代码中的masterSecret需要修改为极光后台的masterSecret,appKey需要修改为极光后台的appKey


这里给大家分享我在网上总结出来的一些知识,希望对大家有所帮助

记录--uniapp开发安卓APP视频通话模块初实践

视频通话SDK用的即构的,uniapp插件市场地址

推送用的极光的,uniapp插件市场地址

即构音视频SDK

uniapp插件市场的貌似是有些问题,导入不进项目,直接去官网下载,然后放到项目下的 nativeplugins 目录下,在配置文件中填入即构后台的appID和AppSign,接下来就可以开干了

准备两个页面

首页:/pages/index/index

// 新建一个按钮 <button @click="sendVideo">发送视频邀请</button>  // 发送事件,主动发送直接进入下一个页面即可 sendVideo(){     uni.navigateTo({         url: '/pages/call/call'     }) }

通话页:pages/call/call 这个页面会复杂一点

注意这个页面为 nvue 页面

先把所有代码都列出来,再一一做说明

<template>     <view>         <view v-if="status === 1" class="switch-bg" :style="{'height': pageH + 'px'}">             <view class="top-info u-flex" style="flex-direction: row;">                 <image src="http://cdn.u2.huluxia.com/g3/M02/32/81/wKgBOVwN9CiARK1lAAFT4MSyQ3863.jpeg" class="avatar">                 </image>                 <view class="info u-flex u-flex-col u-col-top">                     <text class="text">值班中心</text>                     <text class="text" style="margin-top: 10rpx;">正在呼叫</text>                 </view>             </view>                 <view class="switch-handle u-flex u-row-center" style="flex-direction: row;

说明:

代码中的masterSecret需要修改为极光后台的masterSecretappKey需要修改为极光后台的appKey

view 部分:

status=1 中的为主动呼叫方进入页面是初始显示内容,最重要的是 hangUp 方法,用来挂断当前邀请

status=2 中的为被邀请者进入页面初始显示的内容,有两个按钮,一个hangUp挂断,一个switchOn 接听

status=3中为接听后显示的内容(显示自己与对方视频画面)

script 部分:

最开始五行是引入相关SDK的。极光推送、即构音视频

onLoad 中有一个判断语句,这个就是用于判断进入页面时是主动呼叫方还是被动答应方的,显示不同内容

if(opt.status == 2){		// 带参数 status=2时代表被呼叫     this.status = parseInt(opt.status) } if(!opt.status){			// 主动呼叫、需要发推送消息     this.getPushCid(); }

sendCustomCommand 是用来在房间内发送自定义信令的,用于通知另一个人是接听了还是挂断了通话

getPushCid 是获取极光推送的cid,避免重复发送推送消息(极光推送)

changeCamera 切换摄像头

revocationPushMsg 撤销推送(主动呼叫方挂断通话)

sendPushMsg 发推送消息

initZegoExpress 初始化即构音视频SDK相关,与官网demo,此处我做了小改动

login 登录即构房间

logout 退出即构房间

publish 推流

destroyEngine 销毁音视频实例

removeStreams 删除流

encode base64转码

在App.vue中进行极光推送的初始化

onLaunch: function() {     console.log('App Launch')     // #ifdef APP-PLUS     if (uni.getSystemInfoSync().platform == "ios") {         // 请求定位权限         let locationServicesEnabled = jpushModule.locationServicesEnabled()         let locationAuthorizationStatus = jpushModule.getLocationAuthorizationStatus()         console.log('locationAuthorizationStatus', locationAuthorizationStatus)         if (locationServicesEnabled == true && locationAuthorizationStatus < 3) {             jpushModule.requestLocationAuthorization((result) => {                 console.log('定位权限', result.status)             })         }           jpushModule.requestNotificationAuthorization((result) => {             let status = result.status             if (status < 2) {                 uni.showToast({                     icon: 'none',                     title: '您还没有打开通知权限',                     duration: 3000                 })             }         })          jpushModule.addGeofenceListener(result => {             let code = result.code             let type = result.type             let geofenceId = result.geofenceId             let userInfo = result.userInfo             uni.showToast({                 icon: 'none',                 title: '触发地理围栏',                 duration: 3000             })         })          jpushModule.setIsAllowedInMessagePop(true)         jpushModule.pullInMessage(result => {             let code = result.code             console.log(code)         })          jpushModule.addInMessageListener(result => {             let eventType = result.eventType             let messageType = result.messageType             let content = result.content             console.log('inMessageListener', eventType, messageType, content)              uni.showToast({                 icon: 'none',                 title: JSON.stringify(result),                 duration: 3000             })         })      }      jpushModule.initJPushService();     jpushModule.setLoggerEnable(true);     jpushModule.addConnectEventListener(result => {         let connectEnable = result.connectEnable         uni.$emit('connectStatusChange', connectEnable)     });      jpushModule.addNotificationListener(result => {         let notificationEventType = result.notificationEventType         let messageID = result.messageID         let title = result.title         let content = result.content         let extras = result.extras         console.log(result)         this.$util.router(`/pages/public/answer?status=2`)     });      jpushModule.addCustomMessageListener(result => {         let type = result.type         let messageType = result.messageType         let content = result.content         console.log(result)         uni.showToast({             icon: 'none',             title: JSON.stringify(result),             duration: 3000         })     })      jpushModule.addLocalNotificationListener(result => {         let messageID = result.messageID         let title = result.title         let content = result.content         let extras = result.extras         console.log(result)         uni.showToast({             icon: 'none',             title: JSON.stringify(result),             duration: 3000         })     })     // #endif },

不要忘了在最开始引入极光推送的插件

var jpushModule = uni.requireNativePlugin("JG-JPush")

官方demo的代码,直接拿过来了。。

其中最重要的就是下面这段,用来监听获取推送消息的,这里如果收到推送消息自动跳转至通话页面,也就是上面status=2的状态下

jpushModule.addNotificationListener(result => {     let notificationEventType = result.notificationEventType     let messageID = result.messageID     let title = result.title     let content = result.content     let extras = result.extras     console.log(result)     this.$util.router(`/pages/call/call?status=2`) });
