如何缩短mongo ID以更好地在URL中使用? [英] How can one shorten mongo ids for better use in URLs?

问题描述

我已经建立了许多使用mongodb作为数据库后端的python驱动站点，并且对它的ObjectId系统非常满意，但是，我希望能够以较短的方式编码id，而无需构建映射集合或利用网址缩短程序服务.

I've built a number of python driven sites that utilize mongodb as a database backend and am very happy with it's ObjectId system, however, I'd love to be able encode the ids in a shorter fashion without building a mapping collection or utilizing a url-shortener service.

建议?成功的故事吗?

推荐答案

您可以将它们压缩为Base62数字.这样不会节省很多空间，但是每个ID确实可以为您节省几个字节.我的示例是Ruby，但是在Python中使用类似的方法并不难.

You could compress them as Base62 numbers. This doesn't save a lot of space, but it does save you a few bytes per ID. My example's Ruby, but similar usage in Python wouldn't be hard.

ree-1.8.7-2010.02 > User.first._id.to_s
 => "4c76f3dd98db74697500003b"

ree-1.8.7-2010.02 > User.first._id.to_s.to_i(16).base62_encode
 => "uMarF7LmpY3bNOSn"
