我写了一个客户端和服务端,当开启服务端后,开启客户端输入数据,服务器端收不到。import java.io.*;
import java.net.*;
class UdpSend
{
public static void main(String[] args) throws Exception
{
DatagramSocket ds = new DatagramSocket(); BufferedReader bufr =
new BufferedReader(new InputStreamReader(System.in)); String line = null; while((line=bufr.readLine())!=null)
{
byte[] buf = line.getBytes(); DatagramPacket dp = new DatagramPacket(buf,buf.length,InetAddress.getByName("192.168.6.70"),10004); ds.send(dp); } ds.close();
}
}
class UdpRece
{
public static void main(String[] args) throws Exception
{
DatagramSocket ds = new DatagramSocket(10004); while(true)
{ byte[] buf = new byte[1024];
DatagramPacket dp = new DatagramPacket(buf,buf.length); ds.receive(dp); String ip = dp.getAddress().getHostAddress(); String data = new String(dp.getData(),0,dp.getLength()); System.out.println(ip+"::"+data);
} }}
我的ip地址是192.168.6.70,前一阵子是可以用的,后来我改过一次ip,然后做表单提交的时候,
要提交到本地,然后把ip改回了192.168.6.70,<form action="http://192.168.6.70:10009">
写了个本地的服务端,端口10009打印一段字符串,然后也是连接不上,不知道怎么回事,是不是ip
设置问题?还是我改了什么地方了?

给个例子。
