Ruby TCP套接字从未收到回复

我使用TCP连接并发送如下数据：

begin
  session = "mysession"
  socket = TCPSocket.new(tcpaddress, port)
  socket.setsockopt(Socket::IPPROTO_TCP, Socket::TCP_NODELAY, 1)
  puts "sending to socket HELO " + session
  socket.write ('HELO ' + session)
  puts socket.read
  socket.close
rescue Exception => myException
   puts "Exception rescued : #{myException}"
end

套接字从未收到回复，但telnet会：

$ telnet some_ip port
Trying some_ip...
Connected to some_ip
Escape character is '^]'.
HELO mysession
OK

正如您所看到的，远程服务器按预期回复“OK”。怎么了

提前感谢

PS：我也使用了puts和send方法

也许您需要将CRLF添加到命令中：

socket.write("HELO " + session + "\r\n")

我有几乎相同的问题。是的，那就修好了，谢谢
