send a message to a tcp server in ruby

To send a message to a TCP server in Ruby, we need to use the socket library which provides low-level access to the networking stack.

Here's an example of how to send a message to a TCP server in Ruby:

main.rb
require 'socket'

# TCP server connection details
server_host = 'localhost'
server_port = 12345

# Message to send
message = 'Hello TCP server!'

# Connect to the TCP server
socket = TCPSocket.new(server_host, server_port)

# Send the message to the TCP server
socket.puts(message)

# Close the connection
socket.close
319 chars
18 lines

In this example, we first specify the TCP server connection details - the hostname and port number. We then define the message that we want to send to the server.

Next, we use the TCPSocket class to establish a connection to the server. We create a new instance of TCPSocket by passing the server hostname and port number as arguments.

We then use the puts method to send the message to the server. Finally, we close the connection by calling the close method on the socket object.

Note that if the server does not receive the full message after calling puts, you might want to consider calling flush on the socket object after puts.
