Vue3解析markdown并实现代码高亮显示的详细步骤

npm install marked -save    // marked 用于将markdown转换成html
npm install highlight.js -save   //用于代码高亮显示

import hljs from 'highlight.js';
import 'highlight.js/styles/atom-one-dark.css' //样式

//创建v-highlight全局指令
Vue.directive('highlight',function (el) {
  let blocks = el.querySelectorAll('pre code');
  blocks.forEach((block)=>{
    hljs.highlightBlock(block)
  })
})

 <!-- 正文输出 -->
<div class="entry-content">
  <div v-highlight v-html="article"  id="content"></div>
</div>

<script>
    // 将marked 引入
  import { marked }from 'marked';
    export default {
        name: 'articles',
        data(){
          return{
              article:''
          }
        },
        methods: {
          getPostDetail() {
            console.log('getPostDetail()'+this.id)
            fetchPostDetail(this.id).then(res => {
               this.postdetail=res.data
               // 调用marked()方法，将markdown转换成html
               this.article= marked(this.postdetail.content);
               console.log(res.data)
              }).catch(err => {
                  console.log(err)
              })

          },
        created() {
          //调用获取文章内容的接口方法
          this.getPostDetail()
        },
    }
 </script>
