Receive a String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveString, which receives text and decodes it using StringCharset. It returns the first nonempty decoded result rather than draining all available data.

func chilkatTest() {
    var success: Bool = false

    let socket = CkoSocket()!

    //  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.
    var bTls: Bool = true
    var maxWaitMs: Int = 5000
    success = socket.connect(hostname: "example.com", port: 5000, ssl: bTls, maxWaitMs: maxWaitMs)
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    //  StringCharset controls the character encoding used when sending and receiving text.
    socket.stringCharset = "utf-8"
    //  Send a request using a simple application-defined text protocol in which each message ends with a
    //  CRLF.
    var command: String? = "STATUS\r\n"
    success = socket.sendString(str: command)
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    //  Receive text and decode it using StringCharset.  ReceiveString returns the first nonempty decoded
    //  result; it does not keep reading to drain all available data.
    var responseText: String? = socket.receiveString()
    if socket.lastMethodSuccess == false {
        print("\(socket.lastErrorText!)")
        return
    }

    print("\(responseText!)")
