Json Data Question to a ESP32 Controller?

Post by Helmut_number_one »

I found nothing in Help File :
So if I send something like this to an ESP32 Annex Basic Controller: http://192.168.0.44/sensorList.json
That he sends me such an answer?
{"sensors":[
{"ID":"Untitled","Disp":0,"P1":0,"P2":0,"Val":0.00,"Min":-20,"Max":85,"U": "°C"}
]}
Is this possible?

Is no very clear for me but, is you want get the result of this url (http://192.168.0.44/sensorList.json) inside Annex you can simply use

Code: [Local Link Removed for Guests]

a$ = WGET$("http://192.168.0.44/sensorList.json")
If you want do the opposite (the url is an annex module), is possible too but not exactly with the same url.

In this case you can use the [Local Link Removed for Guests]event and use the url http://192.168.0.44/mgs

You have an example inside the help

Hi Helmut,

not exactly what you requested .... but take a look at the OnUrlMessage event and UrlMsgReturn


[Local Link Removed for Guests]

That give a way to return a string with almost any wanted contend as a reply to for example http://esp_local_ip/msg?x=1



EDIT: I was not really as fast as lightning .... but Francesco was faster than lightning :-)
