小程序实现人脸识别功能(百度ai)

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"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);
   }
  })
 })
}

//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"json",
   header: {

    resolve(res);
   },

    wx.hideLoading();
    wx.showToast({
     title: '网络错误，请重试！',
     icon: 'none',
     duration: 2000
    })
    reject(res);
   },
   complete: function (res) {
    resolve(res);
   }
  })
