腾讯云音视频解决方案采用IM信令控制层
+TRTC媒体传输层
的双架构设计,实现核心能力解耦:
# 安装核心依赖
npm install tim-js-sdk trtc-js-sdk --save
# 小程序平台需额外安装
npm install miniprogram-api-typings --save-dev
// utils/trtc-manager.js
import TRTC from 'trtc-js-sdk';
import TIM from 'tim-js-sdk';
// TRTC客户端配置
export const createTRTCClient = (userId, userSig) => {
return TRTC.createClient({
mode: 'rtc',
sdkAppId: xxxxxxxx,
userId,
userSig,
// 高级音频配置
audio: {
autoGainControl: true,
noiseSuppression: true
}
});
};
// IM客户端配置
export const createIMClient = () => {
const tim = TIM.create({
SDKAppID: xxxxxxxx
});
// 添加日志拦截器
tim.on(TIM.EVENT.ERROR, (err) => {
console.error('IM错误:', err);
// 添加自定义错误处理逻辑
});
return tim;
};
// 呼叫管理类
class CallManager {
constructor() {
this.currentCall = null;
this.roomId = this.generateRoomID();
}
generateRoomID() {
return Math.floor(Math.random() * 1000000);
}
async initiateCall(targetUser) {
try {
// 1. 加入TRTC房间
await this.trtcClient.join({ roomId: this.roomId });
// 2. 发送IM信令
const customMessage = tim.createCustomMessage({
to: targetUser,
conversationType: 'C2C',
payload: {
data: JSON.stringify({
type: 'TRTC_CALL',
roomId: this.roomId,
sdkAppId: xxxxxxxx,
caller: tim.getUserID()
})
}
});
await tim.sendMessage(customMessage);
this.currentCall = { state: 'calling', target: targetUser };
} catch (err) {
this.handleError('CALL_INITIATE_FAILED', err);
}
}
async acceptCall(inviteData) {
try {
// 1. 加入TRTC房间
await this.trtcClient.join({
roomId: inviteData.roomId,
userId: tim.getUserID(),
userSig: await this.generateUserSig()
});
// 2. 发送接受应答
const ackMsg = tim.createCustomMessage({
to: inviteData.caller,
conversationType: 'C2C',
payload: {
data: JSON.stringify({ type: 'TRTC_ACCEPT' })
}
});
await tim.sendMessage(ackMsg);
this.currentCall = { state: 'connected', roomId: inviteData.roomId };

// 动态调整视频编码参数

if (!granted.cameraGranted || !granted.audioGranted) {
uni.showModal({
title: '权限申请失败',

#endif
}
UserSig生成规范:
房间号安全:
// 房间号生成策略
function generateSecureRoomID() {
const timestamp = Date.now();
const random = Math.floor(Math.random() * 1000);
return Buffer.from(`${timestamp}-${random}`).toString('base64');
}
敏感信息过滤:
// 信令内容校验
function validateSignalData(data) {
const allowedKeys = ['type', 'roomId', 'sdkAppId', 'caller'];
const invalidKeys = Object.keys(data).filter(key => !allowedKeys.includes(key));
if (invalidKeys.length > 0) {
throw new Error('Invalid signal data');
}
}
