Uniapp 是一个跨平台的应用开发框架,可以同时开发小程序、H5、App 等应用。下面是一个基于 Uniapp 平台开发的小程序直播 demo 的示例代码: 首先,在 Uniapp 项目中引入 WebRTC 相关的库,如 webrtc-adapter、webrtc.js 等。 在 pages 目录下创建一个直播页面,如 Live.vue,其中包含一个 video 标签用于显示视频流。 <template> <view> <video id="remoteVideo" :src="remoteStream" autoplay muted></video> </view> </template> <script> export default { data() { return { peerConnection: null, remoteStream: null, socket: null, roomId: null }; }, created() { this.initSocket(); this.initPeerConnection(); this.joinRoom(); }, methods: { initSocket() { this.socket = uni.connectSocket({ url: 'wss://example.com/live/socket' }); this.socket.onOpen(() => { console.log('WebSocket connected'); }); this.socket.onMessage(event => { const message = JSON.parse(event.data); switch (message.type) { case 'offer': this.handleOffer(message.data); break; case 'candidate': this.handleCandidate(message.data); break; case 'close': this.handleClose(); break; } }); this.socket.onClose(() => { console.log('WebSocket disconnected'); }); }, initPeerConnection() { const config = { iceServers: [ { urls: ['stun:example.com:3478'] }, { urls: ['turn:example.com:3478'], username: 'username', credential: 'password' } ] }; this.peerConnection = new RTCPeerConnection(config); this.peerConnection.ontrack = event => { console.log('Remote stream received'); this.remoteStream = URL.createObjectURL(event.streams[0]); }; this.peerConnection.onicecandidate = event => { if (event.candidate) { this.socket.send({ type: 'candidate', data: event.candidate }); } }; }, joinRoom() { this.socket.send({ type: 'join', data: { roomId: this.roomId } }); }, createOffer() { this.peerConnection.createOffer().then(offer => { this.peerConnection.setLocalDescription(offer); this.socket.send({ type: 'offer', data: offer }); }); }, handleOffer(offer) { this.peerConnection.setRemoteDescription(new RTCSessionDescription(offer)); this.peerConnection.createAnswer().then(answer => { this.peerConnection.setLocalDescription(answer); this.socket.send({ type: 'answer', data: answer }); }); }, handleCandidate(candidate) { this.peerConnection.addIceCandidate(new RTCIceCandidate(candidate)); }, handleClose() { console.log('Peer connection closed'); } } }; </script> 在入口页面中添加一个链接到直播页面的按钮,并传递房间号作为参数。 <template> <view class="container"> <button @click="startLive(roomId)">Start Live</button> </view> </template
