授人以鱼不如授人以渔 今天我要教大家的是利用CloudFlare 源码和原理皆来自于https://github.com/EtherDream/jsproxy/tree/master/cf-worker 因为目前国内各种工具数不胜数，质量参差不齐。使用这个方法可以从根本上解决隐私问题！而且操作简单！
第一步，登录注册CloudFlare账号 workers.cloudflare.com 注册过程在这里略过不做讲解！重要的是这个方法完全免费！ 注册好账号之后进入页面，也是点击左上角 CloudFlare标志
然后选择workers
再点击创建
选中左侧编辑栏所有内容，全部删除。
打开 raw.githubusercontent.com/EtherDream/… 复制页面里的所有内容！
复制到workers页面左侧编辑栏 然后点击保存
URL右侧的保存也点击一次。
复制这个url 到浏览器打开
也可以点击左上角回到首页 再点击右侧workers
就可以看到刚才创建的项目了。点击分享标志会自动打开！这时候你已经成功的可以出国了！
如图，你现在就已经靠自己的操作复制成功的上路了！
经过测试youtube看视频的速度有时候会很不理想。 所以还有一种方法可以让你寻找一些免费的节点 回到最开始的地方 打开谷歌搜索
把东西直接放进来，你们复制一下就OK
