# == What Is This Library?
|
||||
#
|
||||
# This library provides your program functions to access WWW
|
||||
# documents via HTTP, Hyper Text Transfer Protocol version 1.1.
|
||||
# For details of HTTP, refer [RFC2616]
|
||||
# ((<URL:http://www.ietf.org/rfc/rfc2616.txt>)).
|
||||
#
|
||||
# == Examples
|
||||
#
|
||||
# === Getting Document From WWW Server
|
||||
#
|
||||
# (formal version)
|
||||
#
|
||||
# require 'net/http'
|
||||
# Net::HTTP.start('www.example.com', 80) {|http|
|
||||
# response = http.get('/index.html')
|
||||
# puts response.body
|
||||
# }
|
||||
#
|
||||
# (shorter version)
|
||||
#
|
||||
# require 'net/http'
|
||||
# Net::HTTP.get_print 'www.example.com', '/index.html'
|
||||
#
|
||||
# or
|
||||
#
|
||||
# require 'net/http'
|
||||
# require 'uri'
|
||||
# Net::HTTP.get_print URI.parse('http://www.example.com/index.html')
|
||||
#
|
||||
# === Posting Form Data
|
||||
#
|
||||
# require 'net/http'
|
||||
# Net::HTTP.start('some.www.server', 80) {|http|
|
||||
# response = http.post('/cgi-bin/search.rb', 'query=ruby')
|
||||
# }
|
||||
#
|
||||
# === Accessing via Proxy
|
||||
#
|
||||
# Net::HTTP.Proxy creates http proxy class. It has same
|
||||
# methods of Net::HTTP but its instances always connect to
|
||||
# proxy, instead of given host.
|
||||
#
|
||||
# require 'net/http'
|
||||
#
|
||||
# proxy_addr = 'your.proxy.host'
|
||||
# proxy_port = 8080
|
||||
# :
|
||||
# Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com') {|http|
|
||||
# # always connect to your.proxy.addr:8080
|
||||
# :
|
||||
# }
|
||||
#
|
||||
# Since Net::HTTP.Proxy returns Net::HTTP itself when proxy_addr is nil,
|
||||
# there's no need to change code if there's proxy or not.
|
||||
#
|
||||
# There are two additional parameters in Net::HTTP.Proxy which allow to
|
||||
# specify proxy user name and password:
|
||||
#
|
||||
# Net::HTTP::Proxy(proxy_addr, proxy_port, proxy_user = nil, proxy_pass = nil)
|
||||
#
|
||||
# You may use them to work with authorization-enabled proxies:
|
||||
#
|
||||
# require 'net/http'
|
||||
# require 'uri'
|
||||
#
|
||||
# proxy_host = 'your.proxy.host'
|
||||
# proxy_port = 8080
|
||||
# uri = URI.parse(ENV['http_proxy'])
|
||||
# proxy_user, proxy_pass = uri.userinfo.split(/:/) if uri.userinfo
|
||||
# Net::HTTP::Proxy(proxy_host, proxy_port,
|
||||
# proxy_user, proxy_pass).start('www.example.com') {|http|
|
||||
# # always connect to your.proxy.addr:8080 using specified username and password
|
||||
# :
|
||||
# }
|
||||
#
|
||||
#
|
||||
# === Following Redirection
|
||||
#
|
||||
# require 'net/http'
|
||||
# require 'uri'
|
||||
#
|
||||
# def fetch( uri_str, limit = 10 )
|
||||
# # You should choose better exception.
|
||||
# raise ArgumentError, 'http redirect too deep' if limit == 0
|
||||
#
|
||||
# response = Net::HTTP.get_response(URI.parse(uri_str))
|
||||
# case response
|
||||
# when Net::HTTPSuccess then response
|
||||
# when Net::HTTPRedirection then fetch(response['location'], limit - 1)
|
||||
# else
|
||||
# response.error!
|
||||
# end
|
||||
# end
|
||||
#
|
||||
# print fetch('http://www.ruby-lang.org')
|
||||
#
|
||||
# Net::HTTPSuccess and Net::HTTPRedirection is a HTTPResponse class.
|
||||
# All HTTPResponse objects belong to its own response class which
|
||||
# indicate HTTP result status. For details of response classes,
|
||||
# see section "HTTP Response Classes".

||||
# require 'net/http'

