如果缓存中有对象存在，点击就不会报错
不知道你们有没有遇到这样

const postsCollected = {...this.data._postsCollected}
这样就可以了。

到了零晨5点，查了资料才知道怎么改
onCollect(event){
var postsCollected = this.data._postsCollected
//判断postsCollected的空对象去做的事情
if(postsCollected == ''){
const postsCollected = {}
postsCollected[this.data._pid] = !this.data.collected
this.setData({
collected:!this.data.collected
})
wx.setStorageSync('posts_collected', postsCollected)
}else{
const postsCollected = this.data._postsCollected
postsCollected[this.data._pid] = !this.data.collected
this.setData({
collected:!this.data.collected
})
wx.setStorageSync('posts_collected', postsCollected)
}
},

if (postCollected == '') {
this.data._postCollected = {}
} else {
