vue-element-admin改造步骤

一. 改为放温暖单点登录页面方式登录；

1. src/store/modules/user.js 增加setSSOUserToken方法

const actions = {
  // user login
  login({ commit }, userInfo) {
    const { username, password } = userInfo
    return new Promise((resolve, reject) => {
      login({ username: username.trim(), password: password }).then(response => {
        const { data } = response
        commit('SET_TOKEN', data.token)
        setToken(data.token)
        resolve()
      }).catch(error => {
        reject(error)
      })
    })
  },

  setSSOUserToken({ commit }, ssouserToken) {
    commit('SET_TOKEN', ssouserToken )
    setToken(ssouserToken)
  }
}

2. src/permission.js 修改判定条件，跳转至单点登录页面，并且截取返回的url，获取token，处理url，跳转至目标页面

import router from './router'
import store from './store'
import { Message } from 'element-ui'
import NProgress from 'nprogress' // progress bar
import 'nprogress/nprogress.css' // progress bar style
import { getToken, setToken } from '@/utils/auth' // get token from cookie
import getPageTitle from '@/utils/get-page-title'
import { getQueryString, param2Obj, getQueryObject } from '@/utils'

NProgress.configure({ showSpinner: false }) // NProgress Configuration

const whiteList = ['/login', '/auth-redirect'] // no redirect whitelist

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 {
      // 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
          // note: roles must be a object array! such as: ['admin'] or ,['developer','editor']
          const { roles } = await store.dispatch('user/getInfo')

          // 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()
      // 获取token
      const token = getQueryString('SSOUserToken')
      const token2 = param2Obj(window.location.href)
      const token3 = getQueryObject(window.location.href)
      if (token) {
        store.dispatch('user/setSSOUserToken', decodeURIComponent(token))
        // setToken(decodeURIComponent(token))
        window.location.href = window.location.href.split("?")[0]
      } else {
        // token不存在，跳转单点登录页面
        window.location.href = 'https://erpportal.ztzs.cn/sso/account/CheckToken/?LoginCallback=' + window.location.href
      }

    }
  }
})

router.afterEach(() => {
  // finish progress bar
  NProgress.done()
})
