示例 1: 文件名:index.js
// Node.js program to demonstrate the
// tlsSocket.getFinished() 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 finished message digest
// by using tlsSocket.getFinished() method
value = client.getFinished();
client.write("Finisher message : " + value.toJSON().data);
client.end(() => {
console.log("Client closed successfully");
});
});
使用以下命令运行 index.js 文件:
node index.js
输出:
