Building a Simple TCP Server

require "socket"
server = TCPServer.new(1234)
while connection = server.accept
  while line = connection.gets
    break if line =~ /quit/
    puts line
    connection.puts "Received!"
  end
  connection.puts "Closing the connection. Bye!"
  connection.close
end
 
# To test
# telnet 127.0.0.1 1234



Creating a Web Server with thread support

require "thread"
require "socket"
class RequestHandler
    def initialize(session)
    @session = session
    end
    def process
        while @session.gets.chop.length != 0
        end
        @session.puts "HTTP/1.1 200 OK"
        @session.puts "content-type: text/html"
        @session.puts "" # End of headers
        @session.puts "<html>"
        @session.puts "   <body>"
        @session.puts "     <center>"
        @session.puts "        <b>#{Time.now}</b>"
        @session.puts "     <center>"
        @session.puts "   </body>"
        @session.puts "</html>"
        @session.close
    end
end
server = TCPServer.new("0.0.0.0", "8888")
$currentRequests = []
$requestedToShutDown = false
while !$requestedToShutDown
    session = server.accept
    thread = Thread.new(session) do |newSession|
        RequestHandler.new(newSession).process
    end
    $currentRequests.push(thread)
end
$currentRequests.each { |t| Thread.join(t) }



Multi-Client TCP Servers

require "socket"
server = TCPServer.new(1234)
loop do
  Thread.start(server.accept) do |connection|
    while line = connection.gets
      break if line =~ /quit/
      puts line
      connection.puts "Received!"
    end
    connection.puts "Closing the connection. Bye!"
    connection.close
  end
end



To create a simple Web server, you can accept connections on the IP address 0 and the port number 80

require "socket"
server = TCPServer.new("0.0.0.0", 80)
loop do
  socket = server.accept
while socket.gets.chop.length > 0
end
socket.puts "HTTP/1.1 200 OK"
socket.puts "Content-type: text/html"
socket.puts ""
socket.puts "<html>"
socket.puts "<body>"
socket.puts "<center>"
socket.puts "<h1>#{Time.now}</h1>"
socket.puts "</center>"
socket.puts "</body>"
socket.puts "</html>"
socket.close
end
