vue_admin_template改成动态菜单的问题

[aierda]

小弟我从网上下载了vue_admin_template项目，希望通过它来做项目的，
里面的菜单是写死的，我想通过调用api的形式，根据用户角色权限动态
生成权限菜单。我参照了网上好几个关于动态生成菜单的文章，但是我
我搞了好几天，怎么弄都不能成功，最后变动左侧菜单栏还是一片空白。
请各位大哥指点，手头是能够提供相关的参考资料或代码片断，不胜感激！

看看你的 生成菜单的代码~

@aierda 可以看一下后端返回的数据么

permission.js 里面的代码片断

router.beforeEach(async(to, from, next) => {
  // start progress bar
  NProgress.start()

  // set page title
  document.title = getPageTitle(to.meta.title)

  // determine whether the user has logged in
  const hasToken = getToken()
  if (hasToken) {
    if (to.path === '/login') {
      // if is logged in, redirect to the home page
      next({ path: '/' })
      NProgress.done()
    } else {
      const hasGetUserInfo = store.getters.name
      if (!hasGetUserInfo) {
        store.dispatch('user/getInfo').then(() => {
          // initMenu(router, data.routerDtos)
          router.addRoutes(store.getters.addRouters) // 动态添加可访问路由表
          next({ ...to, replace: true }) // hack方法 确保addRoutes已完成 ,set the replace: true so the navigation will not leave a history record
        })
      } else {
        next()
      }
    }
  } else {
    /* has no token*/

    if (whiteList.indexOf(to.path) !== -1) {
      // in the free login whitelist, go directly
      next()
    } else {
      // other pages that do not have permission to access are redirected to the login page.
      next(`/login?redirect=${to.path}`)
      NProgress.done()
    }
  }
})

我基本上弄好了，折腾死我了

[白番茄的爱--]

能发一份登录动态获取路由的源码吗，我这里路由这些都挂载不上

[低調的D吖]

tell me how to resolve

可以把你这个前端项目借我学学么
