Protocol
Net::HTTP provides a rich library which can be used to build HTTP user-agents. For more details about HTTP see [RFC2616](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.
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.
Net::HTTP.get('example.com', '/index.html') # => String
uri = URI('http://example.com/index.html?count=10') Net::HTTP.get(uri) # => String
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)
uri = URI('http://www.example.com/search.cgi') res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50') puts res.body
uri = URI('http://www.example.com/search.cgi') res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50') puts res.body
The following example code can be used as the basis of a 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
::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.
The request types Net::HTTP supports are listed below in the section “HTTP Request Classes”.
If you wish to re-use a connection across multiple HTTP requests without automatically closing it you can use ::new instead of ::start. request will automatically open a connection to the server if one is not currently open. You can manually close the connection with finish.
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.
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?
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')
A POST can be made using the Net::HTTP::Post request class. This example creates a urlencoded 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
At this time Net::HTTP does not support multipart/form-data. To send multipart/form-data use Net::HTTPGenericRequest#body= and Net::HTTPHeader#content_type=:
req = Net::HTTP::Post.new(uri) req.body = multipart_data req.content_type = '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).
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 is performed according to [RFC2617](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
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 is enabled for an HTTP connection by #use_ssl=.
uri = URI('https://secure.example.com/some_path?query=string') Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http| request = Net::HTTP::Get.new uri response = http.request request # Net::HTTPResponse object end
In previous versions of ruby you would need to require 'net/https' to use HTTPS. This is no longer true.
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 ::new for further details and examples such as proxies that require a username and password.
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.

There is also the Net::HTTPBadResponse exception which is raised when there is a protocol error.
Sets path of a CA certification file in PEM format.
The file can contain several CA certificates.
Sets an OpenSSL::X509::Certificate object as client certificate. (This method is appeared in Michal Rokos's OpenSSL extension).
Seconds to wait for 100 Continue response. If the HTTP object does not receive a response in this many
seconds it sends the request body. The default value is nil
.
Seconds to reuse the connection of the previous request. If the idle time is less than this Keep-Alive Timeout, Net::HTTP reuses the TCP/IP socket used by the previous communication. The default value is 2 seconds.
Sets an OpenSSL::PKey::RSA or OpenSSL::PKey::DSA object. (This method is appeared in Michal Rokos's OpenSSL extension.)
Number of seconds to wait for the connection to open. Any number may be
used, including Floats for fractional seconds. If the HTTP object cannot open a connection in this many
seconds, it raises a Net::OpenTimeout exception. The default value is
nil
.
Number of seconds to wait for one block to be read (via one read(2) call). Any number may be used, including Floats for fractional seconds. If the HTTP object cannot read data in this many seconds, it raises a Net::ReadTimeout exception. The default value is 60 seconds.
Creates an HTTP proxy class which behaves like Net::HTTP, but performs all access via the specified proxy.
This class is obsolete. You may pass these same parameters directly to ::new. See ::new for details of the arguments.
# File net/http.rb, line 973 def HTTP.Proxy(p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil) return self unless p_addr Class.new(self) { @is_proxy_class = true if p_addr == :ENV then @proxy_from_env = true @proxy_address = nil @proxy_port = nil else @proxy_from_env = false @proxy_address = p_addr @proxy_port = p_port || default_port end @proxy_user = p_user @proxy_pass = p_pass } end
The default port to use for HTTP requests; defaults to 80.
# File net/http.rb, line 517 def HTTP.default_port http_default_port() end
Sends a GET request to the target and returns the HTTP response as a string. The target can either be
specified as (uri
), or as (host
,
path
, port
= 80); so:
print Net::HTTP.get(URI('http://www.example.com/index.html'))
or:
print Net::HTTP.get('www.example.com', '/index.html')
# File net/http.rb, line 453 def HTTP.get(uri_or_host, path = nil, port = nil) get_response(uri_or_host, path, port).body end
Gets the body text from the target and outputs it to $stdout. The target
can either be specified as (uri
), or as (host
,
path
, port
= 80); so:
Net::HTTP.get_print URI('http://www.example.com/index.html')
or:
Net::HTTP.get_print 'www.example.com', '/index.html'
# File net/http.rb, line 434 def HTTP.get_print(uri_or_host, path = nil, port = nil) get_response(uri_or_host, path, port) {|res| res.read_body do |chunk| $stdout.print chunk end } nil end
Sends a GET request to the target and returns the HTTP response as a Net::HTTPResponse object. The target can
either be specified as (uri
), or as (host
,
path
, port
= 80); so:
res = Net::HTTP.get_response(URI('http://www.example.com/index.html')) print res.body
or:
res = Net::HTTP.get_response('www.example.com', '/index.html') print res.body
# File net/http.rb, line 469 def HTTP.get_response(uri_or_host, path = nil, port = nil, &block) if path host = uri_or_host new(host, port || HTTP.default_port).start {|http| return http.request_get(path, &block) } else uri = uri_or_host start(uri.hostname, uri.port, :use_ssl => uri.scheme == 'https') {|http| return http.request_get(uri, &block) } end end
The default port to use for HTTP requests; defaults to 80.
