(Go) TCP/IP Socket Connect to Remote Host:PortDemonstrates how to create a TCP/IP socket, connect to a remote host:port, and receive a "Hello World!" message.
// 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: // http://www.cknotes.com/?p=302 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() |
