1. 安装与配置python3.6+flask+mysql数据库
    1. 下载安装MySQL数据库
    2. 下载安装MySQL-python 中间件
    3. pip install flask-sqlalchemy (Python的ORM框架SQLAlchemy)
  2. mysql创建数据库
  3. 数据库配置信息config.py
    SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://root:@localhost:3306/wuwen?charset=utf8'
    SQLALCHEMY_TRACK_MODIFICATIONS = False
  4. 建立mysql和app的连接
  5. 创建用户模型
    from flask import Flask,render_template
    from flask_sqlalchemy import SQLAlchemy
    import config
    
    app = Flask(__name__)
    app.config.from_object(config)
    
    db=SQLAlchemy(app)
    
    class User(db.Model):
        __tablename__='user'
        id = db.Column(db.Integer,primary_key=True,autoincrement=True)
        username = db.Column(db.String(20),nullable=False)
        password = db.Column(db.String(20), nullable=False)
        nickname = db.Column(db.String(20))
    
    db.create_all()
    
    @app.route('/')
    def base():
        return render_template('base.html')
    
    @app.route('/login/')
    def login():
        return render_template('login.html')
    
    @app.route('/regist/')
    def regist():
        return render_template('regist.html')
    
    @app.route('/question/')
    def question():
        return render_template('question.html')
    
    if __name__ == '__main__':
        app.run(debug=True)
