Python 代码实现高性能异构分布式并行智慧商铺管理系统

用户管理模块（User Management Module）：

管理商铺员工和客户的身份验证、权限分配、账户管理等功能。

# User Management Module

class User:
    def __init__(self, user_id, username, role):
        self.user_id = user_id
        self.username = username
        self.role = role

class UserManager:
    def __init__(self):
        self.users = {}

    def add_user(self, user_id, username, role):
        user = User(user_id, username, role)
        self.users[user_id] = user
        print(f"User {username} added with role {role}.")

    def authenticate(self, user_id, username):
        user = self.users.get(user_id)
        if user and user.username == username:
            print(f"User {username} authenticated successfully.")
            return True
        else:
            print(f"Authentication failed for user {username}.")
            return False

    def assign_role(self, user_id, new_role):
        if user_id in self.users:
            self.users[user_id].role = new_role
            print(f"Role of user {user_id} updated to {new_role}.")
        else:
            print(f"User {user_id} not found.")

# Example usage:
user_manager = UserManager()
user_manager.add_user(1, "admin", "manager")
user_manager.authenticate(1, "admin")
user_manager.assign_role(1, "supervisor")

商品管理模块（Product Management Module）：

负责商品的添加、删除、库存管理、价格更新等功能。

# Product Management Module

class Product:
    def __init__(self, product_id, name, price, stock):
        self.product_id = product_id
        self.name = name
        self.price = price
        self.stock = stock

class ProductManager:
    def __init__(self):
        self.products = {}

    def add_product(self, product_id, name, price, stock):
        product = Product(product_id, name, price, stock)
        self.products[product_id] = product
        print(f"Product {name} added with ID {product_id}.")

    def update_stock(self, product_id, new_stock):
        if product_id in self.products:
            self.products[product_id].stock = new_stock
            print(f"Stock of product {product_id} updated to {new_stock}.")
        else:
            print(f"Product {product_id} not found.")

    def update_price(self, product_id, new_price):
        if product_id in self.products:
            self.products[product_id].price = new_price
            print(f"Price of product {product_id} updated to {new_price}.")
        else:
            print(f"Product {product_id} not found.")

# Example usage:
product_manager = ProductManager()
product_manager.add_product(101, "Laptop", 999.99, 10)
product_manager.update_stock(101, 15)
product_manager.update_price(101, 949.99)

订单处理模块（Order Processing Module）：

处理客户订单，包括订单创建、更新、支付、物流跟踪等功能。

# Order Processing Module

class Order:
    def __init__(self, order_id, user_id, product_id, quantity, status="pending"):
        self.order_id = order_id
        self.user_id = user_id
        self.product_id = product_id
        self.quantity = quantity
        self.status = status

class OrderManager:
    def __init__(self):
        self.orders = {}

    def create_order(self, order_id, user_id, product_id, quantity):
        order = Order(order_id, user_id, product_id, quantity)
        self.orders[order_id] = order
        print(f"Order {order_id} created for user {user_id}.")

    def update_order_status(self, order_id, new_status):
        if order_id in self.orders:
            self.orders[order_id].status = new_status
            print(f"Order {order_id} status updated to {new_status}.")
        else:
            print(f"Order {order_id} not found.")

# Example usage:
order_manager = OrderManager()
order_manager.create_order(201, 1, 101, 2)
order_manager.update_order_status(201, "shipped")

数据分析模块（Data Analytics Module）：

# Data Analytics Module

class DataAnalytics:
    def __init__(self, orders, products):
        self.orders = orders
        self.products = products

    def sales_report(self):
        report = {}
        for order in self.orders.values():
            product_name = self.products[order.product_id].name
            report[product_name] = report.get(product_name, 0) + order.quantity
        return report

    def customer_order_history(self, user_id):
        history = [order for order in self.orders.values() if order.user_id == user_id]
        return history

# Example usage:

print(analytics.sales_report())
print(analytics.customer_order_history(1))

分布式计算模块（Distributed Computing Module）：

管理不同节点之间的任务分发与调度，实现并行计算以提高性能。

# Distributed Computing Module

from multiprocessing import Pool

class DistributedTaskManager:
    def __init__(self):

    def execute_task(self, task, data):
        result = self.pool.apply_async(task, (data,))
        return result.get()

def example_task(data):
    return sum(data)

# Example usage:
task_manager = DistributedTaskManager()
result = task_manager.execute_task(example_task, [1, 2, 3, 4, 5])
print(f"Task result: {result}")

通信模块（Communication Module）：

负责不同模块和节点之间的通信，包括RPC（远程过程调用）和消息队列等。

# Communication Module

import socket

class CommunicationManager:
    def __init__(self, host, port):
        self.host = host
        self.port = port

    def send_message(self, message):
        with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
            s.connect((self.host, self.port))
            s.sendall(message.encode())
            response = s.recv(1024)
            return response.decode()

# Example usage:
comm_manager = CommunicationManager('localhost', 8080)
response = comm_manager.send_message('Hello, Server!')
print(f"Received: {response}")

数据库管理模块（Database Management Module）：

管理商铺的数据库操作，包括数据存储、检索、备份等功能。

# Database Management Module

import sqlite3

class DatabaseManager:
    def __init__(self, db_name):
        self.connection = sqlite3.connect(db_name)
        self.cursor = self.connection.cursor()

    def create_table(self, table_name, schema):
        self.cursor.execute(f"CREATE TABLE IF NOT EXISTS {table_name} ({schema})")
        self.connection.commit()

    def insert_record(self, table_name, values):
        placeholders = ', '.join('?' * len(values))
        self.cursor.execute(f"INSERT INTO {table_name} VALUES ({placeholders})", values)
        self.connection.commit()

    def query_records(self, table_name):
        self.cursor.execute(f"SELECT * FROM {table_name}")
        return self.cursor.fetchall()

# Example usage:
db_manager = DatabaseManager('shop.db')
db_manager.create_table('products', 'id INTEGER PRIMARY KEY, name TEXT, price REAL, stock INTEGER')
db_manager.insert_record('products', (101, 'Laptop', 999.99, 10))
print(db_manager.query_records('products'))

安全模块（Security Module）：

实现数据加密、身份验证、权限管理、日志记录等安全功能。

# Security Module

import hashlib

class SecurityManager:
    def hash_password(self, password):
        salt = "somesecretsalt"
        return hashlib.sha256((password + salt).encode()).hexdigest()

    def verify_password(self, password, hashed):
        return self.hash_password(password) == hashed

# Example usage:
security_manager = SecurityManager()
hashed_pw = security_manager.hash_password('securepassword')
print(f"Hashed Password: {hashed_pw}")
print("Password Match:", security_manager.verify_password('securepassword', hashed_pw))
