使用Java开发人脸融合(换军装等)并接入微信小程序

摘要：先看一个演示图片图片不是静止哦只是慢如何接入人脸融合功能到小程序创建一个应用登录腾讯，创建并勾选相关接口即可。具体可以参考项目调用腾讯接口。小帅丶已经封装成。使用阿里云腾讯云都可以哦。

先看一个演示图片(图片不是静止哦只是慢)

如何接入人脸融合功能到小程序

创建一个AI应用

https://ai.qq.com/cgi-bin/con... 登录腾讯AI，创建并勾选相关接口即可。

记得复制APPID APPKEY
使用Java接入该功能

创建一个SpringMVC工程，包含上传相关jar。或者SpringBoot工程也行。鄙人后端还在完善并没有完全开源。具体可以参考https://gitee.com/xshuai/xai 项目

Java调用腾讯AI接口。小帅丶已经封装成SDK。也是开源的 https://gitee.com/xshuai/taip

如果使用maven搭建。直接pom引入即可哦

微信小程序代码实现

小帅一点资讯小程序代码是开源的哦

学习并使用了微信小程序scroll-view组件

相关代码请移步gitee查看 https://gitee.com/xshuai/weix...

微信小程序上传限制为2048kb。相关图片过多超了限制。因此需要用到云存储。使用阿里云 腾讯云都可以哦。在亲测的情况下发现。即使云储存域名不在小程序里面添加也是可以正常访问哦

以上就是接入的整体流程 可以扫码体验哦
