Here's a snippet I've used to accept HTTP POST of a file to in
luci...
http = require("luci.http")
local method = http.getenv("REQUEST_METHOD")
local pathinfo = http.getenv("PATH_INFO") -- from luci
--- if method == post and path info == allowed for your requirements.
http.setfilehandler(
function(meta, chunk, eof)
-- If this was multipart form, make sure to only accept the
documented form field.
-- return true to continue with subsequent chunks.
if meta and (meta.name ~= "raw") then return true end
if not file then
-- Don't trample a file if we don't get any data.
if not chunk then return false end
file = io.open(file_path, "w")
end
if chunk then
file:write(chunk)
end
if eof then
file:close()
end
return true
end
)
-- trigger handler!
http.content()
