问题描述：

机型：华为mate20X 系统版本：10.0.0.195 微信版本：7.0.13

用户启动人脸拍照，照片拍完后，点击完成按钮（‘完成’按钮需要点击多次），这时还未走入success和fail回调就会触发页面刷新，刷新后需要重新拍照，有时候拍一次可成功，多数情况需要多次重复操作拍照才能上传成功。

视频中出现的提示“二维码已失效”是因为用户点击完成后，又重新请求这个二维码地址了。

视频如下：

代码如下：

 // 点击开始拍照
 document.querySelector('#tips').onclick = function (){

    wx.chooseImage({

        sizeType: ['compressed'],
        sourceType: ['camera'],
        success: function (res) {
            alert("chooseImage--success")
            // "开始拍摄"按钮隐藏
            $("#tips").css("display","none");
            $("#chooseImage1").css("display","none");
            var img1 = $('#chooseImage1');
            //返回选定照片的本地ID列表，localId可以作为img标签的src属性显示图片
            var imgLocalId = res.localIds;
            if(!imgLocalId){
                fnPicInfo('',imgLocalId,'choose','fb',JSON.stringify(res));
            }
            $("#returnImg").attr('src',imgLocalId);
