BUG1 : 路由跳转问题

访问错误路由： 已登录用户返回404，未登录用户返回登录页面

Route/index.js

路由守卫增加判断

router.beforeEach((to, from, next) => {
  localStorage.setItem("currentPathName", to.name)  // 设置当前的路由名称
  store.commit("setPath")

  // 未找到路由的情况
  if (!to.matched.length) {
    const storeMenus = localStorage.getItem("menus")
    if (storeMenus) {
      next("/404")
    } else {
      // 跳回登录页面
      next("/login")
    }
  }
  // 其他的情况都放行
  next()

})

角色管理界面分配菜单按钮点击没反应

解决办法1

解决办法2

新建菜单访问404问题。

●新建一个Vue页面
●给页面加一个菜单
●给管理员分配菜单
●重新登录
●点击刚才分配的菜单
●出现404

解决方法：
// 在router的 index.js中提供一个重置路由的方法

export const resetRouter = () => {
  router.matcher = new VueRouter({
    mode: 'history',
    base: process.env.BASE_URL,
    routes
  })
}

然后在 store的index.js的logout()中调用一下这个重置路由的方法即可

logout() {
    // 清空缓存
    localStorage.removeItem("user")
    localStorage.removeItem("menus")
    router.push("/login")

    // 重置路由
    resetRouter()
}

增加修改密码
