(JavaScript) Accept Connection on Socket

Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client.

Note: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var listenSocket = new CkSocket();

// Bind to a port and listen for incoming connections:
// This example will listen at port 5555 and allows for a backlog
// of 25 pending connection requests.
success = listenSocket.BindAndListen(5555,25);
if (success == false) {
    console.log(listenSocket.LastErrorText);
    return;
}

// Get the next incoming connection
// Wait a maximum of 20 seconds (20000 millisec)
var connectedSocket = new CkSocket();
success = listenSocket.AcceptNext(20000,connectedSocket);
if (success == false) {
    console.log(listenSocket.LastErrorText);
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
connectedSocket.MaxReadIdleMs = 10000;
connectedSocket.MaxSendIdleMs = 10000;

// Send a "Hello World!" message to the client:
success = connectedSocket.SendString("Hello World!");
if (success !== true) {
    console.log(connectedSocket.LastErrorText);
    return;
}

// Close the connection with the client.
// Wait a max of 20 seconds (20000 millsec)
success = connectedSocket.Close(20000);

console.log("success!");
