Send notifications via pushover

Try this, I've tested it with nginx and apache so other servers might reject this request. Fill params table with your post arguments, filedata variable should contain binary data of your jpeg image, set request url as needed.

Code:

require('ssl.https')

boundary = os.date('%d%m%Y%H%M%S')

params = {
 {
   name = 'token',
   value = '12345',
 },
 {
   name = 'user',
   value = 'testuser',
 },
 {
   name = 'attachment',
   filename = 'snapshot.jpg',
   ctype = 'image/jpeg',
   value = filedata,
 }
}

body = { '--' .. boundary }

for _, param in ipairs(params) do
 line = string.format('Content-Disposition: form-data; name=%q', param.name)
 if param.filename then
   line = string.format('%s; filename=%q', line, param.filename)
 end
 body[ #body + 1 ] = line

 if param.ctype then
   body[ #body + 1 ] = string.format('Content-Type: %s', param.ctype)
 end

 body[ #body + 1 ] = ''
 body[ #body + 1 ] = param.value
 body[ #body + 1 ] = '--' .. boundary
end

-- last boundary
body[ #body ] = body[ #body ] .. '--'
-- empty line at the end
body[ #body + 1 ] = ''

bodydata = table.concat(body, '\r\n')

resp = {}

log(
 ssl.https.request({
   url = 'https://...',
   sink = ltn12.sink.table(resp),
   method = 'POST',
   source = ltn12.source.string(bodydata),
   headers = {
     ['content-length'] = #bodydata,
     ['content-type'] = 'multipart/form-data; boundary=' .. boundary
   }
 })
)

log(table.concat(resp))

Thanks admin for the fast response! Will try it out.

Thanks I will try it.
