To provide some additional information, the following Curl command sent to httpbin.org/post..
local url_open = 'curl -u "username:password" -F "title=Companies House File" -F "correspondent=12" -F "document=@/mnt/nas/10.pdf" http://httpbin.org/post'
local command = io.popen(url_open)
local result = command:read("*a")
print(result)
Returns the following, which looks good…
{
"args": {},
"data": "",
"files": {
"document": "data:application/octet-stream;base64,JVBERi0xLjMNJeLjz9MNCjIyNyAwIG9iag08PCANL0xpbmVhcml6ZWQgMSANL08gMjMxIA0vSCBbIDIzNTAgODc5IF<REDACTED>T5dDT4+DXN0YXJ0eHJlZg0xNzMNJSVFT0YN"
},
"form": {
"correspondent": "12",
"title": "Companies House File"
},
"headers": {
"Accept": "*/*",
"Authorization": "Basic dXNlcm5hbWU6cGFzc3dvcmQ=",
"Content-Length": "66501",
"Content-Type": "multipart/form-data; boundary=------------------------1a4c10e40f1ccf8e",
"Host": "httpbin.org",
"User-Agent": "curl/7.38.0",
"X-Amzn-Trace-Id": "Root=1-6360dbdb-6bea68142a74a1762e74ca04"
},
"json": null,
"origin": "82.30.93.28",
"url": "http://httpbin.org/post"
}
Then using the following Lua code to try and achieve the same thing..
local http = require("socket.http")
local ltn12 = require("ltn12")
local mime = require("mime")
local lfs = require("lfs")
local username = "username"
local password = "password"
local httpendpoint = 'http://httpbin.org/post'
local filepath = "/mnt/nas/10.pdf"
local file = io.open(filepath, "rb")
local contents = file:read( "*a" )
-- https://stackoverflow.com/questions/3508338/what-is-the-boundary-in-multipart-form-data
local boundary = "-----BoundaryePkpFF7tjBAqx29L"
local send = "--"..boundary..
"\r\nContent-Disposition: form-data; title='Companies House File'\r\n"
.."----"..boundary..
"\r\nContent-Disposition: form-data; document="..filepath..
"\r\nContent-type: application/pdf".."\r\n"
..contents.."\r\n"
.."------"..boundary.."--\r\n"
-- Execute request (returns response body, response code, response header)
local resp = {}
local body, code, headers, status = http.request {
url = httpendpoint,
method = 'POST',
headers = {
["Authorization"] = "Basic " .. (mime.b64(username ..":" .. password)),
["Content-Length"] = lfs.attributes(filepath, 'size'),
['Content-Type'] = "multipart/form-data; boundary="..boundary,
},
-- source = ltn12.source.file( io.open(filepath,"rb") ),
source = ltn12.source.file( io.open(send) ),
sink = ltn12.sink.table(resp)
}
print(body, code, headers, status)
print(table.concat(resp))
if headers then
for k,v in pairs(headers) do
print(k,v)
end
end
I get this returned..

It’s clear I’m not getting the content sent in the right format/structure, but I cannot find any guidance that clearly explains how to construct a multi-part form submissions via Lua code..
Hoping someone can help…
