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 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. |
