# \Class \Net::HTTP provides a rich library that implements the client
|
|
# in a client-server model that uses the \HTTP request-response protocol.
|
|
# For information about \HTTP, see:
|
|
#
|
|
# - {Hypertext Transfer Protocol}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol].
|
|
# - {Technical overview}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Technical_overview].
|
|
#
|
|
# == About the Examples
|
|
#
|
|
# :include: doc/net-http/examples.rdoc
|
|
#
|
|
# == Strategies
|
|
#
|
|
# - If you will make only a few GET requests,
|
|
# consider using {OpenURI}[rdoc-ref:OpenURI].
|
|
# - If you will make only a few requests of all kinds,
|
|
# consider using the various singleton convenience methods in this class.
|
|
# Each of the following methods automatically starts and finishes
|
|
# a {session}[rdoc-ref:Net::HTTP@Sessions] that sends a single request:
|
|
#
|
|
# # Return string response body.
|
|
# Net::HTTP.get(hostname, path)
|
|
# Net::HTTP.get(uri)
|
|
#
|
|
# # Write string response body to $stdout.
|
|
# Net::HTTP.get_print(hostname, path)
|
|
# Net::HTTP.get_print(uri)
|
|
#
|
|
# # Return response as Net::HTTPResponse object.
|
|
# Net::HTTP.get_response(hostname, path)
|
|
# Net::HTTP.get_response(uri)
|
|
# data = '{"title": "foo", "body": "bar", "userId": 1}'
|
|
# Net::HTTP.post(uri, data)
|
|
# params = {title: 'foo', body: 'bar', userId: 1}
|
|
# Net::HTTP.post_form(uri, params)
|
|
#
|
|
# - If performance is important, consider using sessions, which lower request overhead.
|
|
# This {session}[rdoc-ref:Net::HTTP@Sessions] has multiple requests for
|
|
# {HTTP methods}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods]
|
|
# and {WebDAV methods}[https://en.wikipedia.org/wiki/WebDAV#Implementation]:
|
|
#
|
|
# Net::HTTP.start(hostname) do |http|
|
|
# # Session started automatically before block execution.
|
|
# http.get(path)
|
|
# http.head(path)
|
|
# body = 'Some text'
|
|
# http.post(path, body) # Can also have a block.
|
|
# http.put(path, body)
|
|
# http.delete(path)
|
|
# http.options(path)
|
|
# http.trace(path)
|
|
# http.patch(path, body) # Can also have a block.
|
|
# http.copy(path)
|
|
# http.lock(path, body)
|
|
# http.mkcol(path, body)
|
|
# http.move(path)
|
|
# http.propfind(path, body)
|
|
# http.proppatch(path, body)
|
|
# http.unlock(path, body)
|
|
# # Session finished automatically at block exit.
|
|
# end
|
|
#
|
|
# The methods cited above are convenience methods that, via their few arguments,
|
|
# allow minimal control over the requests.
|
|
# For greater control, consider using {request objects}[rdoc-ref:Net::HTTPRequest].
|
|
#
|
|
# == 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.
|
|
#
|
|
# == \HTTP 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 {Strategies}[rdoc-ref:Net::HTTP@Strategies].
|
|
#
|
|
# === 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 returned response is an instance of a subclass of Net::HTTPResponse.
|
|
# See the {response class hierarchy}[rdoc-ref:Net::HTTPResponse@Response+Subclasses].
|
|
#
|
|
# In particular, class Net::HTTPRedirection is the parent
|
|
# of all redirection classes.
|
|
# This allows you to craft a case statement to handle redirections properly:
|
|
#
|
|
# def fetch(uri, limit = 10)
|
|
# # You should choose a better exception.
|
|
# raise ArgumentError, 'Too many HTTP redirects' if limit == 0
|
|
#
|
|
# res = Net::HTTP.get_response(URI(uri))
|
|
# case res
|
|
# when Net::HTTPSuccess # Any success class.
|
|
# res
|
|
# when Net::HTTPRedirection # Any redirection class.
|
|
# location = res['Location']
|
|
# warn "Redirected to #{location}"
|
|
# fetch(location, limit - 1)
|
|
# else # Any other class.
|
|
# res.value
|
|
# end
|
|
# end
|
|
#
|
|
# fetch(uri)
|
|
#
|
|
# == Basic Authentication
|
|
#
|
|
# Basic authentication is performed according to
|
|
# {RFC2617}[http://www.ietf.org/rfc/rfc2617.txt]:
|
|
#
|
|
# req = Net::HTTP::Get.new(uri)
|
|
# req.basic_auth('user', 'pass')
|
|
# res = Net::HTTP.start(hostname) do |http|
|
|
# http.request(req)
|
|
# end
|
|
#
|
|
# == 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.
|
|
#
|
|
# Net::HTTP.start(hostname) do |http|
|
|
# req = Net::HTTP::Get.new(uri)
|
|
# http.request(req) do |res|
|
|
# open('t.tmp', 'w') do |f|
|
|
# res.read_body do |chunk|
|
|
# f.write chunk
|
|
# end
|
|
# end
|
|
# end
|
|
# end
|
|
#
|
|
# == HTTPS
|
|
#
|
|
# HTTPS is enabled for an \HTTP connection by Net::HTTP#use_ssl=:
|
|
#
|
|
# Net::HTTP.start(hostname, :use_ssl => true) do |http|
|
|
# req = Net::HTTP::Get.new(uri)
|
|
# res = http.request(req)
|
|
# end
|
|
#
|
|
# Or if you simply want to make a GET request, you may pass in a 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 https://jsonplaceholder.typicode.com/>
