如果是之前博客的老读者，那么相信对Deno Deploy不太陌生。之前的教程我利用Deno Deploy，给大家做了反代网站的教程。但是有些小伙伴是想使用反代来代理WebSocket节点的。不过，我们得感谢zizifn这位作者，让我们在Deno Deploy反代WebSocket节点变成了可能。在这篇教程中，我来和大家讲解一下如何使用Deno Deploy反代Websocket节点
准备材料
部署步骤
- 打开Deno Deploy的官网：https://deno.com/deploy ，点击“Sign up”进行注册。如有账号点击“Sign in”登录
- 点击“New Project”按钮，创建一个项目
- 点击“Play”按钮，创建一个新的项目
- 将代码修改为下面的内容，然后点击“Save and deploy”按钮（将
xx.xxx.xxxx 替换成实际的节点地址）
