首先感谢 Cloudflare 公司为我们有限免费提供免费服务。

今天为大家带来一个无需购买 vps，无需花一分钱即可使用免费 vless 节点，速度非常快。重点还支持全球落地。

准备工作： 购买一个域名，免费域名也可以，要求有解析权限 注册一个 Cloudflare 账号，网址：https://www.cloudflare.com 开通 cloudflare worker 服务。 创建 worker 图片[1]-Cloudflare Worker 无需购买 VPS 搭建 VLESS 节点服务（支持全球落地）-何先生

这里名称随便写，然后点部署。

首先感谢原作者：https://github.com/zizifn/edgetunnel，作者已删库，请大家去给他点个 star。

下面代码是网上流传的一位不知名热心网友修改的可以访问 cf 网站的代码。

找到const userID = env.UUID || "b1f60b1d-a556-4372-8050-f78673d11ea0";这一行，将“b1f60b1d-a556-4372-8050-f78673d11ea0”这段 uuid 修改为你的，网上搜索 uuid 生成，有很多网站可以生成。

部署后返回 worker 页面，你会看到类似这样的网址：vless.你的用户名.workers.dev

但是这个网址有些地方被运营商给屏蔽了，你是使用不了的，这使用我们就需要用到域名了。

我们需要把域名接入 cloudflare，然后在 worker 页面添加一个子域名：

80 端口和 443 端口分别设置方法。

接下来就需要使用优选 ip 来加速访问啦。何先生偶尔也会扫描一些中转 ip 放到网站，但是最近没空扫描，这里使用匿名大佬解析好的域名：

cdn.chigua.tk (CNAME 域名)cdn.anycast.eu.org (部分地区有污染)中转阿里云 80 443 的 ddns 服务继续启用理论应该还支持 tls 2053 2083 2087 2096 8443非 tls 2052 2082 2086 2095 8080 8880目前已经支持分域名解析，香港暂时不考虑东京 NRT（推荐联通使用）nrt.chigua.tknrt.anycast.eu.org新加坡 SIN（推荐电信、移动使用）sin.chigua.tksin.anycast.eu.org法兰克福 FRA（推荐联通、移动使用）fra.chigua.tkfra.anycast.eu.org

分享何先生搭建好的 Cloudflare worker vless 节点：采用何先生自己扫描的香港等超高速的中转 ip：

Cloudflare 官方限制免费账户每天十万次请求，如果无法使用了就是请求满了，等第二天就可以继续愉快了。
