我是靠谱客的博主闪闪御姐，最近开发中收集的这篇文章主要介绍uni-app实现微信相机uni-app实现微信相机，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

uni-app实现微信相机

在微信小程序中直接使用uni.chooseMedia即可调用微信相机进行摄录。但为了保持体验的相似性，造一个微信相机的轮子是有必要的

因为小程序的胶囊很碍事，所以对UI进行了调整，功能按钮均移动到页面下方。

本相机支持照片及视频的摄录，拍摄后可进行预览、重拍。采用页面栈的形式进行传值。

使用例：ClockIn.vue（记得先在pages.json中注册）

<template>
	<view>
    <button @click="doCapture">点击摄录</button>
  	<image v-if="photoSrc" :src="photoSrc"></image>
  </view>
	<script>
  	export default {
      data() {
        return {
          photoSrc: ""
        }
      },
      methods: {
        doCapture(){
          uni.navigateTo({
          	url: '/pages/TakePhotoAndVideo?dest=photoSrc'
        	})
        }
      }
    }
  </script>
</template>

源代码：TakePhotoAndVideo.vue

<template>
  <view class="complex-camera">
    <video v-if="videoSrc" :src="videoSrc" style="width: 100vw; height:100vh;z-index: 9800;" autoplay="true" loop="true"
