RE: REST from V7R3 -- MIDRANGE-L

Don,

First, if you do not find the file

/qibm/proddata/os/WebServices/V1/client/include/axis/ITransport.h

you should load the latest HTTP group (even if you do have it you should
load latest HTTP group to pick up fixes).

The file has the prototypes for the transport APIs.

When I include a file, I do something like:

#include <axis/Axis.h>
#include <axis/ITransport.h>
#include <axis/AxisException.h>

and when I compile, I do something like:

CRTCMOD MODULE(AMRA/RESTCS) SRCSTMF('/restcs.c') DBGVIEW(*ALL) ENUM(*INT)
INCDIR('/qibm/proddata/os/webservices/v1/client/include')

CRTpgm pgm(AMRA/RESTCS) module(amra/restcs) bndsrvpgm(qsysdir/qaxis10cc)
ACTGRP(*NEW)

There is sample C source (restCS.c) at:

https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/dW%20IBM%20Integrated%20Web%20Services%20for%20i/page/Send%20user-defined%20payloads%20using%20new%20client%20APIs

Documentation may be found in the Web Service Client for ILE Programming
GUI on the web site[1] near bottom of page, starting on page 169.

Is there anything that would keep a V7R1 system (DEV box and PRD is
V7R3) would not support this line? I tried both with "" and <>.

#include "/QIBM/ProdData/OS/WebServices/V1/client/include/axis/Axis.h"

I get the following

Message . . . . : DPOLIB/QCSRC(SOMCLEPCCS), 52.11: CZM0296(30)
#include file
"/QIBM/ProdData/OS/WebServices/V1/client/include/axis/Axis.h" not
found.

The #include for these and others

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <sys/types.h>

Work just fine.

Hi, you are the client, so you do not need an integrated web
services server or any other server.

To consume a service, I would take a look at the integrated web
services client for ILE[1] - in particular, the transport APIs
(article for RPG[2]). Most examples are from the RPG perspective,
but you can extrapolate to do within C code since it is the same
APIs that are used by both C and RPG. The benefit of using
transport APIs is that it handles TCP/IP and HTTP and SSL for you.

If this needs to go to another group please let me know. First a
little history, back in the day (2005) I had to write a PGM on the
i5 to send credit card requests to Vital (now known as TSYS) and that
has worked for years. All in C using a socket connection and the
gsk_. I learned a lot and pretty sure Scott K had some examples.

So now the powers to be want to move to Sage (known now as paya).
This is a POST/GET type process. Found an example of RPG (sorry now
in my skill set) but I need to do this in C or CBL (ILE). Maybe even
PHP (another one not in my skill set). So some of the documentation
indicated I need to setup Web Services Server. Is this correct? The
PGM will need to submit POST and GET to the URL
provided by "paya". Am I even close?
Thanks
