public class URLSender {

public static void main(String[] args) throws IOException {
try {
Socket socket = new Socket("www.nwu.edu.cn", 80);
boolean autoflush = true;
PrintWriter out = new PrintWriter(socket.getOutputStream(), autoflush);
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//send an HTTP request to the web server
out.println("GET / HTTP/1.1");

boolean loop = true;

socket.close();
} catch (UnknownHostException e) {

2、用Socket发送一个POST请求try {
// Construct data
String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");
// Create a socket to the host
String hostname = "hostname.com";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket socket = new Socket(addr, port);
// Send header
String path = "/servlet/SomeServlet";
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
wr.write("POST "+path+" HTTP/1.0\r\n");
wr.write("Content-Length: "+data.length()+"\r\n");
wr.write("Content-Type: application/x-www-form-urlencoded\r\n");
wr.write("\r\n");
// Send data
wr.write(data);
wr.flush();
// Get response
BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
// Process line...
}
wr.close();
rd.close();
} catch (Exception e) {
