I'm trying to write a simple HTTP Client & Server using the new (JDK 11) HttpClient.
JDK.: OpenJDK 17.0.0
The Client is connecting to the Server but doesn't seem to be POST'ing any data.
After the Server receives the incoming Connection, it tries to read the data.
The read never ends.
Does anyone know what I'm doing wrong?
Server Source:
package de.ipp.client.server;
import java.io.*;
import java.net.*;
import java.time.ZonedDateTime;
public class IppServer {
public static final int PORT = 31613;
public static void main(String[] args) throws IOException {
System .out.println(ZonedDateTime.now() + " IppServer Start.....");
try(final ServerSocket serverSocket = new ServerSocket(PORT))
{
System.out.println(ZonedDateTime.now() + " IppServer Running..: " + serverSocket);
while (true) {
final Thread thread = new Thread(getSocketRunnable(serverSocket.accept()));
; thread.setDaemon(true);
; thread.start();
}
}
}
private static Runnable getSocketRunnable(final Socket socket) {
return () -> {
System .out.println(ZonedDateTime.now() + " IppServer Socket...: incoming -> " + socket);
try(final InputStream ist = socket.getInputStream())
{
System.out.println(ZonedDateTime.now() + " IppServer Reading...");
final byte[] bytes = ist.readAllBytes();
System.out.println(ZonedDateTime.now() + " IppServer L'Bytes..: " + bytes.length);
}
catch (final IOException e) {
System.out.println(ZonedDateTime.now() + " IppServer Error!!..: " + e.getMessage());
}
};
}
}
Client Source:
package de.ipp.client.server;
import java.net.URI;
import java.net.http.*;
import java.net.http.HttpClient.Version;
import java.net.http.HttpRequest.*;
import java.net.http.HttpResponse.BodyHandlers;
import java.time.ZonedDateTime;
public class IppClient {
public static void main(final String[] args) throws Exception {
final URI uri = new URI("http://localhost:" + IppServer.PORT + "/printers");
final BodyPublisher publisher = HttpRequest.BodyPublishers.ofByteArray("SomeBytes".getBytes());
final Builder builder = HttpRequest.newBuilder();
; builder.uri (uri);
; builder.version (Version.HTTP_1_1);
; builder.setHeader("Transfer-Encoding", "chunked");
; builder.setHeader("Content-Type", "application/ipp");
; builder.setHeader("Accept-Encoding", "gzip,deflate");
; builder.POST(publisher);
final HttpRequest request = builder.build();
System.out.println(ZonedDateTime.now() + " IppClient Posting..: " + uri);
final HttpResponse<byte[]> response = HttpClient.newHttpClient().send(request, BodyHandlers.ofByteArray());
System.out.println(ZonedDateTime.now() + " IppClient Response.: " + response.statusCode());
}
}
