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.
Example
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 }
