摄像头抓拍保存到本地，我们在本地搭建网络盘，将抓拍图片放到指定目录，即上传到本地服务器，不用走接口上传，

初始化没有设置抓图保存路径，会保存失败，所以第一次需要选择抓拍保存路径，之后就不需要设置了

注意：

1、在public新建hk文件夹，将官方demo需要的依赖复制到文件夹下，在public文件加下新建iframe.html文件，

iframe.html

<!doctype html>
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta http-equiv="Pragma" content="no-cache" />
    <meta http-equiv="Cache-Control" content="no-cache, must-revalidate" />
    <meta http-equiv="Expires" content="0" />
</head>
<style type="text/css">
html, body {
    margin: 0;
    padding: 0;
    border: 0;
}
.plugin {
    width: 300px;
    height: 200px;
}
</style>
<body>
    <div id="divPlugin" class="plugin"></div>
</body>
<script src="./hk/jquery-1.7.1.min.js"></script>
<script src="./hk//webVideoCtrl.js"></script>
<script>

$(function () {

    var oPlugin = {
        iWidth: 300,            // plugin width
        iHeight: 200            // plugin height
    };
    var g_iWndIndex = 0;
    // ��ʼ�����������������
    WebVideoCtrl.I_InitPlugin(oPlugin.iWidth, oPlugin.iHeight, {
        bWndFull: true,
        iWndowType: 1,
        cbInitPluginComplete: function () {
            //console.log(document.querySelectorAll('#divPlugin'),'0123')
            WebVideoCtrl.I_InsertOBJECTPlugin("divPlugin");
        },
    });

});

</script>
</html>

2、新建webVideo.vue组件


<template>
  <div>
    <iframe class="iframe" src="iframe.html" frameborder="0"></iframe>
    <iframe class="iframe" src="iframe.html" frameborder="0"></iframe>
    <div class="bottom">
      <div class="select_box" v-if="selectShow">
        <el-input
          id="previewPicPath"
          v-model="previewPicPath"
          placeholder="请选择存储路径"
        >
          <el-button
            slot="append"
            @click="clickOpenFileDlg('previewPicPath', 0)"
            >浏览</el-button
          >
        </el-input>
        <el-button type="primary" @click="clickSetLocalCfg">设置</el-button>
      </div>
      <el-button @click="clickCapturePic">拍照</el-button>
    </div>
  </div>
</template>

<script>
