How to send requests to the intermediate service layer in node (detailed tutorial)

How does node send requests as an intermediate service layer? The editor below will share with you the implementation method of sending requests, which has a good reference value and I hope it will be helpful to everyone

GET request:

var http = require('http'); 
var qs = require('querystring'); 
var data = { 
  a: 123, 
  time: new Date().getTime()};//这是需要提交的数据 
var content = qs.stringify(data); 
var options = { 
  hostname: '127.0.0.1', 
  port: 10086, 
  path: '/pay/pay_callback?' + content, 
  method: 'GET' 
}; 
  
var req = http.request(options, function (res) { 
  console.log('STATUS: ' + res.statusCode); 
  console.log('HEADERS: ' + JSON.stringify(res.headers)); 
  res.setEncoding('utf8'); 
  res.on('data', function (chunk) { 
    console.log('BODY: ' + chunk); 
  }); 
}); 
  
req.on('error', function (e) { 
  console.log('problem with request: ' + e.message); 
}); 
  
req.end();

POST request:

var http = require('http'); 
var qs = require('querystring'); 
var post_data = { 
  a: 123, 
  time: new Date().getTime()};//这是需要提交的数据 
var content = qs.stringify(post_data); 
var options = { 
  hostname: '127.0.0.1', 
  port: 10086, 
  path: '/pay/pay_callback', 
  method: 'POST', 
  headers: { 
    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' 
  } 
}; 
  
var req = http.request(options, function (res) { 
  console.log('STATUS: ' + res.statusCode); 
  console.log('HEADERS: ' + JSON.stringify(res.headers)); 
  res.setEncoding('utf8'); 
  res.on('data', function (chunk) { 
    console.log('BODY: ' + chunk); 
  }); 
}); 
  
req.on('error', function (e) { 
  console.log('problem with request: ' + e.message); 
}); 
// write data to request body 
req.write(content); 
req.end();

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
