```js
npm install vuex@next --save
```

* #### 管理用户信息

> 创建 store 文件夹： src/store/index.js

```js
import { createStore } from 'vuex'

// 创建一个新的 store 实例
const store = createStore({
    state() {
        return {
            // 用户信息
            user: {}
        }
    },
    mutations: {
        // 记录用户信息
        SET_USERINFO(state, user) {
            state.user = user
        }
    }
})

export default store


```

* ### 注册到入口文件

> main.js

```js
...略
import store from './store'  // +

app.use(store)               // +
```

* #### 修改 login.vue

> 登录获取用户信息，保存到 store 里

```js
...略
import { useStore } from 'vuex'
const store = useStore()


...略

            // 测试携带 Toekn 访问自己个人信息
            getinfo().then(res2=>{
                store.commit("SET_USERINFO",res2) // +
                console.log(res2)
            })
```

* #### 测试渲染保存的信息

> index.vue

```js
<template>
    <div>
        后台首页

        {{ $store.state.user }}
    </div>
</template>

<script setup></script>
