Node.js http.ServerResponse.sendDate用法及代码示例

httpServerResponse.sendDate是http模块中服务器响应类的内置应用程序编程接口，用于检查日期头是否已发送。 HTTP标头还用于传递其他信息，例如Date等。请参阅本文。

用法:

response.sendDate

参数：此方法不接受任何参数作为参数。

返回值：当且仅当发送了日期标头时，此方法才返回true。

示例1：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// response.sendDate() APi 
    
// 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){  
  
  // Checking if date header has been 
  // sent or not by using sendDate API 
  const value = response.sendDate; 
    
  // Display result 
  // by using end() api 
  response.end( "Date header status:" 
    + value, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing the server 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  });  
});  
    
// Listening to http Server  
httpServer.listen(PORT, () => {  
    console.log("Server is running at port 3000...");  
});

执行命令：

node index.js

控制台输出：

Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

浏览器输出：粘贴localhost地址http：//localhost：3000 /。在浏览器的搜索栏中。

Date header status:true

示例2：Filename：index.js

Javascript

// Node.js program to demonstrate the   
// response.sendDate() APi 
    
// Importing http module  
var http = require('http');  
  
// Request and response handler  
const http2Handlers = (request, response) => {  
    
  // Checking if date header has been 
  // sent or not by using sendDate API 
  const value = response.sendDate; 
    
  // Display result by using end() api 
  response.end( "Date header status:"
    + value, 'utf8', () => {  
      console.log("displaying the result...");  
  
      // Closing the server 
      httpServer.close(()=>{ 
          console.log("server is closed") 
      }) 
  }); 
};  
    
// Creating http Server and listening 
// on the port 3000 
var httpServer = http.createServer( 
    http2Handlers).listen(3000, () => {  
    console.log("Server is running at port 3000...");  
});

执行命令：

node index.js

控制台输出：

Server is running at port 3000...
displaying the result...
displaying the result...
server is closed
server is closed

浏览器输出：粘贴localhost地址http：//localhost：3000 /。在浏览器的搜索栏中。
