Node.js server.setTicketKeys()用法及代碼示例

server.setTicketKeys(keys)是tls模塊內Socket類的內置應用程序編程接口，用於設置包含會話票證 key 的48字節緩衝區。

用法:

server.setTicketKeys(keys)

參數：此方法接受包含會話票證 key 的48字節緩衝區作為參數。

返回值：此方法無返回值。

如何生成私鑰和公共證書？

私鑰：打開記事本並複製粘貼以下 key ：

將文件另存為private-key.pem

公開證書：打開記事本並複製粘貼以下 key ：

將文件另存為public-cert.pem

範例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(); 
});

輸出：

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>
new Session key :

I’m listening at 127.0.0.1, on port 1337

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

範例2： 文件名：index.js

// Node.js program to demonstrate the

    // Stopping the server

    server.close(); 
}); 
  
var buf = Buffer.from([ 
    0x11, 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 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(); 
});

使用以下命令運行index.js文件：

node index.js

輸出：

I'm listening at 127.0.0.1, on port 1337

Received:Session key:17
