Make a HTTP request to unicorn over a UNIX socket

unix_socket_request.rb

require "socket"

# edit these
socket_path = "tmp/sockets/unicorn.sock"
host = "example.com" # HTTP 1.1 requires a Host header
path = "/"

# connect
sock = UNIXSocket.new(socket_path)

# make request
sock.write("GET #{path} HTTP/1.1\r\nHost: #{host}\r\n\r\n")

# read/print the status line
status = sock.readline.chomp
puts status
headers = {}

# read/print the headers
while true
  line = sock.readline.chomp
  puts line
  break if line.empty?
  key, value = line.split(/: */, 2)
  headers[key.downcase] = value
end

# attempt to read the rest of the request
# hopefully we got a Content-Length, and not Transfer-Encoding: chunked
sock.read(headers["content-length"].to_i)

sock.close
