Thanks so much; however, I'm still having trouble getting the lights to respond. I had to alter your example somewhat, because Racket was complaining about an "in-string: contract violation". The following seems to work:
(http-sendrecv "192.168.1.95" "/api/<username>/lights/1/state" #:method 'PUT #:data (alist->form-urlencoded (list (cons 'bri "1") (cons 'ct "500"))) #:headers '("Content-Type: application/x-www-form-urlencoded")) However, instead of affecting the light, I just get the following on the REPL: #"HTTP/1.1 200 OK" '(#"Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0" #"Pragma: no-cache" #"Expires: Mon, 1 Aug 2011 09:00:00 GMT" #"Connection: close" #"Access-Control-Max-Age: 3600" #"Access-Control-Allow-Origin: *" #"Access-Control-Allow-Credentials: true" #"Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE, HEAD" #"Access-Control-Allow-Headers: Content-Type" #"Content-type: application/json") #<input-port:pipe> I've also tried sending the message using: #:data (form-urlencoded-encode "\"bri\": 1") and changing the #:headers to '("Content-Type: application/json") Any thoughts?
