need a little coding assistance with sending image with pushover message from lua and curl

[dre68]

Can someone help me out getting curl correctly into my lua script?
I send a pushover message with lua function below:

Code: Select all

function My.NotifyMe(iMode, sTitle, sBody, sSound, sDevice)
   -- iPriority = -2,-1,0,1,2
   -- sTitle = title of message
   -- sBody = message
   -- sSound = sound, empty is default sound
   -- sDevice = your device name, empty is all devices
   -- Check for optional sound and device parameter
   if sSound == nil then sSound = '' end
   if sDevice == nil then sDevice = '' end
   local iPriority
   local sUserKey
   local sToken ='aaaaaaa'
   --choose which receipient group and priority
   if iMode == 'Plant' then 
   	iPriority = '0'
   	sUserKey = 'xxxxxxx'
   elseif iMode == 'Alarm' then
    iPriority = '2'
   	sUserKey = 'yyyyyy'
   else
   	iPriority = '0'
   	sUserKey = 'zzzzzz'   
   end 
   -- Replace any percent signs with their ascii values, as they are special characters
   sTitle = string.gsub(sTitle, '%%', '%%25')
   sBody = string.gsub(sBody, '%%', '%%25')
   local sMsg = 'curl --data "token=' .. sToken .. '&user=' .. sUserKey .. '&title=' .. 
   sTitle .. '&message=' .. sBody .. '&priority=' .. tostring(iPriority) .. '&sound=' ..
   sSound .. '&device=' .. sDevice .. '"  https://api.pushover.net/1/messages.json'
   os.execute(sMsg)
end

I would like to have a photo as attachment to the pushover message, which is possible according to the pushover help

the code provided as an example for that is:

Code: Select all

curl -s \
 --form-string "token=APP_TOKEN" \
 --form-string "user=USER_KEY" \
 --form-string "message=here is an image attachment" \
 -F "attachment=@/path/to/your/image.jpg" \
 https://api.pushover.net/1/messages.json

how do I integrate the attachment piece of code : -F "attachment=@/path/to/your/image.jpg" \
into my function?
