用uniCloud开发了一个性格测试小程序，已经完美发布【源码开源】

最近研究了uniCloud，并用uniCloud开发了一个性格测试小程序，已经发布到服务器，完美的发布到抖音，在抖音可以搜索到该小程序。

源码和视频教程都开源给大家了。小孟已经发布到抖音，全部的已经跑通，所以小伙伴可以拿去学习，没有任何的问题。

也出了详细的教程了！

视频的教程放在b站了，希望下坡伙伴，给个三连：

一，什么是uniCloud：

uniCloud是uni-app的云开发库，是 DCloud 联合阿里云、腾讯云，为开发者提供的基于 serverless 模式和 js 编程的云开发平台。

uniCloud基本抹平了不同云厂商的差异，如果你熟悉mongoDB，那么就很容易上手了!

现在用uniCloud可以大大的提高开发的效率，而且可以降低运维方面的成本，因为现在serverless还处于免费阶段。

当然也有很多的缺点，新手上手的话不是很快，很多东西也不支持，例如删除数据，竟然还要去调api。

最近小孟和老王研究了下，感觉还是可以搞的，于是就测试并发布了整个通用的版本，发布到了抖音，这个大家可以搞一下，抖音的流量你懂的，但是我们现在对赚钱不感兴趣。所以有熊伙伴想搞的，可以拿去源码学习，但是不要商用和贩卖！

这个系统小孟也开发了很久，有小伙伴说需要学习，狠狠心，给大家开源了，拿去学习吧，下面的图片，输入：unicloud

对于程序开发这块，需要不断的练习，不断的改bug，才能成长，遇到bug别慌，因为以后有改不完的bug！
