# = WEB server toolkit.
|
|
#
|
|
# WEBrick is an HTTP server toolkit that can be configured as an HTTPS server,
|
|
# a proxy server, and a virtual-host server. WEBrick features complete
|
|
# logging of both server operations and HTTP access. WEBrick supports both
|
|
# basic and digest authentication in addition to algorithms not in RFC 2617.
|
|
#
|
|
# A WEBrick server can be composed of multiple WEBrick servers or servlets to
|
|
# provide differing behavior on a per-host or per-path basis. WEBrick
|
|
# includes servlets for handling CGI scripts, ERb pages, Ruby blocks and
|
|
# directory listings.
|
|
#
|
|
# WEBrick also includes tools for daemonizing a process and starting a process
|
|
# at a higher privilege level and dropping permissions.
|
|
#
|
|
# == Starting an HTTP server
|
|
#
|
|
# To create a new WEBrick::HTTPServer that will listen to connections on port
|
|
# 8000 and serve documents from the current user's public_html folder:
|
|
#
|
|
# require 'webrick'
|
|
#
|
|
# root = File.expand_path '~/public_html'
|
|
# server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => root
|
|
#
|
|
# To run the server you will need to provide a suitable shutdown hook as
|
|
# starting the server blocks the current thread:
|
|
#
|
|
# trap 'INT' do server.shutdown end
|
|
#
|
|
# server.start
|
|
#
|
|
# == Custom Behavior
|
|
#
|
|
# The easiest way to have a server perform custom operations is through
|
|
# WEBrick::HTTPServer#mount_proc. The block given will be called with a
|
|
# WEBrick::HTTPRequest with request info and a WEBrick::HTTPResponse which
|
|
# must be filled in appropriately:
|
|
#
|
|
# server.mount_proc '/' do |req, res|
|
|
# res.body = 'Hello, world!'
|
|
# end
|
|
#
|
|
# Remember that +server.mount_proc+ must precede +server.start+.
|
|
#
|
|
# == Servlets
|
|
#
|
|
# Advanced custom behavior can be obtained through mounting a subclass of
|
|
# WEBrick::HTTPServlet::AbstractServlet. Servlets provide more modularity
|
|
# when writing an HTTP server than mount_proc allows. Here is a simple
|
|
# servlet:
|
|
#
|
|
# class Simple < WEBrick::HTTPServlet::AbstractServlet
|
|
# def do_GET request, response
|
|
# status, content_type, body = do_stuff_with request
|
|
#
|
|
# response.status = 200
|
|
# response['Content-Type'] = 'text/plain'
|
|
# response.body = 'Hello, World!'
|
|
# end
|
|
# end
|
|
#
|
|
# To initialize the servlet you mount it on the server:
|
|
#
|
|
# server.mount '/simple', Simple
|
|
#
|
|
# See WEBrick::HTTPServlet::AbstractServlet for more details.
|
|
#
|
|
# == Virtual Hosts
|
|
#
|
|
# A server can act as a virtual host for multiple host names. After creating
|
|
# the listening host, additional hosts that do not listen can be created and
|
|
# attached as virtual hosts:
|
|
#
|
|
# server = WEBrick::HTTPServer.new # ...
|
|
#
|
|
# vhost = WEBrick::HTTPServer.new :ServerName => 'vhost.example',
|
|
# :DoNotListen => true, # ...
|
|
# vhost.mount '/', ...
|
|
#
|
|
# server.virtual_host vhost
|
|
#
|
|
# If no +:DocumentRoot+ is provided and no servlets or procs are mounted on the
|
|
# main server it will return 404 for all URLs.
|
|
#
|
|
# == HTTPS
|
|
#
|
|
# To create an HTTPS server you only need to enable SSL and provide an SSL
|
