seo + vue-meta-info + vuex

简单使用

1.cmd安装vuex，vue-meta-info

cnpm install vuex -save
cnpm install vue-meta-info --save

2.src下新建store文件夹，新增src/store/index.js文件

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
const store = new Vuex.Store({
  state:{
    metaInfo:{
      title:"西安机床工具展览会",
      keywords:"机床，展览会，西安，高端机床制造商",
      description:"XIMS2021中国（西安）机床工具展览会以“精准、智造、融合、创新”为主题，为观众呈现代表行业发展的前沿技术和最新发展成果，强调和突出“创新”；依托陕西省强大的制造业资源及科教资源优势，集品牌展示、技术交流、贸易合作、宣传推广、国际研讨于一体，为行业上下游用户搭建便捷、高效的交流平台，实现机床企业与用户的融合、主机厂商与部件厂商的融合、产学研用的融合及协同创新，是推动机床工具转型升级的一站式会展平台。"
    }
  },
  mutations:{
    setMetas(state,data){
      state.metaInfo=data;
    }
  }
})
export default store;

3.main.js引入

// 引入vue-meta-info
import MetaInfo from 'vue-meta-info'
Vue.use(MetaInfo)

/* eslint-disable no-new 引入vuex */
new Vue({
  el: '#app',
  store,
  router,
  render: h => h(App)
})

4.App.vue

<template>
  <div id="app">
    <component :is="layout">
      <router-view v-if="isRouterAlive"/>
    </component>
  </div>
</template>

<script>
export default {
  name: 'App',
  //seo优化keyword title description
  metaInfo() {
    return {
      meta: this.metaData,
      title: this.titles,
    };
  },
  provide(){
    return {
      reload: this.reload
    }
  },
  data(){
    return {
      default_layout: 'default',//设置layout
      isRouterAlive: true,
      metaData: [
        {
          name: "keywords",
          content: this.$store.state.metaInfo.keywords,
        },
        {
          name: "description",
          content: this.$store.state.metaInfo.description,
        },
      ],
      titles: this.$store.state.metaInfo.title,
    }
  },
  computed:{
    layout(){
      return (this.$route.meta.layout || this.default_layout) + '-layout'
    }
  },
  watch: {
    $route(to, from) {
      setTimeout(() => {
        this.metaData = [
          {
            name: "keywords",
            content: this.$store.state.metaInfo.keywords,
          },
          {
            name: "description",
            content: this.$store.state.metaInfo.description,
          },
        ];
        this.titles = this.$store.state.metaInfo.title + "-西安机床展览会";
      }, 500);
    },
  },
  methods: {
    //通过声明reload方法，控制router-view的显示或隐藏，从而控制页面的再次加载
    reload(){
      this.isRouterAlive = false;
      this.$nextTick(function () {
        this.isRouterAlive = true;
      })
    }
  }
}
</script>

<style>

</style>

5.页面中使用

//  获取新闻详情
        getNewsDetail(){
          let _this = this;
          this.$http.getPage("/cms/id", {id:this.id}).then((res) => {
            if(res.code == 1){
              this.newsInfo = res.data;
              document.title = res.data.title;
              let metaInfo={
                title:_this.newsInfo.title,
                keywords:_this.newsInfo.tags,
                description:_this.newsInfo.description,
              }
              this.$store.commit("setMetas",metaInfo);
            }
          });
        },
