Node.js server.setSecureContext()用法及代码示例

server.setSecureContext()是tls模块中Socket类的内置应用程序编程接口，用于替换现有服务器的安全上下文。

用法:

server.setSecureContext(options)

参数：该方法采用tls.createSecureContext()选项参数中的任何可能的属性。

返回值：此方法不返回任何内容。

如何生成私钥和公共证书？

私钥：打开记事本并复制粘贴以下 key ：

将文件另存为private-key.pem

公开证书：打开记事本并复制粘贴以下 key ：

将文件另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// server.setSecureContext() method 
  
const { Console } = require('console'); 
  
// Server.setSecureContext()  API 
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, "")); 
  }); 
  
  // Replacing secure context with the new one 
  server.setSecureContext(options.cert); 
  console.log("secure replaced sucssesfully"); 
  
  server.close(); 
}); 
  
// 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); 
}); 
  
  
// When an error occurs, show it. 
server.on("error", function(error) { 
  console.error(error); 
}); 
  
  
// Creating and initializing client 
var client = tls.connect(PORT,  
      HOST, options, function() { 
  
  // Check if the authorization worked 
  if (client.authorized) { 
     console.log("Connection authorized "
        + "by a Certificate Authority."); 
  } else { 
     console.log("Connection not authorized:" 
        + client.authorizationError) 
  } 
  
  // Send a friendly message 
  client.write("I am the client sending"
            + " you a message."); 
  client.end(); 
}); 
  
client.on("close", function() { 
  console.log("Connection closed"); 
}); 
  
// When an error occurs, show it. 
client.on("error", function(error) { 
  
  console.error(error); 
  
  // Close the connection after  
  // the error occurred. 
  client.destroy(); 
});

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
Connection not authorized:DEPTH_ZERO_SELF_SIGNED_CERT
secure replaced sucssesfully

Received:I am the client sending you a message.
Connection closed

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// server.setSecureContext() 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, "")); 
  }); 
  
  // Replacing secure context with the new one 
  server.setSecureContext(options.cert); 
  console.log("secure replaced successfully"); 
  
  server.close(); 
}); 
  
// 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() { 
  
  // Send a friendly message 
  client.write("I am the client sending you a message."); 
  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
secure replaced successfully

Received:I am the client sending you a message.
