Re: YAJL procedures

You don't really even need to define a based-on variable. If you have a
pointer myPointer then, in debug, just define how you want it
treated/formatted as in:

eval myPointer:c 10 to display the first ten bytes addressed by myPointer
as a character string
eval myPointer:x 50 to display the first fifty bytes addressed by
myPointer in hex

Yup. Just that simple.

Rob,

Yes... a web service that uses JSON payload.

http_post() requires only 4 parameters. I'm passing 7 (including the
peResponse, peTimeoute, peUserAgent, and peContentType)

The 8th parameter is SoapAction. This is not a SOAP webservice.

Thanks.

Jon - so you just define a variable "based-on" the pointer?

Greg, I think you're missing a parameter. http_post accepts 8 parameters
but you only show 7. Check after jsonLen. There should be peFilename
and
peTimeout. In your example response may represent one of these.

Also, I'm not sure what you mean by a json web service but I have to
call a
web service and pass a json body (this may be what you mean). I use
http_url_post_raw(). So my call looks like

rc = http_url_post_raw(url: %Addr(jsonStr): %Len(%Trim(jsonStr)) :1
:%paddr('INCOMING')
:HTTP_TIMEOUT :HTTP_USERAGENT
:'application/json');.

Since I'm going to use this with http_post() (which uses a pointer).
So I
might as well do this and forgo the string? I just like to "see" stuff
in
debug.

yajl_endObj();
rc = yajl_getBuf(jsonPtr:jsonLen);
rc = http_post( URL
: jsonPtr
: jsonLen
: response
: HTTP_TIMEOUT
: HTTP_USERAGENT
: 'application/json');
yajl_genClose();

Subject: YAJL procedures

I need to get a very small JSON data set into varchar(1024) variable...

Just wondering which YAJL procedure is the easiest to use?

yajl_getBuf()
yajl_copyBuf()
yajl_copyBufStr()

For whatever reason, I've always just written it to the IFS before
posting.
