Hello,

I want to send data to TRMNL server

this curl command is ok :

curl "https://trmnl.com/api/custom_plugins/xxxxxxxxxxxxxxxxxxxxxxxxxxx\
-H "Content-Type: application/json" \
-d '{"merge_variables": {"text":"Test", "author": "Pierre"}}' \
-X POST

but my lua code don't work:

Code:
-- Load modules
https = require('ssl.https')
ltn12 = require('ltn12')
json = require('json')

body ='{"merge_variables": {"text":"Test", "author": "Pierre"}}'

resp = {}
  body = json.encode(Body) 
  res, code, headers = https.request({
    url = 'https://trmnl.com/api/custom_plugins/xxxxxxxxxxxxxxxxxxxxxxxxxxx',
    method = 'POST',
    source = ltn12.source.string(body),
    sink = ltn12.sink.table(resp),
    headers = { 
                ['Content-Type'] = 'application/json',
                ['Content-Length'] = #body  
              }
  })
  -- handle feedback
  
    resp = table.concat(resp)
    resp = json.pdecode(resp)
  log(resp

Try this:

Code:
http = require('socket.http')
json = require('json')

url = 'https://trmnl.com/api/custom_plugins/xxxxxxxxxxxxxxxxxxxxxxxxxxx'

body = json.encode({
  merge_variables = {
    text = 'Test',
    author = 'Pierre',
  }
})

resp, code, headers = http.request({
  url = url,
  method = 'POST',
  body = body,
  headers = {
    ['Content-Type'] = 'application/json',
  }
})

resp = json.pdecode(resp)
log(resp)
