实现思路:
1、因为GPT请求返回来得数据是markdown数据,主要是用marked解析markdown数据格式
marked.parse(message);
2、然后用highlight实现代码的高亮显示
https://www.jsdelivr.com/
最开始这里不晓得怎么引入, 然后用
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/highlight.js/styles/default.min.css">
<script src="https://cdn.jsdelivr.net/npm/highlight.js"></script>
提示没有require
