Re: receiving POST encoded in JSON

Raul



You are right. Using QtmhRdStin is as simple as heart surgery. Anybody can
do it if the documentation says it as simple as “You just take the old
heart out and put a new one in”.



Unfortunately the world is not so simple and that is why some people use
thousands of hours creating coherent middleware while others uses the same
thousands of hours digging ditches and solving problems (others has soved)
“as they go”.



FYI - The result of the formula (simple + simple + simple + simple + simple
…) is not “more simple” but “more complicated” ;-)

I read over the docs, and, you are right, it is simple.
A wrapper will help, but it also will hide the possible errors, so
probably it is better to just call QtmhRdStin

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):

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.)

We are planing to wor with a company that will send us data as POST in

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.
