Class/Module Index [+]



HTTP response class.

This class wraps together the response header and the response body (the entity requested).

It mixes in the HTTPHeader module, which provides access to response header values both via hash-like methods and via individual readers.

Note that each possible HTTP response code defines its own HTTPResponse subclass. These are listed below.

All classes are defined under the Net module. Indentation indicates inheritance. For a list of the classes see Net::HTTP.



The HTTP result code string. For example, ‘302’. You can also determine the response type by examining which response subclass the response object is an instance of.


Set to true automatically when the request did not contain an Accept-Encoding header from the user.


The HTTP version supported by the server.


The HTTP result message sent by the server. For example, ‘Not Found’.


The HTTP result message sent by the server. For example, ‘Not Found’.


The URI used to fetch this response. The response URI is only available if a URI was used to create the request.

Public Class Methods

body_permitted?() click to toggle source

true if the response has a body.

               # File net/http/response.rb, line 19
def body_permitted?

Public Instance Methods

body() click to toggle source

Returns the full entity body.

Calling this method a second or subsequent time will return the string already read.

http.request_get('/index.html') {|res|
  puts res.body

http.request_get('/index.html') {|res|
  p res.body.object_id   # 538149362
  p res.body.object_id   # 538149362
               # File net/http/response.rb, line 225
def body
Also aliased as: entity
body=(value) click to toggle source

Because it may be necessary to modify the body, Eg, decompression this method facilitates that.

               # File net/http/response.rb, line 231
def body=(value)
  @body = value
entity() click to toggle source
Alias for: body
inspect() click to toggle source
               # File net/http/response.rb, line 106
def inspect
  "#<#{self.class} #{@code} #{@message} readbody=#{@read}>"
read_body(dest = nil, &block) click to toggle source

Gets the entity body returned by the remote HTTP server.

If a block is given, the body is passed to the block, and the body is provided in fragments, as it is read in from the socket.

Calling this method a second or subsequent time for the same HTTPResponse object will return the value already read.

http.request_get('/index.html') {|res|
  puts res.read_body

http.request_get('/index.html') {|res|
  p res.read_body.object_id   # 538149362
  p res.read_body.object_id   # 538149362

# using iterator
http.request_get('/index.html') {|res|
  res.read_body do |segment|
    print segment
               # File net/http/response.rb, line 193
def read_body(dest = nil, &block)
  if @read
    raise IOError, "#{self.class}\#read_body called twice" if dest or block
    return @body
  to = procdest(dest, block)
  if @body_exist
    read_body_0 to
    @body = to
    @body = nil
  @read = true

value() click to toggle source

Raises an HTTP error if the response is not 2xx (success).

               # File net/http/response.rb, line 127
def value
  error! unless self.kind_of?(Net::HTTPSuccess)
