HTTP request to API

[skribb]

i want to try and make HTTP requests to the LIFX api. Currently I use a python script in Eventghost.

Code: Select all

import requests

token = "xxxxxxxxxxxxxxxxxxxxxxxxxx"

headers = {
    "Authorization": "Bearer %s" % token,
}

payload = {
    "power": "on", "duration": 0.1, "color": "white brightness:1.0 kelvin:4500"
}

response = requests.put('https://api.lifx.com/v1/lights/all/state', data=payload, headers=headers)

##### kelvin is a little miffy. sometimes it works to change it, sometimes it doesn't

How would I implement the same in AHK?


Thanks a lot guys

I kinda like the library Requests, so I would suggest you keep using Python, if you want to control it using AHK, you can parse it parameters when you run it.

The AHK Script:

Code: Select all

#Include StdOutToVar.ahk

MsgBox, % LIFX_SetState("all", "on", "white kelvin:4500", 1.0, 0.1)

LIFX_SetState(selector, power, color, brightness, duration){
	return StdOutStream("python LIFX.py " """" selector """ """ power """ """ color """ """ brightness """ """ duration """")
}

The Python Script:

Code: Select all

import requests, sys

def LIFX_SetState(selector, power, color, brightness, duration):
	try:
		s = requests.Session()
		headers = {"Authorization": "Bearer " + "xxxxxxxxxxxxxxxxxxxxxxxxxx"}
		payload = {"power": power, "duration": duration, "color": color, "brightness": brightness}
		
		response = s.put("https://api.lifx.com/v1/lights/" + selector + "/state", data = payload, headers = headers)
		return JsonToStr(response)
	except:
		return "Error"

def JsonToStr(response):
	res = ""
	for key in response:
		res += key + ": ["
		for light in response[key]:
			res += "{"
			for key in light:
				res += key + ": " + light[key] + ", "
			res = res[0:-2] + "},"
		res = res[0:-1] + "],\n"
	return res[0:-2]

print(LIFX_SetState(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5]), end = "")

You will also need this Script by Sean, HotKeyIt and SKAN.

Code: Select all

	VarSetCapacity(Buffer, 4096, 0), nSz := 0
	
	While DllCall("ReadFile", "UInt", hPipeRead, "UInt", &Buffer, "UInt", 4094, "UIntP", nSz, "Int", 0) {
		tOutput := (AIC && NumPut(0, Buffer, nSz, "Char") && VarSetCapacity(Buffer, -1)) ? Buffer : %StrGet%(&Buffer, nSz, "CP850")
		
		Isfunc(Callback) ? %Callback%(tOutput, A_Index) : sOutput .= tOutput
	}

A little disclaimer, since I neither have a LIFX bulb nor an access token I haven't been able to test this, but I have been using the same setup https://autohotkey.com/boards/viewtopic ... 609#p93609.

I kinda like the library Requests, so I would suggest you keep using Py[/url].

When running the script all I get is a blank msgbox. I have installed Python 3.5.2 which I figured would be needed

[Capn Odin]

I think Python 3.3 would suffice, but try this.

Code: Select all

import requests, sys

def LIFX_SetState(selector, power, color, brightness, duration):
	try:
		s = requests.Session()
		headers = {"Authorization": "Bearer " + "xxxxxxxxxxxxxxxxxxxxxxxxxx"}
		payload = {"power": power, "duration": duration, "color": color, "brightness": brightness}
		
		response = s.put("https://api.lifx.com/v1/lights/" + selector + "/state", data = payload, headers = headers)
		print(response.text)
		return response.json()
	except:
		return "Error"

print(LIFX_SetState(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4], sys.argv[5]), end = "")

You should be guaranteed to get some response if it work now, and I hate saying this but I assume you have used your access token.
This should help debugging the problem.

Edit: Sorry, I don't know why I wrote this so incoherently.