# File net/http.rb, line 522 def HTTP.http_default_port 80 end
The default port to use for HTTPS requests; defaults to 443.
# File net/http.rb, line 527 def HTTP.https_default_port 443 end
Creates a new Net::HTTP object without opening a TCP connection or HTTP session.
The address
should be a DNS hostname or IP address, the
port
is the port the server operates on. If no
port
is given the default port for HTTP or HTTPS is used.
If none of the p_
arguments are given, the proxy host and port
are taken from the http_proxy
environment variable (or its
uppercase equivalent) if present. If the proxy requires authentication you
must supply it by hand. See URI::Generic#find_proxy for details of proxy
detection from the environment. To disable proxy detection set
p_addr
to nil.
If you are connecting to a custom proxy, p_addr
the DNS name
or IP address of the proxy host, p_port
the port to use to
access the proxy, and p_user
and p_pass
the
username and password if authorization is required to use the proxy.
# File net/http.rb, line 608 def HTTP.new(address, port = nil, p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil) http = super address, port if proxy_class? then # from Net::HTTP::Proxy() http.proxy_from_env = @proxy_from_env http.proxy_address = @proxy_address http.proxy_port = @proxy_port http.proxy_user = @proxy_user http.proxy_pass = @proxy_pass elsif p_addr == :ENV then http.proxy_from_env = true else http.proxy_address = p_addr http.proxy_port = p_port || default_port http.proxy_user = p_user http.proxy_pass = p_pass end http end
Creates a new Net::HTTP object for the specified
server address, without opening the TCP connection or initializing the HTTP session. The address
should be a DNS
hostname or IP address.
# File net/http.rb, line 632 def initialize(address, port = nil) @address = address @port = (port || HTTP.default_port) @local_host = nil @local_port = nil @curr_http_version = HTTPVersion @keep_alive_timeout = 2 @last_communicated = nil @close_on_empty_response = false @socket = nil @started = false @open_timeout = nil @read_timeout = 60 @continue_timeout = nil @debug_output = nil @proxy_from_env = false @proxy_uri = nil @proxy_address = nil @proxy_port = nil @proxy_user = nil @proxy_pass = nil @use_ssl = false @ssl_context = nil @ssl_session = nil @enable_post_connection_check = true @sspi_enabled = false SSL_IVNAMES.each do |ivname| instance_variable_set ivname, nil end end
Posts HTML form data to the specified URI object. The form data must be provided as a Hash mapping from String to String. Example:
{ "cmd" => "search", "q" => "ruby", "max" => "50" }
This method also does Basic Authentication iff url
.user
exists. But userinfo for authentication is deprecated (RFC3986). So this
feature will be removed.
Example:
require 'net/http' require 'uri' Net::HTTP.post_form URI('http://www.example.com/search.cgi'), { "q" => "ruby", "max" => "50" }
# File net/http.rb, line 502 def HTTP.post_form(url, params) req = Post.new(url) req.form_data = params req.basic_auth url.user, url.password if url.user start(url.hostname, url.port, :use_ssl => url.scheme == 'https' ) {|http| http.request(req) } end
returns true if self is a class which was created by HTTP::Proxy.
# File net/http.rb, line 996 def proxy_class? defined?(@is_proxy_class) ? @is_proxy_class : false end
Creates a new Net::HTTP object, then additionally opens the TCP connection and HTTP session.
Arguments are the following:
hostname or IP address of the server
port of the server
address of proxy
port of proxy
user of proxy
pass of proxy
optional hash
opt sets following values by its accessor. The keys are #ca_file, #ca_path, cert, #cert_store, ciphers, #close_on_empty_response, key, #open_timeout, #read_timeout, #ssl_timeout, #ssl_version, use_ssl, #verify_callback, #verify_depth and verify_mode. If you set :use_ssl as true, you can use https and default value of #verify_mode is set as OpenSSL::SSL::VERIFY_PEER.
If the optional block is given, the newly created Net::HTTP object is passed to it and closed when the block finishes. In this case, the return value of this method is the return value of the block. If no block is given, the return value of this method is the newly created Net::HTTP object itself, and the caller is responsible for closing it upon completion using the finish() method.
