function connect
#connect(options: ConnectionOptions,secureConnectListener?: () => void,): TLSSocketThe callback function, if specified, will be added as a listener for the 'secureConnect' event.
tls.connect() returns a TLSSocket object.
Unlike the https API, tls.connect() does not enable the
SNI (Server Name Indication) extension by default, which may cause some
servers to return an incorrect certificate or reject the connection
altogether. To enable SNI, set the servername option in addition
to host.
The following illustrates a client for the echo server example from createServer:
// Assumes an echo server that is listening on port 8000.
import tls from 'node:tls';
import fs from 'node:fs';
const options = {
// Necessary only if the server requires client certificate authentication.
key: fs.readFileSync('client-key.pem'),
cert: fs.readFileSync('client-cert.pem'),
// Necessary only if the server uses a self-signed certificate.
ca: [ fs.readFileSync('server-cert.pem') ],
// Necessary only if the server's cert isn't for "localhost".
checkServerIdentity: () => { return null; },
};
const socket = tls.connect(8000, options, () => {
console.log('client connected',
socket.authorized ? 'authorized' : 'unauthorized');
process.stdin.pipe(socket);
process.stdin.resume();
});
socket.setEncoding('utf8');
socket.on('data', (data) => {
console.log(data);
});
socket.on('end', () => {
console.log('server ends connection');
});
