【中文标题】在 React Js 中实现 Quickblox 视频会议时获取“DTLS 警报”【英文标题】：Getting 'DTLS alert' while implementing Quickblox Video Conferencing in React Js 【发布时间】：2021-04-01 10:20:07 【问题描述】：我正在我的 React 应用程序中实现 Quickblox 视频会议服务 - 但是我已经在我的 react 应用程序中实现了 Quickblox SDK，并且所有 Quickblox 功能都运行良好。在控制台中，我检查了函数的响应，它们也运行良好。每当系统尝试将我的 localMediaStream 附加到流媒体服务器时，它都会给我这个错误：
LOCAL WebRTC PeerConnection is down now (reason: DTLS alert) (userId: null)
我认为这可能是 SSL 的问题，因为它部署在我的本地 MacOS 机器上，所以我将它部署在启用 SSL 的 Live Server 上，但错误仍然相同。这是我正在使用的代码：
import React from 'react';
import observer from 'mobx-react';
import endcall from '../../../assets/images/endcall.svg';
import './styles.scss';
import adapter from 'webrtc-adapter';
const QBVideoConferencingClient = require('quickblox/quickblox-multiparty-video-conferencing-client-0.8.6.min.js');
@observer class VideoConferencing extends React.Component
componentDidMount()
const config =
server: "wss://-----.quickblox.com:8989", // Hiding on ***
//debug: true, // optional
//iceServers: [], // optional
;
//const QB = new QuickBlox();
const client = new QBVideoConferencingClient(config);
client
.createSession()
.then(() =>
// session created
const isRemote = false;
const userId = null;
client
.attachVideoConferencingPlugin(isRemote, userId)
.then((plugin) =>
const eventHandler = console.log; // use your own event handler(s)
Object.keys(plugin.events).forEach((key) =>
plugin.on(plugin.events[key], eventHandler)
);
plugin.addListener(plugin.events.CONSENT_DIALOG, this.consentDialog);
plugin.addListener(plugin.events.MEDIA_STATE, this.mediaState);
plugin.addListener(plugin.events.WEBRTC_STATE, this.webrtcState);
plugin.addListener(plugin.events.SLOW_LINK, this.slowLink);
plugin.addListener(plugin.events.ICE_STATE, this.iceState);
plugin.addListener(plugin.events.DETACHED, this.detached);
plugin.addListener(plugin.events.CLEANUP, this.cleanup);
const joinParams =
roomId: "room_12311",
userId: parseInt(this.props.match.params.id),
// display: "Tarun Narula",
// onlyAudio: false,
// role: "publisher",
// video: "fhdres",
;
client
.join(joinParams)
.then(() =>
// joined successfully
client
.listOnlineParticipants('room_123')
.then((participants) =>
// handle as necessary
console.log('Participants List');
console.log(participants);
)
.catch((error) =>
// handle error
);
client.on(client.events.PARTICIPANT_JOINED, (userId, userDisplayName) =>
//alert('Participant Joined ' + userId + ' -- '+userDisplayName);
);
client.on(client.events.PARTICIPANT_LEFT, (userId, userDisplayName) =>
//alert('Participant Left ' + userId + ' -- '+userDisplayName);
);
client.on(client.events.LOCAL_STREAM, (stream) =>
const localVideo = document.querySelector("video#curUserVidElem");
QBVideoConferencingClient.attachMediaStream(localVideo, stream);
);
client.on(client.events.REMOTE_STREAM, (stream, userId) =>
const remoteVideo = document.querySelector("video#frontVideoElem");
QBVideoConferencingClient.attachMediaStream(remoteVideo, stream);
);
client.on(client.events.SESSION_DESTROYED, () =>
//alert('Session Destroyed');
);
client.on(client.events.ERROR, (error) =>
// handle error
console.log('error');
console.log(error);
console.log('error');
);
)
.catch((error) =>
// handle error
);
)
.catch((error) =>
// some error occurred
);
)
.catch((error) =>
// some error occurred

解决步骤：
验证我的本地计算机的防火墙已禁用 已验证任何 html 块都没有阻挡摄像头空间 已将最终版本上传到启用 SSL 的 Live 服务器，但仍然存在错误进行了数小时的研究，但找不到任何关于此的信息。任何帮助将不胜感激。
提前致谢。
【问题讨论】：
【参考方案1】：这个问题很可能与测试服务器问题有关，因为它对我来说在专用服务器上运行良好。
据我所知，他们无法保证测试服务器连接的稳定性（这是我们团队使用专用服务器的主要原因）。
