Need Help with HTTP_POST FM

[Former Member]

Hi Experts,

I have a requirement in which I have to send the xml data to a servlet from my ABAP program.I found that this can be achieved using HTTP_POST FM.I created a sample servlet and tried the FM.When I debugged the program the RESPONSE BODY is filled with characters similar to Chinese. (Please find the attachment).I guess I made some mistake while providing the import parameters to the FM.So it will be really helpful if someone provide a perfect example/instruction to use the FM properly.

Regards

Hi Anoop,

If you believe you made a mistake on the import parameters, it would be helpful you you could share the code with us.

Hi Custodio,

Thank you for the quick response.Please find the piece of code I have written below.

CONSTANTS: v_uri(100) VALUE 'http://xxx.xxx.x.xx:8080/WorkManager/LoginAuth'.

DATA: v_data(20) TYPE c VALUE 'Test String'.

APPEND v_data TO t_request_body.

v_len = strlen( v_data ).

APPEND 'UserAuth=testauth' TO t_request_header.

DATA: status_code(5),

status_text(300).

CALL FUNCTION 'HTTP_POST'

   EXPORTING

     absolute_uri                = v_uri

     request_entity_body_length  = v_len

*   RFC_DESTINATION             =

*   PROXY                       =

*   PROXY_USER                  =

*   PROXY_PASSWORD              =

*   USER                        =

*   PASSWORD                    =

*   BLANKSTOCRLF                =

   IMPORTING

     status_code                 = status_code

     status_text                 = status_text

*   RESPONSE_ENTITY_BODY_LENGTH =

   TABLES

     request_entity_body         = t_request_body

     response_entity_body        = t_response_body

     response_headers            = t_response_header

     request_headers             = t_request_header

exceptions

     connect_failed              = 1

     timeout                     = 2

     internal_error              = 3

     tcpip_error                 = 4

     SYSTEM_FAILURE              = 5

     COMMUNICATION_FAILURE       = 6

     OTHERS                      = 7.

IF sy-subrc <> 0.

* Implement suitable error handling here

ENDIF.

Hi,

I just did a small test.

Using program RSHTTP20

The program is using HTTP_GET

I have this Java prgram that use jetty http://www.eclipse.org/jetty/

I ran this using eclipse .

package servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.AbstractHandler;

public class HelloWorld extends AbstractHandler {

public static void main(String[] args) throws Exception {
  final Server server = new Server(80);
  server.setHandler(new HelloWorld());
  server.start();
  server.join();
}

@Override
public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)
   throws IOException, ServletException {
  response.setContentType("text/html;charset=utf-8");
  response.setStatus(HttpServletResponse.SC_OK);
  baseRequest.setHandled(true);
  response.getWriter().println("<h1>Hello World</h1>");
}
}

Hi Eitan,
