微信小程序的登录允许拒绝

多次拒绝登录和允许登录

微信小程序的登录获取用户信息，是通过微信弹出窗口，用户可点击允许 和拒绝两个按钮，点击允许，则获取用户信息登录成功，若点击拒绝，则获取失败，可通过二次请求调用弹起获取用户信息窗口，如图所示。

具体代码如下：

//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);
    console.log('logs',logs);
  },
  getUserInfo:function(cb){
      var that = this;
     //调用登录接口
      function getOpenid(backMsg){
        that.globalData.userInfo = backMsg.userInfo;
        that.globalData.encryptedData = backMsg.encryptedData;
        that.globalData.iv = backMsg.iv;