# == IMAP OVERVIEW
|
||||
# Documentation: Shugo Maeda, with RDoc conversion and overview by William
|
||||
# Webber.
|
||||
#
|
||||
# An IMAP client connects to a server, and then authenticates
|
||||
# itself using either #authenticate() or #login(). Having
|
||||
# authenticated itself, there is a range of commands
|
||||
# available to it. Most work with mailboxes, which may be
|
||||
# arranged in an hierarchical namespace, and each of which
|
||||
# contains zero or more messages. How this is implemented on
|
||||
# the server is implementation-dependent; on a UNIX server, it
|
||||
# will frequently be implemented as a files in mailbox format
|
||||
# within a hierarchy of directories.
|
||||
#
|
||||
# To work on the messages within a mailbox, the client must
|
||||
# first select that mailbox, using either #select() or (for
|
||||
# read-only access) #examine(). Once the client has successfully
|
||||
# selected a mailbox, they enter _selected_ state, and that
|
||||
# mailbox becomes the _current_ mailbox, on which mail-item
|
||||
# related commands implicitly operate.
|
||||
#
|
||||
# Messages have two sorts of identifiers: message sequence
|
||||
# numbers, and UIDs.
|
||||
#
|
||||
# Message sequence numbers number messages within a mail box
|
||||
# from 1 up to the number of items in the mail box. If new
|
||||
# message arrives during a session, it receives a sequence
|
||||
# number equal to the new size of the mail box. If messages
|
||||
# are expunged from the mailbox, remaining messages have their
|
||||
# sequence numbers "shuffled down" to fill the gaps.
|
||||
#
|
||||
# UIDs, on the other hand, are permanently guaranteed not to
|
||||
# identify another message within the same mailbox, even if
|
||||
# the existing message is deleted. UIDs are required to
|
||||
# be assigned in ascending (but not necessarily sequential)
|
||||
# order within a mailbox; this means that if a non-IMAP client
|
||||
# rearranges the order of mailitems within a mailbox, the
|
||||
# UIDs have to be reassigned. An IMAP client cannot thus
|
||||
# rearrange message orders.
|
||||
#
|
||||
# == EXAMPLES OF USAGE
|
||||
#
|
||||
# === List sender and subject of all recent messages in the default mailbox
|
||||
#
|
||||
# imap = Net::IMAP.new('mail.example.com')
|
||||
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
|
||||
# imap.examine('INBOX')
|
||||
# imap.search(["RECENT"]).each do |message_id|
|
||||
# envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
|
||||
# puts "#{envelope.from[0].name}: \t#{envelope.subject}"
|
||||
# end
|
||||
#
|
||||
# === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"
|
||||
#
|
||||
# imap = Net::IMAP.new('mail.example.com')
|
||||
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
|
||||
# imap.select('Mail/sent-mail')
|
||||
# if not imap.list('Mail/', 'sent-apr03')
|
||||
# imap.create('Mail/sent-apr03')
|
||||
# end
|
||||
# imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
|
||||
# imap.copy(message_id, "Mail/sent-apr03")
|
||||
# imap.store(message_id, "+FLAGS", [:Deleted])
|
||||
# end
|
||||
# imap.expunge
|
||||
#
|
||||
# == THREAD-SAFENESS
|
||||
#
|
||||
# Net::IMAP supports concurrent threads. For example,
|
||||
#
|
||||
# imap = Net::IMAP.new("imap.foo.net", "imap2")
|
||||
# imap.authenticate("cram-md5", "bar", "password")
|
||||
# imap.select("inbox")
|
||||
# fetch_thread = Thread.start { imap.fetch(1..-1, "UID") }
|
||||
# search_result = imap.search(["BODY", "hello"])
|
||||
# fetch_result = fetch_thread.value
|
||||
# imap.disconnect
|
||||
#
|
||||
# This script invokes the FETCH command and the SEARCH command concurrently.
|
||||
#
|
||||
# == ERRORS
|
||||
#
|
||||
# An IMAP server can send three different types of responses to indicate
|
||||
# failure:
|
||||
#
|
||||
# NO:: the attempted command could not be successfully completed. For
|
||||
# instance, the username/password used for logging in are incorrect;
|
||||
# the selected mailbox does not exists; etc.
|
||||
#
|
||||
# BAD:: the request from the client does not follow the server's
|
||||
# understanding of the IMAP protocol. This includes attempting
|
||||
# commands from the wrong client state; for instance, attempting
|
||||
# to perform a SEARCH command without having SELECTed a current
|
||||
# mailbox. It can also signal an internal server
|
||||
# failure (such as a disk crash) has occurred.
|
||||
#
|
||||
# BYE:: the server is saying goodbye. This can be part of a normal
|
||||
# logout sequence, and can be used as part of a login sequence
|
||||
# to indicate that the server is (for some reason) unwilling
|
||||
# to accept our connection. As a response to any other command,
|
||||
# it indicates either that the server is shutting down, or that
|
||||
# the server is timing out the client connection due to inactivity.
|
||||
#
|
||||
# These three error response are represented by the errors
|
||||
# Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and
|
||||
# Net::IMAP::ByeResponseError, all of which are subclasses of
|
||||
# Net::IMAP::ResponseError. Essentially, all methods that involve
|
||||
# sending a request to the server can generate one of these errors.

