本文介绍了小程序实现人脸识别功能,分享给大家,具体如下:
	文档中心:https://ai.baidu.com/docs#/Begin/a2bbf4b2
	接入流程
	1. 按照文档获取AppID、API Key、Secret Key,进行Access Token(用户身份验证和授权的凭证)的生成
	const getBaiduToken = function () { return new Promise((resolve, reject) => {  //自行获取APIKey、SecretKey  const apiKey = APIKey;  const secKey = SecretKey;  const tokenUrl = `https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=${apiKey}&client_secret=${secKey}`;  wx.request({   url: tokenUrl,   method: 'POST',   dataType: "json",   header: {    'content-type': 'application/json; charset=UTF-8'   },   success: function (res) {    resolve(res);   },   fail: function (res) {    wx.hideLoading();    wx.showToast({     title: '网络错误,请重试!',     icon: 'none',     duration: 2000    })    reject(res);   },   complete: function (res) {    resolve(res);   }  }) })} 	2. 选择人脸识别-->人脸检测,人脸识别接口分为V2和V3两个版本,确认在百度云后台获得的是V2还是v3版本接口权限。
	//封装识别方法const getImgIdentify = function(tokenUrl, data){ return new Promise((resolve, reject) => {  const detectUrl = `https://aip.baidubce.com/rest/2.0/face/v3/detect?access_token=${tokenUrl}`;  wx.request({   url: detectUrl,   data: data,   method: 'POST',   dataType: "json",   header: {    'content-type': 'Content-Type:application/json; charset=UTF-8'   },   success: function (res) {    resolve(res);   },   fail: function (res) {    wx.hideLoading();    wx.showToast({     title: '网络错误,请重试!',     icon: 'none',     duration: 2000    })    reject(res);   },   complete: function (res) {    resolve(res);   }  }) })} 	3. 调用识别方法
	getBaiduToken().then((res) => { let token = res.data.access_token; let data = {  "image": self.data.img,  "image_type":"URL",  "face_field":"ge,beauty,expression,face_shape,gender,glasses,landmark,race,quality,eye_status,emotion,face_type" } util.getImgIdentify(token, data).then((res)=>{  //百度接口返回的结果  let score = parseInt(res.data.result.face_list[0].beauty);  self.setData({   score: score,  }) })}) 	4. 结果如下:
