Reading data from a socket in ruby in a multithreaded environment

I am trying to read an HTTP packet via a socket in ruby, and for some reason my code keeps on blocking whilst calling recv

开发者_JS百科socket = TCPSocket.new("localhost",80)
socket.send r.join("\r\n"), 0
socket.flush
#We're only interested in the string "HTTP/1.1 XXX"
if http_status = get_http_status(socket.recv_nonblock(12))
    if http_status == 200
        $logger.info "Wrote #{message_packet}"
    else
        $logger.warn "Resubmitting message because #{line} is not 200"
        @queue.publish(message) 
    end
end

#Get rid of the rest of the content
the_rest = socket.recv(1000)
while(the_rest != "") do
    the_rest = socket.recv(1000)    
end

From what I understand of recv it should return nothing if there's no data waiting on the socket?

The connection could be a keep-alive connection. So, your recv() call wont end by itself. You will need to read the Content-Lenght header, then do a read of that many bytes from the content. After that you can get out of the RECV loop.

Or alternately, issue the request by setting "Connection: close" header so that the server closes the connection after sending the response.
