Virtual Device - Post JSON

[automyhome 0]

Hi All

 

I have spent hours reading manuals and forum posts trying to work this out and I can not get my head around it and I just cant find the answer I am looking for.

 

I would like to setup a virtual device button to do the following:

 

Perform a HTTP POST to

 

http://192.168.1.5/SystemON

 

with the content 

 

{
"SystemON":"on"
}

 

If someone could help me out, that would be fantastic.

Thanks Joep, I have made the change but I am still getting this error

[ERROR] 22:30:32: line 5: '}' expected near '

not sure if this information helps, but when i use a rest client it works, here is the log from the rest client

I don't know if it works, just a test because I have no access to my HC2.

hmmm, that returns the following error.

 

 

[ERROR] 23:02:12: line 1: attempt to index global 'net' (a nil value)

 

as soon as i remove the ' that you have added, the error goes away and returns back to the original error. It must be something to do with the format of

I think net.HTTPClient() doesn't supported in virtual device. (Scenes only)

Thanks cag0114 and Joep for your help.

 

I moved the code into a scene and made a few alterations and this is what has worked.

 

 

 

local http = net.HTTPClient()

    http:request("http://192.168.1.5/SystemON", {

        options = { method = 'POST', headers = {}, data = '{"SystemON":"on"}', timeout = 2000 },

 })
