TCP/IP Socket Connect to Remote Host:Port

See more Socket/SSL/TLS Examples

Demonstrates how to create a TCP/IP socket, connect to a remote host:port, and receive a "Hello World!" message. Go

    success := false

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

    socket := chilkat.NewSocket()

    // Connect to port 5555 of localhost.
    // The string "localhost" is for testing on a single computer.
    // It would typically be replaced with an IP hostname, such
    // as "www.chilkatsoft.com".
    ssl := false
    maxWaitMillisec := 20000
    success = socket.Connect("localhost",5555,ssl,maxWaitMillisec)
    if success != true {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

    // Set maximum timeouts for reading an writing (in millisec)
    socket.SetMaxReadIdleMs(10000)
    socket.SetMaxSendIdleMs(10000)

    // Pretend, for the sake of the example, that the
    // ficticious server is going to send a "Hello World!" 
    // after accepting the connection.  
    // Note: Technically, the ReceiveString may not receive the
    // complete string, although it's highly probable given the short
    // length of the "Hello World!" message. 
    // See this Chilkat blog post for more information:

    receivedMsg := socket.ReceiveString()
    if socket.LastMethodSuccess() != true {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

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

    fmt.Println(*receivedMsg)

    socket.DisposeSocket()
