api.js中写入后端的 解密用户数据得到 unionid以及 获取微信 session info的接口（其他两个引入文件还没有细看..）

数据调用——获取计划列表

onLoad: function () {
        let that = this

        app.authReadyCallback = globalData=>{

            setTimeout(() => {
                console.log(globalData)

                wx.request({
                    url: 'http://popfeng.wechat.api.dev.juzigo.com:1088/api/tripcalendar/main/list-for-user',
                    header: {
                        "Content-Type": "application/x-www-form-urlencoded"
                    },
                    data: { unionid:globalData.sessionInfo.unionid },
                    method: "POST",
                    success: function (res) {
                        that.setData({
                            info: res.data.data.list
                        })
                    }
                })
            }, 300)
        }
        app.requestAuth()
    },
