Net::HTTPResponse

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

Correspondence HTTP code => class is stored in CODE_TO_OBJ constant:

Net::HTTPResponse::CODE_TO_OBJ['404'] #=> Net::HTTPNotFound

Attributes

code[R]

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.

decode_content[RW]

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

http_version[R]

The HTTP version supported by the server.

message[R]

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

msg[R]

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

uri[R]

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 22
def body_permitted?
  self::HAS_BODY
end

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 234
def body
  read_body()
end
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 240
def body=(value)
  @body = value
end
entity() click to toggle source
Alias for: body
inspect() click to toggle source 
 
               # File net/http/response.rb, line 109
def inspect
  "#<#{self.class} #{@code} #{@message} readbody=#{@read}>"
end
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.

If dest argument is given, response is read into that variable, with dest#<< method (it could be String or IO, or any other object responding to <<).

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
  end
}

 
               # File net/http/response.rb, line 202
def read_body(dest = nil, &block)
  if @read
    raise IOError, "#{self.class}\#read_body called twice" if dest or block
    return @body
  end
  to = procdest(dest, block)
  stream_check
  if @body_exist
    read_body_0 to
    @body = to
  else
    @body = nil
  end
  @read = true

  @body
end
value() click to toggle source

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

 
               # File net/http/response.rb, line 132
def value
  error! unless self.kind_of?(Net::HTTPSuccess)
end
