from flask import render_template   #导入render_template，叫渲染模板，帮助把想要的渲染文件给展示出来
from flask_bootstrap import Bootstrap  #导入Bootstrap

#Flask类接收一个参数__name__
app = Flask(__name__)   #初始化了一个对象，叫app
bootstrap = Bootstrap(app)   #初始化flask_bootstrap



#首页
@app.route('/user/<name>')
def user(name):  #函数的名字可以随便起，只要符合python函数的命名规则就行
    return render_template('bs/user.html',
                           name=name
                           )





#Flask应用程序实例的run方法启动web服务器
