微信小程序做缓存处理

 根据当前时间作为判断依据,缓存数据


Page({
  data: {
   
  },
  
  onLoad: function () {
   
    
    //this.getNowTime()
    if(wx.getStorageSync("loaction_time")==this.getNowTime()){
      //读取缓存
       console.log("缓存地址");
        var datevalue=wx.getStorageSync("loaction");
        console.log(datevalue)
        
    }else{
      wx.removeStorageSync("loaction");
      //请求地址
      console.log("请求地址");
      var loactionname="bs";
      wx.setStorageSync("loaction",loactionname);
      wx.setStorageSync("loaction_time",this.getNowTime());
      var datevalue=wx.getStorageSync("loaction"); 
      console.log(datevalue)
    }
        
  },getNowTime: function() {
    var now = new Date();
    var year = now.getFullYear();
    var month = now.getMonth() + 1;
    var day = now.getDate();
    if(month < 10) {
      month = '0' + month;
    };
    if(day < 10) {
      day = '0' + day;
    };
    //  如果需要时分秒,就放开
    var h = now.getHours();
    var m = now.getMinutes();
    var s = now.getSeconds();
    //var formatDate = year + '-' + month + '-' + day + ' ' + h + ':' + m + ':' + s;
    var formatDate = year + '-' + month + '-' + day;
    //console.log('当前时间',formatDate)
    return formatDate;
  }

})
