}
def get_cover_image(self):
cover = self.images.filter_by(is_cover=True).first()
if cover:
return cover.image_url
image = self.images.first()
return image.image_url if image else ''
3.2.3 交易流程实现
# app/models/order.py
from app import db
from datetime import datetime
class Order(db.Model):
__tablename__ = 'orders'
id = db.Column(db.Integer, primary_key=True)
item_id = db.Column(db.Integer, db.ForeignKey('items.id'))
seller_id = db.Column(db.Integer, db.ForeignKey('users.id'))
buyer_id = db.Column(db.Integer, db.ForeignKey('users.id'))

# app/socket.py
from flask_socketio import SocketIO, emit, join_room, leave_room
from flask_login import current_user
from app import socketio, db
from app.models import Message, User
@socketio.on('connect')
def handle_connect():
if current_user.is_authenticated:
join_room(current_user.id)
emit('response', {'data': '连接成功'})
@socketio.on('send_message')
def handle_send_message(data):
if current_user.is_authenticated:
receiver_id = data.get('receiver_id')
content = data.get('content')
# 保存消息到数据库
message = Message(
sender_id=current_user.id,
receiver_id=receiver_id,
content=content
)
db.session.add(message)
db.session.commit()
# 发送消息给接收者
emit('new_message', {
'id': message.id,
'sender_id': current_user.id,
'sender_name': current_user.username,
'content': content,
'create_time': message.create_time.strftime('%Y-%m-%d %H:%M:%S')
}, room=receiver_id)
3.3 系统安全性实现
3.3.1 用户密码加密
使用Werkzeug提供的安全哈希函数对用户密码进行加密存储，确保即使数据库泄露，用户密码也不会被直接获取。
3.3.2 CSRF防护
使用Flask-WTF提供的CSRF保护功能，防止跨站请求伪造攻击。
# app/__init__.py
from flask_wtf.csrf import CSRFProtect
csrf = CSRFProtect()
def create_app(config_name):
app = Flask(__name__)
# ...
csrf.init_app(app)
# ...
return app
3.3.3 XSS防护
使用Jinja2模板引擎的自动转义功能，防止跨站脚本攻击。
<!-- 在模板中安全地显示用户输入内容 -->
<div class="item-description">{{ item.description|safe }}</div>
3.3.4 SQL注入防护
使用SQLAlchemy ORM，避免直接拼接SQL语句，防止SQL注入攻击。
# 安全的查询方式
items = Item.query.filter(Item.title.like(f'%{keyword}%')).all()
# 不安全的查询方式（避免使用）
# items = db.session.execute(f"SELECT * FROM items WHERE title LIKE '%{keyword}%'").fetchall()
3.4 性能优化
3.4.1 数据库优化
- 为常用查询字段添加索引
- 使用连接池管理数据库连接
- 对大表进行分区
# 为常用查询字段添加索引
class Item(db.Model):
__tablename__ = 'items'
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), index=True) # 添加索引
category_id = db.Column(db.Integer, db.ForeignKey('categories.id'), index=True) # 添加索引
user_id = db.Column(db.Integer, db.ForeignKey('users.id'), index=True) # 添加索引
status = db.Column(db.Integer, default=0, index=True) # 添加索引
3.4.2 缓存优化
使用Redis缓存热门商品、首页数据等，减轻数据库压力。
# app/utils/cache.py
import redis
import json
redis_client = redis.Redis(host='localhost', port=6379, db=0)
def set_cache(key, value, expire=3600):
"""设置缓存"""
if isinstance(value, (dict, list)):
value = json.dumps(value)
redis_client.set(key, value, ex=expire)
def get_cache(key):
"""获取缓存"""
value = redis_client.get(key)
if value:
try:
return json.loads(value)
except:
return value.decode('utf-8')
return None
def clear_cache(pattern):
"""清除匹配模式的缓存"""
keys = redis_client.keys(pattern)
if keys:
redis_client.delete(*keys)
3.4.3 搜索优化
使用Elasticsearch实现全文搜索，提高搜索效率和准确性。
# app/utils/search.py
from elasticsearch import Elasticsearch
from app.models import Item
es = Elasticsearch(['http://localhost:9200'])
def index_item(item):
"""索引商品数据"""
doc = {
'id': item.id,
'title': item.title,
'description': item.description,
'price': item.price,
'category_id': item.category_id,
'status': item.status,
'create_time': item.create_time.strftime('%Y-%m-%d %H:%M:%S')
}
es.index(index='items', id=item.id, body=doc)
def search_items(keyword, page=1, per_page=10):
"""搜索商品"""
query = {
'query': {
'multi_match': {
'query': keyword,
'fields': ['title^3', 'description'] # 标题权重更高
}
},
'from': (page - 1) * per_page,
'size': per_page
}
result = es.search(index='items', body=query)
return result['hits']

5. 系统测试
5.1 单元测试
使用Python的unittest框架对各个模块进行单元测试，确保每个功能模块的正确性。
# tests/test_user_model.py
import unittest
from app import create_app, db
from app.models import User
class UserModelTestCase(unittest.TestCase):
def setUp(self):
self.app = create_app('testing')
self.app_context = self.app.app_context()
self.app_context.push()
db.create_all()
def tearDown(self):
db.session.remove()
db.drop_all()
self.app_context.pop()
def test_password_setter(self):
u = User(password='cat')
self.assertTrue(u.password_hash is not None)
def test_no_password_getter(self):
u = User(password='cat')
with self.assertRaises(AttributeError):
u.password
def test_password_verification(self):
u = User(password='cat')
self.assertTrue(u.verify_password('cat'))
self.assertFalse(u.verify_password('dog'))
5.2 接口测试
使用Postman或Python的requests库对API接口进行测试，确保接口的正确性和稳定性。
# tests/test_api.py
import unittest
import json
from app import create_app, db
from app.models import User, Item
class APITestCase(unittest.TestCase):
def setUp(self):
self.app = create_app('testing')
self.app_context = self.app.app_context()
self.app_context.push()
db.create_all()
self.client = self.app.test_client()
def tearDown(self):
db.session.remove()
db.drop_all()
self.app_context.pop()
def test_get_items(self):
# 创建测试数据
user = User(username='test', email='test@example.com', password='password')
db.session.add(user)
item = Item(title='Test Item', description='Test Description', price=100, user_id=1)
db.session.add(item)
db.session.commit()
# 测试获取商品列表接口
response = self.client.get('/api/items')
self.assertEqual(response.status_code, 200)
data = json.loads(response.data)
self.assertEqual(len(data['items']), 1)
self.assertEqual(data['items'][0]['title'], 'Test Item')
5.3 性能测试
使用Apache JMeter或Locust对系统进行性能测试，评估系统在高并发情况下的表现。
# locustfile.py
from locust import HttpUser, task, between
class WebsiteUser(HttpUser):
wait_time = between(1, 5)
@task(2)
def index(self):
self.client.get("/")
@task(1)
def view_item(self):
item_id = 1
self.client.get(f"/items/{item_id}")
@task(1)
def search_items(self):
self.client.get("/search?keyword=book")
