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
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

说明：
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
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
在 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`)
});
