What? Super simple HTTP implementation in Java, for building simple backend for websites or web API's. Using Sun Microsystems packages, still works in OpenJDK 14.0.2 (At least tested, should work in newer versions too). Why? Becouse I don't want to install any third party packages, and it's just easier that way.
I have found this code in StackOverflow answer made by user BalusC, so huge thanks for that. However, he says in this answer, that code he posted is straight from Oracle documentation. Code is not mine, all rights belong to its author.
import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
public class Test {
public static void main(String[] args) throws Exception {
HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
server.createContext("/test", new MyHandler());
server.setExecutor(null); // creates a default executor
server.start();
}
static class MyHandler implements HttpHandler {
@Override
public void handle(HttpExchange t) throws IOException {
String response = "This is the response";
t.sendResponseHeaders(200, response.length());
OutputStream os = t.getResponseBody();
os.write(response.getBytes());
os.close();
}
}
}
