flask_restful规范返回值之参数设置

from flask import Flask,render_template
from flask_restful import Api,Resource,fields,marshal_with

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

class News:
    def __init__(self,code,msg,info):
        self.code = code
        self.msg = msg
        self.info = info
        self.state= 1000

class NewsView(Resource):
    resouce_fileds = {
        # 通过参数default来设置默认值
        'code':fields.Integer(default=200),
        'msg':fields.String,
        # 通过参数attribute来设置提取数据的字段
        'content':fields.String(attribute='info'),
        # 优先级不如真实数据里面的高
        'state':fields.Integer(default=2000)
         }
    @marshal_with(resouce_fileds)
    def get(self):
        return News(200,'访问成功！','移动')
    
    @marshal_with(resouce_fileds)
    def post(self):
        return {'msg':'增加数据成功','info':'联通'}
    
    @marshal_with(resouce_fileds)
    def put(self):
        # 在返回对象时，会自动在对象中获取与约定好的字段，并获取分装成json
        news = News(404,'访问成功','移动')
        return news

api.add_resource(NewsView,'/news/')

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