Re: http_url_post_xml and REST -- RPG400-L

How do you have your open function prototyped?

This won't work properly with CCSID 1208, since you are specifying code
pages (which was a limitation of the IFS in V4R5 and earlier, but with
V5R1 CCSID support was added.) Also, I would recommend using
O_TEXT_CREAT and eliminating the "two opens" scenario.. the "two opens"
situation would work fine if you're targeting the root or QOpenSys file
system, but does not work with, for example, /QNTC. Best practice is to
use O_TEXT_CREAT if you are targeting V5R2 or later.

It's also very strange that you are granting execute permission to the
file -- this allows QShell or PASE shells to run your XML document as a
shell script -- which doesn't make any sense at all.

Here's what I would do (requires V5R2 or later):

   flags = O_RDWR + O_CREAT + O_TRUNC + O_TEXTDATA
   + O_CCSID + O_TEXT_CREAT;

   mode = S_IRUSR + S_IWUSR + S_IRGRP + S_IWGRP
   + S_IROTH;

   fd = open( %trimr(filename): flags: mode: 1208 0);

O_CCSID gives it support for CCSIDs (vs O_CODEPAGE which only supports
code pages) and O_TEXT_CREAT eliminates the need to open the file, close
it, and then re-open it. The additional parameter to open() tells which
CCSID to translate from, so in my example, I used the special value of
0=Job CCSID. So it'll translate from the job's CCSID to 1208 (which is
UTF-8)

I found the issue with writing the IFS file using codepage=1028...

codepage=819; // 437 or 819 1208-UTF-8
fd=open(%trim(filename):flags:mode:codepage);
callp close(fd);

flags=O_RDWR+O_TEXTDATA;
fd=open(%trim(filename):flags);

The last calls to the flags needed to just be O_RDWR.

Changing to 1208 on the write didn't make a difference. I still get the same error. I'm trying to get up with the technical people on the other end to see what was actually received to trigger the error. So far, no luck.

Jay,

1208 isn't a code page, it's a CCSID. UTF-8 is much more than just a
single code page.

When you say "nothing gets written", this sounds an awful lot like a
coding error. Can you show us how you're writing this XML?

Having said that, I can't see why using 1208 vs 819 would have any
impact on the specific error you're getting. I agree that 1208 is
better, mind you -- but I don't think it'll be the solution to the
immediate problem.

I tried the 1208 codepage for the creation of the XML file. The problem is that nothing gets written to the IFS file when set this way.

Even if the file looks fine on your PC and is displayed nicely in Firefox
and IE, I would create it with codepage 1208, which is UTF-8. Codepage 819
matches ISO-8859-1 of the west European languages.

Procedure http_url_post_stmf() does not do any character translation and
therefore there is no other option (beside the codepage of the stmf) to
change the codepage.

The XML is created on the IFS using codepage 819.

When it is downloaded to a PC, everything looks file. If I load it
to IE or FIREFOX, everything comes up perfectly.

Now that's a possibility.

What's the best way to force the encoding?

For me the error message implies that you do not send the XML in UTF-8

but

any other encoding. That way the server can not find the "<" character

at

the first position of the XML.

The error message:

<?xml version="1.0" encoding="UTF-8"?><error>XML Error: Fatal error:
Start tag expected, '<' not found at :1.</error>

What the server tries to read:

<?xml version="1.0" encoding="UTF-8"?>
<service_orders>

Because of the wrong encoding it can not find the "<" of "<?xml ...".

Nothing more than a guess.

Thomas.

I have that in there. Thanks though!

I hard coded it just during my original attempts to get it running.

It's running now. Just have an error with the XML (or their server
says there's an error).

I was looking in the httpapi_debug.txt file and noticed that the
filename line is missing a double quote at the end of the filename.
I doubt that is causing my issue...

Jay,

I know you've gotten past this point already, but... one tip for you
with regard to the following code:

if (rc <> 1);
msg = http_error(err);
dsply msg;
if err<>36;
callp http_crash();
return;
endif;
exsr $getPassword;
endif;

There are named constants in HTTPAPI_H for each error number. So
instead of coding err<>36, you could code err<>HTTP_NDAUTH. This is
just easier to read... HTTP_NDAUTH visually looks like 'Need
Authentication", whereas it's hard to say what '36' means. Even I
didn't know what it was without looking it up...

It's just a small tip, though... what you have will work okay, it's

just

not as nice to read.
