都知道，我们在写项目的时候，最想给自己项目增加实用性了，例如我们的头像上传以及个人的各种信息等等。我们刚刚已经做好了我们的上传接口，那么我们现在就趁热打铁，将我们的头像上传功能解决一下。
我们的个人信息界面由我们的头像以及我们的表格组成，那么就说明我们需要去获取我们用户的数据了
我们之前是做过用户数据存储的，就是利用token来将我们用户的数据存放在我们的浏览器里面，然后利用localStorage来查找出我们的用户数据。
对于头像上传，我们依然用到我们之前的接口和组件来实现该功能。

我们在我们的头部进行数据查询和引用，就是通过user，然后找到我们的头像的元素，最后进行展示
我们需要在我们的脚手架里面去获取用户User最新的数据，然后最后在我们的头部Header里面去进行引入并获取信息
