Constructor Details

#initialize(filename_or_io, content_type, filename = nil, opts = {}) ⇒ UploadIO

Create an upload IO suitable for including in the params hash of a Net::HTTP::Post::Multipart.

Can take two forms. The first accepts a filename and content type, and opens the file for reading (to be closed by finalizer).

The second accepts an already-open IO, but also requires a third argument, the filename from which it was opened (particularly useful/recommended if uploading directly from a form in a framework, which often save the file to an arbitrarily named RackMultipart file in /tmp).

Examples:

UploadIO.new("file.txt", "text/plain")
UploadIO.new(file_io, "text/plain", "file.txt")

def initialize(filename_or_io, content_type, filename = nil, opts = {})
  io = filename_or_io
  local_path = ""
  if io.respond_to? :read
    # in Ruby 1.9.2, StringIOs no longer respond to path
    # (since they respond to :length, so we don't need their local path, see parts.rb:41)
    local_path = filename_or_io.respond_to?(:path) ? filename_or_io.path : "local.path"
  else
    io = File.open(filename_or_io)

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args) ⇒ Object
