Cloudflare服务工作者代码可“绕过Cookie上的缓存”不工作 [英] Cloudflare service worker code to "Bypass cache on cookie" not working

问题描述

我以Cloudflare Service Worker的身份编写了这段代码，目的是精确模拟其本机功能，以绕过cookie上的缓存。具体来说，如果某人拥有Wordpress Cookie，它将绕过缓存，否则不会。

它似乎根本不起作用-尽管有Cookie和正在登录（通过Chrome开发者工具确认）-在此示例域上，我仍然获得Cloudflare缓存HIT-

解决方案

尝试一下，让我知道

  addEventListener（'fetch' ，事件=> {
 let request = event.request 
 var flag = false; 
 if（request.headers.has（'Cookie'））{
 var cookie = request.headers.get（'Cookie'）; 
对= cookie.split（;）; 
 var patt = new RegExp（ wordpress_logged_in。* | wp_woocommerce_session。*）; 
 for（var i = 0; i  if（patt.test（pairs [i]））{
 flag = true; 
休息时间； 
} 
} 
 console.log（flag）; 
 if（request.headers.has（'Cookie'）&& flag）{
 let newHeaders = new Headers（request.headers）
 newHeaders.set（'Cache-Control' ，'no-cache'）
 newHeaders.set（'Pragma'，'no-cache'）
 event.respondWith（fetch（request，{headers：newHeaders}））
} 
 //使用默认行为。 
的回报； 
} 
}）
  

I wrote this code as a Cloudflare Service Worker which is meant to precisely emulate their native function for "Bypass cache on cookie". Specifically, if someone has a Wordpress cookie - it would bypass cache, otherwise it does not.

It does not seem to function at all - in that despite having a cookie and being logged in (confirmed via Chrome developer tools) - I still get a Cloudflare cache HIT on this example domain - Tallyfy. Anything wrong with it? Help appreciated!

// A Service Worker which skips cache if the request contains a cookie.
addEventListener('fetch', event => {
let request = event.request;

var flag=false;
if(request.headers.cookie)   {

var pairs = request.headers.cookie.split(";");
var patt = new RegExp("wp-.*|wordpress.*|comment_.*|woocommerce_.*")


for(var i=0;i<pairs.length;i++){
  if(patt.test(pairs[i])){
      flag = true;
      break;
  }
}

}

  if (request.headers.has('Cookie') && flag) {
    // Cookie present. Add Cache-Control: no-cache.
    let newHeaders = new Headers(request.headers)
    newHeaders.set('Cache-Control', 'no-cache')
    event.respondWith(fetch(request, {headers: newHeaders}))
  }
  // Use default behavior.
  return
})

解决方案

try this and let me know

addEventListener('fetch', event => {
  let request = event.request
  var flag = false;
  if (request.headers.has('Cookie')) {
    var cookie = request.headers.get('Cookie');
    pairs = cookie.split(";");
    var patt = new RegExp("wordpress_logged_in.*|wp_woocommerce_session.*");
    for(var i=0;i<pairs.length;i++){
      if(patt.test(pairs[i])){
          flag = true;
          break;
      }
    }
    console.log(flag);
    if (request.headers.has('Cookie') && flag) {
      let newHeaders = new Headers(request.headers)
      newHeaders.set('Cache-Control', 'no-cache')
      newHeaders.set('Pragma', 'no-cache')
      event.respondWith(fetch(request, {headers: newHeaders}))
    }
    // Use default behavior.
    return;
  }
})
