HTTP post from ABAP using Object Oriented method

Former Member — Thu, 07 May 2009 19:26:54 GMT

Hi ,

I want to call HTTP from ABAP. I came to know that using classes & objects is the best way to fulfill it.

Interface:

xml_document type ref to cl_xml_document

method post_xml_document.

data: client type ref to if_http_client,

xml_response type ref to cl_xml_document.

data: xml_string type string,

xml_xstring type xstring.

data: zsubrc type sy-subrc.

cl_http_client=>create_by_url( exporting url = 'http://www.example.com/post-url.xml' importing client = client exceptions others = 1 ).

client->request->set_header_field( exporting name = '~request_method' value = 'POST' ).

client->request->set_header_field( exporting name = '~server_protocol' value = 'HTTP/1.1' ).

client->request->set_header_field( exporting name = 'Content-Type' value = 'text/xml' ).

xml_document->render_2_string( exporting pretty_print = 'X' importing stream = xml_string ).

client->request->set_cdata( exporting data = xml_string offset = 0 ).

client->authenticate( exporting proxy_authentication = space username = 'username' password = 'password' ).

client->send( exceptions http_communication_failure = 1 http_invalid_state = 2 ).

client->receive( exceptions http_communication_failure = 1 http_invalid_state = 2 http_processing_failed = 3 ).

xml_xstring = client->response->get_data( ).

zsubrc = xml_response->parse_xstring( stream = xml_xstring ).

endmethod.

Above code can be used to do my work.

Apart from the code in ABAP, what are the configurational setting that we need to do ?

Thanks,

Shivaa..

Thats nonsense, create_by_url does not need an rfc connection. TA SICF is correct.
