Re: receiving POST encoded in JSON

No I just generated a big test JSON from http://www.json-generator.com/
and stuck it in my IFS, then used both service programs to parse it.....so
this is just the parser that I was benchmarking as this is the slow bit. I
haven't retrieved anything from the parsed result yet.

Kevin

is it a test program that just creates 140 K JSON in a loop

JSON from RPGNEXTGEN.COM (that is what we use at the moment)

I'm also looking into YAJL, but what are you comparing ?

Well, a staggering difference - using a 140kb JSON as a benchmark

JSON parse=16107ms
YAJL parse=53ms

I think I'm going to have to compare take a closer look at YAJL to
properly compare it to JSON from rpgnextgen.com. The latter is
attractive because it is written entirely in RPG and the procedure
names seem a bit more intuitive (e.g. json_parse() compared to
yajl_tree_load_buf() ) - however as YAJL is, I believe, written in C
it might bring some performance benefits.

Raul,

I don't understand your complaint about calling QtmhRdStin? it's
an

extremely simple call, and then your JSON data is loaded into a
variable in your program, and you can parse it. What could be simpler?

If you're interested in YAJL, you can use the yajl_tree_load_buf()

procedure to load the buffer you got from QtmhRdStin() to parse the
JSON, and then you'll have a yajl tree that you can extract the data

from.

There's info on parsing XML with yajl in the following handout (this
is from talks I give on yajl):

http://www.scottklement.com/presentations/Working%20with%20JSON%20
in
%2
0RPG.pdf

I've been considering adding a wrapper to my YAJL tools that does
the

call to QtmhRdStin() for you so you don't have to code it by hand --
this wouldn't save you all that much, really, just eliminates the
need

to code

it each time. Would that be more attractive to you? (That's

basically

what CGIDEV2 does, after all.)

CGIDEV seems to ignore this data. With another company I used
QtmhRdStin, but I wonder if there is an easier way to read it.

I installed YAJL from Scot's site, but it seems that is great to
create json and to parse it, but I did not find how to receive it.

According to this: http://www.w3.org/TR/html-json-forms/ browsers
will be able to send json encode data.

Here is part of the document they send me.
