Node.js tls.createServer()方法
原文:https://www . geesforgeks . org/node-js-TLS-createserver-method/
tls.createServer() 是 tls 模块中类 tls 的内置应用程序编程接口，用于创建 TLS。服务器对象。
语法:
const tls.createServer([options][, secureConnectionListener])
参数:该方法以下列参数为参数:
-
选项:可以根据需要使用 enableTrace、主机、端口、路径、套接字、allowHalfOpen、rejectUnauthorized、pskCallback、ALPNProtocols 等属性选项。
-
secureConnectionListener:是控制服务器实例的功能。
返回值:该方法返回 tls.Server 的对象。

现在将文件名保存为公共证书
示例 1: 文件名:index.js
// Node.js program to demonstrate the
// tls.createServer() 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
// by using tls.createServer() method
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
// by using tls.connect() method
var client = tls.connect(PORT, HOST, options, function() {
// Setting maximum send fragment limit
// by using tlsSocket.setMaxSendFragment() method
value = client.setMaxSendFragment(16384);
if(value)
client.write("tls fragment is set");
else
client.write("tls fragment is not set")
client.end(() => {
console.log("Client closed successfully");
});
});
使用以下命令运行 index.js 文件:
node index.js
输出:
I'm listening at 127.0.0.1, on port 1337
Client closed successfully
Received: tls fragment is set
Server closed successfully

// Close the connection after receiving the message

});
使用以下命令运行 index.js 文件:
node index.js
输出:
I'm listening at 127.0.0.1, on port 1337
client is connected
Received: tls fragment is set
client closed successfully
Server closed successfully
