最新提示:微信小程序上线前审核,要求你必须使用微信自带活体识别的sdk,自己开发的不会被允许通过,望周知!
这相信有很多小程序都会用,为啥呢?因为小程序压根不得给你用户身份证信息,所以替换做法就是你让用户上传身份证照片,然后你在人脸识别,判断是同一个人后,再将你信息录入数据库
1、在小程序端的活体识别方法
1、uniapp camera组件拍照 takePhoto
2、uniapp camera组件录像 startRecord
3、uniapp live-pusher组件 视频推流方式文章来源:https://www.toymoban.com/news/detail-610945.html
2、拍照方式实现人脸识别
因为项目要得紧,所以我这里使用最简单的拍照,拍八张,定时器每秒一张(后端用的是百度人脸识别api,有照片活体识别和视频活体识别),然后一起传给后端,不过更好的做法是拍一张传一张,成功则完成,识别失败那就再调拍照api,总的时间不超过十秒,在用户端看来是没有任何异常的。文章来源地址https://www.toymoban.com/news/detail-610945.html
