小弟是一个新手，刚接触nodeJS不久，我现在遇到一个问题搞了半天自己无法解决，哪位大神能指点一下小弟将不胜感激。
我用nodejs做无服务器，用socket.io接收客户端的连接，客户端是java程序写的：
客户端如下：
import java.io.*;
import java.net.*;
public class TalkClient {
public static void main(String args[]) throws Exception {
String host = "127.0.0.1";
int port = 3000;
Socket client = new Socket(host, port);
Writer writer = new OutputStreamWriter(client.getOutputStream());
writer.write("Hello Server.");
writer.flush();
Reader reader = new InputStreamReader(client.getInputStream());
char chars[] = new char[64];
int len;
StringBuffer sb = new StringBuffer();
while ((len=reader.read(chars)) != -1) {
sb.append(new String(chars, 0, len));
}
System.out.println("from server: " + sb);
writer.close();
reader.close();
client.close();
}
}
服务器端如下：
//引入程序包
var express = require('express')
, path = require('path')
, app = express()
, server = require('http').createServer(app)
, io = require('socket.io').listen(server);
io.sockets.on('connection', function(socket){
console.log("有连接来了");
});
//express基本配置
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
});
app.configure('development', function(){
app.use(express.errorHandler());
});
server.listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
当我运行客户端java程序的时候，服务器端不是应该打印一行“有链接来了”么？
可是怎么实验也没有啊，问题出在哪里啊？求教，急！
