flask装饰器的使用，带返回值并传递视图函数使用

1、在蓝图__init__.py中添加装饰器函数, 这里需要注意的是，装饰器需定义在 api初始化之前 

"""
App蓝图
"""
from flask import Blueprint, request
from flask_restful import Api


# 初始化蓝图
blue = Blueprint('blue', __name__)
api = Api(blue)


# 装饰器
def test(func):
    def deco(*args, **kwargs):
        data = "xxxx"
        res = func(*args, **kwargs, data=data)
        return res
    return deco


from .urls import URLS
# 配置url
for url in URLS:
    api.add_resource(url['component'], url['path'])

2、urls.py路由

from . import views

URLS = [
    {
        "path": "/xx/user_mark_for_app",
        "message": "测试",
        "component": views.MarkScore
    }
]

3、views.py视图

# 用户评分
class MarkScore(BaseApi):

    def post(self):
        args = user_mark_for_app_parser.parse_args()
        data = xx.user_mark_for_app(args=args)
        self.result.update(data)
        # 返回response
        return make_response(jsonify(self.result), 200)

4、params.py参数验证

from flask_restful import reqparse, inputs

# 用户评分
user_mark_for_app_parser = reqparse.RequestParser(trim=True)
user_mark_for_app_parser.add_argument('app_id', type=str, required=True, nullable=False, location=['json'])
user_mark_for_app_parser.add_argument('score', type=float, required=True, nullable=False, location=['json'])

5、handle.py主逻辑，调用装饰器

from . import test

@test
def user_mark_for_app(self, args, data):
    result = {}
    print(data)
    return result
