# == 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
|
|
# :
|
|
# }
|
|
#
|
|
# Note that net/http never rely on HTTP_PROXY environment variable.
|
|
# If you want to use proxy, set it explicitly.
|
|
#
|
|
# === 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".
|
|
#
|
|
# === Basic Authentication
|
|
#
|
|
# require 'net/http'
|
|
#
|
|
# Net::HTTP.start('www.example.com') {|http|
|
|
# req = Net::HTTP::Get.new('/secret-page.html')
|
|
# req.basic_auth 'account', 'password'
|
|
# response = http.request(req)
|
|
# print response.body
|
|
# }
|
|
#
|
|
# === HTTP Response Classes
|
|
#
|
|
# TODO: write me.
|
|
#
|
|
# == Switching Net::HTTP versions
|
|
#
|
|
# You can use net/http.rb 1.1 features (bundled with Ruby 1.6)
|
|
# by calling HTTP.version_1_1. Calling Net::HTTP.version_1_2
|
|
# allows you to use 1.2 features again.
|
|
#
|
|
# # example
|
|
# Net::HTTP.start { |http1| ...(http1 has 1.2 features)... }
|
|
#
|
|
# Net::HTTP.version_1_1
|
|
# Net::HTTP.start { |http2| ...(http2 has 1.1 features)... }
|
|
#
|
|
# Net::HTTP.version_1_2
|
|
# Net::HTTP.start { |http3| ...(http3 has 1.2 features)... }
|

#
|
|
# This function is NOT thread-safe.
