js获得request的值

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

// 解析 application/x-www-form-urlencoded
app.use(express.urlencoded({ extended: false }));
// 解析 application/json
app.use(express.json());

app.post('/your-endpoint', (req, res) => {
    // 获取查询参数
    const queryParams = req.query;
    
    // 获取URL中的参数（例如：/your-endpoint/:id）
    const pathParams = req.params;
    
    // 获取POST请求体中的数据
    const bodyParams = req.body;

    console.log('Query Params:', queryParams);
    console.log('Path Params:', pathParams);
    console.log('Body Params:', bodyParams);

    res.send('Request received!');
});

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

// 使用fetch API发送GET请求
fetch('/your-endpoint?param1=value1&param2=value2')
    .then(response => response.json())
    .then(data => {
        console.log('Response Data:', data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

// 使用fetch API发送POST请求
fetch('/your-endpoint', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json'
    },
    body: JSON.stringify({ key1: 'value1', key2: 'value2' })
})
    .then(response => response.json())
    .then(data => {
        console.log('Response Data:', data);
    })
    .catch(error => {
        console.error('Error:', error);
    });
