How to HTTP POST from an action?

[alistair@fred]

I'm working on a Skin that is accessing data from a very basic (home grown) home automation system.

One of the things I want to do is have a button that when clicked will turn a light on or off.

I already have a measure that gets the current state of the light (HTTP GET from a REST API), but I'm struggling with how to do an HTTP POST or PUT to change the state of the light.

Possible approaches I have considered:
1) Using WebParser - problem is I can't see any way to set the request method to POST
2) Lua script - according to the docs 'require' is not supported, so I don't know how to get http support in Lua
3) Custom plugin - I hoped there might already be one

I'm not afraid of writing a bit of C++ if that's what it takes, but I'd prefer not to.

Any suggestions or hints would be appreciated.

Can you do this from your browser, via command line or anyway else?

WebParser is GET-only. As mentioned above, you can use curl from a PowerShell command line (using a CommandMeasure).

Thanks for the suggestions.

I thought about using curl after I'd posted my query last night. I'm at work at the moment, so will give it a try tonight...

I've managed to do this using curl, as suggested.

The measure that does the work looks like this:

Code: Select all

[measureToggleLights]
Measure=Plugin
Plugin=RunCommand
Parameter=curl --header "Content-Type: application/json" --request POST --data "{\"lightsOn\":#toggleLights#,\"timestamp\":0,\"id\":0}" http://192.168.2.211:34568/api/v1/lights
State=Show
DynamicVariables=1

The toggleLights variable gets set to true or false elsewhere. Note the escaping needed on the quotes to keep curl happy...

I hope this may be useful to someone else.

For sure it will, someday. Thanks for sharing your solution, you never know when someone else will need it.

Gooood! Hello! Also it can be reached with PowerShell:

Code: Select all

$postParams = @{username='me';moredata='qwerty'}
Invoke-WebRequest -Uri http://example.com/foobar -Method POST -Body $postParams

I will damn need this a bit later, so thank you.
