RE: RPG sockets HTTPS subfolder

Scott,

Thank you for directing me to that!

I knew <test> wasn't an HTTP operation, I was just trying to see if I could connect to a server and send something (anything) and see if it gets there. I wasn't aware it HAD to be an operation...
I was conceptually seeing the actual data I send (to use the telephone analogy in the article I read) as the "talking" part
and on the phone you can "say" anything... I thought I could "send" nonsense if I wanted, just to test the ability to send, but obviously in this case it has to be a real language the server will understand, as I now know.

The project I'm getting started on actually wants XML sent to an HTTPS server. (and returns XML)
I'm now just trying to prove that it's physically possible to send to an HTTPS server.
Now I know I need a different tool, not the socket APIs, but the GSKit APIs.

I was envisioning using sockets for the communications and (also from another article you wrote!) the XML_INTO and CGIDEV2 to receive/create the actual XML.

I imagine I'll use the GSKit API (or HTTPAPI?) for the communications, and XML_INTO / CGIDEV2 for the XML creation & extraction. At least I now know the direction I have to move.

Thanks again,
Charlie

Hi Charlie,

If you are truly connecting to an HTTPS server (as you say) then you need to be using SSL/TLS. The normal socket APIs aren't going to do the job, you need to call APIs capable of SSL. I recommend the GSKit API.

If you are actually connecting to an HTTP server (as opposed to HTTPS) which would make more sense, then ignore the preceding paragraph :)

At any rate, <test> isn't a valid HTTP operation.

Hi,

I'm Charlie, I'm an RPG programmer in New Jersey, working on my first project involving sockets--actually have two similar projects that will involve socket communications. No one at my company works with sockets.

I'm very new with sockets--I just started, so please bear with me.

I've read several articles by Scott Klement, downloaded the SOCKET_H file and started writing my first program, trying to communicate with an https server. For now, just for testing, I'm writing to one of our own Beta https website.

I set up the Host Table entry with the IP address of our beta website,
and in my RPG program, I have my gethostbyname( ), getservbyname( ),
socket ( ), a connect( ) and I'm using the SendAscii prototype that combines QDCXLATE and send ( ).

For now, just to quick-test my connection, I'm just sending a little text message ("<test>") to the server.

From debugging the program, I seem to be getting a connection (I'm not coming back with -1).

The web programmer says that he sees I'm getting a connection and asked that I send my message to a specific folder within the main site.

So, where I'm currently connecting to beta.xxxxx.com he wants me to
send to beta.xxxx.com/sub1/sub2

I can't find in any of the sockets documentation how to specify the sub1/sub2 part of the URL.

I thought perhaps the entire URL has to be part of the Host Table Entry, but it didn't like it.

Where do I define the URL with the "sub1/sub2" and tell it to send my data there?

Thanks,
Charlie

Here's some of my code:

p_hostent = gethostbyname(@Host);
if (p_hostent = *NULL);
.
.
. (Error handling Code)
else;
addr = h_addr;
endif;

(This seems to work)

p_servent = getservbyname(@Serv: @Prot); if (p_servent<> *NULL);
port = s_port;
else;
port = tcdfpt;
endif;

(This is getting the correct port)

s = socket(@AFam: @STyp: @PFam);
If (s = -1);
.
.
. (Error handling code)
endif;

(This seems to work... Address family is 2, Socket Type is 1, Protocal
Family is 6)

Then I do this...

connto = *ALLx'00';
connto.sin_family = @AFam;
connto.sin_addr = addr;
connto.sin_port = port;

// If error in connect.

if connect(s: %addr(connto): %size(connto)) = -1;

(error code)


Endif;


Then I do this...

SendAscii(s: '<test>');
Using '<test>' as my test message just to see if it worked.
