    前言

       本实验将会为大家解析cloud flare的反向解析代理服务如何搭建,works如何创建等等。本文中教学创建的实例已在文章编写结束后释放,该项技术不可用于违法用途!违者自行承担后果!!

原理拓扑图

一、知识链条

1、Cloud flare简介

      Cloudflare 是一家全球性的云服务提供商,成立于2009年。它提供了一系列网络基础设施和安全性服务,帮助网站加速、保护、以及优化其在线内容。

Cloudflare 提供的主要服务包括:

1. CDN(内容分发网络):通过将内容分发到全球性的数据中心,加速网站加载速度,提高用户体验。
2. DDoS 攻击防护:保护网站免受分布式拒绝服务(DDoS)攻击,确保服务的可用性和稳定性。
3. WAF(网络应用防火墙):监控和过滤网站流量,阻止恶意攻击、SQL 注入和跨站脚本等网络攻击。
4. DNS(域名解析服务):提供快速、可靠的域名解析服务,帮助网站管理和优化其网络流量。
5. SSL/TLS 加密:提供免费的 SSL/TLS 加密证书,加密网站与访问者之间的通信,保护数据安全和隐私。
6. Workers:允许开发者在 Cloudflare 的边缘网络上运行自定义的代码,以实现更高级的功能和定制化的处理。

Cloudflare 的服务被广泛应用于各种规模的网站和在线应用程序中,包括企业网站、电子商务平台、博客、游戏、移动应用等。其目标是通过提供简单易用、高性能和高安全性的服务,帮助客户在互联网上取得成功。同时,Cloud flare持有全球顶级DNS1.1.1.1,可见其实力不凡。

=========================================================================

2、VLess协议

       vless 协议是一个相对于 V2Ray 的一种新的协议,它是 V2Ray 的一个轻量级替代品。vless 的设计目标是减少传输数据的开销,提高性能,并且简化配置。

vless 协议的原理基本上与 V2Ray 中的 vmess 协议类似,都是在传输层上实现的一个加密隧道,用于在客户端和服务器之间传输数据。但是 vless 相对于 vmess 有一些不同之处:

1. **减少传输数据的开销**:vless 协议在传输数据时采用了更加精简的数据格式,以减少传输数据的开销,提高传输效率。
   
2. **简化配置**:相对于 vmess,vless 的配置更加简单,主要是因为它省略了一些在某些情况下不必要的选项和字段。

3. **增强安全性**:vless 在安全性方面与 vmess 相当,都是采用了 TLS 加密和传输,保障了数据的安全性和隐私。

4. **性能提升**:由于 vless 减少了数据传输的开销,并且在设计上更加精简,因此在一些场景下可能会提供更好的性能表现。

总的来说,vless 协议是为了简化配置、提高性能、减少传输开销而设计的一种协议,它保留了 vmess 协议的安全性和灵活性,同时简化了配置和提高了性能。

3、Cloud flare-works实例

        Cloudflare的"Works"是Cloudflare推出的一系列整合服务,旨在为企业提供更全面的网络安全和性能优化解决方案。Works整合了Cloudflare的不同产品,包括:

1. **Access:** 提供零信任访问控制,确保用户可以安全地访问企业网络和应用程序,无论他们身在何处。

2. **Gateway:** 提供安全的互联网访问,包括网络内容过滤、恶意软件防护、广告拦截和隐私保护。

3. **Spectrum:** 扩展Cloudflare的边缘网络保护到任何TCP/UDP流量,使得所有的网络流量都能受到Cloudflare的保护。

4. **Workers:** 允许开发者在Cloudflare的边缘网络上运行轻量级的JavaScript代码,从而实现定制化的网络功能和逻辑。

5. **Orbit:** 提供实时的API和事件监控,使得开发者可以实时地查看和分析其应用程序的性能和行为。

通过将这些服务整合在一起,Cloudflare Works可以为企业提供更强大、更全面的网络安全和性能优化解决方案,帮助他们保护应用程序、数据和用户,并提高网络性能和可用性。

4、UUID

      UUID(Universally Unique Identifier)是一种标识符,用于在计算系统中唯一地标识信息或实体。它是由一个128位的数字组成,通常以32个十六进制数字的形式表示,中间用连字符分隔。UUID的生成算法保证了在理论上具有非常低的重复概率。

UUID广泛应用于各种场景,例如:

1. 数据库系统:UUID可以用作数据库表格的主键,确保每个记录在整个数据库中具有唯一标识。
2. 分布式系统:在分布式系统中,UUID可以用于唯一标识各个节点、任务或事件,以确保全局唯一性。
3. 软件开发:开发人员可以使用UUID作为临时文件名、会话标识符或唯一的标识符来跟踪和管理数据。
4. 网络通信:UUID可以用于标识网络协议中的消息、数据包或会话,以确保唯一性和识别性。

总之,UUID是一种在计算系统中用于唯一标识信息或实体的标识符,具有广泛的应用领域。

接下来我们开始创建workers实例

二、创建workers

1、访问cloud flare

       先进入官网>>>Cloud flare<<<

       请记住,访问cloud flare时,会有人机验证,照常过就行,如果无法通过,请开启霍格沃兹力量或者切换IP即可。

这里已经进入首页,可以在右上角调整语言设置:

首先,你要有非CN的账号,(推荐使用Google)我这里使用Google/US账户进行注册登录:

进入cloud flare首页,在左侧找到workers和pages,进入。

2、创建workers

进入创建应用程序,开始创建一个workers实例。

给你的workers创建一个名称,我这里就使用ceshi,然后点击部署。

部署完成后,点击编辑代码。

将默认原来的代码全部清除

3、实例代码部署

edgetunnel/src/worker-vless.js at main · leilei223/edgetunnel · GitHub

---------------------------------------------------------------------------------------------------------------------------------

     导入完成后,我们需要修改两个地方,分别是UUID和CDN-IP。CDN-IP必须是反代IP,不能是官方IP!!!

4、UUID生成

    UUID的大概解释在本文开头的知识链条中有比较标准的解释,大家可以作为参考。UUID因其属性,随机生成且基本不会重合,我们现在去生成它,将它放入代码中即可。这里给大家推荐一个UUID在线随机生成的网站,希望能帮到各位开发者和极客玩家>>>open<<<,网址:

https://1024tools.com/uuid

进入后点击生成即可,然后随便选择一个就行,UUID非常重要,请把你使用的UUID保存一份副本,避免后续的操作无法进行!!!

这里我则第二个,复制出来后回到实例代码中,修改UUID为生成的这个。

5、cloud flare-proxy-IP 、proxy域的选择

优质域名推荐

cdn-all.xn--b6gac.eu.org
cdn.xn--b6gac.eu.org
cdn-b100.xn--b6gac.eu.org
edgetunnel.anycast.eu.org
cdn.anycast.eu.org(亚洲地区)
jp.cloudflarest.link
achk.cloudflarest.link(阿里香港优选)

这里给大家两种优选cloud flare优质IP的方案:

2、个人推荐

113.64.186.198 
103.200.112.108
199.15.76.35

edgetunnel.anycast.eu.org(美国的加速CDN)
cdn.anycast.eu.org(香港日本新加坡加速CDN)

香港优选IP:20.187.89.16
日本高速优选IP:146.56.149.205
美国优选IP:172.64.135.146)
韩国高速优选IP:129.154.199.251
日本高速优选IP:146.56.149.205

cdn-all.xn--b6gac.eu.org
cdn.xn--b6gac.eu.org 
cdn-b100.xn--b6gac.eu.org 
edgetunnel.anycast.eu.org 
cdn.anycast.eu.org 

    同时也可以选出运营商的最优反代IP,放入实例代码中的CDN-IP位置即可。这里我就直接使用这个IP。

113.64.186.198 

填入后点击部署即可。

我已经保存部署过了,所以这里这个按钮是灰色的

到这里,cloud flare的实例部署就已经完成了。

三、使用方法(无域名)

生成的实例流量转发的协议为vless,所以Vtwo(2)ray是个不错的选择.

1、V222222222222rayn

        复制刚刚创建的代码地址,格式为:https://vless.xxx.workers.dev/,其中 vless 为创建的脚本名称,xxx 为 CloudFlare 用户名。

复制出来后,后面加个/+UUID,如下

https://ceshi.xiaorantang68.workers.dev/37959939-2926-4e4c-a0d2-6468a1b9f7f7

这样我们就获取到了vless服务器的两个节点信息

     复制红框内的内容后粘贴进v222222222222rayn

    添加完成,但是现在这个服务器还不能使用,需要对节点进行进一步的修改。

因为不使用域名,所以加密方式不需要选择,将TLS改为空

如下图:

端口呢,也不能使用443端口,这里我切换为80端口(不使用TLS可以将端口改为80或2052)

2、修改地址

    现在就可以进行IP的优选了,脚本可以在我的仓库下载:https://github.com/Li468446/workers.js

   

填入v222222222rayn的vless服务器连接信息中即可。

lanzou:https://pan.lanpw.com/b0742hkxeicon-default.png?t=N7T8https://pan.lanpw.com/b0742hkxe

       下载下来后运行jp.bat批处理程序即可自动优选。优选前请关闭所有的系统代理,避免优选出现误差!!!

优选结果会写入rest.csv文件内,填入vless服务器IP中即可,这里就不多做解答

优选出来的IP直接填入vless服务器的地址栏即可,确定后切换为活动服务器,访问谷歌尝试:

到这里,v2222222222222rayn的配置就完成了,可以进行测试

四、实例测试

我这里优选出来的本地IP是104.19.170.**,填入后访问谷歌,测试成功。

查看cloud flare的实例,有正常的请求,正常工作。

实验成功

五、总结

       需要有一定的web基础和网络代理的基础,过程繁琐,在这个过程中,最容易出错的地方就在于实例中的workers的proxy IP和v222222222222rayn的客户端连接的CF优选IP容易搞混淆,Proxy-IP必须是反向代理IP,否则实例的反向代理会出现问题。