|
||||
|
||||
#
|
||||
# Net::IMAP implements Internet Message Access Protocol (IMAP) client
|
||||
# functionality. The protocol is described in [IMAP].
|
||||
#
|
||||
# See comment to the file imap.rb for examples of usage.
|
||||
# == IMAP OVERVIEW
|
||||
#
|
||||
# An IMAP client connects to a server, and then authenticates
|
||||
# itself using either #authenticate() or #login(). Having
|
||||
# authenticated itself, there is a range of commands
|
||||
# available to it. Most work with mailboxes, which may be
|
||||
# arranged in an hierarchical namespace, and each of which
|
||||
# contains zero or more messages. How this is implemented on
|
||||
# the server is implementation-dependent; on a UNIX server, it
|
||||
# will frequently be implemented as a files in mailbox format
|
||||
# within a hierarchy of directories.
|
||||
#
|
||||
# To work on the messages within a mailbox, the client must
|
||||
# first select that mailbox, using either #select() or (for
|
||||
# read-only access) #examine(). Once the client has successfully
|
||||
# selected a mailbox, they enter _selected_ state, and that
|
||||
# mailbox becomes the _current_ mailbox, on which mail-item
|
||||
# related commands implicitly operate.
|
||||
#
|
||||
# Messages have two sorts of identifiers: message sequence
|
||||
# numbers, and UIDs.
|
||||
#
|
||||
# Message sequence numbers number messages within a mail box
|
||||
# from 1 up to the number of items in the mail box. If new
|
||||
# message arrives during a session, it receives a sequence
|
||||
# number equal to the new size of the mail box. If messages
|
||||
# are expunged from the mailbox, remaining messages have their
|
||||
# sequence numbers "shuffled down" to fill the gaps.
|
||||
#
|
||||
# UIDs, on the other hand, are permanently guaranteed not to
|
||||
# identify another message within the same mailbox, even if
|
||||
# the existing message is deleted. UIDs are required to
|
||||
# be assigned in ascending (but not necessarily sequential)
|
||||
# order within a mailbox; this means that if a non-IMAP client
|
||||
# rearranges the order of mailitems within a mailbox, the
|
||||
# UIDs have to be reassigned. An IMAP client cannot thus
|
||||
# rearrange message orders.
|
||||
#
|
||||
# == EXAMPLES OF USAGE
|
||||
#
|
||||
# === List sender and subject of all recent messages in the default mailbox
|
||||
#
|
||||
# imap = Net::IMAP.new('mail.example.com')
|
||||
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
|
||||
# imap.examine('INBOX')
|
||||
# imap.search(["RECENT"]).each do |message_id|
|
||||
# envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
|
||||
# puts "#{envelope.from[0].name}: \t#{envelope.subject}"
|
||||
# end
|
||||
#
|
||||
# === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"
|
||||
#
|
||||
# imap = Net::IMAP.new('mail.example.com')
|
||||
# imap.authenticate('LOGIN', 'joe_user', 'joes_password')
|
||||
# imap.select('Mail/sent-mail')
|
||||
# if not imap.list('Mail/', 'sent-apr03')
|
||||
# imap.create('Mail/sent-apr03')
|
||||
# end
|
||||
# imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
|
||||
# imap.copy(message_id, "Mail/sent-apr03")
|
||||
# imap.store(message_id, "+FLAGS", [:Deleted])
|
||||
# end
|
||||
# imap.expunge
|
||||
#
|
||||
# == THREAD-SAFENESS
|
||||
#
|
||||
# Net::IMAP supports concurrent threads. For example,
|
||||
#
|
||||
# imap = Net::IMAP.new("imap.foo.net", "imap2")
|
||||
# imap.authenticate("cram-md5", "bar", "password")
|
||||
# imap.select("inbox")
|
||||
# fetch_thread = Thread.start { imap.fetch(1..-1, "UID") }
|
||||
# search_result = imap.search(["BODY", "hello"])
|
||||
# fetch_result = fetch_thread.value
|
||||
# imap.disconnect
|
||||
#
|
||||
# This script invokes the FETCH command and the SEARCH command concurrently.
|
||||
#
|
||||
# == ERRORS
|
||||
#
|
||||
# An IMAP server can send three different types of responses to indicate
|
||||
# failure:
|
||||
#
|
||||
# NO:: the attempted command could not be successfully completed. For
|
||||
# instance, the username/password used for logging in are incorrect;
|
||||
# the selected mailbox does not exists; etc.
|
||||
#
|
||||
# BAD:: the request from the client does not follow the server's
|
||||
# understanding of the IMAP protocol. This includes attempting
|
||||
# commands from the wrong client state; for instance, attempting
|
||||
# to perform a SEARCH command without having SELECTed a current
|
||||
# mailbox. It can also signal an internal server
|
||||
# failure (such as a disk crash) has occurred.
|
||||
#
|
||||
# BYE:: the server is saying goodbye. This can be part of a normal
|
||||
# logout sequence, and can be used as part of a login sequence
|
||||
# to indicate that the server is (for some reason) unwilling
|
||||
# to accept our connection. As a response to any other command,
|
||||
# it indicates either that the server is shutting down, or that
|
||||
# the server is timing out the client connection due to inactivity.
|
||||
#
|
||||
# These three error response are represented by the errors
|
||||
# Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and
|
||||
# Net::IMAP::ByeResponseError, all of which are subclasses of
|
||||
# Net::IMAP::ResponseError. Essentially, all methods that involve
|
||||
# sending a request to the server can generate one of these errors.
|
||||
# Only the most pertinent instances have been documented below.
|
||||
#
|
||||
# Because the IMAP class uses Sockets for communication, its methods
|
||||
# are also susceptible to the various errors that can occur when
|
||||
# working with sockets. These are generally represented as
|
||||
# Errno errors. For instance, any method that involves sending a
|
||||
# request to the server and/or receiving a response from it could
|
||||

# goes down. See the socket(7), ip(7), tcp(7), socket(2), connect(2),
|
||||
# and associated man pages.
|
||||
#
|

# Finally, a Net::IMAP::DataFormatError is thrown if low-level data
|
||||
# is found to be in an incorrect format (for instance, when converting
|
||||
# between UTF-8 and UTF-16), and Net::IMAP::ResponseParseError is
|
||||
# thrown if a server response is non-parseable.
