Node.js server.setTicketKeys()用法及代码示例

server.setTicketKeys(keys)是tls模块内Socket类的内置应用程序编程接口，用于设置包含会话票证 key 的48字节缓冲区。

用法:

server.setTicketKeys(keys)

参数：此方法接受包含会话票证 key 的48字节缓冲区作为参数。

返回值：此方法无返回值。

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 
var value1 = server.getTicketKeys(); 
console.log("old Session key :") 
console.log(value1) 
  
var buf = Buffer.from([ 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff, 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff, 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff, 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff, 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff, 
    0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0xff, 0xff,]); 
  
// Setting up the new session key 
// by using setTicketKeys() method 
server.setTicketKeys(buf) 
  
// Getting session key  
// by using getTicketKeys() method 
var value1 = server.getTicketKeys(); 
console.log("new Session key :") 
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：

old Session key :
<Buffer 5a b5 7a 5e d4 f0 29 93 f6 dd 2e 1d d3 7c b9 30 2a 7e 4e 09 17 8c 32 0e d0 b2 6d fd ed 40 c1 ab d1 20 9a 57 1d e4 f4 ad 44 45 54 0b fd cf fd 99>

// 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:17
