vue单页面能做seo吗

if(process.browser){
 console.log(window);
}

if (process.browser) {
     var { WOW } = require('wowjs');
     require('wowjs/CSS/libs/animate.css');
 }

// 并发加载多个接口：
  async asyncData ({ app, query }) {
    let [resA, resB, resC] = await Promise.all([
      app.$axiOS.get('/api/a'),
      app.$axios.get('/api/b'),
      app.$axios.get('/api/c'),
     ])
     
     return {
       dataA: resA.data,
       dataB: resB.data,
       dataC: resC.data,
     }
  }

1.获取动态路由参数，如：

/list/:id' ==>  '/list/123

接收：

async asyncData ({ app, query }) {
  console.log(app.context.params.id) //123
}
2.获取url?获取参数，如：

/list?id=123

接收：

async asyncData ({ app, query }) {
  console.log(query.id) //123
}
