Receive a Line Terminated by CRLF

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveToCRLF, which receives text through a CRLF line terminator and returns the text including the terminator.

llSuccess = .F.

loSocket = createobject("CkSocket")

//  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.
llBTls = .T.
lnMaxWaitMs = 5000
llSuccess = loSocket.Connect("example.com",5000,llBTls,lnMaxWaitMs)
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

//  StringCharset controls the character encoding used when sending and receiving text.
loSocket.StringCharset = "utf-8"
//  Send a request using a simple application-defined text protocol in which each message ends with a
//  CRLF.
lcCommand = "STATUS" + Chr(13) + Chr(10)
llSuccess = loSocket.SendString(lcCommand)
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

//  Receive text through a CRLF line terminator, returning the text including the terminator.  This is
//  convenient for line-oriented text protocols in which each response is a CRLF-terminated line.
lcResponseLine = loSocket.ReceiveToCRLF()
if (loSocket.LastMethodSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
