// nuxt.config.js
import hooks from './hooks'
export default {
  router: {
    base: '/portal'
  hooks: hooks(this)
然后，创建一些文件;
hooks/index.js, Hooks 模块
// file: hooks/index.js
import render from './render'
export default nuxtConfig => ({
  render: render(nuxtConfig)
hooks/render.js, 渲染 hook
// file: hooks/render.js
import redirectRootToPortal from './route-redirect-portal'
export default nuxtConfig => {
  const router = Reflect.has(nuxtConfig, 'router') ? nuxtConfig.router : {}
  const base = Reflect.has(router, 'base') ? router.base : '/portal'
  return {
     * 'render:setupMiddleware'
     * {@link node_modules/nuxt/lib/core/renderer.js}
    setupMiddleware(app) {
      app.use('/', redirectRootToPortal(base))
hooks/route-redirect-portal.js, 中间件本身
// file: hooks/route-redirect-portal.js
 * Nuxt middleware hook to redirect from / to /portal (or whatever we set in nuxt.config.js router.base)
 * Should be the same version as connect
 * {@link node_modules/connect/package.json}
import parseurl from 'parseurl'
 * Connect middleware to handle redirecting to desired Web Applicatin Context Root.
 * Notice that Nuxt docs lacks explaning how to use hooks.
 * This is a sample router to help explain.
 * See nice implementation for inspiration:
 * - https://github.com/nuxt/nuxt.js/blob/dev/examples/with-cookies/plugins/cookies.js
 * - https://github.com/yyx990803/launch-editor/blob/master/packages/launch-editor-middleware/index.js
 * [http_class_http_clientrequest]: https://nodejs.org/api/http.html#http_class_http_clientrequest
 * [http_class_http_serverresponse]: https://nodejs.org/api/http.html#http_class_http_serverresponse
 * @param {http.ClientRequest} req Node.js internal client request object [http_class_http_clientrequest]
 * @param {http.ServerResponse} res Node.js internal response [http_class_http_serverresponse]
 * @param {Function} next middleware callback
export default desiredContextRoot =>
  function projectHooksRouteRedirectPortal(req, res, next) {
    const desiredContextRootRegExp = new RegExp(`^${desiredContextRoot}`)
    const _parsedUrl = Reflect.has(req, '_parsedUrl') ? req._parsedUrl : null
    const url = _parsedUrl !== null ? _parsedUrl : parseurl(req)
    const startsWithDesired = desiredContextRootRegExp.test(url.pathname)
    const isNotProperContextRoot = desiredContextRoot !== url.pathname
    if (isNotProperContextRoot && startsWithDesired === false) {
      const pathname = url.pathname === null ? '' : url.pathname
      const search = url.search === null ? '' : url.search
      const Location = desiredContextRoot + pathname + search
      res.writeHead(302, {
        Location
      res.end()
    next()
然后，每当开发中的同事到达开发 Web 开发服务/时，发生了意外情况，Nuxt 将自动重定向到/portal
