Convert cURL to Ruby

How cURL to Ruby works

The Ruby output uses Net::HTTP.start with a request block — method, headers, body, basic_auth and query string map one-to-one from the cURL flags. JSON bodies use request.body = payload.to_json with Content-Type application/json, urlencoded bodies use request.set_form_data, and multipart uploads use request.set_form for IO objects. SSL is enabled automatically for https:// URLs. The snippet uses URI.parse + URI#query for query string assembly so special characters are encoded correctly.

Ruby code example

Realistic GET + POST with headers and a JSON body, written using Net::HTTP (stdlib).

require "net/http"
require "uri"
require "json"

# GET with headers and query params
uri = URI("https://api.example.com/users")
uri.query = URI.encode_www_form(page: 1, limit: 50)
get_req = Net::HTTP::Get.new(uri)
get_req["Authorization"] = "Bearer YOUR_TOKEN"
get_req["User-Agent"]    = "MyApp/1.0"

users = Net::HTTP.start(uri.host, uri.port, use_ssl: true, read_timeout: 30) do |http|
  resp = http.request(get_req)
  raise "HTTP #{resp.code}" unless resp.is_a?(Net::HTTPSuccess)
  JSON.parse(resp.body)
end
puts users.size

# POST with JSON body
post_uri = URI("https://api.example.com/users")
post_req = Net::HTTP::Post.new(post_uri, {
  "Authorization" => "Bearer YOUR_TOKEN",
  "Content-Type"  => "application/json",
})
post_req.body = { name: "Ada Lovelace", email: "[email protected]" }.to_json

Net::HTTP.start(post_uri.host, post_uri.port, use_ssl: true) do |http|
  created = http.request(post_req)
  puts created.code
end
