You can find several examples of doing synchronous JSON requesting and 
parsin by googling "luci require httpclient", but if you need to do it 
asynchronously you'll need to tell us when exactly you're trying to do 
what. Asynchronous to what?

Here are some good examples of synchronous JSON from the fonera folks:
