Vue2 SSR渲染根据不同页面修改 meta

yarn add vue-meta

npm install vue-meta --save

import Vue from 'vue'
import Router from 'vue-router'
import Meta from 'vue-meta'
 
Vue.use(Router)
Vue.use(Meta)
 
export default new Router({
 // ...
})

import { app, router, store } from './app'
 
const isDev = process.env.NODE_ENV !== 'production'
const meta = app.$meta() // 这行
 
export default context => {
 router.push(context.url)
 context.meta = meta // 这行
 const ss = isDev && Date.now()
 // ...
}

renderStream.once('data', () => {
 res.write(indexHTML.head)
})

renderStream.once('data', () => {
 const { title, meta } = context.meta.inject()
 indexHTML.head = indexHTML.head.replace(/<title.?<\/title>/g, title.text())
 indexHTML.head = indexHTML.head.replace(/<meta.?name="description".?\/>/g, meta.text())
 res.write(indexHTML.head)
})

<title>xxxx</title>

<meta name="description" content="xxxx">

export default {
 name: 'frontend-index',
 prefetch: fetchInitialData,
 // 添加以下代码
 metaInfo () {
 const title = 'M.M.F 小屋 - 首页'
 return {
  title,
  meta: [{ vmid: 'description', name: 'description', content: title }]
