照着视频敲了代码，还下载了老师的源码，把我自己写的js复制过去老师那边没报错，但是在我自己写的页面就会报错。我自己的写的postsCollected初始化直接是一个布尔值，而放在老师那边是一个对象，data数据一致，js一致，wxml一致。问题出在哪里啊
var postsData = require(’…/…/…/data/posts-data.js’);
Page({
data:{

},
onLoad:function(option){
var postId=option.id;
this.data.currentPostId = postId;
var postData = postsData.postList[postId];
this.setData({
postData:postData
})

var postsCollected = wx.getStorageSync('posts_collected');
console.log(postsCollected);
if(postsCollected){
  var postCollected = postsCollected[postId]
  if (postCollected){
    this.setData({
      collected: postCollected
    })
  }
  console.log(1);
}
else{
  var postsCollected={};
  postsCollected[postId]=false;
  wx.setStorageSync('posts_collected', postsCollected);
  console.log(2);
}

},
onCollectionTap:function(event){
var postsCollected=wx.getStorageSync(‘posts_collected’);
var postCollected = postsCollected[this.data.currentPostId];
//收藏变成为收藏，未收藏变成已收藏
postCollected = !postCollected;
postsCollected[this.data.currentPostId]=postCollected;
//更新文章是否收藏的缓存值
wx.setStorageSync(‘posts_collected’, postsCollected);

//更新数据绑定变量，从而实现切换图片
this.setData({
  collected:postCollected
})

}

})
