uniapp结合萤石视频ezuikit.js的爬坑记录

# 1.前言 #

由于开发需要，项目需要接入萤石的视频监控。萤石官方提供了三种协议的的视频方式，hls，rtmp，ezopen。三种协议是视频直播有一定差别，由于hls有十多秒的延迟，不符合项目的要求，并且因为hls，rtmp需要用vedio标签，uniapp会对video标签初始化，

所以本人采用了延迟最低的ezopen。

在使用的过程中遇到了很多很多的坑，即使在尝试别人的解决方案依旧无用。希望这篇文章对使用的同学有所帮助。

# 2.初探 #

看看官方文档，他有一个[UIKit JavaScript][]的demo示例，请使用的同学先下载官方demo示例。同时看看官方文档他是这么描述使用的：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTEyMDA1NjI_size_16_color_FFFFFF_t_70][]

第一步：首页把下载的uikit的js文件放到static下，**注意不能放到其他文件夹下，否则在配置decoderPath地址时，会找不到，导致报错**

第二步：在需要的vue文件下引用uikit.js

<template>
    	<view class="">
    		<uni-nav-bar @clickLeft="clickLeft" left-icon="back" left-text="返回" title="监控详情"></uni-nav-bar>
    		<view class="">
    			<view id="myPlayer"></view>
    		</view>
    	</view>
    </template>
    <script>
    	import EZUIKit from '../../static/js/ezuikit.js'
    	export default {
    		data() {
    			return {
    				device_id: '',
    				accessToken: ""
    			}
    		},
    		onLoad(options) {
    			this.device_id = options.device_id
    			this.accessToken = options.accessToken
    			this.getAddr()
    		},
    		methods: {
    			async getAddr() {
    				let url=`ezopen://open.ys7.com/${this.device_id}/1.hd.live`
    				var player = new EZUIKit.EZUIPlayer({
    					id: 'myPlayer',
    					url: url,
    					autoplay: true,
    					accessToken: this.accessToken,
    					decoderPath: 'static/js/',
    					width: 600,
    					height: 400,
    				});
    				player.play();
    			},
    			clickLeft() {
    				uni.navigateBack({
    					delta: 1
    				});
    			},
    		}
    	}
    </script>
    
    <style>
    </style>

常见的报错信息：

1.注意decoderPath如果写错，会出现报错信息，JSPlugin没有定义，点开报错信息，仔细观看官方文档的同学应该都发现了，其实这个JSPlugind对应就是下图的decorderPath路径，如果你的路径写错了肯定是JSPlugin未定义，

![20210305155529188.png][]

那这个路径到底怎么书写，需要把decoderPath写成'static/js/'才行

2.报错信息

这个报错不知道什么原因导致的，但是给初始化方法加个定时器就好了，知道的小伙伴可以评论告诉我哦！

getAddr() {
    				setTimeout(()=>{
    					let url=`ezopen://open.ys7.com/${this.device_id}/1.hd.live`
    					var player = new EZUIKit.EZUIPlayer({
    						id: 'myPlayer',
    						url: url,
    						autoplay: true,
    						accessToken: this.accessToken,
    						decoderPath: 'stic/js/',
    						width: 600,
    						height: 400,
    					});
    					player.play();
    				},500)
    			},

### **但是在PC端运行正常，但是真机测试时监控出不来！！！！！** ###

发现uniapp结合萤石云必需要写h5页面，需要用到uniapp的webview组件，且app的h5页面要放到项目里面，微信小程序的h5页面需要放到服务器上。

具体操作：

**微信小程序：**

webview.vue文件

<template>
    	<view class="webview">
    		<web-view :src="url" id="webcon" @message="handleMessage">
    		</web-view>
    	</view>
    </template>
    
    <script>
    	export default {
    		data() {
    			return {
    				url: '',
    				device_id: '',
    				accessToken: ''
    			}
    		},
    		onLoad(options) {
    			this.device_id = options.device_id
    			this.accessToken = options.accessToken
                //uniapp小程序
    			this.url = "https://wx.hnyfwlw.com/wechat?device_id=" + this.device_id +         "&accessToken=" + this.accessToken
    
                //uniapp App
                this.url = "/static/h5.html?device_id=" + this.device_id + "&accessToken=" + this.accessToken
    			//设置 webview 界面的状态栏的 title
    			uni.setNavigationBarTitle({
    				title: '监控详情'
    			});
    		},
    
    	}
    </script>
    
    <style>
    	.webview {
    		width: 100vw;
    		height: 100vh;
    	}
