（Nuxt.js / Vue.js）刷新后在Vuex存储中设置axios身份验证令牌会重置

我有以下商店代码来处理登录，注销，获取用户并将令牌设置为所有axios请求作为auth标头。

它与客户端渲染效果很好，比如说我进入登录页面，登录，获取令牌，将其存储在cookie中。。但是，当我刷新页面时，似乎不再设置令牌了。在NuxtServerInit上执行操作，仍然没有运气。任何有关我的代码失败的想法吗？

这是我的store / index.js文件：

import Cookie from 'cookie'
import Cookies from 'js-cookie'

export const state = () => ({
  sidebar: true,
  token: null,
  user: null
})

export const mutations = {
  // SET SIDEBAR
  toggleSidebar (state) {
    state.sidebar = !state.sidebar
  },
  // SET USER
  setUser (state, user) {
    state.user = user
  },
  // SET TOKEN
  setToken (state, token) {
    state.token = token
  }
}

export const getters = {
  loggedIn (state) {
    return Boolean(state.user && state.token)
  }
}

export const actions = {
  async nuxtServerInit ({ dispatch }, { req }) {
    await dispatch('fetch')
  },
  // Update token
  async updateToken ({ commit }, token) {
    // Update token in store's state
    commit('setToken', token)
    // Set Authorization token for all axios requests
    console.log('Setting axios token to: ', token)
    this.$axios.setToken(token, '')
    // Update cookies
    if (process.browser) {
      // ...Browser
      if (token) {
        Cookies.set('ccmsToken', token, { expires: 1 })
      } else {
        Cookies.remove('ccmsToken')
      }
    } else {
      // ...Server
      let params = {
        domain: '/'
      }
      if (!token) {
        let expires
        let date = new Date()
        expires = date.setDate(date.getDate() + 1)
        params.expires = new Date(expires)
      }
      this.app.context.res.setHeader('Set-Cookie', Cookie.serialize('ccmsToken', token, params))
    }
  },

  // Fetch Token
  async fetchToken ({ dispatch }) {
    let token
    // Try to extract token from cookies
    if (!token) {
      const cookieStr = process.browser ? document.cookie : this.app.context.req.headers.cookie
      const cookies = Cookie.parse(cookieStr || '') || {}
      token = cookies['ccmsToken']
    }
    if (token) {
      await dispatch('updateToken', token)
    }
  },

  // Reset
  async reset ({ dispatch, commit }) {
    commit('setUser', null)
    await dispatch('updateToken', null)
  },

  // Fetch
  async fetch ({ getters, state, commit, dispatch }, username = 'admin', { endpoint = 'http://localhost:8000/api/user' } = {}) {
    // Fetch and update latest token
    await dispatch('fetchToken')
    // Skip if there is no token set
    if (!state.token) {
      return
    }

    // Try to get user profile
    try {
      const data = await this.$axios.$get(endpoint + '?username=' + username)
      commit('setUser', data)
    } catch (e) {
      // Reset store
      await dispatch('reset')
    }
  },

  // Login
  async login ({ dispatch }, { fields, endpoint = 'http://localhost:8000/api/login' } = {}) {
    try {
      // Send credentials to API
      let data = await this.$axios.$post(endpoint, fields)
      if (data.success) {
        await dispatch('updateToken', data['token'])
        // Fetch authenticated user
        await dispatch('fetch', data.user.username)
      } else {
        throw new Error(data.message)
      }
    } catch (error) {
      if (error.response && error.response.status === 401) {
        throw new Error('Bad credentials')
      }
      throw error
    }
  },

  // Logout
  async logout ({ dispatch, state }) {
    try {
      await dispatch('reset')
    } catch (e) {
      console.error('Error while logging out', e)
    }
  }
