js里的list传到后台

// 假设有一个数组需要发送到后台
let list = [1, 2, 3, 4, 5];

// 使用Fetch API发送POST请求
fetch('/api/uploadList', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json'
    },
    body: JSON.stringify(list)
})
.then(response => response.json())
.then(data => console.log('Success:', data))
.catch((error) => console.error('Error:', error));

const express = require('express');
const app = express();
app.use(express.json()); // 解析JSON格式的请求体

app.post('/api/uploadList', (req, res) => {
    let list = req.body;
    console.log('Received list:', list);
    // 这里可以进行数据处理或其他操作
    res.json({ message: 'List received successfully', data: list });
});

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