  • [Abp vNext微服务实践]

    简介:

    Vue Element Admin是基于vue、element ui开发的后台管理ui,abp vNext是abp新一代微服务框架。本篇将会介绍如何改造Vue Element Admin权限验证并接入abp vNext的微服务权限模块。上篇已经介绍过Vue Element Admin登录过程,并实现了假登录,本篇将介绍Vue Element Admin(后称Admin)实现登录权限验证。

    Vue Element Admin权限验证代码分析

    Admin在permission.js实现了全局登录验证,主要代码如下:

      const hasToken = getToken()
    
      if (hasToken) {
        if (to.path === '/login') {
          // if is logged in, redirect to the home page
          next({ path: '/' })
          NProgress.done()
        } else {
          // determine whether the user has obtained his permission roles through getInfo
          const hasRoles = store.getters.roles && store.getters.roles.length > 0
          if (hasRoles) {
            next()
          } else {
            try {
              // get user info
              var user = await store.dispatch('user/getInfo')
              // note: roles must be a object array! such as: ['admin'] or ,['developer','editor']
              const { roles } = await store.dispatch('user/getPermissions', user.sub)
    
              // generate accessible routes map based on roles
              const accessRoutes = await store.dispatch('permission/generateRoutes', roles)
    
              // dynamically add accessible routes
              router.addRoutes(accessRoutes)
    
              // hack method to ensure that addRoutes is complete
              // set the replace: true, so the navigation will not leave a history record
              next({ ...to, replace: true })
            } catch (error) {
              // remove token and go to login page to re-login
              await store.dispatch('user/resetToken')
              Message.error(error || 'Has Error')
              next(`/login?redirect=${to.path}`)
              NProgress.done()
            }
          }
        }
      } 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()
        }
      }

    分析代码得知在访问Admin时会首先获取token,如果token不存在会直接跳转登录,如果token存在会判断当前路由,如果路由指向login则直接进入首页。进入首页前会判断是否获取用户权限,如果没有则重新获取用户权限。主要改造在:

    const { roles } = await store.dispatch('user/getPermissions', user.sub)
    getPermissions代码如下:
      getPermissions({ commit }, sub) {
        return new Promise((resolve, reject) => {
          var params = {}
          params.providerName = 'User'
          params.providerKey = sub
          axiosMethods.getPermissions('/api/abp/application-configuration', params)
            .then(response => {
              const data = {}
              data.roles = []
    
    

           for(var role in response.auth.grantedPolicies){
             data.roles.push(role)
           }

    if (!data.roles || data.roles.length <= 0) {
                reject('getInfo: roles must be a non-null array!')
              }
              commit('SET_ROLES', data.roles)
              resolve(data)
            })
        })
      }

    代码分析:通过user的token信息请求/api/abp/application-configuration接口,获取权限后返回数组data。permission.js根据返回的roles动态挂载路由,此时权限改造就完成了,下面在权限测试页面进行测试。

    修改权限测试页面路由配置如下:

     登录后菜单如下:

    总结

    登录、权限验证改造完毕后在菜单中加入系统管理---用户、角色管理后就可以开始业务开发了。
