|
# == An HTTP client API for Ruby.
|
|
#
|
|
# Net::HTTP provides a rich library which can be used to build HTTP
|
|
# user-agents. For more details about HTTP see
|
|
# [RFC2616](http://www.ietf.org/rfc/rfc2616.txt).
|
|
#
|
|
# Net::HTTP is designed to work closely with URI. URI::HTTP#host,
|
|
# URI::HTTP#port and URI::HTTP#request_uri are designed to work with
|
|
# Net::HTTP.
|
|
#
|
|
# If you are only performing a few GET requests you should try OpenURI.
|
|
#
|
|
# == Simple Examples
|
|
#
|
|
# All examples assume you have loaded Net::HTTP with:
|
|
#
|
|
# require 'net/http'
|
|
#
|
|
# This will also require 'uri' so you don't need to require it separately.
|
|
#
|
|
# The Net::HTTP methods in the following section do not persist
|
|
# connections. They are not recommended if you are performing many HTTP
|
|
# requests.
|
|
#
|
|
# === GET
|
|
#
|
|
# Net::HTTP.get('example.com', '/index.html') # => String
|
|
#
|
|
# === GET by URI
|
|
#
|
|
# uri = URI('http://example.com/index.html?count=10')
|
|
# Net::HTTP.get(uri) # => String
|
|
#
|
|
# === GET with Dynamic Parameters
|
|
#
|
|
# uri = URI('http://example.com/index.html')
|
|
# params = { :limit => 10, :page => 3 }
|
|
# uri.query = URI.encode_www_form(params)
|
|
#
|
|
# res = Net::HTTP.get_response(uri)
|
|
# puts res.body if res.is_a?(Net::HTTPSuccess)
|
|
#
|
|
# === POST
|
|
#
|
|
# uri = URI('http://www.example.com/search.cgi')
|
|
# res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
|
|
# puts res.body
|
|
#
|
|
# === POST with Multiple Values
|
|
#
|
|
# uri = URI('http://www.example.com/search.cgi')
|
|
# res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
|
|
# puts res.body
|
|
#
|
|
# == How to use Net::HTTP
|
|
#
|
|
# The following example code can be used as the basis of an HTTP user-agent
|
|
# which can perform a variety of request types using persistent
|
|
# connections.
|
|
#
|
|
# uri = URI('http://example.com/some_path?query=string')
|
|
#
|
|
# Net::HTTP.start(uri.host, uri.port) do |http|
|
|
# request = Net::HTTP::Get.new uri
|
|
#
|
|
# response = http.request request # Net::HTTPResponse object
|
|
# end
|
|
#
|
|
# Net::HTTP::start immediately creates a connection to an HTTP server which
|
|
# is kept open for the duration of the block. The connection will remain
|
|
# open for multiple requests in the block if the server indicates it
|
|
# supports persistent connections.
|
|
#
|
|
# If you wish to re-use a connection across multiple HTTP requests without
|
|
# automatically closing it you can use ::new and then call #start and
|
|
# #finish manually.
|
|
#
|
|
# The request types Net::HTTP supports are listed below in the section "HTTP
|
|
# Request Classes".
|
|
#
|
|
# For all the Net::HTTP request objects and shortcut request methods you may
|
|
# supply either a String for the request path or a URI from which Net::HTTP
|
|
# will extract the request path.
|
|
#
|
|
# === Response Data
|
|
#
|
|
# uri = URI('http://example.com/index.html')
|
|
# res = Net::HTTP.get_response(uri)
|
|
#
|
|
# # Headers
|
|
# res['Set-Cookie'] # => String
|
|
# res.get_fields('set-cookie') # => Array
|
|
# res.to_hash['set-cookie'] # => Array
|
|
# puts "Headers: #{res.to_hash.inspect}"
|
|
#
|
|
# # Status
|
|
# puts res.code # => '200'
|
|
# puts res.message # => 'OK'
|
|
# puts res.class.name # => 'HTTPOK'
|
|
#
|
|
# # Body
|
|
# puts res.body if res.response_body_permitted?
|
|
#
|
|
# === 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')
|
|
#
|
|
# === POST
|
|
#
|
|
# A POST can be made using the Net::HTTP::Post request class. This example
|
|
# creates a URL encoded POST body:
|
|
#
|
|
# uri = URI('http://www.example.com/todo.cgi')
|
|
# req = Net::HTTP::Post.new(uri)
|
|
# req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')
|
|
#
|
|
# res = Net::HTTP.start(uri.hostname, uri.port) do |http|
|
|
# http.request(req)
|
|
# end
|
|
#
|
|
# case res
|
|
# when Net::HTTPSuccess, Net::HTTPRedirection
|
|
# # OK
|
|
# else
|
|
# res.value
|
|
# end
|
|
#
|
|
# To send multipart/form-data use Net::HTTPHeader#set_form:
|
|
#
|
|
# req = Net::HTTP::Post.new(uri)
|
|
# req.set_form([['upload', File.open('foo.bar')]], 'multipart/form-data')
|
|
#
|
|
# Other requests that can contain a body such as PUT can be created in the
|
|
# same way using the corresponding request class (Net::HTTP::Put).
|
|
#
|
|
# === Setting Headers
|
|
#
|
|
# The following example performs a conditional GET using the
|
|
# If-Modified-Since header. If the files has not been modified since the
|
|
# time in the header a Not Modified response will be returned. See RFC 2616
|
|
# section 9.3 for further details.
|
|
#
|
|
# uri = URI('http://example.com/cached_response')
|
|
# file = File.stat 'cached_response'
|
|
#
|
|
# req = Net::HTTP::Get.new(uri)
|
|
# req['If-Modified-Since'] = file.mtime.rfc2822
|
|
#
|
|
# res = Net::HTTP.start(uri.hostname, uri.port) {|http|
|
|
# http.request(req)
|
|
# }
|
|
#
|
|
# open 'cached_response', 'w' do |io|
|
|
# io.write res.body
|
|
# end if res.is_a?(Net::HTTPSuccess)
|
|
#
|
|
# === 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.
|
|
#
|
|

#
|
|
# Here is the HTTP request class hierarchy.
|
|
#
|
|
