同样的问题，调试的过程中，发现传送参数0、1、2均为屏幕闪烁，无法调用读数。

wx.startFacialRecognitionVerify({
    checkAliveType: 0,//屏幕闪烁(人脸核验的交互方式，默认0,读数字)
    name: name, //姓名
    idCardNumber: idCardNumber, //身份证号
    //人脸识别成功回调通知
    success: function (res) {
        var verifyResult = res.verifyResult;
        if (res.errCode === 0 || 'startFacialRecognitionVerify:ok' == res.errMsg) {
            wx.showModal({
                title: '提示',
                showCancel: false,
                content: "验证成功",
                success: function (res) {
                    
                }
            });
        } else {
            wx.showModal({
                title: '提示',
                showCancel: false,
                content: "人脸识别失败！",
                success: function (res) {}
            });
        }
    },
    //人脸识别失败的回调通知
    fail: function (res) {
        console.log(res)
        wx.showModal({
            title: '提示',
            showCancel: false,
            content: "人脸识别失败！" + res.errMsg,
            success: function (res) {

            }
        });
    },
    complete:function(res){
        console.log("complete:",res)
    }

});
