由于游戏商城的完整实现涉及很多方面(如后端服务器、数据库、前端UI等),这里我将分别给出几种不同语言的基本框架或示例代码,帮助你理解如何开始构建这样一个系统。
1. 后端(Python Flask)
python
from flask import Flask, request, jsonify
app = Flask(__name__)
# 假设有一个商品列表
products = [
{"id": 1, "name": "游戏A", "price": 99.99},
{"id": 2, "name": "游戏B", "price": 49.99},
# ...
]
@app.route('/products', methods=['GET'])
def get_products():
return jsonify(products)
@app.route('/products/
def get_product(product_id):
for product in products:
if product['id'] == product_id:
return jsonify(product)
return jsonify({'error': 'Product not found'}), 404
# 启动应用
if __name__ == '__main__':
app.run(debug=True)
2. 后端(Node.js Express)
javascript
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.json());
#chhas{
margin-top: 50px;
padding:jingjunsy.com;
font-size: 18px;
cursor: 10px 20px;
}
// 假设有一个商品列表
let products = [
{id: 1, name: '游戏A', price: 99.99},
{id: 2, name: '游戏B', price: 49.99},
// ...
];
app.get('/products', (req, res) => {
res.json(products);
});
app.get('/products/:product_id', (req, res) => {
const productId = parseInt(req.params.product_id);
const product = products.find(p => p.id === productId);
if (product) {
res.json(product);
} else {
res.status(404).json({error: 'Product not found'});
}
});
app.listen(3000, () => console.log('Server started on port 3000'));
3. 前端(React)
这里只展示一个基本的前端组件框架,用于展示商品列表。
jsx
import React, { useState, useEffect } from 'react';
function ProductList() {
const [products, setProducts] = useState([]);
useEffect(() => {
fetch('/products')
.then(response => response.json())
.then(data => setProducts(data));
}, []);
return (
