Node.js server.getTicketKeys()用法及代码示例

server.getTicketKeys()是tls模块中Socket类的内置应用程序编程接口，用于获取包含会话票证 key 的48字节缓冲区。

用法:

const server.getTicketKeys()

参数：此方法不接受任何参数。

返回值：此方法返回一个包含会话票证 key 的48字节缓冲区。

如何生成私钥和公共证书？

私钥：打开记事本并复制粘贴以下 key ：

将文件另存为private-key.pem

公开证书：打开记事本并复制粘贴以下 key ：

将文件另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// server.close() method 
  
var tls = require('tls'), 
    fs = require('fs'), 
  
// Port and host address for server     
PORT = 1337, 
HOST = '127.0.0.1'; 
   
// 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(); 
  
}); 
  
// Getting session key  
// by using getTicketKeys() method 
const value1 = server.getTicketKeys(); 
console.log(value1) 
  
// Close event 
server.on('close', () => { 
  console.log("Server closed successfully"); 
}) 
  
// Start listening on a specific port and address 
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 the bound address  
  // by using address method 
  const value = client.address(); 
  client.write("Bound address:" + value) 
  client.end(); 
});

输出：

<Buffer 72 59 e4 89 85 0f ae fb eb e6 cb 3a 1a bf 92 19 2f ab 97 be 5d 10 19 50 cc 0f 98 d3 27 fe 9c 68 2a 31 f3 e8 17 b7 77 38 88 f0 28 64 90 1c 36 40>
I’m listening at 127.0.0.1, on port 1337

Received:Bound address:[object Object]
Server closed successfully

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// server.close() 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()); 
  }); 
  
  // Stopping the server 
  // by using the close() method 
  server.close(); 
}); 
  
// getting session key  
// by using getTicketKeys() method 
value = server.getTicketKeys(); 
  
// Start listening on a specific port and address 
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() { 
  client.write("Session key:" + value[0]) 
  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

Received:Session key:222
