Need Help with HTTP_POST FM

Former Member — Thu, 08 May 2014 05:08:27 GMT

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

Anoop

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.

Cheers,

Custodio

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

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>");
}
}

On SAP:

Using program RSHTTP20

Hi Eitan,

Thank you very much.I solved the issue by passing the BLANKSTOCRLF value as 'X'.
