调用api wx.startFacialRecognitionVerify

第一步:

      // 修改方法
      expertUpdate() {

       let _this = this
       wx.startFacialRecognitionVerify({
          name: _this.registerForm.realName, //身份证名称
          idCardNumber: _this.registerForm.idCard, //身份证号码
          checkAliveType: 1, //屏幕闪烁(人脸核验的交互方式，默认0,读数字)
          success(res) {
            
         console.log(res)  //认证结果
         if(res.errCode == 0){
          //识别成功  这个时候可以调后端的接口 （带着返的res.verifyResult）
          _this.verifyUser(res.verifyResult)
        }else{
        	tipInfo("识别失败")
        }
          },
          complete(res) {
          console.log(res)
          },
          fail(e) {
            console.log("err", err)//失败处理方法
           wx.showToast('请保持光线充足，面部正对手机，且无遮挡')
          }
   
        })
}

第二步:调方法校验后端的接口

 // 人脸识别  根据上一个方法把verify_result传过来  //后端的校验接口


      verifyUser(verify_result) {
        //看后端实际要求 要传身份证号码不
        let obj = {
          uuid: this.infoForm.idCard,
          verify_result: verify_result
        }

      //后端接口=>verifyUser
        verifyUser(obj).then(res => {
          if (res.code == '0') {
            this.$refs.uForm.validate().then(res => {
              let obj = {
                pkid: uni.getStorageSync('expert_info').pkid,
                memberId: uni.getStorageSync('expert_info').memberId,
                avatar: this.fileList1[0].url,
                realName: this.infoForm.realName,
                orgName: this.infoForm.orgName,
                idCard: this.infoForm.idCard,
                province: this.infoForm.province,
                city: this.infoForm.city,
                district: this.infoForm.district,
                phone: this.infoForm.phone,
                professorLevel: this.infoForm.professorLevel,
                adept: this.infoForm.adept,
                intro: this.infoForm.intro,
                smsCode: this.infoForm.smsCode,
                annex: this.fileList2,
              }
             //修改方法
              expertUpdate(obj).then(res => {
                console.log(res, '修改成功了吗');
                if (res.code == '0') {
                  uni.$u.toast('修改成功', 5000)
                  uni.navigateBack()
                  //修改成功后 是返回上一步  还是跳转其他页面 根据实际情况
                } else {
                  uni.$u.toast(res.msg, 5000)
                }
              })
              console.log(res);
      
            }).catch(error => {
              console.log(error);
              uni.$u.toast('请先按要求填写', 5000)
            })
          }
        })
      
      },

注释:完整方法这个是实现小程序个人信息完善,加了一个判断,如果输入框没有值则需要走人脸识别验证方法如果有值只是修改其他项就不需要验证修改完成之后名字和身份证号码直接禁用

 // 修改方法
      expertUpdate() {
        if (this.fileList1.length == 0) {
          uni.$u.toast('请上传头像')
          return false
        }
        // 判断 realName 是否为空
        if (!this.infoForm.realName) {
          uni.$u.toast('请填写姓名');
          return false;
        }
        // 验证 realName 是否为中文
        const chineseRegex = /^[\u4e00-\u9fa5]+$/;
        if (!chineseRegex.test(this.infoForm.realName)) {
          uni.$u.toast('姓名必须为中文');
          return false;
        }
        // 判断 idCard 是否为空
        if (!this.infoForm.idCard) {
          uni.$u.toast('请填写身份证号码');
          return false;
        }
        // 验证 idCard 是否符合身份证标准
        const idCardRegex = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
        if (!idCardRegex.test(this.infoForm.idCard)) {
          uni.$u.toast('身份证号格式不正确');
          return false;
        }
        if (this.fileList2.length == 0) {
          uni.$u.toast('请上传附件')
          return false
        }
        if (this.infoForm.intro.length > 200) {
          uni.$u.toast('简介字数不能超过200字!')
          return false
        }
        if (!this.flag) {
          let _this = this
          wx.startFacialRecognitionVerify({
            name: _this.infoForm.realName,
            idCardNumber: _this.infoForm.idCard,
            checkAliveType: 1,
            success(res) {
              console.log(res)
              _this.verifyUser(res.verifyResult)
              // console.log(res)
              // uni.navigateBack()
            },
            complete(res) {
              console.log(res)
            },
            fail(e) {
              // console.log(res)
              // console.log(_this.infoForm.realName)
              // console.log(_this.infoForm.idCard)
              console.log(e, 'fail')
            }
          })
