Re: HTTP API - EXAMPLE8 - HTTP/1.1 500 Internal Server Error
Thanks all and Scott. The code Scott given worked perfectly.

Hello,
Most likely, you are misformatting the data you're sending. That's
the
cause of 99% of the '500' errors. Since we haven't seen it, or a
debug
log, or even the response message from the server (if there is one)
it's
really hard for us to help you.
Understand this: Every web service is different. Just because you
think
you know what to send, doesn't me that *we* do, or that we know
what
you're doing wrong.
The curl example is helpful. It gives us a lot more information
than we
had before -- but it doesn't tell us what you *are* doing, it only
tells
us what you SHOULD BE doing.
The curl example was obviously written for a Unix shell script. The
syntax used in Unix is much, much, different from the same syntax
in RPG.
You say you're using EXAMPLE8 -- that's an example that I've
scheduled
to be removed from HTTPAPI because it's no longer needed (there are
easier ways to POST a file than dumping it to a user space these
days..
the user space technique is from a very old version of HTTPAPI.
Though,
it does still work.)
But, your curl example doesn't send a file! It sends a string. So
it's
really not all that similar, is it? And since the curl example is
in
Unix shell script syntax, you'd have to understand how to format
your
file correctly, removing the characters that would normally be
handled
by the shell. How can we possibly tell if you did that correctly?
Mind
reading?
If I were trying to do the same thing in RPG with HTTPAPI, I'd
probably
end up with something like this:
D data s 1000a varying
D rc s 10i 0
D tempfile s 50a varying
/free
data =
'{ +
''event_type'':''trigger'', +
''description'':''Server www15 running low on memory'',
+
''service_key'':''e93facc04764012d7bfb002500d5d1a6'', +
''incident_key'':''frontend-low-free-memory'', +
''payload'' : { +
''server_name'': ''www15'',+
''memory_usage'': ''98%'',+
''threshold'': 90 +
} +
}';
http_setCCSIDs(1208: 0);
tempfile = http_tempfile();
rc = http_url_post( '[2]https://events.pagerduty.com/+
generic/2010-04-15/create_event.json'
: %addr(data) + 2
: %len(data)
: tempfile
: HTTP_TIMEOUT
: HTTP_USERAGENT
: 'application/json' );
if (rc <> 1);
http_crash();
endif;
But, bear in mind that there are potential CCSID problems with the
{}
characters... it might be a good idea to use Unicode instead of
EBCDIC
for those characters.
