JSON

[James Sentman]

I’m having trouble duplicating this issue. When I run this it works fine but there may be some scripting things.

First I would use the “describe appleevent” verb instead of write log, that will show you exactly what the layout of the JSONData record is. Something like this and give it a hit:

on JSONRequest( formData, JSONData)
  write log “in JSON Request”
  describe appleevent JSONData

end JSONRequest

on my machine the output from that looks something like:

 'misc'\'DApl'{ '----':{ 'usrf':[ 'utxt'("moisture"), 90 ] }, &'subj':null(), &'csig':65536 }

and that is what I would expect. Thats a user record with one field named moisture with a value of 90. If that output looks similar then the problem is something else in the script which may be being hidden by the onerror handler. If you remove that then the actual error will get sent to the log and we can see what it’s really saying the error is. So then try something like this:

on JSONRequest(formData, JSONData)

	describe appleevent JSONData
	

	set moist to moisture of JSONData
	
	write log “moist is “ & moist

	set value of (thisUnit) to moist

	write log “set value is complete"
	
	send reply "success" return code 200 content type "text/plain"
	
end JSONRequest


and post the output of that in the log or the text of any errors that popup.
