GoIndex是部署在Cloudflare Workers上的Google Drive目录索引程序。不需要提供服务器。它可以直接列出您Google云端硬盘中的所有文件。看起来是这样的：
Github用户Donwa在其goindex项目中开发了这种快速部署方法。这是我遵循的摘要步骤 working.
生成工人代码
1 生成Cloudflare工人代码：
1.1获取Google身份验证代码
1.1获取Google身份验证代码
1.2获取Google云端硬盘文件夹ID
通过 visiting the google drive folder, you will find the url from browser such as “//drive.google.com/drive/u/0/folders/kjkfhieriiiweor023438”. The folder id is the string behind “//drive.google.com/drive/u/0/folders/”
将字符串“ kjkfhieriiiweor023438”复制到 路径ID（默认为root）。如果您未放置任何内容，则默认为根文件夹。
您也可以输入密码来保护您的文件夹。默认密码为index。您可以更改为自己喜欢的一种。空白表示没有密码。
1.3构建代码
单击生成，代码将在文本框中生成。
该代码将如下所示。复制期间不要错过任何字符。

将代码部署到Cloudflare工作者
2 将代码安装到Cloudflare中的新工作人员
Create a new workers as I described in my previous post: "使用Cloudflare工作者建立反向代理"
另一个选择是使用您自己的域来访问它，但是我发现它通常并不那么稳定。使用worker.dev链接将非常稳定。 （//gd.51sec.workers.dev/)
Create a sub domain record, and mapping a Workers route to this new created Workers program. You can check the steps in this post: "设置CloudFlare Workers以使用您自己的域"
我确实为此创建了gd.51sec.org，但是它不如原始Cloudflare域那么稳定： //gd.51sec.workers.dev/
注意：此方法更加简便快捷。但是有时候，系统会变得很忙，而且速度很慢。

将代码部署到Cloudflare工作者
另一个选择是使用您自己的域来访问它，但是我发现它通常并不那么稳定。使用worker.dev链接将非常稳定。 （//gd.51sec.workers.dev/)
创建一个子域记录，然后将一个Workers路由映射到这个新创建的Workers程序。您可以查看这篇文章中的步骤：设置CloudFlare Workers以使用您自己的域“
我确实为此创建了gd.51sec.org，但是它不如原始Cloudflare域那么稳定： //gd.51sec.workers.dev/
注意：此方法更加简便快捷。但是有时候，系统会变得很忙，而且速度很慢。

3 一主题支持上传功能
这是您可以复制使用，更改某些ID，令牌，机密设置的所有代码。
主题2 –支持上传
4 这是另一个goindex主题，它具有更多功能和更快的速度，但没有上载。

由于许多人使用Google云端硬盘来构建云端硬盘堆栈并通过IFTTT收集链接以建立索引，这是否也可以成为增加索引的另一种方式？由于Cloudflare基本上将此工作人员站点部署到了其所有节点，因此，这似乎是一种增强链接到Google云端硬盘中的文档的好方法
好主意;心存善念;睿智哲思。我不确定这是否是增加索引的好方法。我确实看到一些网站正在收集这些Google驱动器链接，并将它们按类别放入网站书签页面。
