Node.js request.writableEnded 属性

request.writableEnded （在 v12.9.0 中添加）属性是“ http ”模块的内置属性，它在request.end()被调用后返回 true。此属性不指示数据是否已刷新，为此使用request.writableFinished代替。

为了得到响应和正确的结果，我们需要导入' http '模块。

句法：

const http = require('http');  

句法：

request.writableEnded 

参数：此属性不接受任何参数。

返回值< Boolean > ： request.end()被调用后返回true。

下面的例子说明了在 Node.js 中request.writableEnded属性的使用。

示例：文件名：index.js

// Node.js program to demonstrate the 
// request.writableEnded property 
  
// Using require to access http module 
const { get } = require('http'); 
  
// Setting host server url 
const options = { host: 'www.geeksforgeeks.org' }; 
  
// Requesting from geeksforgeeks server 
const request = get(options); 
  
console.log("writableEnded:", request.writableEnded);
  
request.end(); 
  
console.log("writableEnded:", request.writableEnded);
  
request.once('response', (res) => { 
  
    // Printing the requestrelated data 
    console.log("Status:", res.statusCode, res.statusMessage); 
    console.log("Writable:", request.socket.writable); 
    console.log("Readable:", request.socket.readable); 
      
    console.log("writableEnded:", request.writableEnded);
  
    // Printing address and port after getting response 
    console.log(`IP address of geeksforgeeks is`,
    ` ${request.socket.localAddress}.`); 
  
    console.log(`Its port is ${request.socket.localPort}.`); 
}); 

使用以下命令运行index.js文件：

node index.js

输出：

writableEnded: true

writableEnded: true

Status: 301 Moved Permanently

Writable: true

Readable: true

writableEnded: true

IP address of geeksforgeeks is 192.168.43.207.

Its port is 64596
