Curl Request to Lua - ralwet - 16.11.2019

Hi

Due to the changes of apixu doing their new api, I want to implement another API from our local provider in Switzerland (https://developer.srgssr.ch/content/quickstart-guide).

Curl-Request is working. But I do struggle implementing the Curl-Call in Lua.

Working Curl:

Code:
curl -v -X POST 'https://api.srgssr.ch/oauth/v1/accesstoken?grant_type=client_credentials'   \
-H 'Authorization: Basic RFJNblFyV1lpRnN3VGVyS1pOVWpJUzFOQ00WDhHUzU6THlsMG5udGdoMXo2VWxxeg=='   \
-H 'Cache-Control: no-cache'   \
-H 'Content-Length: 0'   \
-H 'Postman-Token: 24264e32-2de0-f1e3-f3f8-eab014bb6d76'

The Curl-Request returns successfully a new bearer access-Token. Verbose-Response from Curl:

Now my Code in Lua:

Code:
require('json')
require('ssl.https')
require('ltn12')
require('encdec')

local response_body = {}
local request_body = ""
local body, code, hdrs, stat = ssl.https.request({
  url = 'https://api.srgssr.ch/oauth/v1/accesstoken?grant_type=client_credentials',
  sink = ltn12.sink.table(response_body),
  method = 'POST',
  headers = {
    ["Authorization"] = "Basic RFJNblFyV1lpRnN3VGVyS1pOVWpJUzFOQ00WDhHUzU6THlsMG5udGdoMXo2VWxxeg==",
    ["Cache-Control"] = "no-cache",
    ["Content-Length"] = 0,
    ["Postman-Token"] = "24264e32-2de0-f1e3-f3f8-eab014bb6d76"
  },
  source = ltn12.source.string(request_body)
})

log(body)
log(code)
log(hdrs)
log(stat)

Logs are returning

Code:
body: * nil
code: * string: closed
hdrs: * nil
stat: * nil

Can anybody see, why my Lua-Call is failing with "* nil"?

Thank you! Smile

Try installing newer firmware, older one uses SSLv3 by default for HTTPS which is not supported by most servers now.

RE: Curl Request to Lua - ralwet - 16.11.2019

I'm using a SpaceLynk HW3 (i.MX6) with firmware Version 2.4.0. As far as I know this is already the latest available firmware (https://www.se.com/ww/en/product/LSS100200/spacelynk-logic-controller).

Is this SpaceLynk firmware still using SSLv3?
