Overview
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 HTTP.
Class Attribute Summary
-
.body_permitted? ⇒ Boolean
readonly
true if the response has a body.
Class Method Summary

readonly
The HTTP result code string.
-
#http_version
readonly
The HTTP version supported by the server.
-

Instance Attribute Details
#body (rw) Also known as: #entity
Returns the full entity body.
Calling this method a second or subsequent time will return the string already read.

#body=(value) (rw)
Because it may be necessary to modify the body, Eg, decompression this method facilitates that.
#code (readonly)
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.

#http_version (readonly)
The HTTP version supported by the server.

#read_body(dest = nil, &block)
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.
