python实现机票订购系统代码

实现机票订购系统需要用到多个Python库，包括但不限于Flask、Django、SQLAlchemy等，具体实现方式也因项目不同而异。以下是一个简单的机票订购系统代码示例，以Flask为例：

from flask import Flask, render_template, request, redirect, url_for
from datetime import datetime
from sqlalchemy import create_engine, Column, Integer, String, DateTime, ForeignKey
from sqlalchemy.orm import sessionmaker, relationship
from sqlalchemy.ext.declarative import declarative_base

app = Flask(__name__)
engine = create_engine('sqlite:///flight.db', echo=True)
Base = declarative_base()
Session = sessionmaker(bind=engine)
session = Session()

# 定义机票信息表
class Flight(Base):
    __tablename__ = 'flight'
    id = Column(Integer, primary_key=True)
    flight_no = Column(String)
    departure = Column(String)
    destination = Column(String)
    departure_time = Column(DateTime)
    arrival_time = Column(DateTime)
    price = Column(Integer)

# 定义订单信息表
class Order(Base):
    __tablename__ = 'order'
    id = Column(Integer, primary_key=True)
    flight_id = Column(Integer, ForeignKey('flight.id'))
    user_name = Column(String)
    user_phone = Column(String)
    user_email = Column(String)
    create_time = Column(DateTime, default=datetime.now)
    flight = relationship('Flight', backref='orders')

# 定义用户信息表
class User(Base):
    __tablename__ = 'user'
    id = Column(Integer, primary_key=True)
    name = Column(String)
    email = Column(String)
    password = Column(String)

# 首页
@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        departure = request.form['departure']
        destination = request.form['destination']
        departure_time = datetime.strptime(request.form['departure_time'], '%Y-%m-%d %H:%M:%S')
        flights = session.query(Flight).filter(
            Flight.departure == departure,
            Flight.destination == destination,
            Flight.departure_time >= departure_time
        ).all()
        return render_template('flight_list.html', flights=flights)
    return render_template('index.html')

# 机票列表页
@app.route('/flight_list')
def flight_list():
    flight_id = request.args['flight_id']
    flight = session.query(Flight).get(flight_id)
    return render_template('order.html', flight=flight)

# 订单页
@app.route('/order', methods=['POST'])
def order():
    flight_id = request.form['flight_id']
    user_name = request.form['user_name']
    user_phone = request.form['user_phone']
    user_email = request.form['user_email']
    flight = session.query(Flight).get(flight_id)
    order = Order(flight=flight, user_name=user_name, user_phone=user_phone, user_email=user_email)
    session.add(order)
    session.commit()
    return redirect(url_for('success'))

# 订单成功页
@app.route('/success')
def success():
    return render_template('success.html')

if __name__ == '__main__':
    Base.metadata.create_all(engine)
    app.run(debug=True)

以上代码仅为示例，实现机票订购系统需要根据具体需求进行更改和完善。
