Net::HTTPSession

What Is This Library?

This library provides your program functions to access WWW documents via HTTP, Hyper Text Transfer Protocol version 1.1. For details of HTTP, refer [RFC2616] (www.ietf.org/rfc/rfc2616.txt).

Examples

Getting Document From WWW Server

Example #1: Simple GET+print

require 'net/http'
Net::HTTP.get_print 'www.example.com', '/index.html'

Example #2: Simple GET+print by URL

require 'net/http'
require 'uri'
Net::HTTP.get_print URI.parse('http://www.example.com/index.html')

Example #3: More generic GET+print

require 'net/http'
require 'uri'

url = URI.parse('http://www.example.com/index.html')
res = Net::HTTP.start(url.host, url.port) {|http|
  http.get('/index.html')
}
puts res.body

Example #4: More generic GET+print

require 'net/http'

url = URI.parse('http://www.example.com/index.html')
req = Net::HTTP::Get.new(url.path)
res = Net::HTTP.start(url.host, url.port) {|http|
  http.request(req)
}
puts res.body

Posting Form Data

require 'net/http'
require 'uri'

#1: Simple POST
res = Net::HTTP.post_form(URI.parse('http://www.example.com/search.cgi'),
                          {'q'=>'ruby', 'max'=>'50'})
puts res.body

#2: POST with basic authentication
res = Net::HTTP.post_form(URI.parse('http://jack:pass@www.example.com/todo.cgi'),
                                    {'from'=>'2005-01-01', 'to'=>'2005-03-31'})
puts res.body

#3: Detailed control
url = URI.parse('http://www.example.com/todo.cgi')
req = Net::HTTP::Post.new(url.path)
req.basic_auth 'jack', 'pass'
req.set_form_data({'from'=>'2005-01-01', 'to'=>'2005-03-31'}, ';')
res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
case res
when Net::HTTPSuccess, Net::HTTPRedirection
  # OK
else
  res.error!
end

Accessing via Net::HTTP.Proxy

Net::HTTP.Proxy creates http proxy class. It has same methods of Net::HTTP but its instances always connect to proxy, instead of given host.

require 'net/http'

proxy_addr = 'your.proxy.host'
proxy_port = 8080
        :
Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com') {|http|
  # always connect to your.proxy.addr:8080
        :
}

Since Net::HTTP.Proxy returns Net::HTTP itself when proxy_addr is nil, there's no need to change code if there's proxy or not.

There are two additional parameters in Net::HTTP.Proxy which allow to specify proxy user name and password:

Net::HTTP::Proxy(proxy_addr, proxy_port, proxy_user = nil, proxy_pass = nil)

You may use them to work with authorization-enabled proxies:

require 'net/http'
require 'uri'

proxy_host = 'your.proxy.host'
proxy_port = 8080
uri = URI.parse(ENV['http_proxy'])
proxy_user, proxy_pass = uri.userinfo.split(/:/) if uri.userinfo
Net::HTTP::Proxy(proxy_host, proxy_port,
                 proxy_user, proxy_pass).start('www.example.com') {|http|
  # always connect to your.proxy.addr:8080 using specified username and password
        :
}

Note that net/http never rely on HTTP_PROXY environment variable. If you want to use proxy, set it explicitly.

Following Redirection

require 'net/http'
require 'uri'

def fetch(uri_str, limit = 10)
  # You should choose better exception.
  raise ArgumentError, 'HTTP redirect too deep' if limit == 0

  response = Net::HTTP.get_response(URI.parse(uri_str))
  case response
  when Net::HTTPSuccess     then response
  when Net::HTTPRedirection then fetch(response['location'], limit - 1)
  else
    response.error!
  end
end

print fetch('http://www.ruby-lang.org')

Net::HTTPSuccess and Net::HTTPRedirection is a HTTPResponse class. All HTTPResponse objects belong to its own response class which indicate HTTP result status. For details of response classes, see section “HTTP Response Classes”.

Basic Authentication

require 'net/http'

Net::HTTP.start('www.example.com') {|http|
  req = Net::HTTP::Get.new('/secret-page.html')
  req.basic_auth 'account', 'password'
  response = http.request(req)
  print response.body
}

Switching Net::HTTP versions

You can use net/http.rb 1.1 features (bundled with Ruby 1.6) by calling Net::HTTP.version_1_1. Calling Net::HTTP.version_1_2 allows you to use 1.2 features again.

# example
Net::HTTP.start {|http1| ...(http1 has 1.2 features)... }

Net::HTTP.version_1_1
Net::HTTP.start {|http2| ...(http2 has 1.1 features)... }

Net::HTTP.version_1_2
Net::HTTP.start {|http3| ...(http3 has 1.2 features)... }

This function is NOT thread-safe.