|
|
# Net::HTTP.get(uri)
|
|
#
|
|
# == Proxy Server
|
|
#
|
|
# An \HTTP object can have
|
|
# a {proxy server}[https://en.wikipedia.org/wiki/Proxy_server].
|
|
#
|
|
# You can create an \HTTP object with a proxy server
|
|
# using method Net::HTTP.new or method Net::HTTP.start.
|
|
#
|
|
# The proxy may be defined either by argument +p_addr+
|
|
# or by environment variable <tt>'http_proxy'</tt>.
|
|
#
|
|
# === Proxy Using Argument +p_addr+ as a \String
|
|
#
|
|
# When argument +p_addr+ is a string hostname,
|
|
# the returned +http+ has the given host as its proxy:
|
|
#
|
|
# http = Net::HTTP.new(hostname, nil, 'proxy.example')
|
|
# http.proxy? # => true
|
|
# http.proxy_from_env? # => false
|
|
# http.proxy_address # => "proxy.example"
|
|
# # These use default values.
|
|
# http.proxy_port # => 80
|
|
# http.proxy_user # => nil
|
|
# http.proxy_pass # => nil
|
|
#
|
|
# The port, username, and password for the proxy may also be given:
|
|
#
|
|
# http = Net::HTTP.new(hostname, nil, 'proxy.example', 8000, 'pname', 'ppass')
|
|
# # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
|
|
# http.proxy? # => true
|
|
# http.proxy_from_env? # => false
|
|
# http.proxy_address # => "proxy.example"
|
|
# http.proxy_port # => 8000
|
|
# http.proxy_user # => "pname"
|
|
# http.proxy_pass # => "ppass"
|
|
#
|
|
# === Proxy Using '<tt>ENV['http_proxy']</tt>'
|
|
#
|
|
# When environment variable <tt>'http_proxy'</tt>
|
|
# is set to a \URI string,
|
|
# the returned +http+ will have the server at that URI as its proxy;
|
|
# note that the \URI string must have a protocol
|
|
# such as <tt>'http'</tt> or <tt>'https'</tt>:
|
|
#
|
|
# ENV['http_proxy'] = 'http://example.com'
|
|
# http = Net::HTTP.new(hostname)
|
|
# http.proxy? # => true
|
|
# http.proxy_from_env? # => true
|
|
# http.proxy_address # => "example.com"
|
|
# # These use default values.
|
|
# http.proxy_port # => 80
|
|
# http.proxy_user # => nil
|
|
# http.proxy_pass # => nil
|
|
#
|
|
# The \URI string may include proxy username, password, and port number:
|
|
#
|
|
# ENV['http_proxy'] = 'http://pname:ppass@example.com:8000'
|
|
# http = Net::HTTP.new(hostname)
|
|
# http.proxy? # => true
|
|
# http.proxy_from_env? # => true
|
|
# http.proxy_address # => "example.com"
|
|
# http.proxy_port # => 8000
|
|
# http.proxy_user # => "pname"
|
|
# http.proxy_pass # => "ppass"
|
|
#
|
|
# === Filtering Proxies
|
|
#
|
|
# With method Net::HTTP.new (but not Net::HTTP.start),
|
|
# you can use argument +p_no_proxy+ to filter proxies:
|
|
#
|
|
# - Reject a certain address:
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example')
|
|
# http.proxy_address # => nil
|
|
#
|
|
# - Reject certain domains or subdomains:
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'my.proxy.example', 8000, 'pname', 'ppass', 'proxy.example')
|
|
# http.proxy_address # => nil
|
|
#
|
|
# - Reject certain addresses and port combinations:
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example:1234')
|
|
# http.proxy_address # => "proxy.example"
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example:8000')
|
|
# http.proxy_address # => nil
|
|
#
|
|
# - Reject a list of the types above delimited using a comma:
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000')
|
|
# http.proxy_address # => nil
|
|
#
|
|
# http = Net::HTTP.new('example.com', nil, 'my.proxy', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000')
|
|
# http.proxy_address # => nil
|
|
#
|
|
# == Compression and Decompression
|
|
#
|
|
# \Net::HTTP does not compress the body of a request before sending.
|
|
#
|
|
# By default, \Net::HTTP adds header <tt>'Accept-Encoding'</tt>
|
|
# to a new {request object}[rdoc-ref:Net::HTTPRequest]:
|
|
#
|
|
# Net::HTTP::Get.new(uri)['Accept-Encoding']
|
|
# # => "gzip;q=1.0,deflate;q=0.6,identity;q=0.3"
|
|
#
|
|
# This requests the server to zip-encode the response body if there is one;
|
|
# the server is not required to do so.
|
|
#
|
|
# \Net::HTTP does not automatically decompress a response body
|
|
# if the response has header <tt>'Content-Range'</tt>.
|
|
#
|
|
# Otherwise decompression (or not) depends on the value of header
|
|
# {Content-Encoding}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#content-encoding-response-header]:
|
|
#
|
|
# - <tt>'deflate'</tt>, <tt>'gzip'</tt>, or <tt>'x-gzip'</tt>:
|
|
# decompresses the body and deletes the header.
|
|
# - <tt>'none'</tt> or <tt>'identity'</tt>:
|
|
# does not decompress the body, but deletes the header.
|
|
# - Any other value:
|
|
# leaves the body and header unchanged.
|
|
#
|
|
# == What's Here
