在ruby中发送和接收TCP数据

Question

我有一个TCP服务器运行,接受命令"GETHELLO"并返回"HELLO".我在linux shell中使用Telnet测试它:

:~$ telnet 192.168.1.10 3000
Trying 192.168.1.10...
Connected to 192.168.1.10.
Escape character is '^]'.
GETHELLO
HELLO

如何使用TCPSocket在ruby中执行此操作？(发送"GETHELLO"并读取服务器返回的数据"HELLO")

谢谢!

Answer 1

require 'socket'
sock = TCPSocket.new('192.168.1.10', 3000)
sock.write 'GETHELLO'
puts sock.read(5) # Since the response message has 5 bytes.
sock.close
