我来自中工，是一名大三学生，这学期我们系统学习了鸿蒙相关的课程，如ArkTS开发语言，TypeScript基础，ArkUI开发框架等等...今天简单的做了一个小程序，使用的工具是DevEco Studio,是老师推荐的比较适合初学者的一款软件，有很丰富的功能。以下就是我的作业内容。

首先打开DevEco Studio，点击Create Harmony Project,选择Empty Ability创建一个空文件，点击Next。

然后是项目的细节设计，分别是名字，存储地址，SDK，和设备样例。设置完毕后，点击Finish。

创建完成后，就是模版样例。

接下来就是代码的编写了。

代码如下：

const cloud = require('HarmonyAPI'); const crypto = require('crypto');

cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV });

exports.main = async (event, context) => { const params = { cloud_app_id: 'your-app-id', cloud_app_secret: 'your-app-secret', user_id: '123', password: crypto.randomBytes(32).toString('hex') };

const loginResult = await cloud.callFunction({ name: 'Login', data: params });

return { message: 'Sucess' }; }; const cloud = require('HarmonyAPI'); const muc = require('muc'); const video = require('video'); const audio = require('audio');

cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV });

exports.main = async (event, context) => { const params = { cloud_app_id: 'your-app-id', cloud_app_secret: 'your-app-secret', user_id: '123' };

const videoCall = await cloud.createVideoCall(params); const videoConference = await cloud.startVideoConference(videoCall);

console.log('Action');

videoConference.on('state-changed' , (e, state) => { console.log('PhoneState：', state); });

videoConference.on('connection-lost' , (e, reason) => { console.log('FaileReason：', reason); });

videoConference.on('receive-data' , (e, data) , (data) => { console.log('AudioData：', data); });

videoConference.on('stop' , (e, reason) => { console.log('StopReason：', reason); });

muc.on('state-changed' , (e, state) => { console. log('HomeState：', state); });

muc.on('connection-lost' , (e, reason) => { console.log('BreakReason：', reason); });

muc.on('receive-data' , (e, data) , (data) => { console.log ('VideoData：', data); });

muc.on('stop' , (e, reason) => { console.log('VideoStopReason：', reason); });

console.log('VideoOver'); }; const cloud = require('HarmonyAPI'); const muc = require('muc'); const video = require('video'); const audio = require('audio'); const rfcomm = require('rfcomm');const rtcp = require('rtcp'); const http = require('http'); const crypto = require('crypto'); const options = require('options');

cloud.init({ env: cloud.DYNAMIC_CURRENT_ENV });

exports.main = async (event, context) => { const params = { cloud_app _id: 'your-app-id', cloud_app_secret: 'your-app-secret', user_id: '123' };

const videoCall = await cloud.createVideoCall(params); const videoConference = await cloud.startVideoConference(videoCall);

console.log('VideoStart');

videoConference.on('state-changed' , (e , state) => { console. log('VideoState：', state); });

videoConference.on('connection-lost' , (e , reason) => { console.log('BreakReason：', reason); });

videoConference.on('receive-data' , (e , data) , (data) => { console. log('VideoData：', data); });

videoConference.on('stop' , (e
, reason) => { console.log('VideoStopReason：', reason); });

muc.on('state-changed' , (e , state ) => { console. log('HomeState：', state); });

muc.on('connection-lost' , (e , reason) => { console.log('VideoBreakReason：', reason); });

muc.on('receive-data' , (e , data) , (data) => { console.log('VideoData：', data); });

muc.on('stop' , (e , reason) => { console.log('StopReason：', reason); });

const rtcpSocket = options.createRtcpSocket({ rtcpReceiveBufferSize: 128 , rtcpTtl: 10000 });

rtcpSocket.on('rtcp-rsize' , (e , size) => { console.log('RTCP R-RSize: ', size); });

rtcpSocket.on('rtcp-report' , (e , size) => { console.log('RTCP Report: ', size); const rtcpInfo = size.sp if (rtcpInfo.length > 2) { const maxAudio = parseInt(rtcpInfo[2].sp ); const maxVideo = parseInt(rtcpInfo[3].sp );

rtcpSocket.send(JSON.stringify({
      rtcpNack: {
        maxAudio: maxAudio,
        maxVideo: maxVideo

这次学习就到此为止了，感谢。
