如何从nuxt路由器模块的路由器.js文件?

您可以通过根上下文访问存储,Nuxt在 window.$nuxt 外部Vue组件:

// router.js
import Router from 'vue-router'

export function createRouter(ssrContext, createDefaultRouter, routerOptions) {
  const options = routerOptions ? routerOptions : createDefaultRouter(ssrContext).options

  const router = new Router({
    ...options
  })

  if (process.client) {
    router.beforeEach((to, from, next) => {
      // Since `beforeEach` is invoked before `window.$nuxt` is
      // initialized, use `setTimeout` without a timeout to wait
      // until the next macro tick.
      setTimeout(() => {
        window.$nuxt.$store.dispatch('myAction')
      })

      next()
    })
  }

  return router
}

如果唯一的理由是 @nuxtjs/router 模块将添加一个 beforeEach 路由器钩子,你可以用 Nuxt plugin

// plugins/router.js
export default ({ app, store }) => {
  app.router.beforeEach((to, from, next) => {
    store.dispatch('myAction')
    next()
  })
}

// nuxt.config.js
export default {
  plugins: [
    '~plugins/router.js'
  ]
}
