Flask入门笔记-14_在类视图中使用装饰器

• 在类视图中,通过类属性method_decorators来设置类视图的装饰器,如果接收一个列表那类视图内所有的方法都使用列表中的装饰器

• 如果接收一个字典:请求方式为k, 列表为v,列表中放装饰器名称, 注意顺序

from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

# 装饰器1
def decorator1(f):
    def warpper(*args, **kwargs):
        print('decorator1')
        return f(*args, **kwargs)
    return warpper

# 装饰器2
def decorator2(f):
    def warpper(*args, **kwargs):
        print('decorator2')
        return f(*args, **kwargs)
    return warpper

class demo(Resource):
    # method_decorators = [decorator1]  # 让所有的请求方式都使用decorator1装饰器
    method_decorators = { # 指定方法使用指定装饰器
        'get':[decorator1, decorator2],
        'post':[decorator1]
    }

    def get(self):
        return {'demo':'get'}

    def post(self):
        return {'demo':'post'}

    def put(self):
        return {'demo':'put'}

api.add_resource(demo, '/')


if __name__ == '__main__':
    app.run(host='0.0.0.0', port='8000')
