js怎么获取request

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        console.log(xhr.responseText);
    }
};
xhr.send();

fetch('https://api.example.com/data')
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));

const http = require('http');

const options = {
    hostname: 'api.example.com',
    port: 80,
    path: '/data',
    method: 'GET'
};

const req = http.request(options, res => {
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', chunk => {
        console.log(`BODY: ${chunk}`);
    });
    res.on('end', () => {
        console.log('No more data in response.');
    });
});

req.on('error', error => {
    console.error(`problem with request: ${error.message}`);
});

req.end();

npm install axios

const axios = require('axios');

axios.get('https://api.example.com/data')
    .then(response => {
        console.log(response.data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

const express = require('express');
const app = express();

app.get('/data', (req, res) => {
    console.log(req.method); // GET
    console.log(req.url);   // /data
    res.send('Hello World!');
});

app.listen(3000, () => {
    console.log('Server is running on port 3000');
});
