Cloudflare Worker+Vless，搭建零成本科学梯子
诺多发表于 2023-12-13 10:41:26
这个话题笔者就不展开说了，就是搭一个稳定可靠的梯子，但是不需要买VPS，除了需要一个域名以外，基本上属于零成本了，懂得都懂。
1️⃣ 前提条件
只有2个非常简单的条件，没什么难度。
- 有一个Cloudflare账号，免费计划就行
- 有一个域名，并且将DNS解析转到Cloudflare中
2️⃣ 搭建步骤
搭建这个服务是使用了Cloudflare的Worker和Pages服务每天可以有10万个免费请求次数这个福利，对于个人使用来说完全不用担心。所以为了你个人安全和不超次数，请不要分享给别人使用！请不要分享给别人使用！请不要分享给别人使用！
开始前请先完成上述前提条件，笔者就不赘述了，完全没难度。
1、打开Workers和Pages
登录Cloudflare之后，直接点击菜单Workers和Pages，进入到概述页面
2、创建Worker
点击创建应用程序按钮，进入创建页面，切换到Workers页签，接着点击页面中的创建Worker按钮，进入创建页面。
在创建页面中填写名称，比如就叫vless-worker，代码先保持默认不用管，然后点击部署按钮，完成创建。
3、编写Worker
重点来了。
首先回到概述页面，可以看到我们已经创建好的 Worker，直接点击名称进入 Worker 的主页。
接着点击右上角的快速编辑按钮，进入编辑页面，将Vless代码粘贴到编辑框中，然后点击右上角的保存并部署按钮，完成！代码比较长，放到文末了。
⚠️注意：代码中的第7行
userID，其实就是UUID，默认的值已经被广泛使用了，请一定要修改一下，如果你不知道如何生成UUID，可以到这个网站生成一个：https://it.huluohu.com/uuid-generator。
4、配置自定义域名
以上其实就已经完成了Vless的搭建，但是由于 Cloudflare 自带的Worker域名在国内属于不受欢迎的（你懂的），所以你的域名现在开始出场了，我们需要给这个 Worker 设置一个自定义域名。
首先还是回到到上面创建的 Worker 详情页面，点击触发器页签。继续点击添加自定义域按钮，开始添加一个自定义域名。
输入你的域名，例如tiz.yourdomain.com，并点击添加自定义域按钮，完成添加。请注意，输入的域名一定是已经将 DNS 解析添加到 Cloudflare 中的才可以。
至此，Cloudflare中的Worker都已经完成部署和设置了，下面就是如何使用这个Vless服务了。
3️⃣ 配置客户端
支持Vless协议的客户端很多，不同平台也都不大一样，这里笔者就不做任何推荐了，毕竟这玩意也是不受欢迎的。保险起见，笔者截了个图，请参考填写。
填写说明：
- 选择协议：选
vless - address：填前面设置的自定义域名
- 端口：支持6个https端口可任意选择(443、8443、2053、2083、2087、2096)
- id：就是代码中的 userID，千万不要泄露给其他人
- 选择网络：选
ws - host：留空即可
- path：填
/?ed=2048 - security：选
tls - tls servername：同样填前面设置的自定义域名
4️⃣ Vless代码
下面就是Vless代码，请直接复制即可，代码很长，可不要复制漏了。

注意：如果 ${hostName} 在本地网络打不开（中国移动用户注意）
客户端选项的伪装域名(host)必须改为你在CF解析完成的自定义域名
---------------------------------------------------------------
客户端必要文明参数如下：
客户端地址(address)：自定义的域名 或者 优选域名 或者 优选IP（反代IP必须与反代端口对应）
端口(port)：6个https端口可任意选择(443、8443、2053、2083、2087、2096)
用户ID(uuid)：${userID}
传输协议(network)：ws 或者 websocket
伪装域名(host)：${hostName}
路径(path)：/?ed=2048
传输安全(TLS)：开启
跳过证书验证(allowlnsecure)：false

客户端必要文明参数如下：

查看CF-workers-vless+ws+tls节点配置信息，请在浏览器地址栏输入：你设置的自定义域名/你设置的UUID
防止小白过多的操作失误，必须设置自定义域名后才能使用Workers方式的TLS模式，否则，建议只使用vless+ws节点即可
提示：使用pages方式部署，联通、电信用户大概率可以直接使用TLS模式，无需设置自定义域名
pages方式部署可参考此视频教程：https://youtu.be/McdRoLZeTqg
