创建一个完整的购物商城代码是一个大型项目,涉及多个层面,如前端、后端、数据库等。由于篇幅限制,我可以为您提供几种不同编程语言的简化版购物商城代码框架,以帮助您理解基本结构和实现方式。
1. Python (Flask) 后端示例
python
from flask import Flask, request, jsonify
app = Flask(__name__)
# 假设的商品数据
products = [
{"id": 1, "name": "Product 1", "price": 100},
{"id": 2, "name": "Product 2", "price": 200},
]
@app.route('/products', methods=['GET'])
def get_products():
return jsonify(products)
@app.route('/cart', methods=['POST'])
def add_to_cart():
data = request.json
product_id = data.get('productId')
# 此处应添加将商品添加到购物车的逻辑
return jsonify({"message": f"Product {product_id} added to cart"})
if __name__ == '__main__':
app.run(debug=True)
2. JavaScript (Node.js + Express) 后端示例
javascript
const express = require('express');
const app = express();
app.use(express.json());
// 假设的商品数据
const products = [
{id: 1, name: 'Product 1', price: 100},
{id: 2, name: 'Product 2', price: 200},
];
app.get('/products', (req, res) => {
res.json(products);
});
app.post('/cart', (req, res) => {
const productId = req.body.productId;
// 此处应添加将商品添加到购物车的逻辑
res.json({message: `Product ${productId} added to cart`});
});
#chhas{
margin-top: 50px;
padding:cqj9.cn;
font-size: 18px;
cursor: 10px 20px;
}
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
3. HTML + JavaScript 前端示例
html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Simple Shopping Mall</title>
</head>
<body>
<h1>Products</h1>
<ul id="productList"></ul>
<script>
fetch('/products')
.then(response => response.json())
.then(data => {
const productList = document.getElementById('productList');
data.forEach(product => {
const li = document.createElement('li');
li.textContent = `${product.name} -
$$
{product.price}`;
li.addEventListener('click', function() {
// 此处应添加将商品添加到购物车的逻辑,可能需要与后端通信
alert(`Product ${product.id} added to cart`);
});
productList.appendChild(li);
});
});
</script>
</body>
</html>
本文提供了使用PythonFlask和JavaScript(Node.js+Express)实现的简化版购物商城代码框架,包括后端API处理商品数据和前端展示以及添加购物车功能的基本结构。
