这段代码定义了一个 `RoleBean` 数组,其中包含三个不同的角色:`admin`、`editor` 和 `visitor`,每个角色都有一个 `key`、`name`、`description` 和 `routes` 属性。`routes` 属性是一个嵌套路由数组,用于定义角色可以访问的页面和路由。管理员角色可以访问所有页面,编辑角色可以访问除权限页面之外的所有页面,而访客角色只能访问主页和文档页面。`routes` 数组通过过滤掉权限页面来定义编辑角色的访问权限。

const getters = { sidebar: state => state.app.sidebar, size: state => state.app.size, device: state => state.app.device, dict: state => state.dict.dict, visitedViews: state => state.tagsView.visitedViews, cachedViews: state => state.tagsView.cachedViews, token: state => state.user.token, avatar: state => state.user.avatar, name: state => state.user.name, introduction: state => state.user.introduction, roles: state => state.user.roles, permissions: state => state.user.permissions, permission_routes: state => state.permission.routes, topbarRouters:state => state.permission.topbarRouters, defaultRoutes:state => state.permission.defaultRoutes, sidebarRouters:state => state.permission.sidebarRouters, } export default getters
这段代码是一个 Vuex 中的 getter,用于从 state 中获取数据。getter 可以被认为是 store 的计算属性。它们的用途是派生一些状态,用于计算和返回数据,而不是直接在 state 中存储。这有助于保持状态的一致性和可维护性。
这个 getter 中定义了一系列属性的获取方法,包括 `sidebar`、`size`、`device`、`dict`、`visitedViews`、`cachedViews`、`token`、`avatar`、`name`、`introduction`、`roles`、`permissions`、`permission_routes`、`topbarRouters`、`defaultRoutes`、`sidebarRouters`。这些属性都对应着 state 中的不同字段。以 `sidebar` 为例,它返回 `state.app.sidebar`,也就是 app 模块下的 sidebar 字段的值。其他属性的获取方法类似。
最后,这个 getter 通过 `export default` 导出,以便在其他组件或模块中使用。
DeveloperError: key is required to be a string or number.
This error message usually indicates that you are trying to use an object as a key in a Map or a property in an object, but the key needs to be a string or a number.
For example, if you have an object like this:
```
const obj = {
{a: 1}: 'value'
}
```
and you try to use `obj` as a key in a Map, you will get this error because the Map key must be a string or a number.
To fix this error, make sure that you are using strings or numbers as keys in your Maps or objects. If you need to use an object as a key, you can convert it to a string using `JSON.stringify()` or a similar method.
