SSL Client Example

See more Socket/SSL/TLS Examples

Demonstrates how to connect to an SSL server, send a simple message, receive a simple response, and disconnect. Swift

func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let socket = CkoSocket()!

    var ssl: Bool = true
    var maxWaitMillisec: Int = 20000

    // The SSL server hostname may be an IP address, a domain name,
    // or "localhost".  You'll need to change this:
    var sslServerHost: String?
    sslServerHost = "123.123.88.88"
    var sslServerPort: Int = 8123

    // Connect to the SSL server:
    success = socket.connect(hostname: sslServerHost, port: sslServerPort, ssl: ssl, maxWaitMs: maxWaitMillisec)
    if success != true {
        print("\(socket.lastErrorText!)")
        return
    }

    // Set maximum timeouts for reading an writing (in millisec)
    socket.maxReadIdleMs = 20000
    socket.maxSendIdleMs = 20000

    // Send a "Hello Server! -EOM-" message:
    success = socket.sendString(str: "Hello Server! -EOM-")
    if success != true {
        print("\(socket.lastErrorText!)")
        return
    }

    // The server (in this example) is going to send a "Hello Client! -EOM-" 
    // message.  Read it:
    var receivedMsg: String? = socket.receive(untilMatch: "-EOM-")
    if socket.lastMethodSuccess != true {
        print("\(socket.lastErrorText!)")
        return
    }

    // Close the connection with the server
    // Wait a max of 20 seconds (20000 millsec)
    success = socket.close(maxWaitMs: 20000)

    print("\(receivedMsg!)")
