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!
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
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
