# == About the Examples
#
# :include: doc/net-http/examples.rdoc
#
# == URIs
#
# On the internet, a URI
# ({Universal Resource Identifier}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier])
# is a string that identifies a particular resource.
# It consists of some or all of: scheme, hostname, path, query, and fragment;
# see {URI syntax}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax].
#
# A Ruby {URI::Generic}[rdoc-ref:URI::Generic] object
# represents an internet URI.
# It provides, among others, methods
# +scheme+, +hostname+, +path+, +query+, and +fragment+.
#
# === Schemes
#
# An internet \URI has
# a {scheme}[https://en.wikipedia.org/wiki/List_of_URI_schemes].
#
# The two schemes supported in \Net::HTTP are <tt>'https'</tt> and <tt>'http'</tt>:
#
# uri.scheme # => "https"
# URI('http://example.com').scheme # => "http"
#
# === Hostnames
#
# A hostname identifies a server (host) to which requests may be sent:
#
# hostname = uri.hostname # => "jsonplaceholder.typicode.com"
# Net::HTTP.start(hostname) do |http|
# # Some HTTP stuff.
# end
#
# === Paths
#
# A host-specific path identifies a resource on the host:
#
# _uri = uri.dup
# _uri.path = '/todos/1'
# hostname = _uri.hostname
# path = _uri.path
# Net::HTTP.get(hostname, path)
#
# === Queries
#
# A host-specific query adds name/value pairs to the URI:
#
# _uri = uri.dup
# params = {userId: 1, completed: false}
# _uri.query = URI.encode_www_form(params)
# _uri # => #<URI::HTTPS https://jsonplaceholder.typicode.com?userId=1&completed=false>
# Net::HTTP.get(_uri)
#
# === Fragments
#
# A {URI fragment}[https://en.wikipedia.org/wiki/URI_fragment] has no effect
# in \Net::HTTP;
# the same data is returned, regardless of whether a fragment is included.
#
# == Request Headers
#
# Request headers may be used to pass additional information to the host,
# similar to arguments passed in a method call;
# each header is a name/value pair.
#
# Each of the \Net::HTTP methods that sends a request to the host
# has optional argument +headers+,
# where the headers are expressed as a hash of field-name/value pairs:
#
# headers = {Accept: 'application/json', Connection: 'Keep-Alive'}
# Net::HTTP.get(uri, headers)
#
# See lists of both standard request fields and common request fields at
# {Request Fields}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Request_fields].
# A host may also accept other custom fields.
#
# == Sessions
#
# A _session_ is a connection between a server (host) and a client that:
#
# - Is begun by instance method Net::HTTP#start.
# - May contain any number of requests.
# - Is ended by instance method Net::HTTP#finish.
#
# See example sessions at the {Synopsis}[rdoc-ref:Net::HTTP@Synopsis].
#
# === Session Using \Net::HTTP.start
#
# If you have many requests to make to a single host (and port),
# consider using singleton method Net::HTTP.start with a block;
# the method handles the session automatically by:
#
# - Calling #start before block execution.
# - Executing the block.
# - Calling #finish after block execution.
#
# In the block, you can use these instance methods,
# each of which that sends a single request:
#
# - {HTTP methods}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods]:
#
# - #get, #request_get: GET.
# - #head, #request_head: HEAD.
# - #post, #request_post: POST.
# - #delete: DELETE.
# - #options: OPTIONS.
# - #trace: TRACE.
# - #patch: PATCH.
#
# - {WebDAV methods}[https://en.wikipedia.org/wiki/WebDAV#Implementation]:
#
# - #copy: COPY.
# - #lock: LOCK.
# - #mkcol: MKCOL.
# - #move: MOVE.
# - #propfind: PROPFIND.
# - #proppatch: PROPPATCH.
# - #unlock: UNLOCK.
#
# === Session Using \Net::HTTP.start and \Net::HTTP.finish
#
# You can manage a session manually using methods #start and #finish:
#
# http = Net::HTTP.new(hostname)
# http.start
# http.get('/todos/1')
# http.get('/todos/2')
# http.delete('/posts/1')
# http.finish # Needed to free resources.
#
# === Single-Request Session
#
# Certain convenience methods automatically handle a session by:
#
# - Creating an \HTTP object
# - Starting a session.
