创建一个视频收费系统涉及到多个方面,包括前端展示、后端处理、数据库存储和支付接口集成等,下面是一个简要的实现方案,使用Python Flask作为后端框架,MySQL作为数据库,以及一些前端技术如HTML、CSS和JavaScript。
1. 环境准备
Python 3.8+
Flask
MySQL
前端技术(HTML, CSS, JavaScript)
2. 项目结构
video_charging_system/ ├── app.py ├── models.py ├── routes.py ├── requirements.txt ├── templates/ │ ├── index.html │ ├── video.html │ └── login.html ├── static/ │ ├── css/ │ ├── js/ │ └── images/ └── tests/
3.requirements.txt
Flask==2.0.1 FlaskSQLAlchemy==2.5.1 FlaskLogin==0.5.0 mysqlclient==2.1.1
4.app.py
from flask import Flask, render_template, request, redirect, url_for, flash from flask_sqlalchemy import SQLAlchemy from flask_login import LoginManager, UserMixin, login_user, logout_user, login_required, current_user app = Flask(__name__) app.config['SECRET_KEY'] = 'your_secret_key' app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+mysqlconnector://username:password@localhost/dbname' app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False db = SQLAlchemy(app) login_manager = LoginManager() login_manager.init_app(app) Import models and routes after initializing the application import models import routes if __name__ == '__main__': app.run(debug=True)
5.models.py
from app import db, login_manager from datetime import datetime from werkzeug.security import generate_password_hash, check_password_hash from flask_login import UserMixin class User(UserMixin, db.Model): id = db.Column(db.Integer, primary_key=True) username = db.Column(db.String(64), unique=True, index=True) email = db.Column(db.String(120), unique=True, index=True) password_hash = db.Column(db.String(128)) videos = db.relationship('Video', backref='uploader', lazy='dynamic') def set_password(self, password): self.password_hash = generate_password_hash(password) def check_password(self, password): return check_password_hash(self.password_hash, password) class Video(db.Model): id = db.Column(db.Integer, primary_key=True) title = db.Column(db.String(120)) content = db.Column(db.LargeBinary) upload_time = db.Column(db.DateTime, default=datetime.utcnow) uploader_id = db.Column(db.Integer, db.ForeignKey('user.id')) @login_manager.user_loader def load_user(user_id): return User.query.get(int(user_id))
6.routes.py
from app import app, db, login_manager, login_user, logout_user, login_required, current_user from flask import render_template, redirect, url_for, flash, request from models import User, Video from werkzeug.urls import url_parse from flask_login import login_user, logout_user, login_required, current_user @app.route('/') @login_required def index(): page = request.args.get('page', 1, type=int) videos = Video.query.order_by(Video.upload_time.desc()).paginate(page, app.config['POSTS_PER_PAGE'], False) next_url = url_for('index', page=videos.next_num) if videos.has_next else None prev_url = url_for('index', page=videos.prev_num) if videos.has_prev else None return render_template('index.html', videos=videos.items, next_url=next_url, prev_url=prev_url) @app.route('/login', methods=['GET', 'POST']) def login(): if request.method == 'POST': username = request.form['username'] password = request.form['password'] user = User.query.filter_by(username=username).first() if user is None or not user.check_password(password): flash('Invalid username or password') return redirect(url_for('login')) login_user(user) return redirect(url_for('index')) return render_template('login.html') @app.route('/logout') def logout(): logout_user() return redirect(url_for('index'))
7.templates/index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>Video Charging System</title> <link rel="stylesheet" href="{{ url_for('static', filename='css/styles.css') }}"> </head> <body> <div class="container"> {% for video in videos %} <div class="video"> <h2>{{ video.title }}</h2> <p>{{ video.upload_time }}</p> <! Add a way to play the video > </div> {% endfor %} <div class="pagination"> {% if prev_url %} <a href="{{ prev_url }}">Prev</a> {% endif %} {% if next_url %} <a href="{{ next_url }}">Next</a> {% endif %} </div> </div> </body> </html>
8.templates/login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>Login</title> </head> <body> <form method="post" action="/login"> <input type="text" name="username" placeholder="Username" required> <input type="password" name="password" placeholder="Password" required> <button type="submit">Login</button> </form> </body> </html>
9.static/css/styles.css
body { fontfamily: Arial, sansserif; } .container { width: 80%; margin: auto; } .video { border: 1px solid #ccc; padding: 20px; marginbottom: 20px; } .pagination { textalign: center; }
10. 初始化数据库并创建表:
在命令行中运行以下命令来创建数据库表:
flask shell >>> from models import db >>> db.create_all() # Create tables in the database >>> exit()
11. 启动应用:
在命令行中运行以下命令来启动应用:
python app.py
访问http://127.0.0.1:5000/
即可看到视频列表页面,访问http://127.0.0.1:5000/login
可以登录。
