开始Flask项目

  1. 新建Flask项目。
  2. 设置调试模式。
  3. 理解Flask项目主程序。
  4. 使用装饰器，设置路径与函数之间的关系。
  5. 使用Flask中render_template，用不同的路径，返回首页、登录员、注册页。
  6. 用视图函数反转得到URL，url_for(‘login’)，完成导航里的链接
    1. mis1103.py
  7. from flask import Flask,render_template

app = Flask(__name__)


@app.route('/')
def index():
    return render_template('index.html')

@app.route('/login/')
def login():
    return render_template('login.html')

@app.route('/zhuce/')
def zhuce():
    return render_template('zhuce.html')

if __name__ == '__main__':
    app.run(debug=True)
