flask的cbv-526互联

eg:

# cbv：基于类的视图  MethodView 继承自 View
from flask import Flask,render_template
from flask.views import MethodView
app = Flask(__name__,template_folder='templates')

# 3 写个装饰器
def auth(func):
    def inner(*args,**kwargs):
        print('装饰器执行了')
        ret = func(*args,**kwargs)
        return ret
    return inner

# 1 定义类
class Home(MethodView):

    decorators = [auth] # 使用装饰器 decorators类似一个列表
    # 4控制允许的请求方式
    methods = ['GET'] # 只允许get请求
    def get(self):
        return render_template('home.html')
    def post(self):
        return 'cbv'
# 2 注册路由

app.add_url_rule('/home',view_func=Home.as_view('home'))


if __name__ == '__main__':
    app.run(port=8080)
