Node.js tls.rootCertificates()用法及代码示例

tls.rootCertificates()方法是tls模块内TLS类的内置应用程序编程接口，用于返回表示根证书的字符串数组。

用法:

const tls.rootCertificates()

参数：此方法不接受任何参数。

返回值：此方法返回代表根证书的字符串数组。

如何生成私钥和公证书？

私钥：打开记事本并复制粘贴以下 key ：

现在将文件名另存为private-key.pem

公开证书：打开记事本并复制粘贴以下 key ：

现在将文件名另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// tls.rootCertificates 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 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() { 
    
  // Getting list of root certificte 
  // by using tls.rootCertificates method 
  value = tls.rootCertificates; 
  
  client.write(" rootCertificates:" + value[0]); 
    
  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 closed successfully

Received: rootCertificates:-----BEGIN CERTIFICATE-----MIIDq......
WFACSCZLg==-----END CERTIFICATE-----
Server closed successfully

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// tls.rootCertificates 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 intializing server 
var server = tls.createServer(options, function(socket) { 
  
  // Getting list of root certificte 
  // by using tls.rootCertificates method 
  value = tls.rootCertificates; 
  
  socket.write(" rootCertificates:" + value[0]); 
  
  // 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() { 
   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: rootCertificates:-----BEGIN CERTIFICATE
           ---- MIIDqDCCApC..........r1Uw
njvVNioZBPRcHv/PLLf//qu0bXu+TZLg==-----END CERTIFICATE-----
client closed successfully
Server closed successfully
