Re: receiving POST encoded in JSON

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

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.)
