<b>AI摘要</b>
|
||
<p id="ai-output">这篇文章介绍了作者如何利用Service Worker在现代浏览器中实现一个简单的反向代理功能，以提供博客的备份和离线访问。作者原本希望通过Service Worker在用户浏览器中运行一个Web服务器来存储博客副本，但发现 tar.gz 文件的处理需要第三方库且难以找到适用的解决方案，尤其是对于tar文件的处理。作者最终选择使用Service Worker作为反向代理，将请求转发到其他网站，如GeoCities风格的静态网站托管平台，实现了类似的效果。这个过程中，作者体验到了浏览器功能的强大，并认为Service Worker在离线场景中有更大的潜力，尽管在他的例子中并没有充分展示这种优势。</p>

<p>前段时间在和群友聊天的时候，提到了我博客的<a href="/2022/02/14/move.html">分发方案</a>，这么多年过去之后我已经在很多平台上<a href="/proxylist.html">分发</a>了我的博客，不过这只是多重冗余，并不算去中心化（虽然我也有向IPFS同步，不过IPFS还得pin，也不太可靠）……所以这么看来，我的博客似乎还不算极其可靠😂？但其实不完全是这样。因为除了向不同平台的分发，我的博客还有一个全文搜索的功能。更重要的是，之前做<a href="/2024/10/01/suggest.html">文章推荐功能</a>时，会把整个博客所有文章的文字存到访客浏览器的localStorage中。这么说来，只要有人访问了我博客的文章，他们的浏览器中就会保存一份我博客文章的完整文本副本。从这个角度看，可靠性应该算是相当高了吧？ </p><p>
|
||
不过我之前的分发方案里还记录了一点，在GitHub Pages以外的平台我还打包了一份全站生成后的代码，之所以要全站打包，也是希望我的博客能尽可能的分发，考虑到几乎所有的Linux发行版一定有tar，而不一定有zip，所以我最终打包成了tgz格式。如果能让访客下载这个全站打包好的副本，相比于浏览器里只存储了文章文字的全文数据，这应该是一个更好的备份方式吧？毕竟我的博客本身也是我的作品……所以这个压缩包到底有什么地方可以用到呢？ </p><p>
|
||
这时候我想起来，现代的浏览器功能已经非常强大了，甚至在浏览器里直接运行一个Web服务器也完全没问题。如果能让访客在浏览器里下载那个压缩包并运行一个Web服务器，那就相当于在他们本地设备上部署了一份我的博客副本。这样一来，除了我自己搭建的网站之外，这些访客的本地也运行着一个我的博客实例😆（当然，这份副本只有访客自己能看到）。</p>

<p>想要在浏览器上运行Web服务器其实很简单，那就是使用Service Worker，它可以完全离线在浏览器上工作。格式的话和以前写过的Cloudflare Worker非常相似，毕竟Cloudflare Worker就是模仿Service Worker的方式运行啊😂，所以我要是想写Service Worker应该很简单。 </p><p>
|
||
有了执行的东西之后就是存储，在Service Worker上存储可以用Cache Storage，用它的话不仅可以保存文件的内容，还可以保存响应头之类的东西，用来和Service Worker配合使用非常的方便，不过既然是Cache，它的可靠性就不能保证了，浏览器很可能在需要的时候清除缓存内容，所以相比之下用IndexedDB应该会更可靠一些。 </p><p>
|
||
那么接下来就该处理我的tgz文件了，tgz的本质是tar文件被gzip压缩之后的东西。浏览器解压gzip倒是简单，可以用Compression Stream API，但它也只能处理gzip了……对于tar的处理似乎就必须用第三方库。而tar的库在网上搜了搜似乎很少，网上找了个<a href="https://github.com/gera2ld/tarjs">tarjs</a>库，文档写的也看不懂，⭐️也很少，看来是有这个需求的人很少啊，而且还要用现代JS那种开发方式，要用什么npm之类的。在<a href="/2025/07/24/screenshot.html">上一篇文章</a>我就说过我不是专门写前端的，对在自己电脑上安装Node.js之类的东西很反感。后来问AI也完全写不出能用的代码，估计这个功能还是太小众了……另外又想到除了这个问题之外还要处理网站更新的时候该怎么通知Service Worker之类乱七八糟的事情……所以只好作罢😅。</p>

|

|

<p>这么看来离线运行我的博客似乎有点麻烦，不过既然都研究了一下Service Worker，不如想想其他能做的事情……比如当作反向代理？虽然在浏览器上搞反向代理好像意义不是很大……但值得一试。我之前见过一个项目叫做<a href="https://github.com/EtherDream/jsproxy">jsproxy</a>，它是用Service Worker实现的正向代理，这给了我一些启发。我在之前研究分发方案的时候发现了一些模仿GeoCities的复古静态网站托管平台，比如<a href="https://neocities.org">Neocities</a>和<a href="https://nekoweb.org">Nekoweb</a>。它们需要通过网页或API才能上传网站，不太方便使用CI/CD的方式部署。但是我又觉得它们的社区很有意思，所以想用Service Worker的方式反代到我的网站，显得我的网站是部署在它们上面一样。 </p><p>
|
||
这个做起来非常简单，其实就和我以前用<a href="/2021/03/02/workers.html#%E9%A6%96%E5%85%88%E7%BB%99%E8%87%AA%E5%B7%B1%E6%90%AD%E4%B8%AA%E5%8F%8D%E4%BB%A3">Cloudflare Worker搭建反代</a>几乎完全一样，遇到请求之后直接通过Fetch获取内容然后再返回就行，唯一不同的就是浏览器存在跨域策略，在跨域时只有对应网站存在合适的响应头才可以成功请求，还好我用的Pages服务大多都允许跨域。但是在我实际测试的时候发现这个允许跨域的等级不太一样，比如GitHub Pages的响应头里包含<code class="language-plaintext highlighter-rouge">Access-Control-Allow-Origin: *</code>，但是不允许OPTIONS方式请求，另外如果要修改请求头，在响应头里还要一一允许相应的请求头才行……当然对于这种问题解决起来很简单，就和我之前写的<a href="/2025/04/08/feed.html">订阅源预览</a>一样，用<a href="https://github.com/Zibri/cloudflare-cors-anywhere">cloudflare-cors-anywhere</a>搭建的CORS代理就可以，有了这个就可以轻松使用Service Worker反代其他网站了。 </p><p>
|
||
当然对我来说其实有<code class="language-plaintext highlighter-rouge">Access-Control-Allow-Origin: *</code>就够了，我也不需要花里胡哨的请求方式，也不需要在请求头和请求体里加什么莫名其妙的东西，所以对我来说直接请求我的某一个镜像站就可以，于是代码如下： </p><p>

<p>虽然折腾了半天没能增强我博客的可靠性……但是体会到了现代浏览器的强大之处，难怪前几年会提出ChromeOS和PWA之类的东西，原来浏览器功能还是相当强大的，用了Service Worker以后即使是纯前端也可以有和使用服务器一样的体验，在过去的浏览器中要是想实现这样的功能……好像也不是不可能😂，用AJAX加服务器使用伪静态策略其实是可以做到的……其实Service Worker的功能更多还是在离线时使用的，我这个例子好像没体现它的优势😆。 </p><p>
|
||
但总的来说相比以前想要实现这种反代的功能代码还是更清晰，也更简单了，也许以后如果有机会我又有心思让博客在访客浏览器上离线运行，那就可以体现Service Worker真正的优势了🤣。</p></main>
