http-form_data

HTTP::FormData

Utility-belt to build form data request bodies.

Installation

Add this line to your application's Gemfile:

gem 'http-form_data'

And then execute:

$ bundle

Or install it yourself as:

$ gem install http-form_data

Usage

require "http/form_data"

form = HTTP::FormData.create({
  :username     => "ixti",
  :avatar_file  => HTTP::FormData::File.new("/home/ixti/avatar.png")
})

# Assuming socket is an open socket to some HTTP server
socket << "POST /some-url HTTP/1.1\r\n"
socket << "Host: example.com\r\n"
socket << "Content-Type: #{form.content_type}\r\n"
socket << "Content-Length: #{form.content_length}\r\n"
socket << "\r\n"
socket << form.to_s

It's also possible to create a non-file part with Content-Type:

form = HTTP::FormData.create({
  :username     => HTTP::FormData::Part.new('{"a": 1}', content_type: 'application/json'),
  :avatar_file  => HTTP::FormData::File.new("/home/ixti/avatar.png")
})

Supported Ruby Versions

This library aims to support and is tested against the following Ruby versions:

• Ruby 3.2
• Ruby 3.3
• Ruby 3.4
• Ruby 4.0

If something doesn't work on one of these versions, it's a bug.

This library may inadvertently work (or seem to work) on other Ruby versions, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version or implementation, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
