Node.jstls.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。

如何生成私钥和公钥证书？

• Private key: Open notepad and copy paste the following key:

  ```js
  -----BEGIN RSA PRIVATE KEY-----

  现在将文件名保存为私钥




• Public certificate: Open notepad and copy paste the following key:

  ```js
  -----BEGIN CERTIFICATE-----

  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
  client.end(() => {

  });
});


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
