在服务器端为每个WebSocket连接创建一个唯一标识符，并在每条发送的消息中包含此标识符。客户端收到消息后，可以根据标识符将它们分组并正确地显示。以下是Node.js示例代码：

// server side const WebSocket = require('ws'); const wss = new WebSocket.Server({ port: 8080 });

function getUniqueID() { return Date.now().toString(36) + Math.random().toString(36).substr(2); }

wss.on('connection', function connection(ws) { const uniqueID = getUniqueID(); ws.id = uniqueID;

ws.on('message', function incoming(message) { const parsedMsg = JSON.parse(message); const sendMsg = { id: ws.id, content: parsedMsg.content, };

wss.clients.forEach(function each(client) {
  if (client.readyState === WebSocket.OPEN && client.id !== ws.id) {
    client.send(JSON.stringify(sendMsg));
  }
});

}); });

// client side const socket = new WebSocket('ws://localhost:8080');

socket.addEventListener('message', function(event) { const parsedMsg = JSON.parse(event.data); const messageDiv = document.createElement('div'); messageDiv.innerText = parsedMsg.content; document.body.appendChild(messageDiv); });
