??总体思路
1.显示别人的空间
? a.地址栏中如有userid?则显示对应的用户数据
?2.显示自身空间
?????a.如果没有userid??则默认显示自己信息
?????b.如果在菜谱中?点击自己?也是有userid传递
????c.通过判断是否为自己的?如果是，不需要后端拿,登录时，个人信息
?3.代码展示

?注意：watch 中用到了初始化监听
监听分为初始化监听，和深度监听
属性immediate和deep
immediate与handler
watch的特点是当被监听变量变化时才是执行函数，而在初始化（只有变化才会执行）的时候并不会执行，使用handler与immediate的作用是
当immediate为false时，与之前的效果相同
deep就是深入观察，监听器会一层层的往下遍历，给对象的所有属性都加上这个监听器，但是这样性能开销就会非常大了，任何修改obj里面任何一个属性都会触发这个监听器里的 handler。?
2.点击 作品? 粉丝? 关注? 收藏 进行数据加载和显示
