浅谈Vue SSR 的 Cookies 问题

namespaced: true,
state,
actions,
mutations,
getters
}

这里一定要注意, state 一定要用函数返回值来初始化 state, 不然会导致所有用户共用 state

步骤5:

在 api 里接收 cookies, 并加到 axios 的 headers 里

import axios from 'axios'
import qs from 'qs'
import config from './config-server'
const parseCookie = cookies => {
 let cookie = ''
 Object.keys(cookies).forEach(item => {
  cookie+= item + '=' + cookies[item] + '; '
 })
 return cookie
}
export default {
 get(url, data, cookies = {}) {
  const cookie = parseCookie(cookies)
  return axios({
   method: 'get',
   url: config.api + url,
   data: qs.stringify(data),
   timeout: config.timeout,
   headers: {
    'X-Requested-With': 'XMLHttpRequest',
    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
    cookie
   }
  })
 },
}

第四种方案

步骤1:

还是在 server.js 里, 把 cookies 注入到 context 中

const context = {
  title: 'M.M.F 小屋',
  url: req.url,
  cookies: req.cookies,
}
renderer.renderToString(context, (err, html) => {
  if (err) {
    return handleError(err)
  }
  res.end(html)
})

步骤2:

在entry-server.js里, 将cookies作为参数传给 api.setCookies 方法, api.setCookies 是什么东西后面会有

api.setCookies(context.cookies) // 这一句
Promise.all(matchedComponents.map(({asyncData}) => asyncData && asyncData({
 store,
 route: router.currentRoute,
 cookies: context.cookies,
 isServer: true,
 isClient: false
}))).then(() => {
 // ...
}

步骤3:

重写 api.js

import axios from 'axios'
import qs from 'qs'
import config from './config-server'
const parseCookie = cookies => {
  let cookie = ''
  Object.keys(cookies).forEach(item => {
    cookie+= item + '=' + cookies[item] + '; '
  })
  return cookie
}
export default {
  api: null,
  cookies: {},
  setCookies(value) {
    value = value || {}
    this.cookies = value
    this.api = axios.create({
      baseURL: config.api,
      headers: {
        'X-Requested-With': 'XMLHttpRequest',
        cookie: parseCookie(value)
      },
      timeout: config.timeout,
    })
  },
  post(url, data) {
    if (!this.api) this.setCookies()
    return this.api({
      method: 'post',
      url,
      data: qs.stringify(data),
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
