Socket.recv works but not gets or read?
- by Earlz
Hello I've been messing around with Sockets in Ruby some and came across some example code that I tried modifying and broke. I want to know why it's broken.
Server:
require "socket"
dts = TCPServer.new('127.0.0.1', 20000)
loop do
Thread.start(dts.accept) do |s|
print(s, " is accepted\n")
s.write(Time.now)
print(s, " is gone\n")
s.close
end
end
Client that works:
require 'socket'
streamSock = TCPSocket.new( "127.0.0.1", 20000 )
streamSock.print( "Hello\n" )
str = streamSock.recv( 100 )
print str
streamSock.close
Client that is broken
require 'socket'
streamSock = TCPSocket.new( "127.0.0.1", 20000 )
streamSock.print( "Hello\n" )
str=streamSock.read #this line modified
print str
streamSock.close
I know that the streamSock.print is unnecessary (as well as the naming scheme being non-ruby) but I don't understand why read doesn't work while recv does, Why is this?
