custom event trigger json output possible?

[_Cyber_]

hello,

is there a possibility to get a json-output by http for a custom event triggered?

e.g.: http://192.168.10.242/control?cmd=event,poweroff

reply is "OK" - which is in nodered then not with the same nodes parseable as e.g. http://192.168.10.242/json?view=sensorupdate&tasknr=4 or http://192.168.10.242/control?cmd=GPIO,2,0

thanks.

Hi alois,

what json output you would like to see for a custom event since a lot can happen in an event?

when i need a html feedback i use a command like yours:
e.g.: http://<espip>/control?cmd=event,toogle

and then do another request for the response:
e.g.: http://<espip>/csv?tasknr=1&valuenr=1&header=0

(i use this for shortcuts in ios to toggle a relay..so i get the state of the relay as a feedback. in this example a simple 1 or 0)

the "OK" would be already enough output, but it is not json.

so if it would be e.g.:
{
"reply": "OK"
}

or, to be distinguishable e.g.:
{
"event,<eventname>": "OK"
}

it would be parseable with a "generic" HTTP request node in nodered where also other commands (with valid json output - see above) are fed in.

another small issue with json-replys, is this already known?
