同学你好

就是我说的拼写错误啊。。。

两个地方：

store.ts 第 93 行：

1	axios.defaults.headers.common.Authorization = `Bearer ${token}`

App.vue 第 47行

1	axios.defaults.headers.common.Authorization = `Bearer ${token}`

都修改了就好了，亲测可用

同学你好

看起来是拼写错误：Authrization

应该是：Authorization

  没有拼写错误

  同学你好 之前我看源代码的时候好像是有拼写错误的 如果还没有解决的话 请把源代码（git）发给我吧，我在本地帮你看一下
