1. 第一种方法：定时刷新token

import { calcDate } from '@/util/date.js'
import { getStore } from '@/util/store.js'

created() {
   //实时检测刷新token
   this.refreshToken()
 },
 
 methods: {
	// 方法
	refreshToken() {
	     this.refreshTime = setInterval(() => {
	       const token = getStore({
	         name: 'token',
	         debug: true
	       })
	       const date = calcDate(token.datetime, new Date().getTime())
	       if (validatenull(date)) return
	       if (300 < date.seconds && date.seconds < 600 && !this.refreshLock) {
	         this.refreshLock = true
	         this.$store
	           .dispatch('RefeshToken')
	           .then(() => {
	             this.refreshLock = false
	           })
	           .catch(() => {
	             this.refreshLock = false
	           })
	       }
	     }, 10000)
	   }
  }

2. 第二种方法：每次请求响应中去刷新token

import { calcDate } from '@/util/date.js'
import { getStore } from '@/util/store.js'
// 用于判断是否刷新
window.isReresh = false
...
//HTTPresponse拦截
axios.interceptors.response.use(
  res => {
    if (store.getters.token) {
      const token = getStore({
        name: 'token',
        debug: true
      })
      const date = calcDate(token.datetime, new Date().getTime())
      if (date.seconds < 600 && !window.isReresh) {// 小于10分钟则刷新token
        window.isReresh = true
        store
          .dispatch('RefeshToken')
          .then(() => {
            window.isReresh = false
          })
          .catch(() => {
            window.isReresh = false
          })
      }
    }
    return res
  },

  error => {
    // 请求超时处理
    if (error.message) {
      if (error.message.indexOf('timeout') !== -1) {
        Message({
          message: '请求超时，请重新刷新页面！',
          type: 'error'
        })
      }
    }

    if (axios.isCancel(error)) {
      console.log('repeated request: ' + error.message)
    }
    return Promise.reject(new Error(error))
  }
)
...
