代码踩坑经验分享

前端代码布局：布局设计和优化占用了我大量的时间，原因是我是后端工程师，对css样式不专业，哈哈，欢迎精通前端样式的小伙伴加入，我们后续会有大量的前端需求要实现，一起学习，共同进步，把创意落地到产品，技术就是生产力，
前端图片压缩：由于阿里云的接口参数对图片尺寸有严格要求（图片格式：PNG、JPG、JPEG、BMP、TIFF、WEBP等。图片大小：小于3MB。图片分辨率：小于2000×2000），因此需要前端先判断图片大小，苹果手机的拍摄的照片普遍都超过3M，和大于2000X2000分辨率，所以需要先进行compress压缩到小于3MB，并裁剪到小于2000X2000分辨率，在这里也坑了我好久，好在我能熬夜加班，最终找到了处理的方法，但是不算很完美，打算后面持续迭代，也欢迎做过压缩裁剪产品的小伙伴指导一下。

产品总结

通过开发这款AI人脸美妆系统，我们将为用户提供更加智能、个性化的美妆体验。通过准确的人脸分析和美妆效果叠加，用户可以轻松实现虚拟试妆和实时美妆的功能，并可以保存和分享美妆效果图像。同时，通过个性化的妆品推荐，我们也将帮助用户更好地选择适合自己的美妆产品。通过不断改进和迭代，我们将努力提升系统的性能和用户体验，满足用户对美妆的不同需求。