# - Sending a single request.
# - Finishing the session.
# - Destroying the object.
#
# Such methods that send GET requests:
#
# - ::get: Returns the string response body.
# - ::get_print: Writes the string response body to $stdout.
# - ::get_response: Returns a Net::HTTPResponse object.
#
# Such methods that send POST requests:
#
# - ::post: Posts data to the host.
# - ::post_form: Posts form data to the host.
#
# == \HTTP Requests and Responses
#
# Many of the methods above are convenience methods,
# each of which sends a request and returns a string
# without directly using \Net::HTTPRequest and \Net::HTTPResponse objects.
#
# You can, however, directly create a request object, send the request,
# and retrieve the response object; see:
#
# - Net::HTTPRequest.
# - Net::HTTPResponse.
#
# == Following Redirection
#
# Each Net::HTTPResponse object belongs to a class for its response code.
#
# For example, all 2XX responses are instances of a Net::HTTPSuccess
# subclass, a 3XX response is an instance of a Net::HTTPRedirection
# subclass and a 200 response is an instance of the Net::HTTPOK class. For
# details of response classes, see the section "HTTP Response Classes"
# below.
#
# Using a case statement you can handle various types of responses properly:
#
# def fetch(uri_str, limit = 10)
# # You should choose a better exception.
# raise ArgumentError, 'too many HTTP redirects' if limit == 0
#
# response = Net::HTTP.get_response(URI(uri_str))
#
# case response
# when Net::HTTPSuccess then
# response
# when Net::HTTPRedirection then
# location = response['location']
# warn "redirected to #{location}"
# fetch(location, limit - 1)
# else
# response.value
# end
# end
#
# print fetch('http://www.ruby-lang.org')
#
# == Basic Authentication
#
# Basic authentication is performed according to
# [RFC2617](http://www.ietf.org/rfc/rfc2617.txt).
#
# uri = URI('http://example.com/index.html?key=value')
#
# req = Net::HTTP::Get.new(uri)
# req.basic_auth 'user', 'pass'
#
# res = Net::HTTP.start(uri.hostname, uri.port) {|http|
# http.request(req)
# }
# puts res.body
#
# == Streaming Response Bodies
#
# By default Net::HTTP reads an entire response into memory. If you are
# handling large files or wish to implement a progress bar you can instead
# stream the body directly to an IO.
#
# uri = URI('http://example.com/large_file')
#
# Net::HTTP.start(uri.host, uri.port) do |http|
# request = Net::HTTP::Get.new uri
#
# http.request request do |response|
# open 'large_file', 'w' do |io|
# response.read_body do |chunk|
# io.write chunk
# end
# end
# end
# end
#
# == HTTPS
#
# HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=.
#
# uri = URI('https://secure.example.com/some_path?query=string')
#
# Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
# request = Net::HTTP::Get.new uri
# response = http.request request # Net::HTTPResponse object
# end
#
# Or if you simply want to make a GET request, you may pass in an URI
# object that has an HTTPS URL. Net::HTTP automatically turns on TLS
# verification if the URI object has a 'https' URI scheme.
#
# uri = URI('https://example.com/')
# Net::HTTP.get(uri) # => String
#
# In previous versions of Ruby you would need to require 'net/https' to use
# HTTPS. This is no longer true.
#
# == Proxies
#
# Net::HTTP will automatically create a proxy from the +http_proxy+
# environment variable if it is present. To disable use of +http_proxy+,
# pass +nil+ for the proxy address.
#
# You may also create a custom proxy:
#
# proxy_addr = 'your.proxy.host'
# proxy_port = 8080
#
# Net::HTTP.new('example.com', nil, proxy_addr, proxy_port).start { |http|
# # always proxy via your.proxy.addr:8080
# }
#
# See Net::HTTP.new for further details and examples such as proxies that
# require a username and password.
#
# == Compression
#
# Net::HTTP automatically adds Accept-Encoding for compression of response
# bodies and automatically decompresses gzip and deflate responses unless a
# Range header was sent.
#
# Compression can be disabled through the Accept-Encoding: identity header.
