前言
最近几天国内360旗下推出了一款叫做tuber浏览器的app，号称可以合法免费翻墙！就在短短的一天内，下载量就超过了550万次，火爆了全网，在YouTube或Google里铺天盖地的都是有关tuber浏览器的新闻，各种评测各种猜测也随之而来！但不知是由于下载量过大的原因还是处于种种压力，这款浏览器在一天之内就挂掉了，甚至官网都不能打开了！按说得到国家认可的app不应该因为服务器过载而挂掉才是啊？那么至于其他原因，咱们这里就不再去深做研究！但话又说回来，这款浏览器就算至今可用，那么它那需要手机号实名注册的政策，你的一切上网行为都将被监视着，你还敢用吗？我是不敢，倒不是怕啥，就是不喜欢被监视，有种被XX的感觉！
但只可惜，这款浏览器只是昙花一现，没有泛起任何大的波澜，就匆匆离世！毕竟只是想看看YouTube视频和google资料，且又不关心政治新闻的人占绝大多数，这样就对很大一部分人来说是比较惋惜的，不过呢？咱们也不用气馁！tuber浏览器能再带节点免费翻墙上网，那么我们为什么不能自己搭建一个类似的网页呢？重要的是，我们也是要无任何损失的，去做一个完全免费又真正属于自己的免费翻墙站点！不仅可以自己用，还可以分享给身边的朋友，让他们也能一睹外网的风采！
那如何实现呢？我们就需要借助于cloudflare来实现此功能！大家都知道，cloudflare自从推出了CloudFlare Workers这个项目，被众多程序员推崇！利用Workers部署jsproxy进行反代！！！将自己的代码复制进去就可实现我们想要的效果！而这个项目最终效果是让我们接入到特定服务器来进行科学上网！方便广大学子外网查资料所用！最终效果和tuber浏览器也是非常像！
站点预览准备工作：
1、要拥有一个cloudflare的账号；点击进入账号申请
2、一个域名地址并解析到cloudflare上去托管；freenom域名免费申请：点击进入
3、并激活workers功能！
第一步现在域名解析
第二步进入workers部署代码
点击创建一个workers后进入部署源码：
