// 引入
import TRTC from 'trtc-js-sdk';
// 设置日志输入级别
TRTC.Logger.setLogLevel(TRTC.Logger.LogLevel.WARN);
步骤1:创建 Client 对象
通过 TRTC.createClient() 方法创建 Client 对象,参数设置如下:
- mode: 实时音视频通话模式,设置为videoCall
- sdkAppId: 您从腾讯云申请的 sdkAppId
- userId: 用户 ID
- userSig: 用户签名
**userId 可以获取当前登录用户的账号,也可以随机生成字符串,
通过调用后端接口拿到userSig **
// 获取userSig
public async getUserSig (): Promise<void> {
const res: any = await this.$api.xHttp.get(this.$interfaces.video.usersig, {
appid: this.sdkappid,
userid: this.form.userId
}, null, {defEx: false, defData: false});
if (res.code === 1) {
this.userSig = res.data;
}
}
-房间ID根据后台返回 加入同一个房间 也可以自己定义房间号-
退出视频要调用一下方法, 彻底关闭本地视频流 否则浏览器会一直提示视频还在调用中
this.localStream.close(); // 彻底关闭本地视频流
代码如下:
public mounted () {
this.initTRTC();
}
/***
* 初始化视频
*/
public initTRTC () {
this.clientTRTC = TRTC.createClient({
mode: 'videoCall',
sdkAppId: this.sdkappid, // 此处填写你的sdkappid
userId: this.userId,
userSig: this.userSig
});
this.onStreamAdded(); // 监听远端流事件
this.onStreamSubscribed(); // 订阅远端流
this.onStreamRemoved(); // 取消订阅远端流
this.clientJoin();
}
// 监听远端流事件
public onStreamAdded () {
this.clientTRTC.on('stream-added', (event: any) => {
const remoteStream = event.stream;
console.log('远端流增加: ' + remoteStream.getId());
// 订阅远端流
this.clientTRTC.subscribe(remoteStream);
});
}
// 订阅远端流
public onStreamSubscribed () {
this.clientTRTC.on('stream-subscribed', (event: any) => {
const remoteStream = event.stream;
const remoteId = 'remote' + remoteStream.getId();
console.log('远端流订阅成功:' + remoteStream.getId());
// 播放远端流
// remoteStream.play('remoteVideo-' + remoteStream.getId());
const videoDiv: any = document.createElement('div');
videoDiv.id = remoteId;
videoDiv.style.width = '320px';
videoDiv.style.height = '240px';
videoDiv.style.marginRight = '20px';
videoDiv.style.marginBottom = '20px';
videoDiv.className = 'remoteVidwo';
(document.getElementById('remote-video-wrap') as any).appendChild(videoDiv);
remoteStream.play(remoteId);
});
}
// 加入房间
public clientJoin () {
this.clientTRTC.join({roomId: this.roomId})
.catch((error: any) => {
console.error('进房失败 ' + error);
})
.then(() => {
console.log('进房成功');
// 创建本地流
this.localStream = TRTC.createStream({userId: this.userId, audio: true, video: true});
// 初始化本地流成功
this.createStream();
this.enterRoomInfo(); // 告诉后台执行混流
});
}
// 初始化本地流成功
public createStream () {
this.localStream
.initialize()
.catch((error: any) => {
console.error('初始化本地流失败 ' + error);
})
.then(() => {
console.log('初始化本地流成功');
this.localStream.play('localVideo');
// 发布本地流
this.pubLocalStream();
});
}
// 本地流发布
public pubLocalStream () {
this.clientTRTC
.publish(this.localStream)
.catch((error: any) => {
console.error('本地流发布失败 ' + error);
})
.then(() => {
console.log('本地流发布成功');
});
}
// 取消订阅远端流
public onStreamRemoved () {
this.clientTRTC.on('stream-removed', (event: any) => {
const remoteStream = event.stream;
const remoteId = 'remote' + remoteStream.getId();
remoteStream.stop();
(document.getElementById('remote-video-wrap') as any).removeChild(document.getElementById(remoteId));
});
}
// 关闭视频
public quitRTC () {
this.localStream.close(); // 彻底关闭本地视频流
// 退房
this.clientTRTC.leave().then((res: any) => {
console.log('退房成功', res);
this.$emit('close');
this.leaveRoomInfo(); // 告诉后台执行混流
}).catch((error: any) => {
// 错误不可恢复,需要刷新页面。
console.error('退房失败 ' + error);
});
}
