Cloudflare的东西，出了名的慷慨，Workers功能在前不久提供了免费的模式

每天10W次请求数量，无限流量，真猛啊！

拿去做个小站简直不要太舒服哦

Cloudflare的东西都懂的，抗DDoS一级棒哦，就是电信联通延迟有点美丽。。。

老规矩，先把代码丢上来，然后慢慢讲解

进入Cloudflare Workers控制台，有一个创建Worker的按钮。

还看？直接点进去啊，慌什么。。。

系统默认生成会自带一端Hello Word，我们将刚刚的代码替换进去

直接保存部署，当然，你也可以调整一下，在旁边的浏览里面查看页面效果

不出意料，非常无脑，直接就搞定了，自动生成的域名非常难受，你可以选择重命名来调整主机名….

…….

边缘脚本部署是不是很简单，还堪称0成本

什么是无服务器？

通常而言，构建和维护易于扩展的应用程序可支持需求高峰或全球用户群，但这需要大量前期工程和持续运营支持。 开发人员不得不花费大量时间编写支持代码，而非构建应用程序本身。 而借助 Cloudflare Workers，开发人员能够构建无服务器的可扩展应用程序，无需在基础设施或操作上花费时间和精力。

借助 Cloudflare Workers，开发人员能够在 Cloudflare 的全球云网络上部署无服务器的 JavaScript 应用程序，应用程序能够在这个网络中无缝扩展，更加接近最终用户。 Workers 基于 Service Workers API 构建，可为向应用程序发出的每次 HTTP(S) 请求接收事件。 然后，Workers 运行应用程序逻辑，并可向 Cloudflare Cache、Cloudflare Workers KV 或应用程序原始服务器发出后续请求，以将数据返回给用户。
