Node.js tlsSocket.enableTrace()用法及代码示例

tlsSocket.enableTrace()方法是tls模块内的TLSSocket类的内置应用程序编程接口，用于调试TLS连接问题。

用法:

tlsSocket.enableTrace()

参数：此方法不接受任何参数。

返回值：此方法将在stderr中显示TLS数据包跟踪信息。

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.enableTrace() 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, "")); 
  }); 
  
  // 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 intializing client 
var client = tls.connect(PORT, HOST, options, function() { 
    
  // Display TLS packet trace information  
  // by using tlsSocket.disableRenegotiation() method 
  client.enableTrace(); 
  
  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
