Re: Programming to Rest Server

Moved my little java class to the AS/400 and dropped into QSH and ran it and
no problems. Works like a charm so I am left with the fact that there is
something about the HTTPAPI and our REST Sever. I am going to just call the
java class from my RPG service program to do the send. I know now that that
works.

This might be more work than it's worth (or maybe not if this is an
important business need), but you could also Wireshark what is coming from
the IBMi by putting up a simple Java Servlet on your PC and then have
Wireshark monitor the *inbound* data. Then do a compare/contrast on that
data. This will let you know if some funky translation is happening as it
leaves the IBMi.

the request and they all work. The only thing that does not work is

sending

from AS/400 via HTTPAPI. I have put Wireshark on my machine and watched

the

string go out from my pc and the HTTP packets are exactly the same as

what

I
see in the HTTPAPI dump and we know that the server is receiving the

string

fine and decoding it because of what we see in the dump.

The only differences between the data being sent from each source is the
user-agent. The consultant insists that the error is happening because

the

connection is being closed immediately. I am going to try moving the Java
class to my AS/400 and calling that and see if will work.

All in all, bizarre.

Could it be URL encoding? The fact the you can type it in a browser
and it works, tells me one of two things: You are subtly keying in
something that isn't in your code HTTPAPI or there is an encoding issue
that the browser is managing to deal with that your code in HTTPAPI
isn't handling. I think HTTPAPI naturally encodes everything but
perhaps something small is missing. Cut and paste the browser url into
HTTPAPI and test it directly perhaps?

I am using Scott's HTTP Api to attempt to write to a Rest Server.

In all the previous projects that I have done using this api, the

targets

where outside the company servers but this server was created by a
consultant and he tells me that it is a Rest Server.

I am using the HTTP_Url_Get_XML to send the following

http://cre-freitrater:8080/cre_freitrater/rest/freitrater/1

The request chain that is being sent to it looks like the following:

GET /cre_freitrater/rest/freitrater/1 HTTP/1.1 Host:

cre-freitrater:8080

User-Agent: http-api/1.23

I am getting back a 500 response saying that there was an internal

server

error.

I can type the same string (the first string) into the browser and it

runs

without a hitch.

This is probably a Scott question but what has to be done different

for

REST

server than a regular HTTP server?. According to what I have read it

just

uses regular HTTP protocols.

Can anyone point me to an article on writing a Rest Client in RPG?

Any help would be appreciated.
