645");
//关闭订单
$wXd->sOrderClose("12963133879983600740");
//发货订单设置
$data["need_delivery"] = "1";
$data["order_id"] = "12963133879983600667";
$data["delivery_company"] = "059Yunda";
$data["delivery_track_no"] = "1000464090326";
$wXd->sOrderDelivery($data);
//获取所有订单
$wXd->gOrderAll();
echo "</pre>";
