Node.js http.server.keepAliveTimeout用法及代碼示例

http.server.keepAliveTimeout是http模塊中Server類的內置應用程序編程接口，用於獲取服務器等待其他傳入數據所需的非活動毫秒數。

用法:

server.keepAliveTimeout

參數：此Api不接受任何參數作為參數。

返回值：此方法返回服務器等待其他傳入數據所需的不活動毫秒數。

示例1：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// server.keepAliveTimeout property 
    
// Importing http module  
var http = require('http');  
    
// Setting up PORT  
const PORT = process.env.PORT || 3000;  
    
// Creating http Server  
var httpServer = http.createServer( 
  function(request, response){  
  
  // Getting the reference of the 
  // underlying socket object 
  // by using socket API 
  const value = response.socket; 
    
  // Display result 
  // by using end() api 
  response.end( "Socket buffersize:" 
      + value.bufferSize, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing server  
      // by using close() api 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  });  
});  
    
// Listening to http Server  
// by using listen() api 
httpServer.listen(PORT, () => {  
    console.log("Server is running at port 3000...");  
}); 
  
// Getting keep alive timeout value 
// by using keepAliveTimeout api 
const v = httpServer.keepAliveTimeout 
  
// Display the result 
console.log('keep alive time out value:-' + v)

使用以下命令運行index.js文件：

node index.js

控製台輸出：

keep alive time out value:-5000
Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

瀏覽器輸出：在瀏覽器的搜索欄中粘貼本地主機地址http：//localhost：3000 /。

Socket buffersize:0

示例2：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// server.keepAliveTimeout property 
    
// Importing http module  
var http = require('http');  
  
// Request and response handler  
const http2Handlers = (request, response) => {  
    
  // Getting the reference of the 
  // underlying socket object 
  // by using socket API 
  const value = response.socket; 
    
  // Display result 
  // by using end() api 
  response.end( "Socket local address:" 
      + value.localAddress, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing server  
      // by using close() api 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  }); 
};  
    
// Listening to http Server  
// by using listen() api 
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");  
});  
  
// Getting keep alive timeout value 
// by using keepAliveTimeout property 
const v = httpServer.keepAliveTimeout 
  
// Display the result 
console.log('keep alive time out value:-' + v)

使用以下命令運行index.js文件：

node index.js

控製台輸出：

keep alive time out value:-5000
Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

瀏覽器輸出：在瀏覽器的搜索欄中粘貼本地主機地址http：//localhost：3000 /。

Socket local address:::1
