As Weather Underground will stop its free service soon I am trying to adapt my lua scripts to use forecast data from DarkSky.

The DarkSky API works only with https requests. Thus I only get the reply "Bad Request" instead of the JSON reply if I use the following code to access the DarkSky forecast.

Code: Select all

    io = require('io')
    http = require('socket.http')
    json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")()
    reply = http.request("https://api.darksky.net/forecast/[APIcode]/[lat],[lon]?units=si")
    print(reply)

Of course I replaced the [] section with my own data.
How can I make a https request in lua (I am still using Domoticz V3.5877 for other compatibility reasons)?

if it helps this is the code snippet that collects the data from the script I use:

Code: Select all


function os_capture(cmd, raw)
    local f = assert(io.popen(cmd, 'r'))
    local s = assert(f:read('*a'))
    f:close()
    if raw then return s end
    s = string.gsub(s, '^%s+', '')
    s = string.gsub(s, '%s+$', '')
    s = string.gsub(s, '[\n\r]+', ' ')
    return s
end

local api_key="mykey" -- darksky secret key
local coord="lat, long"                 -- latitude,longitude

-- Querying Darksky --
json = (loadfile "/home/alan/domoticz/scripts/lua/JSON.lua")()  -- For Linux
result=os_capture('curl -s "https://api.darksky.net/forecast/'..api_key..'/'..coord..'?lang=en&units=ca&exclude=hourly,flags"')

YES! That does the trick.
Thanks a lot, you saved my day (and my big domiticz installation).
