# class Net::HTTP

## 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](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

### 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](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.

## `HTTP` Request Classes¶ ↑

Here is the `HTTP` request class hierarchy.

### Public Class Methods

Proxy(p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil) click to toggle source

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 `Net::HTTP.new`. See `Net::HTTP.new` for details of the arguments.

    # File lib/net/http.rb, line 1147
    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

default_port() click to toggle source

The default port to use for `HTTP` requests; defaults to 80.

    # File lib/net/http.rb, line 561
    def HTTP.default_port
      http_default_port()
    end

get(uri_or_host, path_or_headers = nil, port = nil) click to toggle source

Sends a GET request to the target and returns the `HTTP` response as a string. The target can either be specified as (`uri`, `headers`), 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')

you can also specify request headers:

    Net::HTTP.get(URI('http://www.example.com/index.html'), { 'Accept' => 'text/html' })

    # File lib/net/http.rb, line 474
    def HTTP.get(uri_or_host, path_or_headers = nil, port = nil)
      get_response(uri_or_host, path_or_headers, port).body
    end

get_print(uri_or_host, path_or_headers = nil, port = nil) click to toggle source

Gets the body text from the target and outputs it to $stdout. The target can either be specified as (`uri`, `headers`), 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'

you can also specify request headers:

    Net::HTTP.get_print URI('http://www.example.com/index.html'), { 'Accept' => 'text/html' }

    # File lib/net/http.rb, line 451
    def HTTP.get_print(uri_or_host, path_or_headers = nil, port = nil)
      get_response(uri_or_host, path_or_headers, port) {|res|
        res.read_body do |chunk|
          $stdout.print chunk
        end
      }
      nil
    end

get_response(uri_or_host, path_or_headers = nil, port = nil, &block) click to toggle source

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`, `headers`), 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

you can also specify request headers:

    Net::HTTP.get_response(URI('http://www.example.com/index.html'), { 'Accept' => 'text/html' })

    # File lib/net/http.rb, line 494
    def HTTP.get_response(uri_or_host, path_or_headers = nil, port = nil, &block)
      if path_or_headers && !path_or_headers.is_a?(Hash)
        host = uri_or_host
        path = path_or_headers
        new(host, port || HTTP.default_port).start {|http|
          return http.request_get(path, &block)
        }
      else
        uri = uri_or_host
        headers = path_or_headers
        start(uri.hostname, uri.port,
              :use_ssl => uri.scheme == 'https') {|http|
          return http.request_get(uri, headers, &block)
        }
      end
    end

http_default_port() click to toggle source

The default port to use for `HTTP` requests; defaults to 80.

    # File lib/net/http.rb, line 566
    def HTTP.http_default_port
      80
    end

https_default_port() click to toggle source

The default port to use for HTTPS requests; defaults to 443.

    # File lib/net/http.rb, line 571
    def HTTP.https_default_port
      443
    end

Alias for: version_1_2?
new(address, port = nil, p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil, p_no_proxy = nil) click to toggle source

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` specifies the DNS name or IP address of the proxy host, `p_port` the port to use to access the proxy, `p_user` and `p_pass` the username and password if authorization is required to use the proxy, and p_no_proxy hosts which do not use the proxy.

Calls superclass method

    # File lib/net/http.rb, line 655

    Net::HTTP.post URI('http://www.example.com/api/search'),
                   { "q" => "ruby", "max" => "50" }.to_json,
                   "Content-Type" => "application/json"

    # File lib/net/http.rb, line 522
    def HTTP.post(url, data, header = nil)
      start(url.hostname, url.port,
            :use_ssl => url.scheme == 'https' ) {|http|
        http.post(url, data, header)
      }
    end

post_form(url, params) click to toggle source

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 if and only if `url`.user exists. But userinfo for authentication is deprecated (RFC3986). So this feature will be removed.

Example:

    require 'net/http'

    Net::HTTP.post_form URI('http://www.example.com/search.cgi'),
                        { "q" => "ruby", "max" => "50" }

    # File lib/net/http.rb, line 546
    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

proxy_class?() click to toggle source

returns true if self is a class which was created by `HTTP::Proxy`.

    # File lib/net/http.rb, line 1170
    def proxy_class?
      defined?(@is_proxy_class) ? @is_proxy_class : false
    end

start(address, port, p_addr, p_port, p_user, p_pass, &block) click to toggle source
start(address, port=nil, p_addr=:ENV, p_port=nil, p_user=nil, p_pass=nil, opt, &block)

Creates a new `Net::HTTP` object, then additionally opens the TCP connection and `HTTP` session.

Arguments are the following:

address

  hostname or IP address of the server

port

  port of the server

p_addr

  address of proxy

p_port

  port of proxy

p_user

  user of proxy

p_pass

  pass of proxy

opt

  optional hash

opt sets following values by its accessor. The keys are ipaddr, `ca_file`, `ca_path`, cert, `cert_store`, ciphers, `keep_alive_timeout`, `close_on_empty_response`, key, `open_timeout`, `read_timeout`, `write_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 lib/net/http.rb, line 609
    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
      p_addr = :ENV if arg.size < 2
      port = https_default_port if !port && opt && opt[:use_ssl]
      http = new(address, port, p_addr, p_port, p_user, p_pass)
      http.ipaddr = opt[:ipaddr] if opt && opt[:ipaddr]

      if opt
        if opt[:use_ssl]
          opt = {verify_mode: OpenSSL::SSL::VERIFY_PEER}.update(opt)
        end

finish() click to toggle source

Finishes the `HTTP` session and closes the TCP connection. Raises `IOError` if the session has not been started.

    # File lib/net/http.rb, line 1116
    def finish
      raise IOError, 'HTTP session not yet started' unless started?
      do_finish
    end

get(path, initheader = nil, dest = nil) { |body_segment| ... } click to toggle source

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|
