1、几个主要的核心文件

//app.js
App({
  onLaunch: function () {
    //调用API从本地缓存中获取数据
    var logs = wx.getStorageSync('logs') || []
    logs.unshift(Date.now())
    wx.setStorageSync('logs', logs)
  },
  getUserInfo:function(cb){
    var that = this
    if(this.globalData.userInfo){
      typeof cb == "function" && cb(this.globalData.userInfo)
    }else{
      //调用登录接口
      wx.login({
        success: function () {
          wx.getUserInfo({
            success: function (res) {
              that.globalData.userInfo = res.userInfo
              typeof cb == "function" && cb(that.globalData.userInfo)
            }
          })
        }
      })
    }
  },
  globalData:{
    userInfo:null
  }
})

//app.json
{
  "pages":[
    "pages/index/index",
    "pages/logs/logs"
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "WeChat",
    "navigationBarTextStyle":"black"
  }
}

/**app.wxss**/
.container {
  height: 100%;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: space-between;
  padding: 200rpx 0;
  box-sizing: border-box;
}

2、素材圈官网微信小程序主要目录和文件

<!--index.wxml-->
<view class="container">
  <view  bindtap="bindViewTap" class="userinfo">
    <a href="http://www.sucaiq.com" class="userinfo-nickname">你好，程序员员。</a>
    <a href="http://www.sucaiq.com" class="userinfo-nickname"><image class="userinfo-avatar" src="http://www.sucaiq.com/Public/images/logo.png" background-size="cover"></image></a>
  </view>
  <view class="usermotto">
    <a href="http://www.sucaiq.com" class="userinfo-nickname">素材圈官网</a>

//index.js
//获取应用实例
var app = getApp()
Page({
  data: {
    motto: 'Hello World',
    userInfo: {}
  },
  //事件处理函数
  bindViewTap: function() {
    wx.navigateTo({
      url: '../logs/logs'
    })
  },
  onLoad: function () {
    console.log('onLoad')
    var that = this
    //调用应用实例的方法获取全局数据
    app.getUserInfo(function(userInfo){
      //更新数据
      that.setData({
        userInfo:userInfo
      })
    })
  }
})

/**index.wxss**/
.userinfo {
  display: flex;
