教程问题反馈：第4章 场景应用本地数据缓存
[代码]之前存储的sessionId数据为：[代码] [代码]
var expiredTime = +new Date() +1*24*60*60*1000[代码][代码][代码] [代码]之后读取的sessionId为： [代码] [代码] if (now - expiredTime <=1*24*60*60*1000) {
//以上应该是 if (now - expiredTime <0)[代码] [代码]
this.globalData.sessionId = sessionId
this.globalData.expiredTime = expiredTime
}
},
globalData: {
sessionId: null,
expiredTime: 0[代码]
