Node.js http.IncomingMessage.aborted用法及代码示例

http.IncomingMessage.aborted是HTTP模块中IncomingMessage类的内置应用程序编程接口，用于检查请求是否已中止。

用法:

const message.aborted

参数：此方法不接受任何参数作为参数。

返回值：当且仅当请求被中止时，此方法返回true。

范例1： 文件名：index.js

Javascript

// Node.js program to demonstrate the   
// request.aborted Method  
  
// 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 request is aborted or not 
  // by using request.aborted method 
  const value = request.aborted; 
  
  // Display result 
  response.end("request has been aborted:"
        + value, 'utf8', () => { 
    console.log("displaying the result..."); 
  
    httpServer.close(() => { 
      console.log("server is closed") 
    }) 
  }); 
}); 
  
// Listening to http Server  
httpServer.listen(PORT, () => { 
  console.log("Server is running at port 3000..."); 
});

使用以下命令运行index.js文件。

node index.js

输出：

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

现在，在浏览器中转到http：//localhost：3000 /，您将看到以下输出：

request has been aborted:false

范例2： 文件名：index.js

Javascript

// Node.js program to demonstrate the   
// request.aborted Method  
  
// Importing http module  
var http = require('http'); 
  
// Request and response handler  
const http2Handlers = (request, response) => { 
  
  // Checking if request is aborted or not 
  // by using request.aborted method 
  const value = request.aborted; 
  
  // Display result 
  response.end("request has been aborted:"
        + value, 'utf8', () => { 
    console.log("Writing remotefamily of socket..."); 
  
    httpServer.close(() => { 
      console.log("server is closed") 
    }) 
  }); 
}; 
  
// Creating http Server  
var httpServer = http.createServer( 
  http2Handlers).listen(3000, () => { 
  console.log("Server is running at port 3000..."); 
});

使用以下命令运行index.js文件。

node index.js

输出：

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

现在，在浏览器中转到http：//localhost：3000 /，您将看到以下输出：

request has been aborted:false
