- Ahora guarde el nombre del archivo como public-cert.pem
Ejemplo 1: Nombre de archivo: index.js
javascript
// Node.js program to demonstrate the
// tlsSocket.remoteFamily method
var tls = require('tls'),
fs = require('fs'),
// Port and host address for server
PORT = 1337,
HOST = '127.0.0.1',
value = null;
// Private key and public certificate for access
var options = {
key: fs.readFileSync('private-key.pem'),
cert: fs.readFileSync('public-cert.pem'),
rejectUnauthorized: false
};
// Creating and initializing server
var server = tls.createServer(options, function(socket) {
// Print the data that we received
socket.on('data', function(data) {
console.log('\nReceived: %s ',
data.toString().replace(/(\n)/gm, ""));
});
// Stopping the server
// by using the close() method
server.close(() => {
console.log("Server closed successfully");
});
});
// Start listening on a specific port and address
// by using listen() method
server.listen(PORT, HOST, function() {
console.log("I'm listening at %s, on port %s", HOST, PORT);
});
// Creating and initializing client
var client = tls.connect(PORT, HOST, options, function() {
// Getting remote IP Family
// by using tlsSocket.remoteFamily method
value = client.remoteFamily;
client.write("remoteFamily : " + value);
client.end(() => {
console.log("Client closed successfully");
});
});
Ejecute el archivo index.js con el siguiente comando:
node index.js
Producción:
