如何利用Cloudflare Workers构建一个免费无服务器导航页 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。。。》》》白嫖万岁！老规矩，先把代码丢上来，然后慢慢讲解const config = { title: "导航首页", //write your website title subtitle: "鹏龙-道记", //write your website subtitle logo_icon: "sitemap", //select your logo by semantic-ui icon (you can get more msg in:https://semantic-ui.com/elements/icon.html) hitokoto: true, //use hitokoto or not search:true, //enable search function search_engine:[ //choose search engine which you use { name:"百 度", template:"https://www.baidu.com/s?wd=$s" }, { name:"谷 歌", template:"https://www.google.com/search?q=$s" }, { name:"360", template:"https://www.so.com/s?q=$s" }, { name:"shodan", template:"https://www.shodan.io/search?query=$s" }, ], selling_ads: false, //Selling your domain or not.(turning on may be helpful for selling this domain by showing some ads.) sell_info:{ domain:"example.com", price:500, //domain price mon_unit:"yen sign", //monetary unit contact:[ //how to contact you { type:"envelope", //contact type ("weixin","qq","telegram plane","envelope" or "phone") content:"info@example.com" } ] }, lists: [ //Url list { name:"技术", icon:"code", list:[ { url:"https://oschina.net/", name:"开源中国", desc:"程序员集散地" }, { url:"https://v2ex.com", name:"V2EX", desc:"程序员集散地" }, { url:"https://csdn.net/", name:"CSDN技术社区", desc:"程序员集散地" }, { url:"https://github.com/", name:"Github", desc:"程序员集散地" }, { url:"https://www.vulbox.com/", name:"漏洞盒子", desc:"漏洞盒子" }, { url:"https://www.ichunqiu.com/", name:"I春秋", desc:"I春秋" }, { url:"https://www.butian.net/", name:"补天", desc:"补天" }, { url:"https://www.freebuf.com/", name:"freebuf", desc:"freebuf" }, ] }, { name:"学习", icon:"graduation cap", list:[ { url:"https://w3school.com.cn/", name:"W3school在线教程", desc:"程序员集散地" }, { url:"https://www.runoob.com/", name:"菜鸟教程", desc:"程序员集散地" }, { url:"https://segmentfault.com/", name:"思否社区", desc:"程序员集散地" }, { url:"https://jianshu.com/", name:"简书", desc:"程序员集散地" }, ] }, { name:"博客圈", icon:"code", list:[ { url:"https://www.jcdpn.cn/", name:"鹏龙-道记", desc:"日常更新" }, ] } ] } const el = (tag, attrs, content) => `<${tag} ${attrs.join(" ")}>${content}</${tag}>`; async function handleRequest(request) { const init = { headers: { 'content-type': 'text/html;charset=UTF-8', }, } return new Response(renderHTML(renderIndex(),config.selling_ads? renderSeller() :null), init); } addEventListener('fetch', event => { return event.respondWith(handleRequest(event.request)) }) /*通过分析链接 实时获取favicon * @url 需要分析的Url地址 */ function getFavicon(url){ if(url.match(/https{0,1}:\/\//)){ //return "https://ui-avatars.com/api/?bold=true&size=36&background=0D8ABC&color=fff&rounded=true&name=" + url.split('//')[1]; return "https://icon.occ.hk/get.php?url=" + url; }else{ //return "https://ui-avatars.com/api/?bold=true&size=36&background=0D8ABC&color=fff&rounded=true&name=" + url; return "https://icon.occ.hk/get.php?url=http://" + url; } } /** Render Functions * 渲染模块函数 */ function renderIndex(){ const footer = el('footer',[],el('div',['class="footer"'],'Powered by' + el('a',['class="ui label"','href="https://www.jcdpn.cn/"','target="_blank"'],el('i',['class="github icon"'],"") + '龙帝') + ' &copy;')); return renderHeader() + renderMain() + footer; } function renderHeader(){ const item = (template,name) => el('a',['class="item"',`data-url="${template}"`],name); var nav = el('div',['class="ui large secondary inverted menu"'],el('div',['class="item"'],el('p',['id="hitokoto"'],'条条大路通罗马'))) var title = el('h1',['class="ui inverted header"'],el('i',[`class="${config.logo_icon} icon"`],"") + el('div',['class="content"'],config.title + el('div',['class="sub header"'],config.subtitle))); var menu = el('div',['id="sengine"','class="ui bottom attached tabular inverted secondary menu"'],el('div',['class="header item"'],'&nbsp;') + config.search_engine.map((link,key) =>{ if(key == 0){ return el('a',['class="active item"',`data-url="${link.template}"`],link.name); }else{ return item(link.template,link.name); } }).join("")) var input = el('div',['class="ui left corner labeled right icon fluid large input"'],el('div',['class="ui left corner label"'],el('img',['id="search-fav"','class="left floated avatar ui image"','src="https://www.baidu.com/favicon.ico"'],"")) + el('input',['id="searchinput"','type="search"','placeholder="搜索你想要知道的……"','autocomplete="off"'],"") + el('i',['class="inverted circular search link icon"'],"")); return el('header',[],el('div',['id="head"','class="ui inverted vertical masthead center aligned segment"'],(config.hitokoto ? el('div',['id="nav"','class="ui container"'],nav) : "") + el('div',['id="title"','class="ui text container"'],title + (config.search ? input + menu :"") + `${config.selling_ads ?
