Receive Text up to a Matching Sequence

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatch, which receives bytes until an exact byte sequence is found. The match string is encoded using StringCharset and compared byte-for-byte.

require 'chilkat'

success = false

socket = Chilkat::CkSocket.new()

#  Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
#  connection succeeds; the 4th is the maximum time to wait, in milliseconds.
bTls = true
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  StringCharset controls the character encoding used when sending and receiving text.
socket.put_StringCharset("utf-8")
#  Send a request using a simple application-defined text protocol in which each message ends with a
#  CRLF.
command = "STATUS\r\n"
success = socket.SendString(command)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  Receive bytes until an exact byte sequence is found.  The match string is encoded using
#  StringCharset and compared byte-for-byte.  Here the server marks the end of its response with an
#  application-defined marker.
response = socket.receiveUntilMatch("<EOM>")
if (socket.get_LastMethodSuccess() == false)
    print socket.lastErrorText() + "\n";
    exit
end

print response + "\n";
