Hello,
Use (define-values (a b c) (http-send-recv ...)) as a remplacement for define
when you receive multiple values.
Or (let-values ([(a b c) (http-send-recv ...)]) ...) the same idea but for let.
You can search for binding ending with '-values'.

Hi Jay,
Sorry for this newbie question, but how do I grab just the third value.
Everything I try gets me an arity mismatch:
result arity mismatch;
expected number of values not received

If you're on linux, one dirty trick you could try is to start up a local
"web server" like netcat to just listen on the HTTP port and show you
the request that's happening:
nc -l -p 80
Then, point Curl and your Racket script to localhost and compare the
request sent by each.

The http-sendrecv function returns three values:
status : bytes?
header : (listof bytes?)
response : input-port?
You need to look at the third one for the response. You could pass it
to read-json or you could do port->string or anything else that you
can do with an input port.

John,
Thank you so much. That solved the problem of controlling the lights. However,
I still can't figure out how to get at the response from the Hue Bridge. I
should be receiving:
[
{"success":{"/lights/1/state/on":true}},
{"success":{"/lights/1/state/bri":170}},

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:

You probably want to use the net/http-client library, specifically the
http-sendrecv function. I’m not 100% sure, but I’d guess that the equivalent
Racket code for your curl command would look something like this.
(require net/http-client
net/uri-codec)
(http-sendrecv
