Manual HTTPS POST from ABAP

[Former Member]

I'm trying to use a web service implementation that doesn't come with a WSDL file - so, no generated proxy for me to use. It also needs me to send an XML file via an HTTP POST - not in a SOAP envelope.

Does anyone know of a way of manually posting something via HTTP in ABAP? I'm sure there must be some function module or class that exposes that functionality - I just can't find it! Any ideas anyone?

I have noticed a similar kind of post on SDN, the only difference in this case is the URL is HTTPS one. The vendor webservice works in two steps;

1. Login to the HTTPS service via login url(https://.../login.aspx), using uid and pwd.

2. Call the actual url(https://.../webservice/webser1.aspx) using which the xml data needs to be transmitted.

I have a sample code(C#), which works this way. Not sure how do we get this done in ABAP.

The following code is ABAP for a direct HTTP Post (not tested) I think. Also try looking at function module HTTP2_POST and programs that use it.

 REPORT Z_HTTP_POST .

parameters : p_uri(100) lower case.

data:  g_status_code(5),
       g_status_text(300),
       g_len type i.

data:  gt_request_header  type table of sbcheader with header line,
       gt_request_body    type table of sbcbody with header line,
       gt_response_header type table of sbcheader with header line,
       gt_response_body   type table of sbcbody with header line .
