# = WEB server toolkit.

[2] Fix | Delete

[3] Fix | Delete

# WEBrick is an HTTP server toolkit that can be configured as an HTTPS server,

[4] Fix | Delete

# a proxy server, and a virtual-host server. WEBrick features complete

[5] Fix | Delete

# logging of both server operations and HTTP access. WEBrick supports both

[6] Fix | Delete

# basic and digest authentication in addition to algorithms not in RFC 2617.

[7] Fix | Delete

[8] Fix | Delete

# A WEBrick server can be composed of multiple WEBrick servers or servlets to

[9] Fix | Delete

# provide differing behavior on a per-host or per-path basis. WEBrick

[10] Fix | Delete

# includes servlets for handling CGI scripts, ERB pages, Ruby blocks and

[11] Fix | Delete

# directory listings.

[12] Fix | Delete

[13] Fix | Delete

# WEBrick also includes tools for daemonizing a process and starting a process

[14] Fix | Delete

# at a higher privilege level and dropping permissions.

[15] Fix | Delete

[16] Fix | Delete

# == Starting an HTTP server

[17] Fix | Delete

[18] Fix | Delete

# To create a new WEBrick::HTTPServer that will listen to connections on port

[19] Fix | Delete

# 8000 and serve documents from the current user's public_html folder:

[20] Fix | Delete

[21] Fix | Delete

# require 'webrick'

[22] Fix | Delete

[23] Fix | Delete

# root = File.expand_path '~/public_html'

[24] Fix | Delete

# server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => root

[25] Fix | Delete

[26] Fix | Delete

# To run the server you will need to provide a suitable shutdown hook as

[27] Fix | Delete

# starting the server blocks the current thread:

[28] Fix | Delete

[29] Fix | Delete

# trap 'INT' do server.shutdown end

[30] Fix | Delete

[31] Fix | Delete

# server.start

[32] Fix | Delete

[33] Fix | Delete

# == Custom Behavior

[34] Fix | Delete

[35] Fix | Delete

# The easiest way to have a server perform custom operations is through

[36] Fix | Delete

# WEBrick::HTTPServer#mount_proc. The block given will be called with a

[37] Fix | Delete

# WEBrick::HTTPRequest with request info and a WEBrick::HTTPResponse which

[38] Fix | Delete

# must be filled in appropriately:

[39] Fix | Delete

[40] Fix | Delete

# server.mount_proc '/' do |req, res|

[41] Fix | Delete

# res.body = 'Hello, world!'

[42] Fix | Delete

# end

[43] Fix | Delete

[44] Fix | Delete

# Remember that +server.mount_proc+ must precede +server.start+.

[45] Fix | Delete

[46] Fix | Delete

# == Servlets

[47] Fix | Delete

[48] Fix | Delete

# Advanced custom behavior can be obtained through mounting a subclass of

[49] Fix | Delete

# WEBrick::HTTPServlet::AbstractServlet. Servlets provide more modularity

[50] Fix | Delete

# when writing an HTTP server than mount_proc allows. Here is a simple

[51] Fix | Delete

# servlet:

[52] Fix | Delete

[53] Fix | Delete

# class Simple < WEBrick::HTTPServlet::AbstractServlet

[54] Fix | Delete

# def do_GET request, response

[55] Fix | Delete

# status, content_type, body = do_stuff_with request

[56] Fix | Delete

[57] Fix | Delete

# response.status = 200

[58] Fix | Delete

# response['Content-Type'] = 'text/plain'

[59] Fix | Delete

# response.body = 'Hello, World!'

[60] Fix | Delete

# end

[61] Fix | Delete

# end

[62] Fix | Delete

[63] Fix | Delete

# To initialize the servlet you mount it on the server:

[64] Fix | Delete

[65] Fix | Delete

# server.mount '/simple', Simple

[66] Fix | Delete

[67] Fix | Delete

# See WEBrick::HTTPServlet::AbstractServlet for more details.

[68] Fix | Delete

[69] Fix | Delete

# == Virtual Hosts

[70] Fix | Delete

[71] Fix | Delete

# A server can act as a virtual host for multiple host names. After creating

[72] Fix | Delete

# the listening host, additional hosts that do not listen can be created and

[73] Fix | Delete

# attached as virtual hosts:

[74] Fix | Delete

[75] Fix | Delete

# server = WEBrick::HTTPServer.new # ...

[76] Fix | Delete

[77] Fix | Delete

# vhost = WEBrick::HTTPServer.new :ServerName => 'vhost.example',

[78] Fix | Delete

# :DoNotListen => true, # ...

[79] Fix | Delete

# vhost.mount '/', ...

[80] Fix | Delete

[81] Fix | Delete

# server.virtual_host vhost

[82] Fix | Delete

[83] Fix | Delete

# If no +:DocumentRoot+ is provided and no servlets or procs are mounted on the

[84] Fix | Delete

# main server it will return 404 for all URLs.

[85] Fix | Delete

[86] Fix | Delete

# == HTTPS

[87] Fix | Delete

[88] Fix | Delete

# To create an HTTPS server you only need to enable SSL and provide an SSL

[89] Fix | Delete

# certificate name:

[90] Fix | Delete

[91] Fix | Delete

# require 'webrick'

[92] Fix | Delete

# require 'webrick/https'

[93] Fix | Delete

