腾讯云获取进入房间人数

const TRTC = require('trtc-js-sdk');

const client = TRTC.createClient({
  mode: 'rtc',
  sdkAppId: YOUR_SDK_APP_ID,
  userId: 'user_id',
  userSig: 'user_sig'
});

client.join({ roomId: YOUR_ROOM_ID }).then(() => {
  console.log('User has joined the room');
}).catch(error => {
  console.error('Failed to join the room', error);
});

client.on('onUserEnter', (event) => {
  console.log('User entered:', event.userId);
  updateRoomUserCount(event.userId, true);
});

client.on('onUserExit', (event) => {
  console.log('User exited:', event.userId);
  updateRoomUserCount(event.userId, false);
});

function updateRoomUserCount(userId, isEntering) {
  // 这里可以实现具体的房间人数更新逻辑
  if (isEntering) {
    // 用户进入房间，增加计数
    roomUserCount++;
  } else {
    // 用户离开房间，减少计数
    roomUserCount--;
  }
  console.log('Current room user count:', roomUserCount);
}

let roomUserCount = 0;

// 初始化时，可以通过API获取当前房间的用户列表来设置初始值
client.getUsers().then(users => {
  roomUserCount = users.length;
  console.log('Initial room user count:', roomUserCount);
}).catch(error => {
  console.error('Failed to get users', error);
});
