[Abp vNext微服务实践] - vue-element-admin登录二

vue

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。