[94] Fix | Delete

# cert_name = [

[95] Fix | Delete

# %w[CN localhost],

[96] Fix | Delete

# ]

[97] Fix | Delete

[98] Fix | Delete

# server = WEBrick::HTTPServer.new(:Port => 8000,

[99] Fix | Delete

# :SSLEnable => true,

[100] Fix | Delete

# :SSLCertName => cert_name)

[101] Fix | Delete

[102] Fix | Delete

# This will start the server with a self-generated self-signed certificate.

[103] Fix | Delete

# The certificate will be changed every time the server is restarted.

[104] Fix | Delete

[105] Fix | Delete

# To create a server with a pre-determined key and certificate you can provide

[106] Fix | Delete

# them:

[107] Fix | Delete

[108] Fix | Delete

# require 'webrick'

[109] Fix | Delete

# require 'webrick/https'

[110] Fix | Delete

# require 'openssl'

[111] Fix | Delete

[112] Fix | Delete

# cert = OpenSSL::X509::Certificate.new File.read '/path/to/cert.pem'

[113] Fix | Delete

# pkey = OpenSSL::PKey::RSA.new File.read '/path/to/pkey.pem'

[114] Fix | Delete

[115] Fix | Delete

# server = WEBrick::HTTPServer.new(:Port => 8000,

[116] Fix | Delete

# :SSLEnable => true,

[117] Fix | Delete

# :SSLCertificate => cert,

[118] Fix | Delete

# :SSLPrivateKey => pkey)

[119] Fix | Delete

[120] Fix | Delete

# == Proxy Server

[121] Fix | Delete

[122] Fix | Delete

# WEBrick can act as a proxy server:

[123] Fix | Delete

[124] Fix | Delete

# require 'webrick'

[125] Fix | Delete

# require 'webrick/httpproxy'

[126] Fix | Delete

[127] Fix | Delete

# proxy = WEBrick::HTTPProxyServer.new :Port => 8000

[128] Fix | Delete

[129] Fix | Delete

# trap 'INT' do proxy.shutdown end

[130] Fix | Delete

[131] Fix | Delete

# See WEBrick::HTTPProxy for further details including modifying proxied

[132] Fix | Delete

# responses.

[133] Fix | Delete

[134] Fix | Delete

# == Basic and Digest authentication

[135] Fix | Delete

[136] Fix | Delete

# WEBrick provides both Basic and Digest authentication for regular and proxy

[137] Fix | Delete

# servers. See WEBrick::HTTPAuth, WEBrick::HTTPAuth::BasicAuth and

[138] Fix | Delete

# WEBrick::HTTPAuth::DigestAuth.

[139] Fix | Delete

[140] Fix | Delete

# == WEBrick as a Production Web Server

[141] Fix | Delete

[142] Fix | Delete

# WEBrick can be run as a production server for small loads.

[143] Fix | Delete

[144] Fix | Delete

# === Daemonizing

[145] Fix | Delete

[146] Fix | Delete

# To start a WEBrick server as a daemon simple run WEBrick::Daemon.start

[147] Fix | Delete

# before starting the server.

[148] Fix | Delete

[149] Fix | Delete

# === Dropping Permissions

[150] Fix | Delete

[151] Fix | Delete

# WEBrick can be started as one user to gain permission to bind to port 80 or

[152] Fix | Delete

# 443 for serving HTTP or HTTPS traffic then can drop these permissions for

[153] Fix | Delete

# regular operation. To listen on all interfaces for HTTP traffic:

[154] Fix | Delete

[155] Fix | Delete

# sockets = WEBrick::Utils.create_listeners nil, 80

[156] Fix | Delete

[157] Fix | Delete

# Then drop privileges:

[158] Fix | Delete

[159] Fix | Delete

# WEBrick::Utils.su 'www'

[160] Fix | Delete

[161] Fix | Delete

# Then create a server that does not listen by default:

[162] Fix | Delete

[163] Fix | Delete

# server = WEBrick::HTTPServer.new :DoNotListen => true, # ...

[164] Fix | Delete

[165] Fix | Delete

# Then overwrite the listening sockets with the port 80 sockets:

[166] Fix | Delete

[167] Fix | Delete

# server.listeners.replace sockets

[168] Fix | Delete

[169] Fix | Delete

# === Logging

[170] Fix | Delete

[171] Fix | Delete

# WEBrick can separately log server operations and end-user access. For

[172] Fix | Delete

# server operations:

[173] Fix | Delete

[174] Fix | Delete

# log_file = File.open '/var/log/webrick.log', 'a+'

[175] Fix | Delete

# log = WEBrick::Log.new log_file

[176] Fix | Delete

[177] Fix | Delete

# For user access logging:

[178] Fix | Delete

[179] Fix | Delete

# access_log = [

[180] Fix | Delete

# [log_file, WEBrick::AccessLog::COMBINED_LOG_FORMAT],

[181] Fix | Delete

# ]

[182] Fix | Delete

[183] Fix | Delete

# server = WEBrick::HTTPServer.new :Logger => log, :AccessLog => access_log

[184] Fix | Delete

[185] Fix | Delete

# See WEBrick::AccessLog for further log formats.

[186] Fix | Delete

[187] Fix | Delete

# === Log Rotation

[188] Fix | Delete

[189] Fix | Delete

# To rotate logs in WEBrick on a HUP signal (like syslogd can send), open the

[190] Fix | Delete

# log file in 'a+' mode (as above) and trap 'HUP' to reopen the log file:

[191] Fix | Delete

[192] Fix | Delete

# trap 'HUP' do log_file.reopen '/path/to/webrick.log', 'a+'
