小程序app.js使用以下代码：
App({
globalData: {
selectGoods: [], //购物车商品
topListInfo: [],
cateGoods: [],
cateGoods2: [],
httpInfo: "https://www.test.com/image/"
},
appData: {
customerInfo: null
},
onLaunch: function () {
//生成首页带参数二维码
wx.request({
url: "http://localhost/test/index.php?route=weixinprogram/qrcode/index",
success: function (res) {
console.log(res.data);
}
})
}
});
php后端代码：
