我先是调用checkIsSupportFaceDetect检查是否支持人脸识别，返回支持后才调用requestWxFacePictureVerify进行人脸识别，安卓没有问题，ios系统一直调不起，返回requestWxFacePictureVerify：fail，返回err_code的值为undefined
代码如下：
wx.ready(function () {
wx.invoke('checkIsSupportFaceDetect', {
}, function (res) {
if (res.err_code == 0) {
wx.invoke('requestWxFacePictureVerify', {
"appid": "wx03987249d26e8aa8",
"request_verify_pre_info": { 'name': name, 'id_card_number': id_card_number },
"checkAliveType": 2
}, function (ss) {
if (ss.err_code == 0) {
alert(ss.err_code);
} else {
alert(ss.err_code);
alert(ss.err_msg);
alert(ss.lib_version_code);
$.toptip(ss.err_msg, 2000, "error");
return;
}
})
} else {
$.toptip("该设备不支持人脸识别！", 2000, "error");
return;
}
})
})
}
具体代码如下：

你好，麻烦具体描述问题流程，提供出现问题的具体机型、微信版本号、系统版本号，以及能复现问题的代码片段https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html
我开发的是公众号网页而不是小程序哦，这怎么做复现问题代码片段？
具体的流程是：
1、点击人脸识别按钮，进入填写姓名和身份证号码页面
2、点击下一步时先调用checkIsSupportFaceDetect判断设备是否支持人脸识别
3、判断是后调用requestWxFacePictureVerify调起人脸识别页面。
到这一步后，安卓手机没有问题可以调出人脸识别页面，ios系统就调不出识别页面，ios系统调用requestWxFacePictureVerify后返回的数据如下：
{
err_code: undefined,
err_msg: requestWxFacePictureVerify:fail,
verify_result: undefined
}
