Java how to respond to HttpExchange [duplicate]

Isabella Campbell |

I am new to Java. I used write server in Golang. I need to send response to the HttpExchange. Here is my code:

public static void main(String[] args) throws IOException
{ Server = HttpServer.create(new InetSocketAddress(8000),0); Server.createContext("/login", new SimpleHandler()); Server.setExecutor(null); Server.start();
}
class SimpleHandler implements HttpHandler
{ @Override public void handle(HttpExchange request) throws IOException { //Here I need to do like request.Response.Write(200,"DONE"); }
}

Handle method in your case should looks like: 

 public void handle(HttpExchange request) throws IOException { byte[] response = "DONE".getBytes(); e.sendResponseHeaders(200, response.length); OutputStream os = e.getResponseBody(); os.write(response); os.close(); }

Use the sendResponseHeaders(int rCode, long responseLength) method. See the documentation and the example:

@Override
public void handle(HttpExchange request) throws IOException { request.sendResponseHeaders(200, "DONE");
}
