1.背景需求
- 通过EasyNVR接口,二次开发集成在自己的原有的web业务系统上云台控制及实时直播功能,demo效果入下。
- demo是通过vue-cli脚手架搭建起来,简单说一下,目录结构
- 对easy-player不了解的这是播放器插件地址可以参看 https://www.npmjs.com/package/easy-player
- 这里主要讲解一下App.vue内容文件
<template><div id="app"><!-- 测试鉴权 如果鉴权已关闭请忽略 --><div class="div-btn"><el-button-group><el-button size="mini" type="success" @click="login">测试登录</el-button><el-button size="mini" type="success" @click="loginout">测试退出</el-button><el-button size="mini" type="success" @click="testapi">测试鉴权</el-button></el-button-group></div><el-row><!-- 播放窗口组件 --><el-col :span="12"><EasyPlayer :videoUrl="videoUrl" fluent autoplay live stretch></EasyPlayer><el-input v-model="input" placeholder="请输入播放地址接口" size="mini"></el-input><p>列如:http://127.0.0.1:10800/api/v1/getchannelstream?channel=1&protocol=RTMP</p><el-button class="player-button" size="mini" type="success" @click="player">播放</el-button></el-col><!-- 云台控制组件 --><el-col :span="12"><div class="control-box"><!-- 云台控制按钮列表 --><span @click="testControl('zoomin')"><i class="el-icon-circle-plus-outline"></i></span><span @click="testControl('up')"><i class="el-icon-arrow-up"></i></span><span @click="testControl('zoomout')"><i class="el-icon-remove-outline"></i></span><span @click="testControl('left')"><i class="el-icon-arrow-left"></i></span><span @click="testControl('stop')">停止</span><span @click="testControl('right')"><i class="el-icon-arrow-right"></i></span><span></span><span @click="testControl('down')"><i class="el-icon-arrow-down"></i></span><span></span></div></el-col></el-row></div>
