利用CloudFlare白嫖短网址网站!

首先需要去CloudFlare创建一个账号并登录!

然后点击 Workers ,如下图。

然后选择创建 Worker

然后在左侧脚本处,粘贴以下代码:

const html404 = `<!DOCTYPE html>
<body>
  <h1>404 Not Found.</h1>
  <p>The url you visit is not found.</p>
</body>`


async function randomString(len) {
  len = len || 6;
  let $chars = 'ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678';    /****默认去掉了容易混淆的字符oOLl,9gq,Vv,Uu,I1****/
  let maxPos = $chars.length;
  let result = '';
  for (i = 0; i < len; i++) {
    result += $chars.charAt(Math.floor(Math.random() * maxPos));
  }
  return result;
}
async function checkURL(URL){
    let str=URL;
    let Expression=/http(s)?:\/\/([\w-]+\.)+[\w-]+(\/[\w- .\/?%&=]*)?/;
    let objExp=new RegExp(Expression);
    if(objExp.test(str)==true){
      if (str[0] == 'h')
        return true;
      else
        return false;
    }else{
        return false;
    }
} 
async function save_url(URL){
    let random_key=await randomString()
    let is_exist=await LINKS.get(random_key)
    console.log(is_exist)
    if (is_exist == null)
        return await LINKS.put(random_key, URL),random_key
    else
        save_url(URL)
}
async function handleRequest(request) {
  console.log(request)
  if (request.method === "POST") {
    let req=await request.json()
    console.log(req["url"])
    if(!await checkURL(req["url"])){
    return new Response(`{"status":500,"key":": Error: Url illegal."}`, {
      headers: {
      "content-type": "text/html;charset=UTF-8",
      "Access-Control-Allow-Origin":"*",
      "Access-Control-Allow-Methods": "POST",
      },
    })}
    let stat,random_key=await save_url(req["url"])
    console.log(stat)
    if (typeof(stat) == "undefined"){
      return new Response(`{"status":200,"key":"/`+random_key+`"}`, {
      headers: {
      "content-type": "text/html;charset=UTF-8",
      "Access-Control-Allow-Origin":"*",
      "Access-Control-Allow-Methods": "POST",
      },
    })
    }else{
      return new Response(`{"status":200,"key":": Error:Reach the KV write limitation."}`, {
      headers: {
      "content-type": "text/html;charset=UTF-8",
      "Access-Control-Allow-Origin":"*",
      "Access-Control-Allow-Methods": "POST",
      },
    })}
  }else if(request.method === "OPTIONS"){  
      return new Response(``, {
      headers: {
      "content-type": "text/html;charset=UTF-8",
      "Access-Control-Allow-Origin":"*",
      "Access-Control-Allow-Methods": "POST",
      },
    })

  }

  const requestURL = new URL(request.url)
  const path = requestURL.pathname.split("/")[1]
  console.log(path)
  if(!path){

    const html= await fetch("https://cdn.jsdelivr.net/gh/xyTom/[email protected]/index.html")
    
    return new Response(await html.text(), {
    headers: {
      "content-type": "text/html;charset=UTF-8",
    },
  })
  }
  const value = await LINKS.get(path)
  console.log(value)
  

  const location = value
  if (location) {
    return Response.redirect(location, 302)
    
  }
  // If request not in kv, return 404
  return new Response(html404, {
    headers: {
      "content-type": "text/html;charset=UTF-8",
    },
    status: 404
  })
}



addEventListener("fetch", async event => {
  event.respondWith(handleRequest(event.request))
})

然后保存并部署。

接下来,去Workers KV中创建一个命名空间。Name处填写 link

然后去Worker的Settings选选项卡中绑定KV Namespace

其中Variable name填写LINKS, KV namespace填写你刚刚创建的命名空间。

然后你可以自行添加Route来实现域名绑定,如果有不会的可以留言咨询。

    好像还是引入了一个github上的页面,感觉可以自己修改成自己的。