# File net/http.rb, line 565 def HTTP.start(address, *arg, &block) # :yield: +http+ arg.pop if opt = Hash.try_convert(arg[-1]) port, p_addr, p_port, p_user, p_pass = *arg port = https_default_port if !port && opt && opt[:use_ssl] http = new(address, port, p_addr, p_port, p_user, p_pass) if opt if opt[:use_ssl] opt = {verify_mode: OpenSSL::SSL::VERIFY_PEER}.update(opt) end http.methods.grep(/\A(\w+)=\z/) do |meth| key = $1.to_sym opt.key?(key) or next http.__send__(meth, opt[key]) end end http.start(&block) end
Turns on net/http 1.2 (ruby 1.8) features. Defaults to ON in ruby 1.8 or later.
# File net/http.rb, line 400 def HTTP.version_1_2 true end
Returns true if net/http is in version 1.2 mode. Defaults to true.
# File net/http.rb, line 406 def HTTP.version_1_2? true end
Setter for the #continue_timeout attribute.
# File net/http.rb, line 725 def continue_timeout=(sec) @socket.continue_timeout = sec if @socket @continue_timeout = sec end
Sends a COPY request to the path
and gets a response, as an HTTPResponse object.
# File net/http.rb, line 1241 def copy(path, initheader = nil) request(Copy.new(path, initheader)) end
Sends a DELETE request to the path
and gets a response, as an
HTTPResponse object.
# File net/http.rb, line 1229 def delete(path, initheader = {'Depth' => 'Infinity'}) request(Delete.new(path, initheader)) end
Finishes the HTTP session and closes the TCP connection. Raises IOError if the session has not been started.
# File net/http.rb, line 942 def finish raise IOError, 'HTTP session not yet started' unless started? do_finish end
Retrieves data from path
on the connected-to host which may be
an absolute path String or a URI to extract the path from.
initheader
must be a Hash like { 'Accept' =>
'/', … }, and it defaults to an empty hash. If
initheader
doesn't have the key 'accept-encoding',
then a value of “gzip;q=1.0,deflate;q=0.6,identity;q=0.3” is used, so that
gzip compression is used in preference to deflate compression, which is
used in preference to no compression. Ruby doesn't have libraries to
support the compress (Lempel-Ziv) compression, so that is not supported.
The intent of this is to reduce bandwidth by default. If this routine
sets up compression, then it does the decompression also, removing the
header as well to prevent confusion. Otherwise it leaves the body as it
found it.
This method returns a Net::HTTPResponse object.
If called with a block, yields each fragment of the entity body in turn as a string as it is read from the socket. Note that in this case, the returned response object will not contain a (meaningful) body.
dest
argument is obsolete. It still works but you must not use
it.
This method never raises an exception.
response = http.get('/index.html') # using block File.open('result.txt', 'w') {|f| http.get('/~foo/') do |str| f.write str end }
# File net/http.rb, line 1129 def get(path, initheader = {}, dest = nil, &block) # :yield: +body_segment+ res = nil request(Get.new(path, initheader)) {|r| r.read_body dest, &block res = r } res end
Gets only the header from path
on the connected-to host.

Sends a OPTIONS request to the path
and gets a response, as an
HTTPResponse object.

When this method is called with a block, it passes the Net::HTTP object to the block, and closes the TCP connection and HTTP session after the block has been executed.
When called with a block, it returns the return value of the block; otherwise, it returns self.
# File net/http.rb, line 847 def start # :yield: http raise IOError, 'HTTP session already opened' if @started if block_given? begin do_start return yield(self) ensure do_finish end end do_start self end
Returns true if the HTTP session has been started.
# File net/http.rb, line 737 def started? @started end
Sends a TRACE request to the path
and gets a response, as an
HTTPResponse object.
# File net/http.rb, line 1253 def trace(path, initheader = nil) request(Trace.new(path, initheader)) end
Sends a UNLOCK request to the path
and gets a response, as an
HTTPResponse object.
# File net/http.rb, line 1211 def unlock(path, body, initheader = nil) request(Unlock.new(path, initheader), body) end
Turn on/off SSL. This flag must be set before starting session. If you change use_ssl value after session started, a Net::HTTP object raises IOError.
# File net/http.rb, line 754 def use_ssl=(flag) flag = flag ? true : false if started? and @use_ssl != flag raise IOError, "use_ssl value changed, but session already started" end @use_ssl = flag end
Returns true if SSL/TLS is being used with HTTP.
