Node.js tls.createServer()用法及代碼示例

tls.createServer()是tls模塊內的TLS類的內置應用程序編程接口，用於創建tls.Server對象。

用法:

const tls.createServer([options][, secureConnectionListener])

參數：此方法將以下參數作為參數：

選項：可以根據需要使用諸如enableTrace，主機，端口，路徑，套接字，allowHalfOpen，拒絕未經授權，pskCallback，ALPNProtocols等屬性。
secureConnectionListener：它是用於控製服務器實例的函數。

返回值：此方法返回tls.Server的對象。

如何生成私鑰和公證書？

私鑰：打開記事本並複製粘貼以下 key ：

現在將文件名另存為private-key.pem

公開證書：打開記事本並複製粘貼以下 key ：

現在將文件名另存為public-cert.pem

範例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"); 
  }); 
});

使用以下命令運行index.js文件：

node index.js

輸出：

I'm listening at 127.0.0.1, on port 1337
Client closed successfully

Received:tls fragment is set
Server closed successfully

範例2： 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'; 
   
// 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() api 
var server = tls.createServer(options, function(socket) { 
  
  // Setting maximum send fragment limit 
  // by using tlsSocket.setMaxSendFragment() method 
  value = socket.setMaxSendFragment(16384); 
  
  if(value) 
    socket.write("tls fragment is set"); 
  else
    socket.write("tls fragment is not set") 
  
  // 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() { 
   console.log("client is connected"); 
}); 
  
client.on("data", function(data) { 
  
  console.log('Received:%s', 
  data.toString().replace(/(\n)/gm, "")); 
  
  // Close the connection after receiving the message 
  client.end(() => { 
     console.log("client closed successfully") 
  }); 
});

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
client is connected
Received:tls fragment is set
client closed successfully
Server closed successfully
