CookieCloud

CookieCloud是一个和自架服务器同步Cookie的小工具，可以将浏览器的Cookie及Local storage同步到手机和云端，它内置端对端加密，可设定同步时间间隔。

最新版本支持了对同域名下local storage的同步

⚠️ Breaking Change

由于支持 local storage 的呼声很高，因此插件版本 0.1.5+ 除了 cookie 也支持了 local storage，这导致加密文本格式变化（从独立cookie对象变成{ cookie_data, local_storage_data }）。

另外，为避免配置同步导致的上下行冲突，配置存储从 remote 改到了 local，使用之前版本的同学需要重新配置一下。

对此带来的不便深表歉意 🙇🏻‍♂️

FAQ

目前只支持单向同步，即一个浏览器上传，一个浏览器下载
浏览器扩展只官方支持 Chrome 和 Edge。其他 Chrome 内核浏览器可用，但未经测试。使用源码 cd extension && pnpm build --target=firefox-mv2 可自行编译 Firefox 版本，注意 Firefox 的 Cookie 格式和 Chrome 系有差异，不能混用

服务器端

第三方

由第三方提供的免费服务器端，可供试用，稳定性由第三方决定。感谢他们的分享 👏

由于部分服务器端版本较久，如测试提示失败可添加域名关键词再试

自行架设

方案一：通过Docker部署，简单、推荐方案

支持架构：linux/amd64,linux/arm/v7,linux/arm64/v8,linux/ppc64le,linux/s390x

用 Docker 命令启动

docker run -p=8088:8088 easychen/cookiecloud:latest

默认端口 8088 ，镜像地址 easychen/cookiecloud

指定API目录·可选步骤可跳过

添加环境变量 -e API_ROOT=/二级目录需要以斜杠开头 可以指定二级目录:

docker run -e API_ROOT=/cookie -p=8088:8088 easychen/cookiecloud:latest

用 Docker-compose 启动

version: '2'
services:
  cookiecloud:
    image: easychen/cookiecloud:latest
    container_name: cookiecloud-app
    restart: always
    volumes:
      - ./data:/data/api/data
    ports:
      - 8088:8088

docker-compose.yml由aitixiong提供

方案二：通过 Node 部署

适用于没有 docker 但支持 node 的环境，需要自行先安装 node

cd api && yarn install && node app.js

默认端口 8088 ，同样也支持 API_ROOT 环境变量

API 接口

上传：

method: POST
url: /update
参数
- uuid
- encrypted: 本地加密后的字符串

下载：

method: POST/GET
url: /get/:uuid
参数：
- password:可选，不提供返回加密后的字符串，提供则发送尝试解密后的内容；

Cookie加解密算法

加密

const data = JSON.stringify(cookies);

md5(uuid+password) 取前16位作为key
AES.encrypt(data, the_key)

解密

md5(uuid+password) 取前16位作为key
AES.decrypt(encrypted, the_key)

解密后得到 data ，JSON.parse(data) 得到数据对象{ cookie_data, local_storage_data };

参考函数

function cookie_decrypt( uuid, encrypted, password )
{
    const CryptoJS = require('crypto-js');
    const the_key = CryptoJS.MD5(uuid+'-'+password).toString().substring(0,16);
    const decrypted = CryptoJS.AES.decrypt(encrypted, the_key).toString(CryptoJS.enc.Utf8);
    const parsed = JSON.parse(decrypted);
    return parsed;
}

无头浏览器使用CookieCloud示例

请参考 examples/playwright/tests/example.spec.js

test('使用CookieCloud访问nexusphp', async ({ page, browser }) => {
  // 读取云端cookie并解密
  const cookies = await cloud_cookie(COOKIE_CLOUD_HOST, COOKIE_CLOUD_UUID, COOKIE_CLOUD_PASSWORD);
  // 添加cookie到浏览器上下文
  const context = await browser.newContext();
  await context.addCookies(cookies);
  page = await context.newPage();
  // 这之后已经带着Cookie了，按正常流程访问
  await page.goto('https://demo.nexusphp.org/index.php');
  await expect(page.getByRole('link', { name: 'magik' })).toHaveText("magik");
  await context.close();
});

函数

async function cloud_cookie( host, uuid, password )
{
  const fetch = require('cross-fetch');
  const url = host+'/get/'+uuid;
  const ret = await fetch(url);
  const json = await ret.json();
  let cookies = [];
  if( json && json.encrypted )
  {
    const {cookie_data, local_storage_data} = cookie_decrypt(uuid, json.encrypted, password);
    for( const key in cookie_data )
    {
      // merge cookie_data[key] to cookies
      cookies = cookies.concat(cookie_data[key].map( item => {
        if( item.sameSite == 'unspecified' ) item.sameSite = 'Lax';
        return item;
      } ));
    }
  }
  return cookies;
}

function cookie_decrypt( uuid, encrypted, password )
{
    const CryptoJS = require('crypto-js');
    const the_key = CryptoJS.MD5(uuid+'-'+password).toString().substring(0,16);
    const decrypted = CryptoJS.AES.decrypt(encrypted, the_key).toString(CryptoJS.enc.Utf8);
    const parsed = JSON.parse(decrypted);
    return parsed;
}
