node.js实现websocket聊天室

要实现基于Node.js的WebSocket聊天室，可以使用nodejs-websocket和socket.io这两个模块。首先，需要在Node.js环境中安装这两个模块。

使用nodejs-websocket模块的实现示例如下所示：

var ws = require("nodejs-websocket");

var server = ws.createServer(function(conn){
    conn.on("text", function(data){
        // 处理客户端发送的消息
        console.log("Received message from client: " + data);
        // 向所有连接的客户端广播消息
        server.connections.forEach(function(connection){
            connection.sendText(data);
        });
    });

    conn.on("close", function(code, reason){
        // 处理客户端断开连接的事件
        console.log("Client disconnected");
    });
}).listen(8000);

console.log("WebSocket server listening on port 8000");

而使用socket.io模块的实现示例如下所示：

var app = require("http").createServer();
var io = require("socket.io")(app);

io.on("connection", function(socket){
    socket.on("message", function(data){
        // 处理客户端发送的消息
        console.log("Received message from client: " + data);
        // 向<span class="em">1</span><span class="em">2</span><span class="em">3</span>
