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

<!-- https://mvnrepository.com/artifact/cn.xsshome/taip -->

    <groupId>cn.xsshome</groupId>
    <artifactId>taip</artifactId>
    <version>4.2.1</version>

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.
