Node.js server.close()用法及代码示例


server.close()是tls模块中Socket类的内置应用程序编程接口,用于阻止服务器接受新的客户端请求。

用法:

const server.close()

参数:此方法不接受任何参数。

返回值:此方法只返回用于侦听服务器实例的回调函数。

如何生成私钥和公共证书?



  1. 私钥:打开记事本并复制粘贴以下 key :
    -----BEGIN RSA PRIVATE KEY-----
    MIICXQIBAAKBgQC38R9wXcUbhOd44FavgmE5R3K4JeYOHLnI7dUq1B8/Gv7l3SOg

    nUG9lYvH7DztWDTioXMrruPF7bdXfZOVJD8t0I4OUzvC
    -----END RSA PRIVATE KEY-----

    将文件另存为private-key.pem

  2. 公开证书:打开记事本并复制粘贴以下 key :
    -----BEGIN CERTIFICATE-----
    MIICfzCCAegCCQDxxeXw914Y2DANBgkqhkiG9w0BAQsFADCBgzELMAkGA1UEBhMC

    -----END CERTIFICATE-----

    将文件另存为public-cert.pem

范例1: 文件名:index.js

// Node.js program to demonstrate the 
// server.close() 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, "")); 
  }); 
  
  // Stopping the server 
  // by using the close() method 
  server.close(()=>{ 
    console.log("server closed successfully"); 
  }) 
}); 
  
  
// 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() {   
  // Getting the bound address  
  // by using address method 
  const value = client.address(); 
  client.write("Bound address:" + value); 
  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

Received:Bound address:[object Object]
server closed successfully

范例2: 文件名:index.js

// Node.js program to demonstrate the 
// server.close() 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, "")); 
  }); 
  
  // 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 
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() { 
    
  // Getting the bound address  
  // by using address method 
  const value = client.address(); 
  client.write("Bound address:" + value) 
  
  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

Received:Bound address:[object Object]
Server closed successfully
