前两篇文章我们都是用V2rayN工具的实现节点的转发，这篇文章我们要用订阅链接的方式把我们部署的免费科学上网节点转发出来。
准备工作
-
我们要有一个Cloudflare账号，没有的小伙伴可以到Cloudflare官网上注册一个。不知道如何使用Cloudflare的小伙伴可以参考这篇文章。【如何使用cloudflare来进行域名解析】
-
我们需要在worker里部署一个免费的科学上网节点。【自己动手搭建一个永久免费的科学上网节点】【如何优选反代IP】
-
一个域名。【eu.org真正永久免费的域名】【教你申请pp.ua免费域名】
-
本篇文章所需的代码。下载地址
开始部署
首先，我们要创建一个worker项目，这里我就不多赘述了，相信看过前两篇文章的小伙伴这一步已经可以独立完成了。不过这次我们要用的代码和之前的不一样，代码如下：

代码粘贴之后记得修改UUID和服务器地址大概在104行 url.hostname = 'tesla.com'; 我喜欢用特斯拉。
然后，我们再配置一个域名。否则，没有其他科学上网环境的情况下是打不开链接的。
接下来，配置好域名后我们浏览器输入 https://你的域名/UUID 来获取我们的节点。
你可以直接把这两个节点复制到V2rayN里。但是，我们这次不这么做，换一种方式。右键 clash 节点订阅链接 复制链接。
打开 Clash Verge 软件，做一下必要的设置。设置好之后，再重新打开一次软件。
完事儿之后把订阅链接粘贴到这个软件里。
一切就绪之后，在设置里或者在右下角右键小图标打开系统代理，就可以科学上网了。
优选反代IP
完成以上步骤还不够，我们还要进行优选反代IP的操作。解压下载好的优选工具，双击 config.txt 配置文件，按照下面的格式填写。
api_key=CF解析域名的api-key
email=CF登录邮箱
zone_id=CF解析域名的区域ID
domain=CF解析的一级域名
subdomain=二级域名自定义名称
telegramBotToken=TG的token
telegramBotUserId=TG的用户ID
telegramapi=默认api.telegram.org官方api
token=Pushplus的token
cf_port=13个自定义端口（支持tls的6个端口：443、8443、2053、2083、2087、2096，支持非tls的7个端口：80、8080、8880、2052、2082、2086、2095）
cf_n=默认1000，测速线程数量最高值
cf_dn=默认10，测速并显示的IP数量
cf_sl=默认5，下载速度下限
cf_tl=默认250，平均延迟上限
cf_tll=默认30，平均延迟下限
cf_f=ip.txt代表优选反代IPV4，ipv4.txt代表优选官方IPV4，ipv6.txt代表优选官方IPV6，与cf_fdip必须同步
cf_cs=1代表测速，0代表不测速
cf_url=自定义测速地址，TLS的6个端口要用https://测速地址，非TLS的7个端口要用http://测速地址
cf_fdip=1代表优选反代，0代表优选官方，与cf_f必须同步
cf_cfup=1代表优选IP+dns解析+通知一条龙，0代表仅优选IP
cf_cfde=1代表删除指定二级域名称解析记录，0代表删除所有一级域解析记录
前三项是cloudflare的一些信息，进入域名查看
第6-8项是设置telegram机器人推送的一些信息，如果你没有留白就好。
第9项是设置微信推送，个人还是比较推荐的。点击这里用微信登录获取token。
要特别注意两点
第一， cf_port 如果你选择的是443系列的端口，那么 cf_url 你就要输入 https:// ，如果你选择的是80系列的端口，cf_url 你就要输入 http:// 。
第二， cf_f 你要是填入的是 ip.txt 那么 cf_fdip 你就要填入 1 ，如果你是 ipv4.txt 那么 cf_fdip 你就要填入 0 。
其余设置相对来说比较简单，不知道怎么设置的请参考，文件夹里的 使用前必看说明.txt 。
设置完之后，保存。然后再双击 一条龙优选IP.exe 文件运行脚本。完毕之后，会自动把优选之后的IP解析设置的二级域名里。
就像这样
重新运行之后，脚本会自动删除上一次解析的域名，然后再重新写入最新优选的IP，并指向我们设置的二级域名。
修改worker代码
打开我们部署的worker项目编辑代码，将我们配置的二级域名填入到这里，我这里是第10行，你们你们仔细看看，找不到就用 Ctrl+F 搜索 const proxyIPs 这个字段。修改完之后，再点击 保存并部署 。
最后，到Clash Verge里把订阅链接更新一下就好了。
OK，文章最后还是要做一下提醒，科学上网一时爽，一直用一直爽。