Attributes

proxy_address[R]
proxy_pass[R]
proxy_port[R]
proxy_user[R]
address[R]

The host name to connect to.

close_on_empty_response[RW]
open_timeout[RW]

Seconds to wait until reading one block (by one read(2) call). If the HTTP object cannot open a connection in this many seconds, it raises a TimeoutError exception.

Public Class Methods

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

Creates an HTTP proxy class. Arguments are address/port of proxy host and username/password if authorization on proxy server is required. You can replace the HTTP class with created proxy class.

If ADDRESS is nil, this method returns self (Net::HTTP).

# Example
proxy_class = Net::HTTP::Proxy('proxy.example.com', 8080)
                :
proxy_class.start('www.ruby-lang.org') {|http|
  # connecting proxy.foo.org:8080

Alias for: new
post_form(url, params) click to toggle source

Posts HTML form data to the URL. Form data must be represented as a Hash of String to String, e.g:

{ "cmd" => "search", "q" => "ruby", "max" => "50" }

This method also does Basic Authentication iff URL.user exists.

Example:

require 'net/http'
require 'uri'

HTTP.post_form URI.parse('http://www.example.com/search.cgi'),
               { "q" => "ruby", "max" => "50" }
 
               # File net/http.rb, line 400
def HTTP.post_form(url, params)
  req = Post.new(url.path)
  req.form_data = params
  req.basic_auth url.user, url.password if url.user
  new(url.host, url.port).start {|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 net/http.rb, line 659
def proxy_class?
  @is_proxy_class
end
            
start(address, port = nil, p_addr = nil, p_port = nil, p_user = nil, p_pass = nil) click to toggle source

creates a new Net::HTTP object and opens its TCP connection and HTTP session. 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.

 
               # File net/http.rb, line 439
def HTTP.start(address, port = nil, p_addr = nil, p_port = nil, p_user = nil, p_pass = nil, &block) # :yield: +http+
  new(address, port, p_addr, p_port, p_user, p_pass).start(&block)
end
            
version_1_1() click to toggle source

Turns on net/http 1.1 (ruby 1.6) features. Defaults to OFF in ruby 1.8.

def HTTP.version_1_1
  @newimpl = false
end
            
version_1_1?() click to toggle source

               # File net/http.rb, line 294
def HTTP.version_1_2
  @newimpl = true
end
            
version_1_2?() click to toggle source

Public Instance Methods

active?() click to toggle source
Alias for: started?
copy(path, initheader = nil) click to toggle source

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

 
               # File net/http.rb, line 906
def copy(path, initheader = nil)
  request(Copy.new(path, initheader))
end
            
delete(path, initheader = {'Depth' => 'Infinity'}) click to toggle source

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

def delete(path, initheader = {'Depth' => 'Infinity'})
  request(Delete.new(path, initheader))
end
            
finish() click to toggle source

Finishes HTTP session and closes TCP connection. Raises IOError if not started.

 
               # File net/http.rb, line 601
def finish
  raise IOError, 'HTTP session not yet started' unless started?
  do_finish
end
            
get(path, initheader = nil, dest = nil) click to toggle source

Gets data from path on the connected-to host. header must be a Hash like { 'Accept' => '/', … }.

In version 1.1 (ruby 1.6), this method returns a pair of objects, a Net::HTTPResponse object and the entity body string. In version 1.2 (ruby 1.8), 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.

In version 1.1, this method might raise an exception for 3xx (redirect). In this case you can get a HTTPResponse object by “anException.response”.

In version 1.2, this method never raises exception.

# version 1.1 (bundled with Ruby 1.6)
response, body = http.get('/index.html')

# version 1.2 (bundled with Ruby 1.8 or later)
response = http.get('/index.html')

Alias for: request_get
head(path, initheader = nil) click to toggle source

Gets only the header from path on the connected-to host. header is a Hash like { 'Accept' => '/', … }.

This method returns a Net::HTTPResponse object.

In version 1.1, this method might raise an exception for 3xx (redirect). On the case you can get a HTTPResponse object by “anException.response”. In version 1.2, this method never raises an exception.

post(path, data, initheader = nil, dest = nil) click to toggle source

Posts data (must be a String) to path. header must be a Hash like { 'Accept' => '/', … }.

In version 1.1 (ruby 1.6), this method returns a pair of objects, a Net::HTTPResponse object and an entity body string. In version 1.2 (ruby 1.8), 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 are 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.

In version 1.1, this method might raise an exception for 3xx (redirect). In this case you can get an HTTPResponse object by “anException.response”. In version 1.2, this method never raises exception.

# version 1.1
response, body = http.post('/cgi-bin/search.rb', 'query=foo')

# version 1.2
response = http.post('/cgi-bin/search.rb', 'query=foo')

# using block
File.open('result.txt', 'w') {|f|
  http.post('/cgi-bin/search.rb', 'query=foo') do |str|
    f.write str
  end
}

You should set Content-Type: header field for POST. If no Content-Type: field given, this method uses “application/x-www-form-urlencoded” by default.
