HTTP PUT image to 2N intercom

[admin]

Try this. filedata variable must contain your image in JPEG format. Use io.readfile() to read a local file.

Code:

require('ltn12')
require('ssl.https')

boundary = os.date('%d%m%Y%H%M%S')
filedata = '...' -- image data as a binary string

body = table.concat({
  '--' .. boundary,
  'Content-Disposition: form-data; name="blob-image"; filename="picture.jpeg"',
  'Content-Type: image/jpeg',
  '',
  filedata,
  '--' .. boundary .. '--',
  ''
}, '\r\n')

resp = {}

res, code, response_headers, status = ssl.https.request({
  url = 'https://test:test@10.0.0.230/api/display/image?display=ext1',
  sink = ltn12.sink.table(resp),
  method = 'PUT',
  source = ltn12.source.string(body),
  headers = {
    ['content-length'] = #body,
    ['content-type'] = 'multipart/form-data; boundary=' .. boundary
  }
})

log(res, code, table.concat(resp))

For digest auth you can use this example: https://forum.logicmachine.net/showthrea...64#pid9364
Replace ssl.https.request in the above code with request from the digest code.
