Node.js http.ClientRequest.setNoDelay() 方法

http.ClientRequest.setNoDelay()是 HTTP 模块中 ClientRequest 类的内置应用程序编程接口，用于设置套接字，例如在不希望限制请求的情况下延迟过多的请求。

句法：

const request.setNoDelay([noDelay])

参数：此方法将布尔值作为参数。

返回值：此方法没有任何返回值。

示例 1：文件名-index.js

Javascript

// Node.js program to demonstrate the 
// request.setNoDelay() method
 
// Importing http module
const http = require('http');
 
// Create an HTTP server
const server = http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('okay');
});
 
// Now that server is running
server.listen(3000, '127.0.0.1', () => {
 
  // Make a request
  const options = {
    port: 3000,
    host: '127.0.0.1',
    headers: {
      'Connection': 'Upgrade',
      'Upgrade': 'websocket'
    }
  };
 
  // Getting client request
  const req = http.request(options);
 
  req.host = '127.0.0.1'
 
  // Setting the nodelay for the socket
  // by using setNoDelay method
  req.setNoDelay(true);
 
  // Display the result
  console.log("no delay is set")
 
  process.exit(0)
});

使用以下命令运行index.js文件：

node index.js

输出：

no delay is set

示例 2：文件名-index.js

Javascript

// Node.js program to demonstrate the 
// request.setNoDelay() method
 
// Importing http module
const http = require('http');
 
// Create an HTTP server
http.createServer((req, res) => {}).listen(3000, '127.0.0.1', () => {
 
  // Getting client request
  const req = http.request({
    port: 3000,
    host: '127.0.0.1',
  });
 
  // Setting the nodelay for the socket
  // by using setNoDelay method
  req.setNoDelay(true);
 
  // Display the result
  console.log("no delay is set")
 
  process.exit(0)
});

使用以下命令运行index.js文件：

node index.js

输出：

no delay is set
