I asked a similar question in another thread but I think I'm just having trouble getting the syntax right at this point. I basically want to open a socket in Java, send a HTTP request message to get the header fields of a specific web page. My program looks like this so far:
String server = "www.w3.org";
int port = 80;
String uri = "/Protocols/rfc2616/rfc2616-sec5.html#sec5.1"
Socket socket = new Socket(server, port);
PrintStream output = new PrintStream(socket.getOutputStream());
BufferedReader socketInput = new BufferedReader(new InputStreamReader(socket.getInputStream()));
output.println("HEAD " + uri + " HTTP/1.1");
//String response = "";
String line = "";
while((line = socketInput.readLine()) != null){
System.out.println(line);
}
socketInput.close();
socket.close();
It doesn't really work. Or it doesn't work for all websites. If someone could just tell me the immediate problems with what I'm doing, that would be great. Thank you!