|
# certificate name:
|
|
#
|
|
# require 'webrick'
|
|
# require 'webrick/https'
|
|
#
|
|
# cert_name = [
|
|
# %w[CN localhost],
|
|
# ]
|
|
#
|
|
# server = WEBrick::HTTPServer.new(:Port => 8000,
|
|
# :SSLEnable => true,
|
|
# :SSLCertName => cert_name)
|
|
#
|
|
# This will start the server with a self-generated self-signed certificate.
|
|
# The certificate will be changed every time the server is restarted.
|
|
#
|
|
# To create a server with a pre-determined key and certificate you can provide
|
|
# them:
|
|
#
|
|
# require 'webrick'
|
|
# require 'webrick/https'
|
|
# require 'openssl'
|
|
#
|
|
# cert = OpenSSL::X509::Certificate.new File.read '/path/to/cert.pem'
|
|
# pkey = OpenSSL::PKey::RSA.new File.read '/path/to/pkey.pem'
|
|
#
|
|
# server = WEBrick::HTTPServer.new(:Port => 8000,
|
|
# :SSLEnable => true,
|
|
# :SSLCertificate => cert,
|
|
# :SSLPrivateKey => pkey)
|
|
#
|
|
# == Proxy Server
|
|
#
|
|
# WEBrick can act as a proxy server:
|
|
#
|
|
# require 'webrick'
|
|
# require 'webrick/httpproxy'
|
|
#
|
|
# proxy = WEBrick::HTTPProxyServer.new :Port => 8000
|
|
#
|
|
# trap 'INT' do proxy.shutdown end
|
|
#
|
|
# See WEBrick::HTTPProxy for further details including modifying proxied
|
|
# responses.
|
|
#
|
|
# == Basic and Digest authentication
|
|
#
|
|
# WEBrick provides both Basic and Digest authentication for regular and proxy
|
|
# servers. See WEBrick::HTTPAuth, WEBrick::HTTPAuth::BasicAuth and
|
|
# WEBrick::HTTPAuth::DigestAuth.
|
|
#
|
|
# == WEBrick as a Production Web Server
|
|
#
|
|
# WEBrick can be run as a production server for small loads.
|
|
#
|
|
# === Daemonizing
|
|
#
|
|
# To start a WEBrick server as a daemon simple run WEBrick::Daemon.start
|
|
# before starting the server.
|
|
#
|
|
# === Dropping Permissions
|
|
#
|
|
# WEBrick can be started as one user to gain permission to bind to port 80 or
|
|
# 443 for serving HTTP or HTTPS traffic then can drop these permissions for
|
|
# regular operation. To listen on all interfaces for HTTP traffic:
|
|
#
|
|
# sockets = WEBrick::Utils.create_listeners nil, 80
|
|
#
|
|
# Then drop privileges:
|
|
#
|
|
# WEBrick::Utils.su 'www'
|
|
#
|
|
# Then create a server that does not listen by default:
|
|
#
|
|
# server = WEBrick::HTTPServer.new :DoNotListen => true, # ...
|
|
#
|
|
# Then overwrite the listening sockets with the port 80 sockets:
|
|
#
|
|
# server.listeners.replace sockets
|
|
#
|
|
# === Logging
|
|
#
|
|
# WEBrick can separately log server operations and end-user access. For
|
|
# server operations:
|
|
#
|
|
# log_file = File.open '/var/log/webrick.log', 'a+'
|
|
# log = WEBrick::Log.new log_file
|
|
#
|
|
# For user access logging:
|
|
#
|
|
# access_log = [
|
|
# [log_file, WEBrick::AccessLog::COMBINED_LOG_FORMAT],
|
|
# ]
|
|
#
|
|
# server = WEBrick::HTTPServer.new :Logger => log, :AccessLog => access_log
|
|
#
|
|
# See WEBrick::AccessLog for further log formats.
|
|
#
|
|
# === Log Rotation
|
|
#
|
|
# To rotate logs in WEBrick on a HUP signal (like syslogd can send), open the
|
|
# log file in 'a+' mode (as above) and trap 'HUP' to reopen the log file:
|
|
#
|
|
# trap 'HUP' do log_file.reopen '/path/to/webrick.log', 'a+'
