由于 小程序端 有camera组件 直接就可以调起摄像头 但是 app端是不支持这个标签的 所以只能用其他的方法 使用 nvue 中?live-pusher 组件
子组件?
<template>
<div>
<div class="livefater">
<div style="width: 300px;height: 300px;border-radius: 150px;overflow: hidden;">
<!-- orientation="horizontal" //设置垂直水平方向 -->
<live-pusher id='livePusher' ref="livePusher" class="livePusher" url=""

this.context = uni.createLivePusherContext("livePusher", this);
var that = this
uni.getSystemInfo({
success: function(e) {
// 计算导航栏高度
that.statusBar = e.statusBarHeight
// #ifndef MP

that.CustomBar = e.statusBarHeight + 50

由于 人脸一般是 原型 样式 但是默认的live-pusher 是正方形 而且层级是比较高的 其他普通元素标签是无法压住他的? 但是 cover-imgae的图片是可以压上去的?
父组件
<TestingFace :time="5000" @faceImg="faceImg" :message="message"></TestingFace>
faceImg 就是子组件传过来的 图片 message 是传过去的内容? time是倒计时的拍照时间,具体内容可以根据内容去加逻辑? ?注意 子父组件都是 nvue
?
