小程序生成携带参数二维码

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：

<?php

//测试生成小程序码

//url: 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wxdf2a75a443729375&secret=3a2f38a617f4a531235809846cfa1b3b',
