js中获取request

fetch('https://api.example.com/data', {
    method: 'GET', // 或者 'POST', 'PUT', 'DELETE' 等
    headers: {
        'Content-Type': 'application/json',
        // 其他头部信息
    },
    // body: JSON.stringify(data), // 仅在POST或PUT请求中使用
})
.then(response => {
    if (!response.ok) {
        throw new Error('Network response was not ok');
    }
    return response.json(); // 或者 response.text() 等
})
.then(data => console.log(data))
.catch(error => console.error('There has been a problem with your fetch operation:', error));

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

app.get('/data', (req, res) => {
    // 获取请求方法
    console.log(req.method); // GET, POST 等

    // 获取请求URL
    console.log(req.url); // /data

    // 获取请求头
    console.log(req.headers);

    // 获取查询参数
    console.log(req.query);

    // 获取请求体（需要使用中间件解析）
    app.use(express.json()); // 解析JSON请求体
    console.log(req.body);

    res.send('Data received');
});

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