ssm/php/node/python基于HTML5的网上跳蚤市场

由于提供整个项目的源代码和数据库将会涉及到版权和隐私问题，我无法直接提供源代码。但我可以提供一个基本的HTML5页面模板作为示例，以及各种语言编写的后端示例代码。

HTML5页面示例（index.html）:




<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>在线跳蚤市场</title>
</head>
<body>
    <h1>欢迎来到在线跳蚤市场</h1>
    <!-- 页面内容 -->
</body>
</html>

SSM后端示例代码（简化版）:




@Controller
@RequestMapping("/api/v1/market")
public class MarketController {
    @Autowired
    private MarketService marketService;
 
    @GetMapping("/list")
    @ResponseBody
    public ResponseEntity<?> getMarketList() {
        List<MarketItem> list = marketService.getMarketList();
        return ResponseEntity.ok(list);
    }
 
    // 其他API端点...
}

PHP后端示例代码（index.php）:




<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_dbname";
 
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
 
// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
 
$sql = "SELECT * FROM Market";
$result = $conn->query($sql);
 
if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "item_id: " . $row["item_id"]. " - item_name: " . $row["item_name"]. "<br>";
    }
} else {
    echo "0 结果";
}
$conn->close();
?>

Node.js后端示例代码（app.js）:




const express = require('express');
const mysql = require('mysql');
 
const app = express();
 
const connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'your_username',
  password : 'your_password',
  database : 'your_dbname'
});
 
connection.connect();
 
app.get('/api/v1/market/list', (req, res) => {
  connection.query('SELECT * FROM Market', (error, results, fields) => {
    if (error) throw error;
    res.send(results);
  });
});
 
app.listen(3000, () => {
  console.log('服务器运行在 http://localhost:3000/');
});

Python后端示例代码（app.py）:




import mysql.connector
from flask import Flask, jsonify
 
app = Flask(__name__)
 
@app.route('/api/v1/market/list')
def get_market_list():
    db_connection = mysql.connector.connect(
        host="localhost",
        user="your_username",
        password="your_password",
        database="your_dbname"
    )
    cursor = db_connection.cursor()
    cursor.execute("SELECT * FROM Market")
    market_list = cursor.fetchall()
    cursor.clos
