socke常也称作"套接字"，用于描述IP地址和端口，是一个通信链的句柄。应用通常通过"套接字"向网络发出请求或者应答网络请求。
编写socke的服务器端代码：
package com.evan.blog;
import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class BlogServer {
public static void main(String[] args) {
try {
ServerSocket serverSocket = new ServerSocket(8080);
Socket socket = serverSocket.accept();
InputStream is = socket.getInputStream();
byte[] b = new byte[1024];
int len;
StringBuffer sb = new StringBuffer();
while ((len = is.read(b)) != -1) {
String str = new String(b, 0, len);
sb.append(str);
}
is.close();
System.out.println(sb.toString());
System.out.println("有人访问本机的8080端口了，并传入了‘" + sb.toString() + "‘值");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
客户端源码：
package com.evan.blog;
import java.io.IOException;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
public class BlogClient {
public static void main(String[] args) {
try {
Socket socket = new Socket(InetAddress.getLocalHost()
.getHostAddress(), 8080);//得到本机的IP地址
OutputStream os = socket.getOutputStream();
String str = "my blog socket";
os.write(str.getBytes());
os.flush();
os.close();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
