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.

local chilkat = require("chilkat")

local socket = chilkat.Socket.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.
local bTls = true
local maxWaitMs = 5000
local success = socket:connect("example.com", 5000, bTls, maxWaitMs)
if not success then
    print(socket.last_error_text)
    return
end

-- StringCharset controls the character encoding used when sending and receiving text.
socket.string_charset = "utf-8"
-- Send a request using a simple application-defined text protocol in which each message ends with a
-- CRLF.
local command = "STATUS\r\n"
success = socket:send_string(command)
if not success then
    print(socket.last_error_text)
    return
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.
local response = socket:receive_until_match("<EOM>")
if not socket.last_method_success then
    print(socket.last_error_text)
    return
end

print(response)
