Node.js http.ClientRequest.maxHeadersCount API

http.ClientRequest.maxHeadersCount是 http 模块中 ClientRequest 类的内置应用程序编程接口,用于获取最大响应头计数限制。

句法:

const request.maxHeadersCount

参数:此API不接受任何参数作为参数。

返回值:此方法返回最大响应标头计数限制。

index.js
// Node.js program to demonstrate the  
// request.maxHeadersCount APi
  
// 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 clinet request
  const req = http.request(options);
  
  req.maxHeadersCount = 200
  
  // getting maxHeadersCount
  // by using maxHeadersCount api
  const v = req.maxHeadersCount;
  
  // display the result
  console.log("maxHeadersCount :- " + v)
  
  process.exit(0)
});
