Node.js tlsSocket.address()用法及代码示例

tlsSocket.address()方法是tls模块内TLSSocket类的内置应用程序编程接口，用于获取绑定地址，地址族名称和基础套接字的端口。

用法:

const tlsSocket.address()

参数：此方法不接受任何参数。

返回值：此方法返回绑定地址，地址族名称和基础套接字的端口。

如何生成私钥和公共证书？

私钥
第1步：打开记事本并复制粘贴以下 key ：

步骤2：另存为private-key.pem

公开证书
第1步：打开记事本并复制粘贴以下 key ：

步骤2：另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// tlsSocket.address() 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 acess 
var options = { 
  key:fs.readFileSync('private-key.pem'), 
  cert:fs.readFileSync('public-cert.pem'), 
  rejectUnauthorized:false
}; 
  
// Creating and intializing 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, "")); 
  }); 
  
  // Getting the bound address of the socket 
  // by using tlsSocket.address() method 
  value = socket.address(); 
  console.log("Address:" + value.address); 
  
  // Stopping the server 
  // by using the close() method 
  server.close(); 
}); 
  
// Close event 
server.on('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 intializing 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.family) 
  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
Address:127.0.0.1

Received:Bound address:IPv4
Server closed successfully

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// tlsSocket.address() 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 acess 
var options = { 
  key:fs.readFileSync('private-key.pem'), 
  cert:fs.readFileSync('public-cert.pem'), 
  rejectUnauthorized:false
}; 
  
// Creating and intializing server 
var server = tls.createServer(options, function(socket) { 
  
  // Getting the bound address of the socket 
  // by using tlsSocket.address() method 
  const value = socket.address(); 
  
  socket.write("Address:" + value.family); 
  
  // Stopping the server 
  // by using the close() method 
  server.close(); 
  
}); 
  
// Close event 
server.on('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 intializing client 
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:Address:IPv4
client closed successfully
Server closed successfully
