Node.js打印输入字母

Question

我试着用node.js构建一个聊天服务器，但是它把输入逐个字母地打印在其他客户端的控制台上，有没有办法把它们放在一起？

var net = require('net')

var chatServer= net.createServer()
clientList = []

chatServer.on('connection', function(client){
client.name = client.remoteAddress + ":" + client.remotePort
client.write('Hi' + client.name + "!\n");

clientList.push(client)

client.on('data', function(data){
    broadcast(data, client)
})
})

function broadcast(message, client){
for(var i=0; i<clientList.length;i+=1){
    if(client !== clientList[i]){
        clientList[i].write(client.name + " says" + message +"\n")
    }
}
}

chatServer.listen(9000, "127.0.0.1")

谢谢。

如果您的消息是换行符分隔的，您可以这样做：

chatServer.on('connection', function(client) {
  client.name = client.remoteAddress + ":" + client.remotePort;
  client.write('Hi' + client.name + "!\n");

  clientList.push(client)

  var buf = '';
  client.setEncoding('utf8');
  client.on('data', function(data) {
    buf += data;
    var i;
    while ((i = buf.indexOf('\n')) > -1) {
      broadcast(buf.substring(0, i), client);
      buf = buf.substring(i + 1);
    }
  });
});
