Synopsis

local parser = require "resty.multipart.parser"

ngx.req.read_body()

local body = ngx.req.get_body_data()

local p, err = parser.new(body, ngx.var.http_content_type)
if not p then
   ngx.say("failed to create parser: ", err)
   return
end

while true do
   local part_body, name, mime, filename = p:parse_part()
   if not part_body then
      break
   end
   ngx.say("== part ==")
   ngx.say("name: [", name, "]")
   ngx.say("file: [", filename, "]")
   ngx.say("mime: [", mime, "]")
   ngx.say("body: [", part_body, "]")
end

Description

This Lua library provides a simple parser for the multipart data format. Unlike the lua-resty-upload library, this parser does not support streaming processing of file uploads using the multipart format. However, it is more flexible in that it can be used to parse buffered request bodies read by the builtin request body reader of the NGINX core.

Anyway, be very careful when using this for large file uploads. Use lua-resty-upload instead.

TODO

• Better error reporting.
