1.通过自定义指令去修改(单个修改比较好)

//1.在main.js 页面里添加自定义指令
Vue.directive('title', {//单个修改标题
  inserted: function (el, binding) {
    document.title = el.dataset.title
  }
})
//2.在需要修改的页面里添加v-title 指令
<div v-title data-title="我是新的标题"></div>.

2.使用插件 vue-wechat-title

//1.安装插件
npm vue-wechat-title --save
//2.在main.js里面引入插件
import VueWechatTitle from 'vue-wechat-title'//动态修改title
Vue.use(VueWechatTitle)
//3.在路由里面 添加title
         routes: [{
            path: '/login',
            component: Login,
            meta: {
                title: '登录'
            }
        }, {
            path: '/home',
            component: Home,
            meta: {
                title: '首页'
            }
        },]

//4.在app.vue 中添加 指令 v-wechat-title
<router-view v-wechat-title='$route.meta.title' />

3.通过 router.beforeEach 导航守卫来修改

//1.在router的index里写自己的路径和title
const router = new Router({
    routes: [
        {
            path: '/login',
            component: Login,
            meta: {
                title: '登录',
            },
        },
        {
            path: '/home',
            component: Home,
            meta: {
                title: '首页',
            },
        },
    ],
})
//2.使用router.beforeEach对路由进行遍历,设置title
router.beforeEach((to, from, next) => {
    //beforeEach是router的钩子函数,在进入路由前执行
    if (to.meta.title) {
        //判断是否有标题
        console.log(to.meta.title)
        document.title = to.meta.title
    } else {
        document.title = '默认title'
    }
    next()
})

4.使用 vue-mate 修改 title

https://github.com/declandewet/vue-meta 文档中比较详细地说明了在浏览器端和服务器端如何使用 vue-meta 修改页面头部信息
