Going back to your original message, it appears that the data was encoded as

Try using this code to generate the data:

[racket-users] http-sendrecv puts ##f in post-bytes if unspecified?
It appears to me that if you call http-sendrecv with a method of ‘POST, but fail to specify body bytes, that the request goes out with the two-byte string “#f” as the body. I can’t imagine that this would often be the right thing. Wouldn’t it make more sense just to signal an error if the method is ‘POST and no body bytes are specified? Thanks!

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

Re: [racket-users] Sending RESTful Commands using Racket
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.

Re: [racket-users] web-server/insta restart
As far as I know, there's nothing in DrRacket for it to Stop and then Start again when you save the file. It's fairly easy to that in Emacs, which I do when I'm working on stuff like that (actually, I have it so my Start command includes SaveStop.) If you are expecting the continuations and other saved state to update, you should read the FAQ on this: http://docs.racket-lang.org/web-server/faq.html?q=faq#%28part._update-servlets%29 Jay On Wed, Jun 17, 2015 at 10:11 AM, mail.tas...@gmail.com wrote: Hi, how can I make the already run server restart automatically each time I save the file?

Re: [racket-users] Sending RESTful Commands using Racket
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.

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}},
{success:{/lights/1/state/ct:500}}
]
I'm having the same problem when I use GET to inquire about the state of the
lights.
My best,
Bruce

Oops forgot to cc: group:
Going back to your original message, it appears that the data was encoded as
JSON, not using a urlencoding (that would make sense for a GET, but not for
a PUT or POST).
Try using this code to generate the data:
#lang racket
(require json)
(jsexpr-string
(hash 'on #t
'bri 170
'ct 500))
Let me know if you want me to stuff it into the http-sendrecv call.
John
(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

I've also tried sending the message using:
#:data

and changing the #:headers to '(Content-Type: application/json)
Any thoughts?

[racket-users] DrRacket rendering issues OS X
Good day all! First, I just wanted to say DrRacket is *amazing* and thank all who have helped it become what it is today! I'm currently using it to work on Typed Racket and it is a godsend. Right now, unfortunately, I am having some problems w/ DrRacket rendering in OS X -- I am getting large black areas appearing in full screen mode in DrRacket. They seem pretty serious/severe, and I was curious if anyone else has seen this behavior? PDF w/ screenshots some attempt to describe problem(s): https://drive.google.com/file/d/0B-HcU1nZPrwJWXFNbEdOV0doeUE/view?usp=sharing Steps that seem to recreate issue: 1) Open DrRacket 2) Make it full screen by clicking green button at top left of DrRacket 3) Open OS X ‘Mission Control’ (cmd+up or 3-finger-swipe up on touchpad) 4) Close OS X ‘Mission Control’ (cmd+down or 3-finger-swipe downon touchpad) nd 5) Repeat 3-4 a couple times (after the 2 time it seemed to consistently happen on my machine) - This worked whether or not I was plugged into the external monitor - the snapshots reproduced the issue on were the Racket plus Tests | Mac OS X | 32-bit Intel distribution for version 6.2.0.4 (20150609-bf12a2b) version 6.2.0.4 (20150617-97827ac) - I’m running the latest OS X Yosemite (Version 10.10.3 (14D136)) on a early 2013 13” MacBook Air Best, Andrew -- You received this message because you are subscribed to the Google Groups Racket Users group.
