vue中怎么根据用户权限动态添加路由

这篇文章主要介绍"vue中怎么根据用户权限动态添加路由"，在日常操作中，相信很多人在vue中怎么根据用户权限动态添加路由问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"vue中怎么根据用户权限动态添加路由"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

知识点

路由守卫（使用了前置守卫）：根据用户角色判断要添加的路由
vuex：保存动态添加的路由

难点

每次路由发生变化时都需要调用一次路由守卫，并且store中的数据会在每次刷新的时候清空，因此需要判断store中是否有添加的动态路由。
（若没有判断 则会一直添加 导致内存溢出）

根据角色判断路由
过滤动态路由 判断每条路由角色是否与登录传入的角色一致
