1.使用虚拟环境Virtualenv来创建项目

 2. Flask框架介绍

Flask框架是一个用Python编写的轻量级Web应用程序框架，依赖于Werkzeug和Jinja2两个外部库。Werkzeug是一个WSGI工具包，用于接收和处理HTTP请求，匹配视图函数，支持Cookie和会话管理，交互式调试等功能。Jinja2是一个模板引擎，用于将响应结果渲染到模板文件，支持动态网页的呈现。Flask框架的核心构成简单，但具有很强的扩展性和兼容性，可以根据需要选择不同的数据库和其他功能扩展。Flask框架主要用于开发Web应用程序，例如网站或Web服务。

安装flask框架,使用以下代码,或者直接在pycharm设置的++下安装

pip install flask

 3.创建Flask项目

在终端中进入要创建项目的目录，输入以下命令创建Flask项目：

mkdir Online-Music-main
cd Online-Music-main

4. 创建Flask app  

在Online-Music-main目录下创建一个Python文件，命名为app.py

# _*_ codding:utf-8 _*_
from app import create_app, db
from app.models import *
from flask_script import Manager, Shell
from flask_migrate import Migrate, MigrateCommand
from flask import render_templateapp = create_app('default')
manager = Manager(app)
migrate = Migrate(app, db)def make_shell_context():return dict(app=app, db=db)manager.add_command("shell", Shell(make_context=make_shell_context))
manager.add_command('db', MigrateCommand)@app.errorhandler(404)
def page_not_found(error):"""404"""return render_template("home/404.html"), 404if __name__ == '__main__':manager.run()

5.配置config.py文件,连接数据库 

# -*- coding=utf-8 -*-
import os
class Config:SECRET_KEY = 'mrsoft'SQLALCHEMY_TRACK_MODIFICATIONS = True@staticmethoddef init_app(app):'''初始化配置文件'''pass# the config for development
class DevelopmentConfig(Config):SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://root:123456@127.0.0.1:3306/music'DEBUG = True# define the config
config = {'default': DevelopmentConfig
}

 6在添加models模型,

from . import db# 用户表
class User(db.Model):__tablename__ = "user"id = db.Column(db.Integer, primary_key=True)             # 编号username = db.Column(db.String(100))                     # 用户名pwd = db.Column(db.String(100))                          # 密码flag = db.Column(db.Boolean,default=0)                   # 用户标识，0：普通用户 1：管理员def __repr__(self):return '<User %r>' % self.namedef check_pwd(self, pwd):"""检测密码是否正确:param pwd: 密码:return: 返回布尔值"""return self.pwd == pwd# 歌手表
class Artist(db.Model):__tablename__ =  'artist'id = db.Column(db.Integer, primary_key=True)             # 编号artistName = db.Column(db.String(100))                    # 歌手名style = db.Column(db.Integer)                             # 歌手类型imgURL = db.Column(db.String(100))                        # 头像isHot = db.Column(db.Boolean,default=0)                   # 是否热门# 歌曲表
class Song(db.Model):__tablename__ = 'song'id = db.Column(db.Integer, primary_key=True)              # 编号songName = db.Column(db.String(100))                      # 歌曲名称singer = db.Column(db.String(100))                        # 歌手名称fileURL = db.Column(db.String(100))                       # 歌曲图片hits = db.Column(db.Integer,default=0)                    # 点击量style = db.Column(db.Integer)                             # 歌曲类型 0：全部 1:华语 2：欧美 3：日语 4：韩语 5 其他collect = db.relationship('Collect', backref='song')      # 收藏外键关系关联# 歌曲收藏
class Collect(db.Model):__tablename__ = "collect"id = db.Column(db.Integer, primary_key=True)              # 编号song_id = db.Column(db.Integer, db.ForeignKey('song.id')) # 所属歌曲user_id = db.Column(db.Integer)                           # 所属用户

7.写视图views.py,最后渲染前端网页实现界面

# _*_ coding: utf-8 _*_

</body>
</html>

最后运行python app.py runserver

因为前端网页页面有点多,需要源代码可以私信博主

1.3  论文结构与章节安排

• 绪论。主要讲述了对于当前音乐网的调研情况，介绍了此课题提出的背景和研究的意义，
•  相关介绍。介绍了此音乐网系统开发时所用的框架Flask和新型技术ORM作详细介绍。
• 需求分析。本章根据中国网数据得知，当前音乐网的发展趋势蓬勃发展，然后确定音乐网系统的总体需求，然后介绍开发音乐网所用到的开发工具做了详细概述。
• 系统概要设计。本章基于第三章的需求对音乐网管理系统作了全面的设计，首先设计了系统的总体架构，然后对音乐网管理系统的功能设计重点的作了介绍，接着对该套系统的数据库和ORM模型作了设计，最后系统的安全性作了分析。系统实现。按照系统的需求和设计说明书，实现了在线音乐网系统所有的功能模块。
• 数据库设计。介绍了在线音乐网数据库里面的数据表
