HTTP response class. This class wraps response header and entity. Mixes in the HTTPHeader module, which provides access to response header values both via hash-like methods and 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.

  xxx        HTTPUnknownResponse



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


The HTTP version supported by the server.


HTTP result message. For example, 'Not Found'.


HTTP result message. For example, 'Not Found'.

Public Class Methods

body_permitted?() click to toggle source

true if the response has body.

               # File net/http.rb, line 1900
def HTTPResponse.body_permitted?

Public Instance Methods

body() click to toggle source

Returns the entity body.

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

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.rb, line 2320
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.rb, line 2326
def body=(value)
  @body = value
entity() click to toggle source
Alias for: body
inspect() click to toggle source
               # File net/http.rb, line 2193
def inspect
  "#<#{self.class} #{@code} #{@message} readbody=#{@read}>"
read_body(dest = nil, &block) click to toggle source

Gets entity body. If the block given, yields it to block. The body is provided in fragments, as it is read in from the socket.

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

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.rb, line 2288
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

to_ary() click to toggle source

For backward compatibility. To allow Net::HTTP 1.1 style assignment e.g.

response, body = Net::HTTP.get(....)
               # File net/http.rb, line 2202
def to_ary
  warn "net/http.rb: warning: Net::HTTP v1.1 style assignment found at #{caller(1)[0]}; use `response = http.get(...)' instead." if $VERBOSE
  res = self.dup
  class << res
    undef to_ary
  [res, res.body]
value() click to toggle source

Raises HTTP error if the response is not 2xx.

               # File net/http.rb, line 2228
def value
  error! unless self.kind_of?(HTTPSuccess)
