I'm trying to turn on and off a device using Pd by sending a URL. At the moment to turn the device on I just type in a url in the browser and to turn it off I type in another one url . To turn the device on I send http://192.168.1.123/relay/0/?turn=on To turn the device off I send http://192.168.1.123/relay/0/?turn=off
I can connect to the device using *connect* and *netsend* but I couldn't find an example / correct syntax / format on how to send the required url out of Pd.
This is what I'm using below
#N canvas 162 516 623 513 10; #X msg 535 750 ; pd dsp 1; #X obj 536 724 loadbang; #X obj 248 207 netsend; #X msg 272 110 disconnect; #X floatatom 218 272 0 0 0 0 - - -; #X obj 280 275 print; #X msg 403 171 send /relay/0/?turn=off; #X msg 404 136 send /relay/0/?turn=on; #X msg 184 67 connect 192.168.1.123 80; #X connect 1 0 0 0; #X connect 2 0 4 0; #X connect 2 0 5 0; #X connect 2 1 5 0; #X connect 3 0 2 0; #X connect 6 0 2 0; #X connect 7 0 2 0; #X connect 8 0 2 0;

that won't work. when using [send ...(, Pd will use FUDI [1] at the application layer. but you want to communicate with a webserver, so you need to use HTTP as the application layer protocol. the *actual* string (in HTTP) you want to send is something like:
GET /relay/0/?turn=off HTTP/1.0
you can use [netsend] to send raw bytes (using the "-b" mode). you also can use [list totext] to convert symbols to their byte-representation (translating the characters to ASCII). since [list totext] only takes single symbols (and not entire messages), an even easier way would be to use [fudiformat], which will convert a message into it's FUDI representation (with trailing semicolon, and everything). just strip of the unwanted characters (the trailing semicolon), and append proper CRLF terminators and you should be done.
something like:
| [symbol on] | [GET /relay/0/?turn=$1 HTTP/1.0( | [fudiformat] | [t l l] | [list length] | [- 2] [list split] | [list append 13 10 13 10] | [list prepend send] | [list trim] | [netsend -b]

Hey Johannes,
I guess you mean [list fromsymbol] to convert symbols to their byte-representation ? ;) ++

Have you tried [fudiformat]?
I think IOhannes actually meant it.

that patch misses the argument to [list split]. the purpose of [list split] is to remove the ";\n" at the end of the FUDI-message, so we calculate the length of the list minus 2 (for the two characters to split off). my ascii-art was a bit fuzzy there, but essentially the outlet of [- 2] was meant to go into the 2nd inlet of [list split].
gfmsard IOhannes
you can actually use [fudiformat -u] to omit the separator (; + newline), so you wouldn't need [list split]

Thanks I made those changes. I thought I would be able to pick up Pd again after several years of not using it. CLEARLY I was wrong :-) . I'm going to go back and re-watch Rafael Hernandez Pd tutorials again https://www.youtube.com/playlist?list=PL12DC9A161D8DC5DC They where very helpful several years ago and I can definitely see that I need a refresher. Thanks to everyone for being so patient and understanding.

yes, of course i meant [list fromsymbol] instead of the non-existing [list totext], for converting symbols to bytelists ( iwas confused by [text tolist])
Have you tried [fudiformat]?
I think IOhannes actually meant it.
yes, that is what i recommended for converting entire messages to bytelists.

If you don't have to use vanilla Pd it's easier to use [httpreq] and
[tcpclient].

Thanks all this really helps, my toggle / select is a little messy but it turns my Shelly1 device on and off from PureData.
Thanks

please don't!
switching the toggle to 1 will:
- send an "ON" message to the device
- send an "OFF" message to the device
- send a "connect" message to netsend
- send an "ON" message to the device
switching the togglle to 0 will:
- send an "ON" message to the device
- send an "OFF" message to the device
- send a "connect" message to netsend
- send an "OFF" message to the device
and this just accidentally happens to be like that. if you re-paint your patch from an image, it might as well do the following when switching the toggle to 1:
- send an "ON" message to the device
- send an "ON" message to the device
- send an "OFF" message to the device
- send a "connect" message to netsend
which clearly is just nonsense.
so why are you sending those odd "ON" and "OFF" messages and the beginning? you will also get ugly "already connected" errors, if you switch the device fast enough, so that the webserver has not terminated the connection yet.
the *first* rule you should learn when starting to patch in Pd, is using trigger, whenever you want to connect a single outlet to more than one inlets. everytime. always. every single time. really.
so remove the entire hickhack with your toggle and bang, and replace it by a simple:
[tgl] | [select 1 ] | | [on( [off( | ________/ |/ [symbol] |
then, between [list strip] and [netsend] do the following:
| [list strip] | [t a b] | | | [disconnect, connect 192.168.1.20 80( | ____/ |/ [netsend -b]
this will start a new connection exactly before you are going to send data to the webserver. and it will only send the HTTP-request once (with the correct parameters)

i use 2 options:
A) for osx and linux with ggee's shell
[curl -s http://192.168.1.123/relay/0/?turn=on( | [ggee/shell]
B) for win/lin/osx i prefer
[http://192.168.1.123/relay/0/?turn=on( | [mrpeach/httpreq] | | [connect 192.168.1.123 80( | / [mrpeach/tcpclient]
